I'm working with the latest Box2d for flash version, and I'm trying to scale a circle shape in a body (make it smaller in each frame)
I'm looking at this example:http://www.emanueleferonato.com/2009/12/12/scaling-objects-with-box2d/
But I don't understand how to use it with the newer version.
override protected function updateMyLook():void
var circ:b2CircleShape = this._body.GetFixtureList() as b2CircleShape;
var r = circ.GetRadius();
var bBodyShape:b2CircleShape = new b2CircleShape(((r * PhysicsVars.RATIO) - 1) / PhysicsVars.RATIO);
var bBodyFixtureDef:b2FixtureDef = new b2FixtureDef();
bBodyFixtureDef.shape = bBodyShape;
bBodyFixtureDef.density = 0;
bBodyFixtureDef.friction = 0;
bBodyFixtureDef.restitution = 0.5;
bBodyFixtureDef.isSensor = false; // setting as sensor for collusions
but then I cant destroy circ since it is not a fixture. If I'm trying to take fixture from the list, I wouldn't be able to get radius.
can someone show me an example, of how it should be done?
