Box2D.NET

Examples

Box2D.NET is a C# binding for Box2D. Low-level bindings to the C api are included and generated with Bindgen.NET. Native libraries are cross-compiled with Vezel-Dev's Zig Toolsets.

Note

There is currently no high-level wrapper but it may come in the future! Box2D.NET and Box2D.NET.Bindings are identical packages.
