Game Physics

Want to learn how to create and apply game physics without using an exisiting physics engine. To start I put together a simple rigid body prototype that can handle both velocity & angular velocity that allows to move & rotate an object based on forces being applied to it.

This will be updated over time, for now I'll be focused on getting a sphere to run along a set of marble tracks provided by the great Kenney.

Source Code : https://github.com/sketchpunklabs/gamephysics

Prototypes
  1. Marble drop onto slope track using raycasting & rigidbody
  2. Marble drop using 5 raycasts for surface detection and force computation
  3. SphereCast Marble Tiles
  4. Marble drop using sphereCast for surface detection and force computation
