Rotation around specific x and y values

1

Hi there,

I was wondering if there’s a way to rotate a movie clip around a specific x & y value? I’ve been looking through tutorials but they all seem to use maths to control the positioning, but I think it’s probably unnecessarily complicated for what I want to do. I have a number of shapes which I want to rotate around a single point.

This is what I have so far:

triangle1_mc.addEventListener(Event.ENTER_FRAME, rotateMovieClip);

function rotateMovieClip(e:Event)
{
    e.target.rotation += 0.5;
}

This causes the triangle to rotate around it’s centre. How would I tell it to rotate around the following point?
x 164.8
y 161.1

Thanks for your help!
