Function Documentation

◆ BuildObject()

void BuildObject ( ObjectType  type,
TileIndex  tile,
CompanyID  owner,
Town town,
uint8_t  view 
)

Actually build the object.

Parameters
typeThe type of object to build.
tileThe tile to build the northern tile of the object on.
ownerThe owner of the object.
townTown the tile is related with.
viewThe view for the object.
Precondition
All preconditions for building the object at that location are met, e.g. slope and clearness of tiles are checked.

◆ CheckBuildableTile()

CommandCost CheckBuildableTile ( TileIndex  tile,
uint  invalid_dirs,
int &  allowed_z,
bool  allow_steep,
bool  check_bridge = true 
)

Checks if the given tile is buildable, flat and has a certain height.

Parameters
tileTileIndex to check.
invalid_dirsProhibited directions for slopes (set of DiagDirection).
allowed_zHeight allowed for the tile. If allowed_z is negative, it will be set to the height of this tile.
allow_steepWhether steep slopes are allowed.
check_bridgeCheck for the existence of a bridge.
Returns
The cost in case of success, or an error code if it failed.
