   Hi,

   I have found this in the docs:

   Technical description: Each layer is created using an TMXLayer (subclass of CCSpriteSheet). If you have 5 layers, then 5 TMXLayer will be created, unless the layer visibility is off. In that case, the layer won't be created at all. You can obtain the layers (TMXLayer objects) at runtime by:

   First of all, how can I set this visiblity to off in tiled? Is it settig opacity to 0? Is it a property of the layer?.

   In the other hand, I have layers that are just information, what's the best way to make them not render? I have though about loading the map, and then do a removeChild from the node they are attached, but don't know if this is the correct way to do it.

   Thanks in advance,
   HexDump.

   hexdump,

   If you don't want render a given tilemap, then just don't add it as a child to a layer.

   Hope this helps,

   CCTMXlayer *myInfoLayer = [<your tilemap> layerNamed:@"layername"];
   myInfoLayer.visable = NO;

   Keep in mind "layername" is the name you gave your layer that you want hidden in TileD. <your tilemap> is your main CCTMXTiledMap.

   That will prevent the layer from being drawn.

   Hope this helps.

   Hi again,

   Sorry I forgot to ask a little question before. I suppose that when loading a layer anyway it is info or not, cocos2d will generate a bunch of sprites for it. Is there anyway to free all this sprites to get some mem back? I won't need it because I just used the tilesInfo data.

   Thanks in advance,
   HexDump.

   The other question is how many different tiles are you using on the marking map? I would think you would only have a couple, in which case it probably won't effect the outcome very much if it generates a single small sprite.

   Just don't waste an entire 1024 texture for a marking layer.

   If you give us a little more insight as to what you are trying to accomplish we might be able to help better.

   Regards,

   You might want to use Object layers (which aren't drawn and thus don't get spritesheets etc) for your layer information. Good tutorials on that at http://www.raywenderlich.com/1163/how-to-make-a-tile-based-game-with-cocos2d

   He uses an object layer for the spawn points and so on.
