   I writing a card game but i'm getting stuck with the card swap action and the logic of the game.

   I'm just wondering if i want somebody to find 2 cards that are the same would i have to define every card different from another ? and is there anyway of add some randomness to the position of the cards ?

   I also want that after every two cards touched... that the cards flip back again... is there anyway of counting how many times a card sprite is touched ?

   I wanted to define a class for the card... so it would have it's standard rules and positions where the card maybe able to switch to once a level is done ...

   anyway ... does anyone know anything about making a card game ?

   It's tough to answer any of your question without knowing what you are already doing...

   Are you storing the cards in an array? Have you assigned a tag to the cards or an identifier of some kind to distinguish one from the others? You could use a class wide int to keep track of touches or set a property on the card itself.

   Sounds like you should have a card class of some kind, with properties like numberOfTouches, faceSprite, cardValue, etc.

   yeah,

   I didn't create a class yet because i've already tried and i don't know how to make a class of CCSprite and add a faceUp & faceDown property to the class itself. so i've created 26 cards, 26 Booleans that tells me witch card is up and witch not.
   each card has a tag number, they are all different( i don't know if i can have 2 sprites with the same tag )

   I sketched the logic of the game on paper but i'm stuck when it comes to controlling if a pair is flipped if not { turn them faceDown again }.

   i'm using ccTime to check constantly if a pair is flipped, but when it's not the cards starts flickering and the game crashes.

   -(void)update:(ccTime)dt{

   if (allAnimationsDidFinished && cardTouchCount==2) {

   if (firstSprite == 1 && secondSprite == 24) {
   [[SimpleAudioEngine sharedEngine] playEffect:@"bing.caf"];
   [self removeChild:card01 cleanup:YES];
   [self removeChild:card24 cleanup:YES];
   allAnimationsDidFinished = NO;
   cardTouchCount = 0;
   isFaceUp1 = NO;
   isFaceUp24 = NO;

   }else {
   id flipCardBack = [CCSequence actions: [CCOrbitCamera actionWithDuration:0.35 radius:1 deltaRadius:1 angleZ:270.0
   deltaAngleZ:90.0 angleX:0.0 deltaAngleX:0.0],
   [CCCallFunc actionWithTarget:self selector:@selector(hideSuits)],
   [CCOrbitCamera actionWithDuration:0.35 radius:1 deltaRadius:1 angleZ:0.0
   deltaAngleZ:90.0 angleX:0.0 deltaAngleX:0.0], [CCCallFunc actionWithTarget:self selector:@selector(cardFlippedBack)],nil];

   if (isFaceUp1==YES) {
   [card01 runAction:flipCardBack];
   }}}

   }

   if I choose the right pair it works just fine but if choose the wrong one it crashes...

   i'm using a NSMutableArray for touches and it works fine,

   -(void)selectSpriteForTouch:(CGPoint)touchLocation{
   newSprite = nil;
   for (CCSprite *sprite in touchableCards) {
   if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) {
   newSprite = sprite;
   if (cardTouchCount==0) {
   firstSprite = newSprite.tag;
   }else if (cardTouchCount == 1) {
   secondSprite = newSprite.tag;
   }

   If you want the hole project i can post it.

   Any help is welcome!

   Thanks !
