Character versus the world

Now we want to make the main character interact with our world.

We'll add some new methods to the Character module as follows:

1. First we create an object to store our body and shapes as follows:

   function Character:initializePhysics ()
       self.physics = {}

2. Then we add a dynamic body to the physics simulation. This will be the body of our character as follows:

       self.physics.body = 
       PhysicsManager.world:addBody ( MOAIBox2DBody.DYNAMIC )

3. Now we position the body using the same initial position that we used for our rendered character as follows:

       self.physics.body:setTransform (
       unpack(character_object.position) )

4. Now we add a shape. We'll use a square that's the same size as the sprite (64 x 64 ). This is obviously far from ideal, because ...
