I am quite familiar with cocos2D (been working with it for over 1 year) and I encountered a problem with my multitouch game - the multitouch.
What I have:
[glView setMultipleTouchEnabled:YES] in my delegate.
A playscene that does NOT implement touches.
Many objects (of my own, inherits CCLayer) that are added to playscene.
These objects implement touches and are delegates of the targeted protocol.
[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES];
The very same architecture is used in the touches test from cocos2D and it's working.
The only difference is that they use CCSprite instead of CCLayer as the parent class for the objects.
Does anyone have any ideas?
