In this episode I go over how to make a pillbox collider using circle colliders and box colliders (or fixtures) in Box2D. Then I talk about how to start building the player controller. I go over how to create a fake velocity and acceleration to give the player controller a fine level of control while still being able to use Box2D to handle all collisions.
