Re: [Flashcoders] setting the centerpoint of a movieclip?
I took a rotateZ method from Robert Penner's Vector3D class and added
a pivotpoint to the formula. It works pretty well as a dynamic
registrationpoint :)
var mc:MovieClip;
var position:Object = {x:mc._x, y:mc._y};
var pivot:Object = {x:position.x+mc._width/2, y:position.y+mc._height/2};
var angle:Number = 0;
onEnterFrame = function():Void {
angle += 5;
rotate(angle);
}
function rotate(angle:Number):Void {
var ca:Number = cosD(angle);
var sa:Number = sinD(angle);
var x = (position.x - pivot.x) * ca - (position.y - pivot.y) * sa;
var y = (position.x - pivot.x) * sa + (position.y - pivot.y) * ca;
mc._x = pivot.x + x;
mc._y = pivot.y + y;
mc._rotation = angle %= 360;
}
function sinD(angle:Number):Number {
return Math.sin (angle * (Math.PI / 180));
}
function cosD(angle:Number):Number {
return Math.cos (angle * (Math.PI / 180));
}

That'll do it! Thanks.
