Class Description

Class Interface, Class INode, Animatable Flags, Class IGraphObjectManager, Class IGraphNode, Class Object

Description:

This is the base class for all animatable scene entity types, and for most plugin types. Methods are available for getting the ClassID and SuperClassID of the plug-in, deleting this instance of the plug-in class, and parameter editing in the command panel. There are also methods that deal with the sub-animatables of the plug-in. Most of the track view related methods are here as well.

Data Members:

protected:

unsigned long aflag;

The flags. These may be manipulated using the methods SetAFlag(), ClearAFlag(), and TestAFlag(). See List of Animatable Flags.

AnimPropertyList aprops;

This is a table of properties that a plug-in may use for its own storage needs. This table is also used by the system (for example Note Tracks and APP_DATA). A plug-in may use this, for example, when a class has some data that is used while its user interface is up. It can store the UI data on the property list temporarily and not have to carry around the data when it is not needed. See the methods of Template Class Tab for how to add and delete items from the list. Also see the methods GetProperty() and SetProperty() and Class AnimPropertyList. Note that it's not safe to copy Animatable objects because the properties held in AnimPropertyList do not have a well-defined copy semantics

Constructor & Destructor Documentation

virtual CoreExport ~Animatable ( )

protectedpure virtual

Destructor.

Instances of class Animatable and classes directly derived from it should be deleted by calling Animatable::DeleteThis() on them, rather then calling the delete operator.

CoreExport Animatable

(

)

Constructor.

Member Function Documentation

virtual CoreExport void DeleteThis ( )

virtual

Deletes an instance of this class.

3ds Max calls this method when it needs to delete a plugin object (an instance of a class derived from Animatable). Similarly, plugins that need to delete instances of an Animatable or a class directly derived from it via an Animatable pointer, should call this method instead of calling directly operator delete. Following these rules will ensure that the same memory manager is used to allocate and deallocate the object. The default implementation of this method deletes the object. Plugin instances that never need to be deleted from the heap can overwrite this method to do nothing.

Note

See the method ClassDesc::Create() for details on how Max allocates plugin objects.

See ReferenceMaker::DeleteMe() and ReferenceTarget::MaybeAutoDelete() for information on how plugin instances are deleted by the system.

Remarks

See Memory Management.

virtual void GetClassName ( MSTR &  s )

inlinevirtual

Retrieves the (localizable) name of the plugin class.

This name is usually used internally for debugging purposes. For Material plug-ins this method is used to put up the material "type" name in the Material Editor.

Parameters

s	Reference to a string filled in with the name of the plugin class

virtual CoreExport SClass_ID SuperClassID ( )

pure virtual

Retrieves a constant representing the type of the plugin.

Returns

A super class id that uniquely identifies the type (category) of the plugin. Note that several plugin classes can be of the same type, thus return the same super class id. Plugins are uniquely identified by their class ids.

static CoreExport BOOL IsDeleted ( Animatable *  anim )

static

Debug method to determine whether an object has been deleted.

This method checks whether an object is alive in memory, or is deleted and is a dangling pointer. The check is not perfectly accurate. A result of TRUE is guaranteed to be accurate - the object is deleted - however a result of FALSE may be inaccurate. This method should be used together with other tools to aid in debugging and bulletproofing.

Parameters

anim	The Animatable object

Returns

Returns TRUE if the object is invalid, FALSE if state is uncertain

static CoreExport AnimHandle GetHandleByAnim ( Animatable *  anim )

static

Get the unique handle for an Animatable object.

Every Animatable is given a handle value when allocated. The values are unique within a scene, but are not saved with the scene, and no guarantees are provided about handle values from one load to another. Handles are intended for use as sort/hash keys, when load and save are not required. They are safer than pointers, since the Animatable may be deleted, in which case the handle value is never reused for another Animatable within the current session, and searching for the Animatable via GetAnimByHandle() simply yields NULL.

Parameters

anim	The Animatable object

Returns

The unique handle value for the Animatable

static CoreExport Animatable* GetAnimByHandle ( AnimHandle  handle )

static

Get an Animatable object from its unique handle.

Every Animatable is given a handle value when allocated. The values are unique within a scene, but are not saved with the scene, and no guarantees are provided about handle values from one load to another. Handles are intended for use as sort/hash keys, when load and save are not required. They are safer than pointers, since the Animatable may be deleted, in which case the handle value is never reused for another Animatable within the current session, and searching for the Animatable via GetAnimByHandle() simply yields NULL.

Parameters

handle

The unique handle value for the Animatable

Returns

The Animatable object, or NULL if the Animatable has been deleted, or if the handle is invalid

void SetAFlag ( DWORD  mask )

            return (aflag_ex & mask) != 0; 
        }

static CoreExport int RequestFlagBit ( )

static

Requests an unique flag bit index.

The flag bit index is used with the Animatable::TestFlagBit(), Animatable::SetFlagBit(), Animatable::ClearFlagBit(), and Animatable::ClearFlagBitInAllAnimatables() methods. The flag bit index must be released using the Animatable::ReleaseFlagBit() method. The intended usage of the flag bit index is in enumerations where you want to visit each Animatable only once, and the usage of the flag bit is of a temporary, short term usage. The flag bits are not saved with the Animatable, nor copied via the assign operator. The flag bits referred to for these methods are not associated with the aflag or aflag_ex data members.

Returns

The unique flag bit index

static CoreExport void ReleaseFlagBit ( int  index )

static

Releases the flag bit index.

Parameters

index

The flag bit index to release

CoreExport bool TestFlagBit

(

int

index

)

Tests the specified flag bit.

Parameters

index

The flag bit index to test

Returns

TRUE if the flag bit is set

CoreExport void SetFlagBit	(	int	index,
		bool	newValue = true
	)

Sets the specified flag bit.

Parameters

index	The flag bit index to set
newValue	The value to set the flag bit index to

CoreExport void ClearFlagBit

(

int

index

)

Clears the specified flag bit.

Parameters

index

The flag bit index to clear

static CoreExport void ClearFlagBitInAllAnimatables ( int  index )

static

Clears the specified flag bit in all Animatables.

Parameters

index

The flag bit index to clear

static CoreExport void EnumerateAllAnimatables ( EnumAnimList &  enumProcObject )

static

Enumerator to enumerate across all animatables.

Implemented by the System. The Animatables are enumerated in order of creation. Use Animatable::EnumAnimTree when the enumerating the Animatables based on their hierarchy is required. EnumerateAllAnimatables is designed to be safe with recursive calls to EnumerateAllAnimatables, and is designed to be safe when Animatables are added/deleted during an enumeration.

Parameters

enumProcObject

- The callback object called for each animatable.

virtual void FreeCaches ( )

inlinevirtual

Remarks

This is called to delete any item that can be rebuilt. For example, the procedural sphere object has a mesh that it caches. It could call Mesh::FreeAll() on the mesh from this method. This will free the vertex/face/uv arrays. If the sphere is ever evaluated again it can just rebuild the mesh. If an object (like a sphere) has modifiers applied to it, and those modifiers are not animated, then the result of the pipeline is cached in the node. So there is no reason for the sphere to also have a cache of its representation. Therefore when this method is called, the sphere can free the data of the mesh.

virtual void BeginEditParams ( IObjParam *  ip, ULONG  flags, Animatable *  prev = NULL  )

inlinevirtual

Remarks

This method is called by the system when the user may edit the item's (object, modifier, controller, etc.) parameters.

Parameters

ip	Interface pointer. The developer can use it to call methods such as AddRollupPage(). Note that this pointer is only valid between BeginEditParams() and EndEditParams(). It should not be used outside this interval.
flags	Describe which branch of the command panel or dialog the item is being edited in. The following are possible values: BEGIN_EDIT_CREATE Indicates an item is being edited in the create branch. BEGIN_EDIT_MOTION Indicates a controller is being edited in the motion branch. BEGIN_EDIT_HIERARCHY Indicates a controller is being edited in the Pivot subtask of the hierarchy branch. BEGIN_EDIT_IK Indicates a controller is being edited in the IK subtask of the hierarchy branch. BEGIN_EDIT_LINKINFO Indicates a controller is being edited in the Link Info subtask of the hierarchy branch.
prev	Pointer to an Animatable object. This parameter may be used in the motion and hierarchy branches of the command panel. This pointer allows a plug-in to look at the ClassID of the previous item that was being edited, and if it is the same as this item, to not replace the entire UI in the command panel, but simply update the values displayed in the UI fields. This prevents the UI from 'flickering' when the current item begins its edit. For example, if you are in the motion branch and are looking at an item's PRS controller values, and then select another item that is displayed with a PRS controller, the UI will not change - only the values displayed in the fields will change. If however you selected a target camera that has a lookat controller (not a PRS controller) the UI will change because a different set of parameters need to be displayed. Note that for items that are edited in the modifier branch this field can be ignored.

virtual void EndEditParams ( IObjParam *  ip, ULONG  flags, Animatable *  next = NULL  )

inlinevirtual

Remarks

This method is called when the user is finished editing an objects parameters. The system passes a flag into the EndEditParams() method to indicate if the rollup page should be removed. If this flag is TRUE, the plug-in must un-register the rollup page, and delete it from the panel.

Parameters

ip	An interface pointer. The developer may use the interface pointer to call methods such as DeleteRollupPage().
flags	The following flag may be set: END_EDIT_REMOVEUI If TRUE, the item's user interface should be removed.
next	Animatable pointer. Can be used in the motion and hierarchy branches of the command panel. It allows a plug-in to look at the ClassID of the next item that was being edited, and if it is the same as this item, to not replace the entire UI in the command panel. Note that for items that are edited in the modifier branch this field can be ignored.

virtual CoreExport void* GetInterface ( ULONG  id )

virtual

Remarks

This method provides a mechanism for extending the class in the future. In 3ds Max 4.0 there are new interfaces that are accessed by passing an id to this method and it will respond by returning the corresponding interface pointer.

This method has been used however for a different purpose. It currently is used to determine if an object is of a particular class. With controllers for example, there is one base class Control, however there are many super classes (CTRL_FLOAT_CLASS_ID, CTRL_SCALE_CLASS_ID, etc.). If you wanted to find out if a given Animatable was a controller you would need to compare its SuperClassID to all the known types and only if it wasn't one of the known types could you be sure it wasn't a controller. Having to do this is inconvenient for a developer.

Instead the Control class implements this method. It looks at the id, and if it matches a predefined constant I_CONTROL, it returns its this pointer. In this way, given any Animatable, it is easy to find out if it is a controller by simply asking for the control interface. There is a macro that does this:

#define GetControlInterface(anim)
((Control*)anim-\>GetInterface(I_CONTROL))

A plug-in developer may use this macro as follows:

Control *c = GetControlInterface(anim);

This will either be NULL or a pointer to a valid controller.

Note: Plug-in defined interfaces should be greater than the following value:

#define I_USERINTERFACE 0x0000ffff

If a plug-in implements this method for its own purposes, it would, in general, switch on the id and if it is not aware of the id it would call this method on the base class. Otherwise it could respond to the id as it needed. See the sample code below for the how the Control class implements this method.

Parameters

id	The id of the interface.

Default Implementation:

{ return NULL; }

Sample Code:

The following is the Control class implementation of this method. It looks at the id passed, and if it matches I_CONTROL it returns its this pointer. Otherwise it calls the base class method.

void* Control::GetInterface(ULONG id)
{
    if (id==I_CONTROL) {
        return this;
    }
    else {
        return Animatable::GetInterface(id);
    }

virtual CoreExport void ReleaseInterface ( ULONG  id, void *  i  )

virtual

Remarks

This method is not currently used. It is reserved for future use. Its purpose is for releasing an interface created with GetInterface().

Reimplemented in MaxBakeElement, MaxRenderElement, IRenderElement, and TriObject.

virtual CoreExport BaseInterface* GetInterface ( Interface_ID  id )

virtual

Remarks

Returns a pointer to the Base Interface for the interface ID passed. The default implementation of this method retrieves this information from the ClassDesc for the plug-in.

Any future object-based interfaces should be allocated unique Interface_IDs (you can use Gencid.exe for this) and made available through this call.

The default implementation of GetInterface(Interface_ID) looks up a standalone interface of the given ID on the object's ClassDesc. This gives access to standalone interfaces via any of a plug-in's objects, without having to dig around for the ClassDesc, so you should fall back to calling the default implementation if you don't recognize an ID in your implementation of GetInterface(Interface_ID).

Parameters

id	The unique ID of the interface to get. See Class Interface_ID.

virtual CoreExport int SetProperty ( ULONG  id, void *  data  )

virtual

Remarks

This is a general method for adding properties, when defining a new Interface would be too cumbersome. This method provides another way to extend the class without actually adding any methods. Sample code that implements this method to add properties to the property list is in /MAXSDK/SAMPLES/CONTROLLERS/PATHCTRL.CPP. See below.

Parameters

id	The id for the property.
data	A pointer to the data to store.

Returns

Nonzero if the property was set; otherwise zero.

Default Implementation:

{ return 0; }

Sample Code:

This code is from /MAXSDK/SAMPLES/CONTROLLERS/path_cnstrnt.cpp. It is used to save the inverse kinematics user interface parameters of the path controller. It saves the property data on the aprops property list. See the Data Members at the beginning of Animatable for details on aprops.

int PathPosition::SetProperty(ULONG id, void *data)
   {
   if (id==PROPID_JOINTPARAMS) {    
      if (!data) {
         int index = aprops.FindProperty(id);
         if (index>=0) {
            aprops.Delete(index,1);
            }
      } else {
         JointParamsPath *jp = (JointParamsPath*)GetProperty(id);
         if (jp) {
            *jp = *((JointParamsPath*)data);
            delete (JointParamsPath*)data;
         } else {
            aprops.Append(1,(AnimProperty**)&data);
            }              
         }
      return 1;
   } else
   if (id==PROPID_INTERPUI) {    
      if (!data) {
         int index = aprops.FindProperty(id);
         if (index>=0) {
            aprops.Delete(index,1);
            }
      } else {
         InterpCtrlUI *ui = (InterpCtrlUI*)GetProperty(id);
         if (ui) {
            *ui = *((InterpCtrlUI*)data);
         } else {
            aprops.Append(1,(AnimProperty**)&data);
            }              
         }
      return 1;
   } else {
      return Animatable::SetProperty(id,data);
      }
   }

Reimplemented in ShapeObject, and MtlBase.

virtual CoreExport void* GetProperty ( ULONG  id )

virtual

Remarks

This method is used to retrieve a property specified by the id passed (as stored by SetProperty()).

Note for 3ds Max version 1.1:

Two new property IDs have been added:

PROPID_CLEARCACHES: When passed to a texture map or material, the material should dump any of its caches. For example, the bitmap texture responds to this by freeing the bitmap from memory. For sample code see /MAXSDK/SAMPLES/MATERIALS/BMTEX.CPP.

PROPID_HAS_WSM: When passed to an INode, will return TRUE if the node has World Space Modifiers applied to it or FALSE if it does not. For sample code see /MAXSDK/SAMPLES/IMPEXP/3DSEXP.CPP.

Note for 3ds Max version 1.2:

A new id has been created and assigned the constant:

#define PROPID_EVAL_STEPSIZE_BUG_FIXED 0x1000.

This only effects the evaluation of objects when rendering them using motion blur. Motion blur works by evaluating the object numerous times (at fractions of a frame apart) and combining these images by blending them together.

Originally, 3ds Max would make these evaluations in reverse order within a sub-frame – from the last one, to the second to the last one, back to the first one. There is a problem with this for certain plug-ins that need to compute their state from time 0 forward. For these objects, the backwards approach may be too computationally intensive.

Both the forward and backward approaches exist in 3ds Max and the developer may choose which method to use. 3ds Max interrogates the object to see how it should handle the evaluation process – either going backwards or forwards. It calls this method with id set to the constant PROPID_EVAL_STEPSIZE_BUG_FIXED. If a plug-in implements this method to return nonzero, it means the plug-in works correctly using forward stepping, and 3ds Max will use that approach. If a plug-in does not implement this method and handle the id of PROPID_EVAL_STEPSIZE_BUG_FIXED it will return the default value of zero. This means the older method of backwards evaluation will be used.

Therefore, a plug-in object that wants to handle motion blur using forward stepping should implement this method, and if passed an id of PROPID_EVAL_STEPSIZE_BUG_FIXED, should return nonzero.

Parameters

id	The id of the property to retrieve.

Default Implementation:

{ return NULL; }

Sample Code:

This code is from /MAXSDK/SAMPLES/CONTROLLERS/PATHCTRL.CPP. It is used to restore the inverse kinematics user interface parameters of the path controller. It retrieves the property data on the aprops property list. See the Data Members at the beginning of Animatable for details on aprops.

CoreExport void AppendProperty

(

AnimProperty *

prop

)

A function to directly add arbitrary properties to this object developers should ensure that the properties ID does not conflict with any Max-specific IDs.

Parameters

prop	The new property to add

CoreExport AnimProperty* FindProperty

(

DWORD

id

)

Find any property.

This allows developers to add arbitrary properties to Animatables.

Parameters

id	the id of the property to find

Returns

the property if found, else null.

virtual int NumSubs ( )

inlinevirtual

Remarks

The system uses a virtual array mechanism to access the sub-anims of a plug-in. This method returns the total number of sub-anims maintained by the plug-in. If a plug-in is using a parameter block to manage its parameters it should just return 1 for all the parameters directed by the parameter block.

Returns

The number of sub-anims used by the plug-in.

Default Implementation:

{ return 0; }

Reimplemented in ShapeObject, Control, SimpleManipulator, PatchObject, MultCurveList, SimpleParticle, SplineShape, GizmoClass, EaseCurveList, SimpleOSMToWSMObject, SimpleWSMMod, SimpleWSMObject, UnifiedRenderer, SimpleSpline, SimpleShape, MSCustAttrib, MtlBaseLib, SimpleMod, SimpleObject, SimplePolyObject, MtlLib, GizmoObject, and PFSimpleAction.

{ return 0; }     

virtual Animatable* SubAnim ( int  i )

inlinevirtual

Remarks

This method returns a pointer to the 'i-th' sub-anim. If a plug-in is using a parameter block to manage all its parameters it should just return a pointer to the parameter block itself from this method. This method may return NULL so developers need to check the return value before calling other sub anim methods (such as SubAnimName()).

Parameters

i	This is the index of the sub-anim to return.

Default Implementation:

{ return NULL };

Reimplemented in ShapeObject, Control, SimpleManipulator, PatchObject, MultCurveList, SimpleParticle, SplineShape, GizmoClass, SimpleWSMMod2, EaseCurveList, SimpleOSMToWSMObject, SimpleWSMMod, SimpleMod2, SimpleWSMObject, UnifiedRenderer, SimpleSpline, SimpleShape, MSCustAttrib, MtlBaseLib, SimpleMod, SimpleObject, SimplePolyObject, MtlLib, GizmoObject, and PFSimpleAction.

{ return NULL; }  

virtual CoreExport MSTR SubAnimName ( int  i )

virtual

Remarks

This method returns the name of the 'i-th' sub-anim to appear in track view. The system has no idea what name to assign to the sub-anim (it only knows it by the virtual array index), so this method is called to retrieve the name to display. Developer need to make sure the 'i-th' SubAnim() is non-NULL or this method will fail.

Parameters

i	The index of the parameter name to return

Returns

The name of the 'i-th' parameter.

Reimplemented in ShapeObject, Control, SimpleManipulator, PatchObject, MultCurveList, SimpleParticle, SplineShape, GizmoClass, EaseCurveList, SimpleOSMToWSMObject, SimpleWSMMod, SimpleWSMObject, UnifiedRenderer, SimpleSpline, SimpleShape, MSCustAttrib, MtlBaseLib, SimpleMod, SimpleObject, SimplePolyObject, MtlLib, GizmoObject, and PFSimpleAction.

virtual BOOL BypassTreeView ( )

inlinevirtual

Remarks

This method indicates to the system that this anim should not appear in the Track View. Note: Track View was formally referred to as Tree View. This is what parameter blocks do for example. They don't show up in track view, just their sub-anims do. This prevents the extra level of the parameter block from appearing.

Returns

Return TRUE to not appear in the Track View. Note that if you return TRUE your children will appear in the track view regardless.

Default Implementation:

{ return FALSE; }

Reimplemented in MultCurveList, EaseCurveList, and LinearShape.

{ return FALSE; } 

virtual BOOL BypassTrackBar ( )

inlinevirtual

Remarks

This method indicates to the system that this anim should not appear in the Track Bar. The anim won't show up in the Track Bar, just its sub-anims will. This function is similar to BypassTreeView(), but refers to the Track Bar instead of the Track View.

Returns

Return TRUE to not appear in the Track Bar. Note that if you return TRUE your children will appear in the Track Bar regardless.

Default Implementation:

{ return BypassTreeView(); }

{ return BypassTreeView(); } 

virtual BOOL BypassPropertyLevel ( )

inlinevirtual

Remarks

Use this method in order to cause parameters in this Animatable (as a sub-anim) to appear to reside at the level of the parent Animatable in the scripter. Return TRUE and this Animatable won't appear as a property in the scripter however it's sub-anims children will. The default implementation returns FALSE indicating it will appear normally.

Default Implementation:

{ return FALSE; }

Reimplemented in BaseShader, and ShadowType.

{ return FALSE; } 

virtual BOOL InvisibleProperty ( )

inlinevirtual

Remarks

This method controls the visibility of this Animatable and all of it sub-anims to appear as properties in the scripter. Return TRUE and it won't nor will it's sub-anims. Returning FALSE (the default implementation) causes this Animatable and it's sub-anims to appear as normal.

Default Implementation:

{ return FALSE; }

{ return FALSE; } 

virtual BOOL AssignController ( Animatable *  control, int  subAnim  )

inlinevirtual

Remarks

This method is called to assign the controller to the sub-anim whose index is passed.

Parameters

control	The controller to assign.
subAnim	The index of the sub-anim to assign the controller to.

Default Implementation:

{ return FALSE; }

Returns

Returns TRUE if the controller was assigned; otherwise FALSE.

Reimplemented in PatchObject, MultCurveList, SplineShape, EaseCurveList, and SimpleMod.

{ return FALSE; }

virtual BOOL CanAssignController ( int  subAnim )

inlinevirtual

Return true if we can reassign the subanim specified.

Implement this function to return false if we wish to prevent any subanim from being replaced. If this method returns false for any id, that subanim will not be able to be re-assigned via the UI or MaxScript controls. Note that this will not prevent re-assigning in C++ in any way (via the ReplaceReference or AssignController functions).

Parameters

subAnim

- The ID of the SubAnim to check.

Returns

TRUE if it is legal to assign a new Animatable to the specified SubAnim

{ return TRUE; }

virtual BOOL CanDeleteSubAnim ( int  i )

inlinevirtual

Remarks

Returns TRUE if the specified sub-anim controller can be deleted; otherwise FALSE.

A new "Delete Controller" button has been added to the Track View toolbar that is enabled when one or more delete-able tracks are selected. This method allows a plug-in to indicate to the Track View that one or more of its sub-controllers are delete-able. This provides a way to allow the user to delete node sub-controllers such as the visibility track, "Image Motion Blur Multiplier", "Object Motion Blur On/Off", etc. If the user selects one of the above-mentioned tracks in the Track View the "Delete Controller" button will become available.

Parameters

i	The zero based index of the sub-anim.

Default Implementation:

{return FALSE;}

Reimplemented in PFSimpleAction.

{ return FALSE; }

virtual void DeleteSubAnim ( int  i )

inlinevirtual

Remarks

This method is called to delete the specified sub-anim controller. See the remarks in CanDeleteSubAnim() above.

Parameters

i	The zero based index of the sub-anim.

Default Implementation:

{}

{}

virtual DWORD GetSubAnimCurveColor ( int  subNum )

inlinevirtual

Remarks

Return the suggested color to draw a sub-anim's function curve. For example, the independent X, Y, Z position controller implements this method to return the suggested color for each of it's sub-controllers. The Euler Angle Controller uses these so its 3 sub-controllers are drawn in different colors.

Parameters

subNum

The index of the sub-anim.

Returns

One of the following values:

PAINTCURVE_GENCOLOR

PAINTCURVE_XCOLOR

PAINTCURVE_YCOLOR

PAINTCURVE_ZCOLOR

Default Implementation:

{return PAINTCURVE_GENCOLOR;}

{ return PAINTCURVE_GENCOLOR; }

virtual int SubNumToRefNum ( int  subNum )

inlinevirtual

Remarks

This method is used for copying and pasting in the track view. It converts an anim index to a reference index or returns -1 if there is no correspondence. If a client does not wish an anim to be copied or pasted then it can return -1 even if there is a corresponding reference num.

Parameters

subNum

The anim index to return the corresponding reference index of.

Default Implementation:

{ return -1}

Returns

The reference index corresponding to the anim index passed. Return -1 if there is no correspondence.

Reimplemented in PatchObject, MultCurveList, SplineShape, GizmoClass, EaseCurveList, SimpleMod, and PFSimpleAction.

virtual int GetKeyTimes ( Tab< TimeValue > &  times, Interval  range, DWORD  flags  )

inlinevirtual

Remarks

This method is called to build a table of time values, one time for each key within the interval passed. The plug-in should load up the table passed with the time of each key present over the specified time range.

Parameters

times	The table of time values to build. See Class Tab.
range	The range of time over which to retrieve the key times. See Class Interval.
flags	One of the following values: KEYAT_POSITION Return for Position keys only. KEYAT_ROTATION Return for Rotation keys only. KEYAT_SCALE Return for Scale keys only.

Returns

The plug-in should return an offset so the system can access the keys using an index. Thus it should return the number of keys skipped because their times were before range.Start(). For example, say the first keyframe in the interval passed was actually the third key overall. The plug-in should return 2 (two keys preceded the first one stored). In this way, the system can access the key as the i-th key in the table plus 2.

Default Implementation:

{return 0;}

{ return 0; }       

virtual int GetKeySelState ( BitArray &  sel, Interval  range, DWORD  flags  )

inlinevirtual

Remarks

When this method is called, the plug-in should update the BitArray sel to indicate if its keys present in the interval passed are selected or deselected.

Parameters

sel	The bit array to update, one bit for each key within the interval range. If the key is selected, the corresponding bit should be 1, otherwise it should be 0. See Class BitArray.
range	The range of time over which to retrieve the key selected state. See Class Interval.
flags	One or more of the following values: KEYAT_POSITION Return for Position keys only. KEYAT_ROTATION Return for Rotation keys only. KEYAT_SCALE Return for Scale keys only.

Note

If the flags are passed as 0, use ALL keys within the range.

Returns

The number of keys skipped because their times were before range.Start().

Default Implementation:

{return 0;}

{ return 0; }

TIMERANGE_CHILDNODES The node's time range should include its child nodes. TIMERANGE_CHILDANIMS A animatable's child anim ranges should be included.

Returns

An interval representing the tracks time range.

Reimplemented in DefNoteTrack.

virtual void EditTimeRange ( Interval  range, DWORD  flags  )

inlinevirtual

Remarks

This method is called to change the range of the anim (usually a controller) to the given range. This is the range that is used to compute the Out of Range Types. For example, this method may be called when the user is working in Position Range mode in the Track View.

Keyframe controllers generally support this method. Other controllers may or may not support this method. For example, a procedural controller may want to maintain a range upon which the animation is based. The user may then move the range bar around to move the procedural animation around.

The range passed is the range used to compute the Out of Range Types. This may be used for example with the Loop ORT to extend the range, either past the last key or before the first key, so there is some time to loop back to the start.

The 3ds Max keyframe controllers maintain an interval that is their range. It is normally defined to be the first key to the last key. If the user goes into Position Range mode and moves the range around, this method is called. The keyframe controllers set a flag to indicate that the range is no longer linked to the first key or the last key. Then the range is stored in the interval, and this is considered the 'in range' portion of the controller. If time is evaluated outside of this range it applies the ORTs to determine the value.

Parameters

range	The new range for the anim.
flags	EDITRANGE_LINKTOKEYS If this flag is set, the controller should re-establish the link between the start and end keys and its range. This is passed if the user presses the link to keys button in Track View. Thus, if one of the ends of the interval is at a key, link it to the key so that if the key moves, the interval moves.

Default Implementation:

{}

{};

virtual void DeleteTime ( Interval  iv, DWORD  flags  )

inlinevirtual

Remarks

This method is called to delete the specified interval of time (or the keys within the interval).

Parameters

iv	The interval of time to delete.

Default Implementation:

{}

Reimplemented in DefNoteTrack.

{}

virtual void ReverseTime ( Interval  iv, DWORD  flags  )

inlinevirtual

Remarks

This method is called to reverse the data within the specified interval. For example, if the interval passed is from frame 10 to 20, and there is a key at frame 12, the key should be moved to frame 18. Considered another way, if all the times were normalized, and there was a value n between 0 and 1, n should be changed to 1-n.

Parameters

iv	The interval of time over which to reverse the data.
flags	One or more of the following values: TIME_INCLEFT Include the left endpoint. TIME_INCRIGHT Include the right endpoint.

Default Implementation:

{}

{ return FALSE; }

virtual void FlagKey ( TrackHitRecord  hit )

inlinevirtual

Remarks

This method is called to have the plug-in flag or mark a specific key identified by the TrackHitRecord.

As an example, when the user goes to move a selection set of keys in the Track View, a yellow marker is drawn. To move the group of keys, the user clicks on a single one. The system needs to track this one key as it is moved, and needs a way to identify it. This method is called so the developer can flag this key as the one that was selected. This is needed because the Track View doesn't know anything about a specific controllers ordering of keys and thus cannot refer to it by index.

The system will call GetFlagKeyIndex() (described below) to retrieve the index of the key that was flagged.

Parameters

hit	The hit record that the controller gave the Track View in the first place to identify the hit. Thus this is enough information to identify the key. See Class TrackHitRecord.

Default Implementation:

{}

Sample Code:

template <class KT>
void GenMorphCont<KT>::FlagKey(TrackHitRecord hit)
   {
   int n = keys.Count();
   for ( int i = 0; i < n; i++ ) {
      keys[i].ClearFlag(KEY_FLAGGED);
      }
   assert(hit.hit>=0&&hit.hit<(DWORD)n);
   keys[hit.hit].SetFlag(KEY_FLAGGED);
   }

virtual int GetFlagKeyIndex ( )

inlinevirtual

Remarks

Returns the index of the key that is flagged, or -1 if no keys are flagged. See the method above.

Default Implementation:

int GenMorphCont<KT>::GetFlagKeyIndex()
   {
   int n = keys.Count();
   for ( int i = 0; i < n; i++ ) {
      if (keys[i].TestFlag(KEY_FLAGGED)) {

virtual void AddNewKey ( TimeValue  t, DWORD  flags  )

inlinevirtual

Remarks

This method is called to add a new key at the specified time. The value of the key is set to the value of the previous key, or interpolated between keys, based on the flags passed.

Parameters

t	The time to add the key.
flags	One or more of the following values: ADDKEY_SELECT Select the new key and deselect any other selected keys. ADDKEY_INTERP If TRUE then initialize the new key to the interpolated value at that time. If FALSE, initialize the key to the value of the previous key.

Default Implementation:

{}

Reimplemented in DefNoteTrack.

virtual void MoveKeys ( ParamDimensionBase *  dim, float  delta, DWORD  flags  )

inlinevirtual

Remarks

This method is called to move selected keys vertically in the function curve editor. This moves the key values but does not alter the key times. The developer adds the delta to the selected key values, after converting them using the dimension *dim passed. See the sample code below for how this may be done.

Parameters

dim	Used to scale the parameter's values into and out of units used in the user interface. For example, if the parameter was an angle, it would be shown in degrees, but stored in radians. Methods of this class allow the value to be converted back and forth. This is needed because the delta passed is in user interface units. Thus the selected key values need to be converted before the delta is applied. See Class ParamDimensBase.
delta	The amount to move the keys (move the values - not the times). This is in the units of the user interface. For example, if an angle has a value in the function curve editor of 100 degrees, 100 would be passed as the delta.
flags	Not currently used.

Default Implementation:

{}

Sample Code:

void BoolCntrl::MoveKeys(ParamDimensionBase *dim,float delta,DWORD flags)
{

    int n = (int) keys.length(); // downcast to 2 Gigs
    if (!n||GetLocked()==true) return;
    float m = 1.0f;
    Interval valid;
    BOOL changed = FALSE;
    RevertSetKeyBuffer(TRUE);
    HoldTrack();
    for (int i = 0; i < n; i++ ) {
        if (keys[i].AnyElemSelected()) {
            m = GetMultVal(keys[i].time,valid); 
        }
        if (keys[i].ElemSelected(0)) {
            keys[i][0] = dim->UnConvert(dim->Convert(keys[i][0]*m)+delta)/m;
            changed = TRUE;
            if (keys[i][0] > 0.0) {
                if (delta < 0.0){
                    keys[i][0] = 0.0;
                }
                else
                    keys[i][0] = 1.0;
            }
            else if (keys[i][0] <= 0.0) {
                if (delta > 0.0){
                    keys[i][0] = 1.0;
                }
                else

            }
        }

    }
}

{}  

virtual void ScaleKeyValues ( ParamDimensionBase *  dim, float  origin, float  scale, DWORD  flags  )

inlinevirtual

Remarks

This method is called to scale selected keys values. This scales the key values but does not alter the key times. The developer scales the selected key values about the specified origin, after converting them using the dimension *dim passed.

Note the following macro available for scaling about an origin:

#define ScaleAboutOrigin(val,origin,scale)

((((val)-(origin))*(scale))+(origin))

Parameters

dim	Used to scale the parameter's values into and out of units used in the user interface. For example, if the parameter was an angle, it would be shown in degrees, but stored in radians. Methods of this class allow the value to be converted back and forth. See Class ParamDimensBase.
origin	The origin about which the keys are scaled.
scale	The scale factor to apply to the key values.
flags	Not currently used.

Default Implementation:

{}

Sample Code:

INTERP_CONT_TEMPLATE
void InterpControl<INTERP_CONT_PARAMS>::ScaleKeyValues(ParamDimensionBase *dim,float origin,float scale,DWORD flags)

subNum

The index of the sub-anim

Returns

TRUE if subNum is seletected.

{ return FALSE; }

virtual int GetSelKeyCoords ( TimeValue &  t, float &  val, DWORD  flags  )

inlinevirtual

Remarks

This method is used to determine the commonality of the selected keys for display in the time/value type in fields of Track View. It is also used to retrieve the value and/or time of the selected keys (if there is only one selected, or they are common to the selected keys). The flags parameter specified which values to retrieve. The return value indicates if nothing, or several keys were selected. It also indicates if the selected keys shared a common time and/or common value.

Parameters

t	The time of the selected keys is returned here (if appropriate).
val	The value of the selected keys is returned here (if appropriate).
flags	One of the following values: KEYCOORDS_TIMEONLY Only the time t needs to be updated. KEYCOORDS_VALUEONLY Only the value val needs to be updated.

Returns

This indicates what was selected, and what these keys had in common. One or more of the following values should be set:

KEYS_NONESELECTED
This indicates that no keys are selected.

KEYS_MULTISELECTED
This indicates that multiple keys are selected. Both of these last two bits could be set.

KEYS_COMMONTIME
If the selected keys share the same time then this flag should be set. In this case it is appropriate to update t if required.

KEYS_COMMONVALUE
If the selected keys share the same value then this flag should be set. In this case it is appropriate to update val if required.

Default Implementation:

{return KEYS_NONESELECTED;}

Reimplemented in DefNoteTrack.

                                                                           {

        }

virtual void SetSelKeyCoords ( TimeValue  t, float  val, DWORD  flags  )

inlinevirtual

Remarks

This method is called to update the time and/or value of the selected keys as specified by the flags. This is called if the user uses the time/value type in fields of Track View.

Parameters

t	The time to set for the selected keys (if the flags indicate this is needed).
val	The value to set for the selected keys (if the flags indicate this is needed).
flags	One of the following values: KEYCOORDS_TIMEONLY Only the time needs to be updated. KEYCOORDS_VALUEONLY Only the value needs to be updated.

Default Implementation:

{}

Reimplemented in DefNoteTrack.

{}

virtual int SetSelKeyCoordsExpr ( ParamDimension *  dim, const MCHAR *  timeExpr, const MCHAR *  valExpr, DWORD  flags  )

inlinevirtual

Remarks

This method is similar to SetSelKeyCoords() above. In that case you're given a time and a value and are to update the selected keys with these values (based on the flags passed). In this case, you are instead passed time and value expressions (as strings). The ideas is that these strings are evaulated as expressions and the resulting values are used to updated the selected keys. For instance, the user could select a bunch of keys and then type in n+45. This would add 45 to all the values of the keys.

Developers can use the 3ds Max expression parser (see Class Expr) to evaluate the strings. Debug SDK users can see /MAXSDKDB/SDKSRC/CTRLTEMP.H for an example (or see the sample code below)). If a plug-in doesn't support this feature it can return FALSE from this method and the old SetSelKeyCoords() method will be called. Note that the variable names are defined as KEYCOORDS_TIMEVAR and KEYCOORDS_VALVAR.

Parameters

dim	This is used to convert the parameter value once you get it.
timeExpr	A string containing the time expression.
valExpr	A string containing the value expression.
flags	One of the following values: KEYCOORDS_TIMEONLY Only the time t needs to be updated. KEYCOORDS_VALUEONLY Only the value val needs to be updated.

Returns

This indicates what was selected, and what these keys had in common. One or more of the following values should be set:

KEYCOORDS_EXPR_UNSUPPORTED
Don't implement this method

KEYCOORDS_EXPR_ERROR
Error in expression

KEYCOORDS_EXPR_OK
Expression evaluated

Default Implementation:

{return KEYCOORDS_EXPR_UNSUPPORTED;}

Sample Code:

    ParamDimension *dim,
    const TCHAR *timeExpr, const TCHAR *valExpr, DWORD flags)

See also

SetKeyBufferPresent

Parameters

subNum

- The index of the SubAnim to test.

Returns

TRUE if the SubAnim has a SetKey buffer present

Default Implementation:

    if (SubAnim(SubNum)) return SubAnim(subNum)->SetKeyBufferPresent();
    return FALSE;
}

virtual BOOL SetKeyBufferPresent ( )

inlinevirtual

returns true if there is a "Set Key" buffer present

This method should be implemented for a keyframeable controller to support the "Set Key" animation mode. When in the "Set Key" mode, if the user modifies a keyframe controller the controller should create a temporary buffer to hold the new value until the user either commits or cancels the change.

Note

It is the plugins responsibility to ensure that the correct value (either the temp buffer or the permanent keyframed value) is returned from GetValue. For an example implementation of this method, look at samples/controllers/boolctrl.cpp

Returns

True if a buffer is present

{ return FALSE; }

}

virtual void CommitSetKeyBuffer ( TimeValue  t )

inlinevirtual

Commit any "Set Key" buffers.

This function will be called whenever the user clicks the the large "Set Keys" button. If this animatable is keyable, it should commit any temporary "Set Key" buffers to its permanent keyframe storage. For an example implementation of this method, look at samples/controllers/boolctrl.cpp

virtual BOOL CanCopySubTrack ( int  subNum, Interval  iv, DWORD  flags  )

inlinevirtual

Remarks

This method is available in release 2.0 and later only.

If CanCopyTrack() returns FALSE then this method is called on the sub-anim (passing the sub number).

This is used in particular for Parameter Blocks. In that case, if there is no controller plugged into the track, the copying and pasting of controllers can't be done (since there is no controller). However, this method allows the Parameter Block to handle it.

Parameters

subNum	Specifies the sub-anim to check.
iv	The interval of time over which to copy the track data.
flags	One or more of the following values: TIME_INCLEFT Include the left endpoint. TIME_INCRIGHT Include the right endpoint.

Returns

TRUE if the specified item can copy its data over the specified range; otherwise FALSE.

Default Implementation:

{return FALSE;}

{ return FALSE; }

virtual BOOL CanPasteSubTrack ( int  subNum, TrackClipObject *  cobj, Interval  iv, DWORD  flags  )

inlinevirtual

Remarks

This method is available in release 2.0 and later only.

Returns TRUE if the specified item can paste its data over the specified range; otherwise returns FALSE.

Plug-ins can implement pasting for cases where their sub-anims don't implement it. An example of this is the Parameter Block class. It implements this method to allow pasting parameters that don't have controllers assigned to them. These aren't called on the client unless the sub-anim doesn't implement CanPasteTrack().

Parameters

subNum	Specifies the sub-anim to check.
cobj	The data to paste.
iv	The interval of time to paste.
flags	One or more of the following values: TIME_INCLEFT Include the left endpoint. TIME_INCRIGHT Include the right endpoint.

virtual int GetTrackVSpace ( int  lineHeight )

inlinevirtual

Remarks

Returns the vertical space occupied by the track in units of one line.

Parameters

lineHeight

The height of a single line in pixels.

Default Implementation:

{ return 1; }

Reimplemented in DefNoteTrack.

{ return 1; }

virtual int HitTestTrack ( TrackHitTab &  hits, Rect &  rcHit, Rect &  rcTrack, float  zoom, int  scroll, DWORD  flags  )

inlinevirtual

Remarks

This method is called to determine which keys lie within the rcHit rectangle. Keys that are hit are added to the hits table.

Parameters

hits	The table of TrackHitRecords to update. Each key that lies within the hit rectangle (is hit) should be added to this table. It is up to the plug-in to define a scheme that allows it to identify its hits using the data members of Class TrackHitRecord. Also see Class Tab for methods to add to the table.
rcHit	This is the region that was selected for hit testing. This may be a small rectangle about the mouse pick point, or a larger rectangle if the user selected by window.
rcTrack	This is the entire rectangular region of the track.
zoom	The is the time zoom factor.
scroll	This is the time scroll factor.
flags	One or more of the following value: HITTRACK_SELONLY Selected only. HITTRACK_UNSELONLY Unselected only. HITTRACK_ABORTONHIT Abort hit testing on first hit. HITCURVE_TESTTANGENTS Hit test curve tangents.

Returns

One of the following values:

TRACK_DONE
This indicates the track was hit tested.

TRACK_DORANGE
This indicates that the system will handle hit testing to the range bar for the item. For example a node returns this value because it does not have any keys. Therefore it just lets the user hit test the range bar. In general, anything that is not a leaf controller will not implement this method and return the default. The system will then simply hit test the range bar.

TRACK_ASKCLIENT
If a plug-in returns this value then the anim's client will be given a chance to paint the track in Track View. If a client returns this value then the method PaintSubTrack() will be called.

Default Implementation:

{ return TRACK_DORANGE; }

Reimplemented in DefNoteTrack.

                          { return TRACK_DORANGE; }

virtual int PaintTrack ( ParamDimensionBase *  dim, HDC  hdc, Rect &  rcTrack, Rect &  rcPaint, float  zoom, int  scroll, DWORD  flags  )

inlinevirtual

Remarks

This method is called to display the item in the track view. If an item needs to draw itself in a special fashion, it implements this method to do so. For example, a sound plug-in may draw its waveform using this method. If an item does not need to draw itself, the default implementation may be used. This draws the range bar for the item.

Note: When drawing something to appear in Track View, a developer should not do any clipping of their own. 3ds Max will take care of all clipping itself.

Parameters

dim	The dimension for the parameter of this track.
hdc	The handle of the device context.
rcTrack	The entire rectangle of the inside of the track.
rcPaint	This is the rectangular region that needs to be repainted - the invalid region.
zoom	The time zoom factor.
scroll	The time scroll factor.
flags	One or more of the following values which are filters for controllers with more than one curve: DISPLAY_XCURVE DISPLAY_YCURVE

Note

RGB controllers interpret X as red, Y as green, and Z as blue. DISPLAY_ZCURVE

Returns

One of the following values:

TRACK_DONE
Indicates the track was painted.

TRACK_DORANGE
Indicates the system should draw the range bars for the item.

TRACK_ASKCLIENT
Indicates the anim's client will be given a chance to paint the track in Track View. See Animatable::PaintSubTrack() which will be called to do this.

Default Implementation:

{ return TRACK_DORANGE; }

Reimplemented in DefNoteTrack.

                          { return TRACK_DORANGE; }

virtual void EditTrackParams ( TimeValue  t, ParamDimensionBase *  dim, const MCHAR *  pname, HWND  hParent, IObjParam *  ip, DWORD  flags  )

inlinevirtual

Remarks

This method is called for the plug-in to put up a modal dialog and let the user edit the tracks parameters for the selected keys. This function should not return until the user has completed editing at which time any windows that were created should be destroyed. Unlike BeginEditParams() and EndEditParams() this interface is modal.

Returns

One of the following values:

TRACKPARAMS_NONE

Has no track parameters. If this is returned then EditTrackParams() will not be called.

TRACKPARAMS_KEY

Entered by right clicking on a selected key. This should be used if the dialog provides parameters for the entire controller (for example as the Noise controller's dialog does).

TRACKPARAMS_WHOLE

Entered by right clicking anywhere in the track. This should be used if the dialog will represent the selection of keys (as a key info type dialog does).

Default Implementation:

{return TRACKPARAMS_NONE;}

Reimplemented in DefNoteTrack.

{return TRACKPARAMS_NONE;}

virtual int GetFCurveExtents ( ParamDimensionBase *  dim, float &  min, float &  max, DWORD  flags  )

inlinevirtual

This method is called to calculate the largest and smallest values of the anim.

The values max and min should be initialized before calling this function. A plugin implementing this function should not reset the values passed - in this way if max is passed with a larger value than the curve extents calculated for the current anim, the value of max will be unchanged.

Parameters

	dim	- The dimension of the anim.
[out]	min	- The smallest value. These are in the units given by the dimension. For example, if it was an angle parameter that was displayed in degrees, the units returned through min should be in degrees as well. A class should implement this method to not reset this value
[out]	max	- The largest value. These are in the units given by the dimension. For example, if it was an angle parameter that was displayed in degrees, the units returned through max should be in degrees as well.
	flags	- One or more of the following values which are filters for controllers with more than one curve: DISPLAY_XCURVE DISPLAY_YCURVE DISPLAY_ZCURVE

Note

RGB controllers interpret X as red, Y as green and Z as blue.

Returns

If this method is processed, return nonzero; otherwise zero.

Reimplemented in Control.

                         { return 0; }

virtual int GetSubFCurveExtents ( int  subNum, ParamDimensionBase *  dim, float &  min, float &  max, DWORD  flags  )

inlinevirtual

The values max and min should be initialized before calling this function.

Parameters

	subNum	- The index of the SubAnim to query for curve extents
	dim	- The dimension of the anim.
[out]	min	- The smallest value. These are in the units given by the dimension. For example, if it was an angle parameter that was displayed in degrees, the units returned through min should be in degrees as well. A class should implement this method to not reset this value
[out]	max	- The largest value. These are in the units given by the dimension. For example, if it was an angle parameter that was displayed in degrees, the units returned through max should be in degrees as well.
	flags	- One or more of the following values which are filters for controllers with more than one curve: DISPLAY_XCURVE DISPLAY_YCURVE DISPLAY_ZCURVE

Note

RGB controllers interpret X as red, Y as green and Z as blue.

virtual CoreExport void EnumAuxFiles ( AssetEnumCallback &  assetEnum, DWORD  flags = FILE_ENUM_ALL  )

virtual

Remarks

This method is used to enumerate any 'auxiliary' files maintained by the item and record the filename with the callback. Entities which actually need to load auxiliary files (for instance texture maps) must implement this method, possibly calling ReferenceMaker::EnumAuxFiles() also. The ReferenceMaker implementation simply calls itself on all its references (see below).

Class Interface has a method that may be used to call this on the entire system. This includes the renderer, materials editor, atmospheric effects, background, video post, lights, etc. – everything that may have auxiliary files associated with it. After specifying the appropriate flags a list of filenames is created that matched the enumeration conditions as specified by the flags. This is used for instance by the Archive function in 3ds Max to grab a list of bitmap files used by the system.

Parameters

assetEnum	The callback object that may be used to record the asset. See Class AssetEnumCallback.
flags	See Auxilliary File Enumeration Flags

Sample Code:

void MaxShader::EnumAuxFiles(AssetEnumCallback& assetEnum, DWORD flags) 
{
    if ((flags & FILE_ENUM_CHECK_AWORK1) && TestAFlag(A_WORK1))
        return; 
    if (!(flags & FILE_ENUM_INACTIVE))
        return; // not needed by renderer

    PBBitmap* bm = NULL;
    for(int i=0; i < CHANNEL_MAX; i++)
    {
        ParamID pid = DIFFUSE_FILE + i;
        if (m_PBlock->GetParamDef(pid).type == TYPE_BITMAP)
        {
            ParamID pid = m_PBlock->IndextoID(i);
            m_PBlock->GetValue(pid,0,bm,FOREVER);
            if(bm)
            {
                if(flags & FILE_ENUM_ACCESSOR_INTERFACE)
                {
                    IEnumAuxAssetsCallback* callback = static_cast<IEnumAuxAssetsCallback*>(&assetEnum);
                    callback->DeclareAsset(MaxShaderAccessor(m_PBlock, DIFFUSE_FILE + i));
                }
                else
                {
                    bm->bi.EnumAuxFiles(assetEnum,flags);
                }  
            }
        }
    }
    ReferenceTarget::EnumAuxFiles( assetEnum, flags );
}

Reimplemented in ReferenceMaker, and MtlBase.

virtual void FreeAllBitmaps ( )

inlinevirtual

Remarks

This method is available in release 2.0 and later only.

This method frees all bitmaps in this Animatable but doesn't recurse. This is used for freeing all the scene bitmaps after a render.

Default Implementation:

{}

{}

virtual void GetSystemNodes ( INodeTab &  nodes, SysNodeContext  Context  )

inlinevirtual

Remarks

The master controller of a system plug-in should implement this method to give 3ds Max a list of nodes that are part of the system. The master controller should fill in the given table with the INode pointers of the nodes that are part of the system. This will ensure that operations like cloning and deleting affect the whole system.

Said another way, GetSystemNodes() should be implemented for the master controller of a system, and should return a list of pointers to all nodes that are part of the system. GetInterface() should be implemented for the slave TM controllers of the system and return a pointer to the master controller.

3ds Max will use GetInterface() in the TM controller of each selected node to retrieve the master controller and then call GetSystemNodes() on the master controller to get the list of nodes.

Parameters

nodes	The table of nodes that are part of the system.
Context	This parameter is available in release 4.0 and later only. This parameter can be used to specify the context under which the "system nodes" are used. These are; kSNCClone, kSNCDelete, kSNCFileMerge, and kSNCFileSave.

Default Implementation:

{}

{}

virtual BOOL IsSubClassOf ( Class_ID  classID )

inlinevirtual

returns true if the animatable has sub-classed off the given class

If an object is a sub-class of a particular class, it will have a different ClassID() because it is a different class. This method allows an object to indicate that it is a sub-class of a particular class and therefore can be treated as one. For example, a class could be derived from TriObject. This derived class would have a different ClassID() then the TriObject's class ID however it still can be treated (cast) as a TriObject because it is derived from TriObject. Note the default implelementation: a class is considered to also be a subclass of itself.

Parameters

classID

The Class_ID of the item that this class is a sub-class of.

Returns

TRUE if this class is a sub-class of classID; otherwise FALSE.

Default Implementation:

{return classID==ClassID();}

Reimplemented in PatchObject.

                                                    {
            return (classID == ClassID());
        }

virtual BOOL IsRefMaker ( )

inlinevirtual

Tells whether it is a ReferenceMaker.

This function differentiates things sub classed from Animatable from subclasses of ReferenceMaker. The implementation of this method (in Animatable) returns FALSE and its implementation in ReferenceMaker returns TRUE.

Returns

Default of FALSE.

Reimplemented in ReferenceMaker.

{ return FALSE; }

CoreExport void AddAppDataChunk	(	const Class_ID &	cid,
		SClass_ID	sid,
		DWORD	sbid,
		DWORD	len,
		void *	data
	)

Adds application/plugin specific (custom) data to an Animatable.

This method is used to add an AppDataChunk to this Animatable. The chunk is identified using the Class_ID, and SuperClassID of the owner, and an ID for sub-chunks.

Note

Developers who want to add appdata to the scene should see the method Interface::GetScenePointer().

Parameters

cid	- The Class_ID of the owner of the chunk.
sid	- The SuperClassID of the owner of the chunk.
sbid	- An extra ID that lets the owner identify its sub-chunks.
len	- The length of the data in bytes.
data	- Pointer to the actual data. The data should be allocated on the heap by client code using MAX_malloc(). This will allow the system to free it safely (using MAX_free()). MAX_malloc() and MAX_free() are memory management routines implemented by the system.

Note

Not allocating on the heap the data passed to this method may lead to unexpected behaviour of the application.

Client code does not need to free the data that has been passed to this method. The system will free it when the Animatable is deleted or when client code explicitely removes the custom data chunk from the Animatable by calling Animatable::RemoveAppDataChunk.

CoreExport AppDataChunk* GetAppDataChunk	(	const Class_ID &	cid,
		SClass_ID	sid,
		DWORD	sbid
	)

Retrieves the application/plugin specific (custom) data stored with an Animatable.

This method is used to retrieve a pointer to an AppDataChunk. The chunk is identified using the Class_ID, SuperClassID and sub-chunk ID of the owner.

Parameters

cid	- The Class_ID of the owner of the chunk.
sid	- The SuperClassID of the owner of the chunk.
sbid	- An extra ID that lets the owner identify its sub-chunks.

Returns

A pointer to the previously stored AppDataChunk, or NULL if it could not be found.

See also

class AppDataChunk.

CoreExport BOOL RemoveAppDataChunk	(	const Class_ID &	cid,
		SClass_ID	sid,
		DWORD	sbid
	)

Deletes the application/plugin specific (custom) data stored with an Animatable.

This method is used to delete an AppDataChunk. The chunk is identified using the Class_ID, SuperClassID and sub-chunk ID of the owner.

Parameters

cid	- The Class_ID of the owner of the chunk.
sid	- The SuperClassID of the owner of the chunk.
sbid	- An extra ID that lets the owner identify its sub-chunks.

Returns

TRUE if the data was deleted, FALSE if it could not be found.

CoreExport void ClearAllAppData

(

)

Deletes all application/plugin specific (custom) data stored with an Animatable.

Calling this method will remove all the AppData associated with this Animatable.

Note

Plugins that call this method will erase all appdata chunks, not just their own. Therefore, it is usually more appropriate to call RemoveAppDataChunk() to remove custom application data associated with a specific Class_ID.

static CoreExport bool RegisterAppDataLoadCallback ( const Class_ID &  cid, SClass_ID  sid, APPDATALOADPROC  proc  )

static

Registers a callback proc that is called when an AppDataChunk is read from a scene file.

When an AppDataChunk with the specified SuperClassID and Class_ID is read from the scene file, the specified callback proc is called. This is to permit versioning of the AppDataChunk.

virtual CoreExport void MouseCycleCompleted ( TimeValue  t )

virtual

Remarks

This method is available in release 2.0 and later only (previously in Class Control in 1.x).

This method is called on whatever controller the user is modifying with the mouse – when the mouse button is released. For example when the user selects a node in the viewports, then drags, then releases the mouse button, this method is called. This method will also be called when the user clicks on a key in the track view and lets up. If a controller performs extensive calculation in its evaluation this method is handy. The controller could perhaps perform a simplified calculation during interactive adjustment of a node. Then when the user releases the mouse button this method is called and the extensive calculations are performed.

The default implementation of this method is recursive so it gets called on all sub-anims affected by a range bar operation.

Parameters

t	The time the mouse was released.

virtual CoreExport void MouseCycleStarted ( TimeValue  t )

virtual

Remarks

This method is called on whatever controller the user is modifying with the mouse – when the mouse button is pressed.

The default implementation of this method is recursive so it gets called on all sub-anims affected by a range bar operation.

Parameters

t	The time the mouse was first pressed.

Operators:

virtual CoreExport SvGraphNodeReference SvTraverseAnimGraph ( IGraphObjectManager *  gom, Animatable *  owner, int  id, DWORD  flags  )

virtual

Remarks

This method is available in release 3.0 and later only.

This method traverses the graph of objects in the 3ds Max scene, adding desired objects to the schematic view. Developers can specialize this behaviour by overriding this method and adding whatever objects are interesting to the schematic view. Objects are added to the schematic view by calling IGraphObjectManager::AddAnimatable(...). Reference lines are added to the schematic view by calling IGraphObjectManager::AddReference(...). Implementers of this method should call it recursively to process other objects in the scene.

See Class IGraphObjectManager.

Parameters

gom	Points to the schematic view window manager.
owner	The owning animatable.
id	This is usually the sub-anim number (but can actually be any value the developer chooses).

virtual bool IsParamBlockDesc2Used ( ParamBlockDesc2 *  desc )

inlinevirtual

Returns true if the passed description is being used.

When plugins use a dynamic Paramblock2 system, and build a ParamBlockDesc2 on demand, the list maintained by the ClassDesc may not reflect the active configuration in the plugin. This method lets the system filter the list maintained by asking the plugin (such as the DxMaterial) whether the current ParamBlockDesc2 is currently used by the plugin. Anybody querying the ClassDesc for the ParamBlockDesc2 needs to make sure that the descriptor is currently being used by the plugin.
This mostly goes for maxscript.

Parameters

desc	The description to test

Returns

true if the plugin is currently using a parameter block built from desc.

Default Implementation:

{
    return false;
}  

{ return true; }

virtual bool GetMacroRecorderName ( bool  used_as_rhs_value, MSTR &  objectSpecifiedName  )

inlinevirtual

This method is called to access the object specified name to use for the Maxscript macrorecorder.

The Maxscript macrorecorder will determine the name of the object to use when emitting code. In some cases it cannot determine a name for the object, for example when setting a value on a ParamBlock when the ParamBlock owner is a utility plugin singleton. This method allows the object to specify the name to be used. If this method returns true and objectSpecifiedName is empty, no code will be emitted. This is useful in the case where you don't changes to an object's parameters to be macro recorded.

Parameters

used_as_rhs_value	[in] The object is being assigned to a property, return constructor expression (i.e., "box()").
objectSpecifiedName	[out] The object name for Maxscript macrorecorder to use.

Returns

Returns true if a name is specified; otherwise false. If true and objectSpecifiedName is empty, no code will be emitted.

{ return false; }
