Physics如何获取碰撞的物体碰撞的点

Cocos2d-x
#1 
bool Game::onContactBegin(PhysicsContact& contact){
    Sprite* spriteA = NULL; 
    Sprite* spriteB = NULL; 

    spriteA = (Sprite*)contact.getShapeA()->getBody()->getNode(); 
    spriteB = (Sprite*)contact.getShapeB()->getBody()->getNode(); 
    }


```


有什么办法获取spriteA和spriteB碰撞时相交的点？？？
#2

contact.getContactData()->points 即可获取到碰撞的坐标点
