Creating a circle body <syntaxhighlight lang="lua"> --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} </source>

Methods b2.CircleShape.new b2.CircleShape:set sets the center point and radius
