dop2000 Thanks for answer but its not what the documentation says :
Snap(x)
Snap(y)
Snap an X or Y layout co-ordinate to the nearest tile. This also returns a layout co-ordinate, but aligned to the nearest tile in the tilemap.
and thats not what I need , I need TiletoPosition insted
TileToPositionX(x)
TileToPositionY(y)
Convert a tile position to layout co-ordinates. For example, this can be used to position a Sprite object on top of a given tile.
I think this is a Bug
