I have three layers:
1) Player
2) Mask (Made with Tileset 1)
3) Hidden Map (Made with Tileset 2)
When i move player on mask I delete tiles to discover map.
I Use : Erase tile range at player.x and player.y position
But this method erase the tile of the mask and the tile of the map.
Is it a bug ? or my mistake??!!
Sorry for my English
