Detailed Description

Main scene access.

IGameScene is the main entry point for an exporter. It contains the initialisation routines and access to the nodes and materials of the scene. The user can ask IGame to enumerate the whole scene, selected nodes or single nodes, with or with out hierarchy.

Constructor & Destructor Documentation

◆ ~IGameScene()

virtual ~IGameScene ( )

inlinevirtual

Destructor.

175 {;}

Member Function Documentation

◆ SetPropertyFile()

virtual void SetPropertyFile ( const MCHAR * fileName )

pure virtual

Set the Property File to use.

You can define the name of the file to use, including full path, that IGame uses to parse for the supported parameters. This means that you could have multiple configs depending on the various games in development. You must call this before you call InitialiseIGame(). By default the the filename will be the maxroot/plugcfg/IGameProp.XML.

Parameters

fileName The name of the property file to use inthis session.

◆ InitialiseIGame() [1/3]

virtual bool InitialiseIGame ( bool selected = false )

pure virtual

Initialise IGame.

IGame can be initialised specifying whether to search for selected nodes only

Parameters

selected True if selected are searched for - default false

Returns: True if the scene was enumerated - A Possible reason for failure is that the Parameter IGameProp.XML file was not found or not parsed correctly

◆ InitialiseIGame() [2/3]

virtual bool InitialiseIGame	(	INode *	root,
		bool	Hierarchy = `true`
	)

pure virtual

Initialise IGame with a specific node.

Developer can specify a single node to parse.

Parameters

root	The actual node to parse
Hierarchy	lets IGame know to initialise the children of the node

Returns: True if the scene was enumerated - A Possible reason for failure is that the Parameter IGameProp.XML file was not found or parsed correctly

◆ InitialiseIGame() [3/3]

virtual bool InitialiseIGame	(	Tab< INode * >	nodes,
		bool	Hierarchy = `true`
	)

pure virtual

Initialise IGame with a specific set of nodes.

Developer can specify a set of nodes to parse. This could be implemented by creating a Tab using the 3ds Max sdk. Look at Interface::GetSelNodes() and Interface::GetSelNodeCount().

Parameters

nodes	The actual tab containing the nodes to parse
Hierarchy	lets IGame know to initialise the children of the node

Returns: True if the scene was enumerated - A Possible reason for failure is that the Parameter IGameProp.XML file was not found or parsed correctly

◆ GetSceneFileName()

virtual const MCHAR* GetSceneFileName ( )

pure virtual

Get the active filename.

Returns: The current filename

◆ SetStaticFrame()

virtual void SetStaticFrame ( int frameNum )

pure virtual

Set the static frame.

Specify the frame to use for Time access functions

Parameters

frameNum The static frame to use - Internally this will be converted to Ticks

◆ GetSceneStartTime()

virtual TimeValue GetSceneStartTime ( )

pure virtual

Get the start of the animation range.

This provides the animation start time in ticks

Returns: The start time in ticks

◆ GetSceneEndTime()

virtual TimeValue GetSceneEndTime ( )

pure virtual

Get the end of the animation range.

This provides the animation end time in ticks

Returns: The end time in ticks

◆ GetSceneTicks()

virtual int GetSceneTicks ( )

pure virtual

Get the number of ticks per frame.

Returns: The number of ticks per frame

◆ GetTopLevelNodeCount()

virtual int GetTopLevelNodeCount ( )

pure virtual

All node access is provides by parent nodes.

This does not include the Root node as in 3ds Max. This method can be used to traverse the scene

Returns: The number of parent nodes

◆ GetTotalNodeCount()

virtual int GetTotalNodeCount ( )

pure virtual

Get the complete number of nodes.

The is useful for implementing a progress bar in the exporter

Returns: The total node count

◆ GetTopLevelNode()

virtual IGameNode* GetTopLevelNode ( int index )

pure virtual

Get the actual toplevel node.

A Top level node is a node at the top of the Hierarchy, i.e it has no Parent.

Parameters

index The index into the the toplevel parent list

Returns: A pointer to a IGameNode

See also: IGameNode

◆ GetRootMaterialCount()

virtual int GetRootMaterialCount ( )

pure virtual

Get the total number of parent materials.

This does not include sub materials - just the number of actual material containers

Returns: The total number of parent materials

◆ GetRootMaterial()

virtual IGameMaterial* GetRootMaterial ( int index )

pure virtual

Access to the Root Material.

This is the parent material that is stored on the Node. The material will host any sub materials and access is provided by the IGameMaterial interface.

Parameters

index The root material to access

Returns: A Pointer to an IGameMaterial

See also: IGameMaterial

◆ GetIGameNode() [1/2]

virtual IGameNode* GetIGameNode ( INode * node )

pure virtual

Access the IGameNode from the supplied INode.

Some IGame methods provide access to INode lists. You can use this method to retrieve the IGameNode equivelent IGame must be initialised first, as the node must be in the Database

Parameters

node	The 3ds Max node to find

Returns: A pointer to IGameNode, NULL if not found

◆ GetIGameNode() [2/2]

virtual IGameNode* GetIGameNode ( ULONG NodeID )

pure virtual

Access the IGameNode from the supplied Node ID.

You can use this method to retrieve the IGameNode based on a Node ID IGame must be initialised first, as the node must be in the Database

Parameters

NodeID The Node ID to find

Returns: A pointer to IGameNode, or NULL if not found

◆ GetIGameNodeByType()

virtual Tab<IGameNode*> GetIGameNodeByType ( IGameObject::ObjectTypes Type )

pure virtual

Access the set IGameNodes from the specified IGame Type.

You can use this method to retrieve the IGameNode based on IGameObject::ObjectTypes. IGame must be initialised first, as the node must be in the Database

Parameters

Type	The IGameObject::ObjectTypes to find

Returns: A Tab of IGameNodes. The developer should check the Count() method to see if any were found

◆ GetIGameMaterial()

virtual IGameMaterial* GetIGameMaterial ( Mtl * mat )

pure virtual

Access the IGameMaterial from the supplied Mtl.

You can use this method to retrieve the IGameMaterial equivelent IGame must be initialised first, Material doesn't have to be part of database

Parameters

mat	The 3ds Max Material

Returns: A pointer to IGameMaterial

◆ GetIGameTextureMap()

virtual IGameTextureMap* GetIGameTextureMap ( Texmap * texMap )

pure virtual

Access the IGameTextureMap from the supplied Texmap.

You can use this method to retrieve the IGameTextureMap equivelent IGame must be initialised first, Texture doesn't have to be part of database

Parameters

texMap The 3ds Max Texture Map

Returns: A pointer to IGameTextureMap

◆ ReleaseIGame()

virtual void ReleaseIGame ( )

pure virtual

Releases IGame and free all associated memory.

This must be called after you have finished with IGame. It makes sure all data is freed and general clean up is performed. Without calling this there is the risk of corrupting memory, and causing incorrect data to returned the next time IGame is run
