   So, this is a pretty straight forward question. I make a custom class from CCSprite and have it do an action when it is touched. It should create another sprite and display it to the screen. While I can make the new sprite, how do I reference the Scene and add the new sprite to it?

   I stated with the basic Hello World program, so there is still only the Hello World Scene, no others. How do I tell my custom object, "here is the scene, add this new sprite object to it?"

   Thank for your help!

   **Edit**

   Is there also an easy way to have the objects get information about the scene? Like where their position is in the scene?

   Hi! I think you mean a layer instead of scene.
   There are many ways you can do that:

   1)When you create the object, store a reference to the layer inside that object.
   for example CustomObject * myObject = [[CustomObject alloc]initWithLayer:self];
   And in your customobject initwithlayer you assing that reference to a your iVar. Your object should have an MyLayer * layer; iVar.

   2)When you add the layer as a child of the scene you give it a tag. and then retrieve the layer by using the GetChildByTag method

   3) If your object has been added as child of the layer you can get it by using the parent property CCNodes have:
   MyLayer * m = (myLayer)myObject.parent;

   Thanks! I used a variation of your first suggestion to get it to work. If you want, can you explain number two? I've never heard of that, so how would I do it? Thank you again!
