Getting a reference to the Scene currently running?

So... I have a scene class that has a CGPoint for velocity.

I have a helicopter class that is my sprite for a copter. In the ccTouchesEnded of the copter class I want to change the scenes CGPoint. How do I get a reference to my scene so that I can change this value, is it something to do with the director?

In regular iPhone programming I would use an appDelegate but I'm not sure how this works in cocos2d.

Thanks!

It's a bit ugly, but when I had to do something similar, I used [parent doSomething];

You'll get a warning about Cocosnode not supporting the doSomething method, but if it's implemented in your scene (and your scene is the sprite's parent), it'll work just fine.

@Nicke, if you want to suppress that warning just do it like:

[(MyScene*)parent doSomething];

I have the same problem,

when I add the script [(MyScene*)parent doSomething];

there is no error, but the function will not run......

make sure parent is a MyScene type object. Do:

NSLog([parent description]);

to see what it is.

Wow, that description property is useful. Thanks Codemattic!
