# Work In Progress
This engine is still in development but the implemented features include:
- Modular Systems
- Behaviour System
- 2D Physics Engine(**Not Fully Completed, but usable**)
- Rigid Body Simulations
- Collision Detection (Convex Shape & Circle)
- Collision Resolution (**Not Fully Completed**)
- Vector2D, AABB, Circle, Line, LineEquation, Projection & Shape Data Types
- General Math
---
**A detailed README file will be written in the future. If you want to check out how to use this, please checkout this example Pong game made using this engine on top of [MonoGame](https://monogame.net/) from the link bellow.**
