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
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.
