Hello,

I'm working in this Robot-Toy, I am trying to fix the rotation of the arm, but the Arm rotates keeping the same orientation don't change (always see to the same direction).

(The Base's Arm (in color green) rotates well, but the Arm as a "children" rotates keeping the same orientation)

Please take a look to the image.

Here it is the Script I am using for the base in green color.

var gunSpeedNeg: int = -40;
var gunSpeedPos: int = 40;
function Update () {


    if(Input.GetKey("r")){
    transform.Rotate(Vector3.right* gunSpeedNeg* Time.deltaTime);

                        }
    if(Input.GetKey("y")){
    transform.Rotate(Vector3.right* gunSpeedPos* Time.deltaTime);
                        }

    }

And here it is the script for the arm " who has to rotate according to the arm but it doesn't (It rotates but always keeping the same orientation)

var gunSpeed : float = 40;

private var rotation : Quaternion = Quaternion.identity;
private var left : Quaternion = Quaternion.AngleAxis(-150, Vector3.up);
private var right : Quaternion = Quaternion.AngleAxis(30, Vector3.up);

function Start ()
{
    // This piece of code will allow you to remember the origin.
    rotation = transform.rotation;
    left = rotation * left;
    right = rotation * right;
}

function Update () 
{
    var speed = gunSpeed * Time.deltaTime;

    if(Input.GetKey("a"))
    {
        rotation = Quaternion.RotateTowards(rotation, left, speed);
    }

    if(Input.GetKey("d"))
    {
        rotation = Quaternion.RotateTowards(rotation, right, speed);
    }

    transform.rotation = rotation;
}

Any advice is welcome.
