Constructor & Destructor Documentation
§ CDynamicTerrainLoader()
| CDynamicTerrainLoader::CDynamicTerrainLoader | ( | const char * | sConfigFile | ) |
fTerrainTileSize: In case a world is extremely large, it can be divided into a matrix of square tiles of a given size, called terrain tile size.
Terrain data can be selectively loaded to the game world. Remember, all world objects are created using the world coordinate system, not the terrain tile's location system. if fWorldSize<=fTerrainTileSize, it is assumed that there is only a single terrain tile in the entire world.
Member Function Documentation
§ LoadTerrainAt()
|
virtual |
Called by the TerrainLattice when a Terrain object in the lattice has entered the visible region and, therefore, needs to be loaded into RAM.
this function will always return a valid terrain. If there is no terrain data, a default terrain is returned.
- Parameters
-
pTerrain the terrain object to be filled with data. If it is NULL, a new terrain object will be created.
- Returns
- : the loaded terrain object is returned.
Implements ParaTerrain::TerrainLatticeLoader.
§ SaveWorldConfigFile()
|
virtual |
save world config file to disk.
Implements ParaTerrain::TerrainLatticeLoader.
§ UnloadTerrain()
|
virtual |
Called by the TerrainLattice when a Terrain object in the lattice is no longer within the visible region and can, therefore, be disposed of, freeing RAM for other visible Terrain objects.
- Parameters
-
pTerrain the terrain object will be reduced a blank terrain after calling this function.
Implements ParaTerrain::TerrainLatticeLoader.
§ UpdateTileConfigFile()
|
virtual |
update the tile config file for the terrain terrain tile x,y.
return true if succeeded. One needs to SaveWorldConfigFile() in order for the changes to be written to disk.
- Parameters
-
sTileConfigFile if "", it will erase the tile. otherwise it will change the config file.
