Fiziks: A Simple Physics Simulation
Introduction
Welcome to Fiziks, my first foray into physics simulation using TypeScript and Verlet Integration. This project aims to simulate simple 2D particle physics, collisions, and more. Despite its simplicity in places, it serves as a solid foundation for understanding the basics of physics engines.
Why Fiziks?
Physics simulations are a fascinating way to explore the principles of motion, forces, and interactions in a controlled environment. By building Fiziks, I wanted to learn how to simulate physical behaviors and gain hands-on experience with coding a physics engine. This project abstracts as much as possible into the Fiziks class, making it easier to manage and expand.
Features
- 2D Particle Physics and Collisions: Simulates basic particle interactions and collisions in a 2D space.
- Constraints and Links: Creates relationships between particles to form more complex structures.
- Motors: Adds motion to particles, enabling dynamic simulations.
- Rigidbody Physics: Connects cells and links to form rigid bodies that behave realistically.

Bugs
While working on Fiziks, I've encountered a few bugs that I haven't yet ironed out:
- Polygons only have collisions on their points.
