Updated to latest pixi and p2.js
You can now set the Stage.backgroundColor using either hex or numeric values.
Fresh build. Added pre/post update hooks to Graphics.
Removed input handler from Graphics as it's just meant to be used as a texture really, if you need input events you can apply Graphics to a Sprite.
You can now create a Physics Body directly via game.physics.createBody(), and Body has been updated so it's no longer always bound to a Sprite.
Debug.renderPhysicsBody now works with Rectangles, Lines and multiple Convex shapes.
Starting to get the Tiled polyline parsing working nicely. Not too far off a complete tilemap collision.
Fixed issue with trimmed JSON Hash texture atlases not parsing correctly.
Tilemap.createCollisionObjects will parse Tiled data for objectgroups and convert polyline instances into physics objects you can collide with in the world.
After defining tiles that collide on a Tilemap, you need to call Tilemap.generateCollisionData(layer) to populate the physics world with the data required.
Debug.renderPhysicsBody updated to take camera location and body rotation into account.
Body movement functions put back to velocity :)
Updated to latest dev version of pixi and latest p2.js
Updated docs
New labs demo. Added moveForward and moveBackward to Body.
Removed width/height parameters from addParticle, not needed.
Updated World vastly. No longer extends p2.World due to a few vars we can't alias cleanly, adds in lots of new helper methods.
Ready for Materials and Constraints.
InversePointProxy is for aliasing a p2 typed array when the values need reversing before applying (gravity for example).
Added ContactMaterial support.
