Function Documentation

bool FloodHalftile ( TileIndex  t  ) 

Called from water_cmd if a non-flat rail-tile gets flooded and should be converted to shore.

The function floods the lower halftile, if the tile has a halftile foundation.

Parameters:
t The tile to flood.
Returns:
true if something was flooded.

void SetWaterClassDependingOnSurroundings ( TileIndex  t  ) 

Makes a tile canal or water depending on the surroundings.

Must only be used for converting old savegames. Use WaterClass now.

This as for example docks and shipdepots do not store whether the tile used to be canal or 'normal' water.

Parameters:
t the tile to change.
o the owner of the new tile.

void TileLoop_Water ( TileIndex  tile  ) 

Let a water tile floods its diagonal adjoining tiles called from tunnelbridge_cmd, and by TileLoop_Industry() and TileLoop_Track().

Parameters:
tile the water/shore tile that floods
