3 sweep github code#
LibGDX uses a Java wrapper around native Box2D code written in C++ as its physics engine. The LiquidFun physics engine is a fork of Box2D by Google, which adds fluid simulation to the engine. The physics engine used in SpriteKit for iOS and OS X uses Box2D internally. The Chipmunk physics engine (written in C) and Phys2D (written in Java) are both partially based on Box2D Lite. Box2D Lite uses many of the same algorithms as Box2D, but has a smaller feature set.
3 sweep github series#
Related engines Īn earlier version of the Box2D engine, now known as Box2D Lite, was released primarily for educational purposes, based on a series of yearly Game Developers Conference presentations that Erin Catto has given. These algorithms allow efficient simulations of fast bodies and large stacks without missing collisions or causing instabilities.

The engine also applies gravity, friction, and restitution.īox2D's collision detection and resolution system consists of three pieces: an incremental sweep and prune broadphase, a continuous collision detection unit, and a stable linear-time contact solver. Bodies are joined with joints and acted upon by forces. It can simulate bodies composed of convex polygons, circles, and edge shapes.

BBC Basic for SDL, cross-platform version of BBC Basic.On October 30, 2009, it was announced that Box2D was being integrated into the (now older) Torque 2D game engine. Bindings exist to use the compiled library from Python, DarkBASIC and BBC BASIC. The engine has been ported to many other programming languages and environments, including Java, Adobe Flash (in ActionScript and Haxe languages), C#, Lua, JavaScript, and D. The engine may be compiled in fixed point and floating point modes, and has been used on the Nintendo DS, Wii, and several mobile phones (including Android, BlackBerry 10 and iOS) as well as most major operating systems. Cross-platform availability īox2D is itself written in platform-independent C++ (usable on any system with a C++ compiler available).
3 sweep github license#
On July 27, 2020, version 2.4 was launched, with a variety of changes, most notably the license was changed to the MIT License. On March 6, 2008, version 2.0 was launched, introducing continuous collision detection and revamping the API. On July 12, 2015, hosting was moved again, this time to GitHub. On January 17, 2010, Box 2D moved the project to Google Code for hosting. On September 11, 2007, it was released as open source on SourceForge. Box2D was first released as "Box2D Lite", a demonstration engine to accompany a physics presentation given by Erin Catto at GDC 2006.
