Enumerations | |
enum | HeightmapRotation { HM_COUNTER_CLOCKWISE, HM_CLOCKWISE } |
Order of these enums has to be the same as in lang/english.txt Otherwise you will get inconsistent behaviour. More... |
Functions | |
bool | GetHeightmapDimensions (char *filename, uint *x, uint *y) |
Get the dimensions of a heightmap. | |
void | LoadHeightmap (char *filename) |
Load a heightmap from file and change the map in his current dimensions to a landscape representing the heightmap. | |
void | FlatEmptyWorld (byte tile_height) |
Make an empty world where all tiles are of height 'tile_height'. | |
void | FixSlopes () |
This function takes care of the fact that land in OpenTTD can never differ more than 1 in height. |
