I'm writing a game for Mac OS using cocos2D and Box2D. I've added a b2ContactListener
subclass to my world as follows:
contactListener = new ContactListener();
world->SetContactListener(contactListener);
This works perfectly, but I am unsure of the best/accepted way to access the contact listener from other classes that don't currently have a direct reference to the contact listener.
I know I can pass a reference to other classes that need it, but what I was wondering is if there is a better way. More specifically, although I can't find a method to do this, is there some equivalent of this:
world->GetContactListener();
in Box2D?
The reason I am trying to do this is simply because I would prefer to move some game logic (i.e. whether a body is able to jump based on information from the contact listener) to the relevant classes themselves, rather than putting everything in the main gameplay class.
Thanks!
