This code is a demo for the rotator class that enables actors to rotate around a specific point on screen. In this demo, the robot rotates around a ball that can be dragged anywhere.
Source code is avilable, along with a fairly detailed commentary of the maths behind the positioning, so if you're interested in how it's done you should be able to follow - nothing hideously complicated though you do need to use the sine rule.
I've felt the need for a method like this in a few scenarios so if others have as well, hope this helps.
