Foster is a small cross-platform 2D game framework in C#.

★ very work in progress! likely to have frequent, breaking changes! please use at your own risk! ★

To use the framework either

• add a refence to the NuGet package,
• or clone this repository and add a reference to Foster/Framework/Foster.Framework.csproj.

There is a Samples repo which contains various demos and examples that can help you get started.

Check out Discussons or Discord to get involved.

• dotnet 8.0 and C# 12
• SDL2 is the only external dependency, which is required by the Platform library. By default this is statically compiled.

• The Platform library is a C library that implements native methods required to run the application.
• By default, it is currently being built for 64-bit Linux, MacOS, and Windows through Github Actions.
• To add support for more platforms, you need to build the Platform library and then include it in Foster.Framework.csproj

• Implemented in OpenGL for Linux/Mac/Windows and D3D11 for Windows.
• Separate Shaders are required depending on which rendering API you're targetting.
• Planning to replace the rendering implementation with SDL3 GPU when it is complete.

• Taken a lot of inspiration from other Frameworks and APIs, namely FNA.
• This is the second iteration of this library. The first can be found here.
• Contributions are welcome! However, anything that adds external dependencies or complicates the build process will not be accepted.
