   Hey guys,
   so this might be an easy question but can you not add bools to easy sprites? what im trying to do is put the sprites in an array which works perfectly. but i also have a bool of canSelect but if i do:
   [player1Sprite setCanSelect: YES];

   i get a warning saying:
   'AtlasSprite' may not respond tp '-setCanSelect'

   Can you not do bools with AtlasSprites?
   Thanks

   What you should do is create a class which would have an AtlasSprite instance variable and a bool "canSelect" instance variable along whatever else you need.

   What is player1Sprite an instance of? I would make a class called PlayerSprite or something that inherits AtlasSprite if you aren't already doing this. Inside PlayerSprite you would have your bool so it would look like this:

   @interface PlayerSprite : AtlasSprite
   {
   bool canSelect;
   }
   @property (readwrite, assign) bool canSelect;
   @end

   and your implementation would look like this:

   @implementation PlayerSprite
   @synthesize canSelect;
   @end

   Now you can get and set your variable directly by going:

   player1Sprite.canSelect = YES;

   make sure youve defined player1Sprite as:

   PlayerSprite * player1Sprite;

   and not:

   AtlasSprite * player1Sprite;

   incidentally fyi if you do it the 2nd way, the compiler will throw up warnings (which you should fix!), but bc ObjC is pretty dynamic it will run fine. But fix the warnings anyway :)

   Ok well what i have is this:
   http://pastie.org/544356
   For:
   [PlayerSprite track:player1Sprite];
   Im getting a warning passing argument 1 of 'track' from distinct Objective-C type

   and for:
   [player1Sprite SetCanSelect:YES];
   im gettting a warning 'AtlasSprite' may not respond tp '-SetCanSelect'

   any ideas?
   Thanks

   You still dont show (in MainLayer I assume) where player1Sprite is defined! As I posted earlier, define it as:

   PlayerSprite * player1Sprite;

   and not:

   AtlasSprite * player1Sprite;

   also, fyi, cocoa methods start with a lowercase. Also you can use properties instead of defining all those getters and setters. hth, Codemattic

   Hey Codemattic,
   I actually did have that in there i just had a typo and its all working now but it is crashing now whenever i do player1Sprite.canSelect = YES;
   the log is:
   *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[AtlasSprite setCanSelect:]: unrecognized selector sent to instance 0xe98e90'
   not sure why its not working.
   Thanks

    maybe bc you called your method -CanSelect and the compiler makes player1Sprite.canSelect look for the method -canSelect and case matters. Not sure.

    well i changed everything to use property so i dont have all the getters and setters. and i ran throught all my code to check i didnt forget to change anything and i didnt but everytime it gets to player1Sprite.canSelect = YES; it will crash
    Thanks

    Then maybe you have a leak with player1Sprite? Create the smallest full example of your problem and post that and I guarantee we will solve it.
