Question

I’m handling the touches manualy through a class that holds every touchable sprite. Also, every menu is a CCLayer, and when I change from one menu to the other, I use the CCTransition### and get the new scene.

So, the layers are “still there” and when I touch one menu, the previous layer also receive it… like when I start the game in a new CCLayer, and then the menus are still affected for the multi touch…

If I use single touch, I can swallow the touches, but the game must have multi touch…

What can I do? Thank you all!

You need to consume the touch event in whatever layer needs it. After a layer consumes it, the touch will no longer be propagated to “previous” layers.

To consume a touch event, you return YES in the ccTouchBegan delegate method.

EDIT: changed method name to match CCStandardTouchDelegate

- (BOOL)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event;
   if (condition)
      return YES;
   else 
      return NO;
}
