Basically i wanna know how you can click a moving circle to cause a program to stop. Ideally anywhere inside the circle. Cheers

Presuming you know the co-ordinates of the center of the circle I'd do something like this:

If Sqrt(((MouseX() - [Center of circle (x)])^2) + ((MouseY() - [Center of circle (y)])^2)) <= [Radius of circle] then ...etc...

We rode on the winds of the rising storm, we ran to the sounds of the thunder.
We danced among the ligtning bolts, and tore the world asunder.

Cheers for that, it works a treat. But what does the ^ do? I've never used or seen it been used before.
