| To define which areas of a body interact with the rest of the world and those different surfaces, you need to add one or more Shapes to a body. There are 3 types of shapes available with Chipmunk: circle, segment and poly. Combining those 3 shape types you can define almost any area of interaction imaginable for your bodies. Obviously, shapes added to the same body don't produce collisions between themselves. | To define which areas of a body interact with the rest of the world and those different surfaces, you need to add one or more Shapes to a body.

| The main method of changing things on Chipmunk, just like in the real world, is to use and apply Forces. A force is a vector , you tell the strength along the XX and YY axis. To help working with vectors, Chipmunk comes with a library called cpVect that allows you to do the most common operations like multiplying vectors or projecting two vectors. | The main method of changing things on Chipmunk, just like in the real world, is to use and apply Forces.
