I have drones in my game that need to approach and orbit a node and shoot at it. Problem is I want to stay away from a real physics simulation, meaning I don't want to give the node and drone a mass and the drone's thrusters' a force. I just want to find the best way to approach and then enter orbit. There was a pretty good answer about using bezier curves and doing it that way, but that is essentially a tween between two fixed points. The nodes are also moving as the drones enter orbit.
