BEHAVIOUR:
|
||||
-at creation time when LoadMaterials is invocked the class traverse the "scripts/materials" directory and store all existing materials paths
|
||||
-later the game will load the terrain materials from LevelData.xml and call AddTerrainSurface() for each terrain layer, this cause the loading of the
|
||||
assiciated materials
|
||||
-from this point every time a CGF(model) is loaded the 3d engine will call EnumPhysMaterial() with as argument the name of the material
|
||||
specified in 3dsMax,
|
||||
CXSurfaceMgr will:
|
||||
-check if the material exists.
|
||||
-if exists will check if is already loaded
|
||||
-if is loaded will simply return the surface idx
|
||||
-if not will load the material,generate a new surface idx and return it.
