This project is a 2D physics engine written in C++.

The wiki is hosted on Read The Docs and the API Documentation (Doxygen) on GitHub Pages.

It has :

• Circle -> Circle collisions
• Circle -> AABB collisions
• AABB -> AABB collisions
• A failed attempt at SAT
• A failed attempt at GJK
• Broad phase collision detection with a grid

1. Get a C++20 compiler
2. Build with CMake :

cmake -S . -B .\build\
cmake --build .\build\

When building in Debug mode, you need to rename freetyped.dll to freetype.dll in the folder where Demo.exe is located. I don't know why this is necessary, but I guess it's a problem with my CMake setup with SFML.

The physics engine doesn't have any dependencies, and can be built alone as a library.

The demo scene has a dependency on SFML but it is retrieved using CMake's FetchContent so you don't have to use something like vcpkg.

There are two main folders in this project :

• StowyPhysicsEngine
• Demo

StowyPhysicsEngine is the physics engine in itself. It is setup as a CMake library.

Demo is the SFML project to visualise the physics engine.

They each have their own CMakeList.txt but there is also a main one that includes both to be able to build everything at once.
