Cursor Return to Player?

I have a sidekick (shane) controlled by the right analogue stick:


_Shane.Physics.VelocityX = move.Sticks[1].X * 55.0f;
_Shane.Physics.VelocityY = -move.Sticks[1].Y * 55.0f;

I want this character to move towards the main player when the right analogue stick isn't moving but want to be able to control it when the right stick is. A self-centreing sidekick so to speak.

I know the code to send him back to the main character (vic):


_Shane.Physics.Velocity = T2DVectorUtil.VelocityFromTarget(_Shane.Position,
_Vic.Position, 10);

but don't know how to check to see if the stick is being moved. Any help gratefully appreciated.
