Question

I have a little app up that has both CCLayer view and UIView. That works fine. I am simply trying to send a message to a reference of the layer so the Cocos2d CCLayer can receive the message. This seems simple and I’d think should work. I created a CCLayer pointer called “cocos” as an iVar and set it as this after creating the cocos view:

[[CCDirector sharedDirector] runWithScene: [HelloWorldLayer scene]];

CCScene*tempscene=[[CCDirector sharedDirector] runningScene];
cocos=[tempscene.children objectAtIndex:0];

As this is a simple little test app with just one scene and layer, it should work. But the iVar cocos doesn’t respond to any of the public methods in HelloWorldLayer. Any idea why?

UPDATE: I got it to work by simply re-arranging the code a bit. Not sure why it worked this way and not the prior way:

  CCScene*tempscene=[HelloWorldLayer scene];
[[CCDirector sharedDirector] runWithScene: tempscene];


cocos=[tempscene.children objectAtIndex:0];

Answer 1

The reason that the first bit of code didn’t work for you is that runWithScene: doesn’t immediately set the runningScene property of CCDirector to [HelloWorldLayer scene].
