I'm trying to create a sample game, where using tilemap.
Now I want to change tile of map layer at a fix coordinate, so I call to setTileGID(gid, index), but instead of removing old tile and adding new one, cocos2d just places the new one overlap the old :;qst
How can I fix it? Or is it a cocos2d bug?
FYI: I'm coding on Ubuntu with Webstorm and testing on Google Chrome.
