## 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.
