A Dart 2D physics engine

Build Status Coverage Status

This is a Dart port of Java's Box2D libraries.

The Java Box2D library was originally written by Daniel Murphy (status February 2015).

lib/                     Port of Daniel Murphy's jbox2d

First Dart port of an earlier version of Box2D library was done by Dominic Hamon. We are grateful for his work.

0.4.0

  • Breaking: Made package strong-mode compliant (with implicit-casts and implicit-dynamic off). This means many API points are now more strongly typed (num is now double). Fix errors by providing doubles where they are expected (1 will become 1.0 and num fraction = .5 will become double fraction = .5), and explicitly casting joints (world.createJoint(jointDef) as RevoluteJoint).
  • Pulled in optimizations and bug fixes from the original jbox2d project.
  • Made velocityThreshold mutable (as per jbox2d and other box2d implementations).

0.3.0

  • Updated to vector_math 2.0.0

0.2.0

  • Complete re-write. Many APIs have changed.

The description is too short.

Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

Package is pre-v1 release.

While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction of the API.

Maintain an example.

None of the files in your example/ directory matches a known example patterns. Common file name patterns include: main.dart, example.dart or you could also use box2d_flame.dart.
