Im version 2.0 we use direct box2d contact listener, but in version 3.0 i dont find on source anyway to create or set a contact listener.
How i can set a contact listener on PhysicsWorld in cocos2d-x v3.0?
I have not readed cocos2d-x 3.0 document.I found here is a cocos2d-x3.0 project, there is contact listener code in it.[[https://github.com/mahongquan/OpenBird]]but I don't know if it is used in correct way.
There dont have it. The project was made on Lua. It only have a navite class AppDelegate.
I need how can i create/set a PhysicsContactListener in cocos2d-x v.30 (c++).
I dont think that it need be hard.
I found something about it in the v 3.0 release notes: https://github.com/cocos2d/cocos2d-x/blob/develop/docs/RELEASE_NOTES.md#physics-integration
Problem solved with the tutorial and the sample project:https://github.com/Yangtb/newPhysics
