Physics

The MOOG Environment class takes a moog.physics.physics keyword argument that satisfies the API defined in AbstractPhysics and implements forces on and continuous motion of sprites.

In this directory, the physics.py file contains a Physics class that composes forces, allows multiple updates per environment step, and is suitable for most tasks.

However, for maze-based environments please use the MazePhysics class in maze_physics.py, which constrains sprite motion to a gridworld maze. See the pacman.py for an example.

In this directory are also a variety of forces. These can be configured and combined to simulate many sprite dynamics, though, as with all MOOG components, your are welcome to implment custom forces if those provided are insufficient for your task. If you do so, be sure to inherit from AbstractNewtonianForce if your force is Newtonian or AbstractForce otherwise, both of which are in the abstract_force.py file.
