Physics: Falling Objects There are many variations on how to incorporate the physics engine using display objects. So far we have worked with removing objects with collisions, moving objects through the stage area, and launching objects by applying force against gravity, just to name a few. Now we're going to explore another mechanism that allows gravity to control the environment. The next game we'll be creating deals with falling physical objects. 7 Points that will be discussed in this chapter are: Working with more physics bodies Customizing the body construction Tracking the objects caught Working with post-collisions
