Questions tagged [nape]

Nape is a powerful, fast, and friendly 2D Rigid Body physics engine for AS3/Haxe. Nape is open-source and free to use for personal and commercial projects.

Nape is a 2D rigid body physics engine designed for games, written in Haxe, and supporting all Haxe targets. Nape is compiled into .swc libraries for AS3 users.

Nape is higher performing than Box2D solutions in AS3/Haxe, and its memory usage is stable and far less than Box2D. Nape supports the majority of Box2D features, as well as many features not included in Box2D such as the geometric utilities, the high-level callbacks system, and more sophisticated buoyancy.
