setBounds(x, y, width, height, left, right, top, bottom, setCollisionGroup)
Sets the bounds of the Physics world to match the given world pixel dimensions.You can optionally set which 'walls' to create: left, right, top or bottom.If none of the walls are given it will default to use the walls settings it had previously.I.e. if you previously told it to not have the left or right walls, and you then adjust the world sizethe newly created bounds will also not have the left and right walls.Expli
