◆ TerraformTile_Object()

CommandCost TerraformTile_Object	(	TileIndex	tile,
		DoCommandFlags	flags,
		int	z_new,
		Slope	tileh_new )

static

Tile callback function signature of the terraforming callback.

The function is called when a tile is affected by a terraforming operation. It has to check if terraforming of the tile is allowed and return extra terraform-cost that depend on the tiletype. With DoCommandFlag::Execute in flags it has to perform tiletype-specific actions (like clearing land etc., but not the terraforming itself).

Note: The terraforming has not yet taken place. So GetTileZ() and GetTileSlope() refer to the landscape before the terraforming operation.

Parameters

tile	The involved tile.
flags	Command flags passed to the terraform command (DoCommandFlag::Execute, DoCommandFlag::QueryCost, etc.).
z_new	TileZ after terraforming.
tileh_new	Slope after terraforming.

Returns: Error code or extra cost for terraforming (like clearing land, building foundations, etc., but not the terraforming itself.)
