Description
A circle shape.
Examples
Creating a circle body
--create ball bitmap object from ball graphic
local ball = Bitmap.new(Texture.new("./ball.png"))
--reference center of the ball for positioning
ball:setAnchorPoint(0.5,0.5)
ball:setPosition(x,y)
--get radius
local radius = ball:getWidth()/2
--create box2d physical object
local body = world:createBody{type = b2.DYNAMIC_BODY}
body:setPosition(ball:getX(), ball:getY())
body:setAngle(ball:getRotation() * math.pi/180)
local circle = b2.CircleShape.new(0, 0, radius)
local fixture = body:createFixture{shape = circle, density = 1.0,
friction = 0.1, restitution = 0.2}
