Store metadata for tile in Tiled Map Editor In my tilemap based game, I need to associate lights with light switches, buttons with doors etc. I am using the Tiled map editor (mapeditor.org), but I have yet to find a way to store these associaltion. My idea is to store a number with each tile, so I can have groups of tiles that interact with each other. Is there a way to store custom data with each tile in the Tiled map editor? Just to be clear I don't want to store custom data with each tile type, but with individual instances of one tile type.
