Flipping an image changes the bounds of each tile. The existing code assumes that cannot happen. getTile() calculates the tile bounds the first time it is asked for a particular tile. It then caches and returns the same time on every subsequent call. getTile() has a check to test if a tile exists in the cache. If it does not, the tile is created and inserted. In order to make tiles be rebuilt after a flip, we only need to check if the tile's flip matches the image's flip. If not, we can recreate the tile as if it did not exist. To make this a bit clearer, the tile's flipped flag is now set in getTile() rather than positionTile(). This makes setFlip() work. |
