Rotateing tile

If the tiles are directional, such as on a wall or corner of a house, the tiles themselves must be changed, not just repositioned. In such cases, the following custom data layers control this.

• tile_name
• order_id

For tile_name, give the same name to tiles that are oriented differently but the same. The tiles will change as the tile map rotates.
If tiles with tile_name are arranged clockwise, order_id need not be used. If they are not clockwise, put order_id so that they are clockwise.

Rotation will not work correctly in the following cases

• There are more than 4 tiles with the same tile_name.
• There are 3 tiles with the same tile_name.
• Tiles with the same tile_name have order_id or not.
