Typedef Documentation

◆ TileIndexDiff

typedef int32_t TileIndexDiff

An offset value between two tiles.

This value is used for the difference between two tiles. It can be added to a TileIndex to get the resulting TileIndex of the start tile applied with this saved difference.

Enumerator
LM_LEVEL 

Level the land.

LM_LOWER 

Lower the land.
