During the master’s degree, in the Physics for Games class, we developed our own physics engine, including particle motion, collision detection, and force calculation, among other things.

These are some examples of engine mechanics.

1. Particle Motion and Collisions.

The user assigns a velocity and angle, and the particle will be launched at those values. The particle changes direction when colliding with walls. There is no friction in this exercise.

2. Snooker Game.

The user can “hit” the cue ball with the mouse, applying force and direction. Here we can see collisions with static objects (walls and pockets) and dynamic objects (other balls). In addition to collisions and motion, there is friction with the table in this exercise.

3. Thrust Game.

In this exercise, the user controls a spaceship, rotating it with the arrow keys and applying thrust with the spacebar. By being a certain distance away from the particle, we can attach it to the ship. The goal is to reach the ceiling without the ship or the particle colliding with the walls.
