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.
