In the following discussion we use body interchangeably with rigid body.Ī fixture binds a shape to a body and adds material properties such as density, friction, and restitution. We briefly define these objects here and more details are given later in this document.Ī shape is 2D geometrical object, such as a circle or polygon.Ī chunk of matter that is so strong that the distance between any two bits of matter on the chunk is constant. There is also a Discord server and a subreddit for Box2D.īox2D works with several fundamental concepts and objects. ![]() You can read about the testbed later in this document. A testbed example that reproduces the problem is ideal. ![]() You can help to ensure your issue gets fixed if you provide sufficient detail. Please file bugs and feature requests here: Box2D Issues The latest version of Box2D may be out of sync with this manual. This manual is only updated with new releases. Please look at the testbed included with Box2D to learn more. This manual covers the majority of the Box2D API. There are many resources for this on the net. Please learn C++ programming, compiling, linking, and debugging before working with Box2D. Box2D should not be your first C++ programming project! You should be comfortable with compiling, linking, and debugging.Ĭaution: Box2D should not be your first C++ project. Since Box2D is written in C++, you are expected to be experienced in C++ programming. You can get these tutorials from the download section of. If not, please first consult Google search and Wikipedia.īox2D was created as part of a physics tutorial at the Game Developer Conference. In this manual I'll assume you are familiar with basic physics concepts, such as mass, force, torque, and impulses. Hopefully this is sufficient to avoid name clashing with your game engine. Most of the types defined in the engine begin with the b2 prefix. From the game engine's point of view, a physics engine is just a system for procedural animation.īox2D is written in portable C++. Programmers can use it in their games to make objects move in realistic ways and make the game world more interactive. Box2D is a 2D rigid body simulation library for games. ![]()
