Force Generators (Abstracting Forces) | Coding a 2D Physics Engine in Java #12
0Join the Discord: https://discord.gg/4tHeAkxNg7
In this episode, I go over this concept that was created by Ian Millington (to the best of my knowledge), that allows us to abstract the application of forces into a generic container. This makes creating different types of forces to apply to objects in the game world very easy. We will eventually use this to create gravity, drag force, spring force, and possibly buoyancy forces. I also go over some helper functions that will make our lives easier in the future.
