(Body Collision listening), collision filters more scalable than the listener, the listener function can be achieved in the filter However, due to the degree of freedom too, is generally not recommended final float RATE = 30 //screen to the proportion of the real world 30px: 1m World world //declare a physical world objects AABB aabb //declare a range of physical world objects Vec2 gravity //declare a gravity vector objects float timeStep = 1f/60f //Physics world analog frequency int iterations = 10 //iteration values, the greater the iterative simulation more accurate, but the lower the performance//--- > > gives force to the first Body Body body1, body2 Shape Properties in the m_isSensor said the collision but no collision effects public void result (ContactResult arg0) {//collision (new points of contact are listening to) will call this function// when the collision will continue to call this function}
