Question

I am making a game. I have been successful with more than one layer on the same scene, but I want there to be collision detection. And the simplest way to do this is to have ONE layer. I don’t know how to add a child to a layer from a different class. HELP!

Answer 1

You can pass the layer you want the child added to in a function.
Like this:

This is in your class:

 -(void)makeChild:(CCLayer*)layer {

 CCSprite *sprite =..**** //Create sprite

 [layer addChild:sprite];

 }

This is in the main layer:

-(void)init {

[classInstance makeChild:self];

}

Hope that helps..
