Detailed Description

See also: Class Interface, Class DllDir, Class BitmapManager, Class ITreeEnumProc, Class ILoad, Class ISave.

Description:: This is the base class for the creation of Global Utility Plug-Ins.

These plug-ins work as follows: At 3ds Max startup time, before 3ds Max begins its message loop and after all its subsystems are initialized, the GUP Manager will scan the plug-in directory and load all plug-ins with the "<b>*.gup</b>" extension. One by one, the GUP Manager will call the plug-in's Start() method. At that point the plug-in would do its initialization and decide if it wants to remain loaded or if it can be discarded. As an option, it is also possible for a GUP plug-in for make 3ds Max fail and abort all together. If a plug-in wishes to remain loaded (after returning a GUPRESULT_KEEP result code from the Start() method described below), it should start a new thread for its code as there is no other call from 3ds Max.

Unlike other 3ds Max plug-ins, GUP's do not provide a user interface. If developers of GUP plug-ins desire to present an interface, they can develop a standard 3ds Max utility plug-in to do so. See Class UtilityObj. There is some sample code using this technique availalble in /MAXSDK/SAMPLES/GUP/COMSRV/MSCOM.CPP. This Utility plug-in (COMSRV.DLU) accesses the COM/DCOM plug-in and allows the user to "register" or "unregister" the COM interface. See the Advanced Topics section COM/DCOM Interface.

Constructor & Destructor Documentation

◆ GUP()

GUPExport GUP ( )

Remarks: Constructor.

◆ ~GUP()

virtual GUPExport ~GUP ( )

virtual

Remarks: Destructor.

Member Function Documentation

◆ MaxInst()

virtual GUPExport HINSTANCE MaxInst ( )

virtual

Remarks: Implemented by the System.

Returns the application instance handle of 3ds Max itself.

◆ MaxWnd()

virtual GUPExport HWND MaxWnd ( )

virtual

Remarks: Implemented by the System.

Returns the window handle of 3ds Max's main window.

◆ MaxDllDir()

virtual GUPExport DllDir* MaxDllDir ( )

virtual

Remarks: Implemented by the System.

Returns a pointer to an instance of a class which provides access to the DLL Directory. This is a list of every DLL loaded in 3ds Max

◆ Max()

virtual GUPExport Interface* Max ( )

virtual

Remarks: Implemented by the System.

Returns an interface pointer for calling methods provided by 3ds Max.

◆ Bmi()

virtual GUPExport BitmapManager* Bmi ( )

virtual

Remarks: Implemented by the System.

Returns a pointer to the bitmap manager which may be used to manage the use of bitmaps within 3ds Max.

◆ EnumTree()

virtual GUPExport int EnumTree ( ITreeEnumProc * proc )

virtual

Remarks: Implemented by the System.

This may be called to enumerate every INode in the scene.

Parameters:: ITreeEnumProc *proc

This callback object is called once for each INode in the scene.

Returns: Nonzero if the process was aborted by the callback (TREE_ABORT); otherwise 0.

◆ ExecuteStringScript()

virtual GUPExport bool ExecuteStringScript	(	const MCHAR *	string,
		MAXScript::ScriptSource	scriptSource
	)

virtual

Remarks: Implemented by the System.

This method will execute the specified MAXScript command. If a developer needs to ask 3ds Max to do something and this "something" is not implemented within the COM interface, it is possible to send MAXScript commands through this method (and ExecuteFileScript() below). This method will execute whatever string is specified, for instance ExecuteStringScript("open \"MyScene.max"").

Parameters:: MCHAR *string

Points to the MAXScript command to execute. scriptSource

The source of the string containing the MAXScript command to execute.

Returns: TRUE indicates if the command was successfully sent to MAXScript; FALSE if it was not sent. Note that this does not reflect the success of the embedded command.

◆ ExecuteFileScript()

virtual GUPExport bool ExecuteFileScript	(	const MCHAR *	file,
		MSTR *	captured_error_message = `nullptr`
	)

virtual

Executes the given script file.

Parameters

[in]	file	- The fully qualified path to the existing file. This can be maxscript files (.ms, .mxs), maxscript zip files (.mzp), encrypted maxscript files (.mse), or python files (.py, .pyc, .pyw).
[in,out]	captured_error_message	- String for capturing error message, can be nullptr.

Returns: - true if the script was successfully executed, false if not. Note that this does not reflect the result of the script.

Note: - if captured_error_message is not null, no error dialog is displayed if an error occurs.; - if the script file name is persisted in the scene file, the script file should be handled as an Asset and executed using ExecuteScriptAsset(const MaxSDK::AssetManagement::AssetUser& file, MSTR* capturedErrorMessage = nullptr)

Remarks: Implemented by the System.

◆ ExecuteScriptAsset()

virtual GUPExport bool ExecuteScriptAsset	(	const MaxSDK::AssetManagement::AssetUser &	asset,
		MSTR *	captured_error_message = `nullptr`
	)

virtual

Executes the given script file specified as an AssetUser. This function should be used for executing script files whose name is stored in the scene file.

Parameters

[in]	asset	- The asset that points to the existing file. This can be maxscript files (.ms, .mxs), maxscript zip files (.mzp), encrypted maxscript files (.mse), or python files (.py, .pyc, .pyw).
[in,out]	captured_error_message	- String for capturing error message, can be nullptr.

Returns: - true if the script was successfully executed, false if not. Note that this does not reflect the result of the script.

Note: - if captured_error_message is not null, no error dialog is displayed if an error occurs.

Remarks: Implemented by the System.

◆ Start()

virtual GUPExport DWORD Start ( )

pure virtual

Remarks: This method is called at boot time. At that point the plug-in should do its initialization and decide if it wants to remain loaded or if it can be discarded. As an option, it is also possible for a GUP plug-in for make 3ds Max fail and abort all together. Obviously this should be used with caution and plenty of documentation from the part of the developer of the plug-in. If a plug-in wishes to remain loaded (after returning a GUPRESULT_KEEP result code), it should start a new thread for its code as there is no other call from 3ds Max.

Returns: One of the following values:

GUPRESULT_KEEP

Return this to value to have the plug-in remain loaded.

GUPRESULT_NOKEEP

Return this value to discard.

GUPRESULT_ABORT

Return this value to cause 3ds Max to shut down.

◆ Stop()

virtual GUPExport void Stop ( )

pure virtual

Remarks: The Stop() method is called when 3ds Max is going down. The GUP Manager will call this methods for all GUP plug-ins that were maintained in memory right before it discards them. This method is called only for plug-ins that returned GUPRESULT_KEEP for the Start() method above.

◆ Control()

virtual GUPExport DWORD_PTR Control ( DWORD parameter )

inlinevirtual

Remarks: This method is an entry point for external access to GUP plug-in. For instance, Utility plug-ins can invoke their GUP plugin counterpart and have direct access to them.

Parameters:: DWORD parameter

The meaning of this parameter is defined by the plug-in.

Returns: The return value meaning is also defined by the plug-in.

Default Implementation:: { return 0;}

279 { UNUSED_PARAM(parameter); return 0;}

UNUSED_PARAM

#define UNUSED_PARAM(x)

Definition: BuildWarnings.h:18

◆ Save()

virtual GUPExport IOResult Save ( ISave * isave )

virtual

Remarks: This method is called to save any data the plug-in may have into the 3ds Max file.

Parameters:: ISave *isave

An interface used for saving data.

◆ Load()

virtual GUPExport IOResult Load ( ILoad * iload )

virtual

Remarks: This method is called to load any data the plug-in may have from the 3ds Max file.

Parameters:: ILoad *iload

An interface used for loading data.

◆ DeleteThis()

virtual GUPExport void DeleteThis ( )

pure virtual

Called by the system to delete instances of the plugin class.
