ype of bodies
In box2d there are 3 kinds of bodies
1. Static - These stay fixed at a place and do not move. Like a wall or the floor
2. Kinematic - These move according to their velocity and do not respond to forces acting on it.
3. Dynamic - These are the bodies that move in the simulation according to the forces acting on it. Like the game characters. Dynamic bodies can collide with all other kinds of bodies.
