Interactively moving a game object in a circle

[anon78207325]

I would like to be able to constrain character movement to a circle around another game object. How do I consrain my game object to a certain radius yet let the player control the movement of the object around the center?

If I understand you right, you are looking for something like this:

var rotation : Quaternion;
var radius = Vector3(5,0,0);
var currentRotation = 0.0;
function Update()
{
    currentRotation += Input.GetAxis("Horizontal")*Time.deltaTime*100;
    rotation.eulerAngles = Vector3(0, currentRotation, 0);
    transform.position = rotation * radius;
}
