Class Description

Simple wrapper for 3ds Max objects.

This is heart of the interaction with 3ds Max objects. 3ds Max objects are converted to IGame objects to provide simpler interfaces. Specific support is given to Meshes, Splines, Helper (including bones) and Cameras. Any object that is not supported by IGame directly is supported as a generic object, so that properties can be extracted easily. At the present time IGame only supports Geom Objects that can be converted to a Tri Object.
A note about XRef items. IGame will search out XRef Objects and store them as IGameXrefObject. External file names and proxies can be accessed by casting IGameObject* to IGameXrefObject*
Some of the interfaces returned by IGameObject require that the nodes be parsed by IGame first.

Constructor & Destructor Documentation

IGameObject ( )

Default constructor.

IGAMEEXPORT IGameObject ( INode * node )

The IGameObject constructor.

Parameters

*node The 3ds Max node to initialise

virtual ~IGameObject ( )

pure virtual

Member Function Documentation

void SetNode ( INode * n )

protected

IGAMEEXPORT void GetBoundingBox ( Box3 & bb )

The bounding box of the object.

Parameters

bb	The Box3 to receive the value

IGAMEEXPORT bool IsRenderable ( )

Check if object renderable.

Returns: TRUE if it is renderable

virtual ObjectTypes GetIGameType ( )

pure virtual

The IGame object type.

Return the Type of IGameObject it represents

Returns: The object type. Returned value corresponds to IGameObject::ObjectTypes Enum

IGAMEEXPORT Object* GetMaxObject ( )

Access to the actual 3ds Max object.

Access to the actual 3ds Max object, if further direct access needed

Returns: A pointer to a max Object class

IGAMEEXPORT MaxType GetMaxType ( )

The 3ds Max object type.

This lets the developer know what type of object - Light, Geom, Helper etc... This is different from the IGame types, as these may group more than one type of 3ds Max object together. The information can be used to cast Object returned from IGameObject::GetMaxObject to the appropriate class.

Returns: The type of max object. This is defined as the IGameObject::MaxType enum

IGAMEEXPORT int GetNumModifiers ( )

The number of modifiers active on the object.

Returns: The number of modifiers

IGAMEEXPORT IGameModifier* GetIGameModifier ( int index )

Access to IGame modifier.

Get a pointer to the IGame representation of the modifier

Parameters

index The index of the modifier to return

Returns: A pointer to the IGameModifier

IGAMEEXPORT bool CastShadows ( )

Check if Object casts shadows.

Returns: TRUE if object casts shadows

IGAMEEXPORT bool IsObjectSkinned ( )

Check if object skinned.

Is object skinned with either Physique of Skin

Returns: TRUE if skinned

IGAMEEXPORT IGameSkin* GetIGameSkin ( )

Access to the Skin interface.

Returns: A pointer to IGameSkin or NULL if not present

IGAMEEXPORT bool IsObjectXRef ( )

Check if XRef object.

Indentify XRef objects

Returns: TRUE if it is an XRef Object

IGAMEEXPORT GMatrix GetIGameObjectTM ( )

Access to the ObjectTM.

Get the ObjectTM. This is the matrix needed to calculate world space

Returns: A matrix containing the Object TM. Used to calculate world space.

virtual bool InitializeData ( )

inlinevirtual

Extract the 3ds Max data into IGame data.

Some extraction processes are time and memory consuming. This method allows the developer to specify when they want the data to be converted - this prevents any unwanted data being converted. This is important for IGameMesh class - if you are just after parameter data, you don't want the whole vertex array being sorted. Calling this tells the object that you want the data be converted.

Returns: It will return FALSE when data has not been converted, this object should not be exported. Usually this is due to a standin or in the case of a GeomObject, it can't be converted to a Tri Object.
