Hi all

Have a look at the attachment.

I have a circle menu and i want to do something with it, but i need to find the specific amount of movement on each axes.

I do not know how to do this.

If there is a point on a circle at 0 degrees and radius 200 px in width and there is another point 10 degrees away with the same radius, then how can i find out from these values how much the x and y position moved in that rotation?

The drawing is more usful than me trying to explain it but thanks for giving it a go!

Cheers,

Clark
