Mouse Look Script Help
Hello all! I was wondering if someone could explain this Mouse Look script inside-out for me. I just want to know exactly how it works, rather than just copying and pasting it, or dragging and dropping it. Much thanks in advance! (Note: I found this script online, and I do NOT think it is the same as the default Unity one. But it still works.)
Here's the script:
@script AddComponentMenu ("Camera-Control/Mouse Look") enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 } var axes = RotationAxes.MouseXAndY; var sensitivityX : float = 15; var sensitivityY : float = 15;
var minimumX : float = -360; var maximumX : float = 360;
var minimumY : float = -60; var maximumY : float = 60;
var rotationX : float = 0; var rotationY : float = 0;
private var originalRotation : Quaternion;
function Update () { if (axes == RotationAxes.MouseXAndY) { rotationX += Input.GetAxis("Mouse X") sensitivityX; rotationY += Input.GetAxis("Mouse Y") sensitivityY;
rotationX = ClampAngle (rotationX, minimumX, maximumX);
rotationY = ClampAngle (rotationY, minimumY, maximumY);
var xQuaternion = Quaternion.AngleAxis (rotationX, Vector3.up);
var yQuaternion = Quaternion.AngleAxis (rotationY, Vector3.left);
transform.localRotation = originalRotation * xQuaternion * yQuaternion;
}
else if (axes == RotationAxes.MouseX) {
rotationX += Input.GetAxis("Mouse X") * sensitivityX;
rotationX = ClampAngle (rotationX, minimumX, maximumX);
xQuaternion = Quaternion.AngleAxis (rotationX, Vector3.up);
transform.localRotation = originalRotation * xQuaternion;
}
else {
rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
rotationY = ClampAngle (rotationY, minimumY, maximumY);
yQuaternion = Quaternion.AngleAxis (rotationY, Vector3.left);
transform.localRotation = originalRotation * yQuaternion;
}
}
function Start () { if (rigidbody) rigidbody.freezeRotation = true; originalRotation = transform.localRotation; }
static function ClampAngle (angle : float, min : float, max : float) : float { if (angle < -360.0) angle += 360.0; if (angle > 360.0) angle -= 360.0; return Mathf.Clamp (angle, min, max);
}
