How to limit a mouse orbit rotations

Hey guys I have a question, I am using the default built in mouse orbit and I wonder if there is a way to limit the rotations
instead let the camera rotate 360. I want to limit it into 180 or 90 degree

Mouse Orbit rotations

``````var target : Transform;
var distance = 10.0;

var xSpeed = 250.0;
var ySpeed = 120.0;

var yMinLimit = -20;
var yMaxLimit = 80;

private var x = 0.0;
private var y = 0.0;

function Start () {
var angles = transform.eulerAngles;
x = angles.y;
y = angles.x;

// Make the rigid body not change rotation
if (rigidbody)
rigidbody.freezeRotation = true;
}

function LateUpdate () {
if (target) {
x += Input.GetAxis("Mouse X") * xSpeed * 0.02;
y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02;

y = ClampAngle(y, yMinLimit, yMaxLimit);

var rotation = Quaternion.Euler(y, x, 0);
var position = rotation * Vector3(0.0, 0.0, -distance) + target.position;

transform.rotation = rotation;
transform.position = position;
}
}

static function ClampAngle (angle : float, min : float, max : float) {
if (angle < -360)
angle += 360;
if (angle > 360)
angle -= 360;
return Mathf.Clamp (angle, min, max);
}
``````

You see how it already limits the y angle? See yMinLimit, yMaxLimit, and the Clamp angle call in LateUpdate. Just do the same for the x angle as well.

Thanks SteveK,

I can’t believe it that I was trying to limit x values and just didn’t try this. Instead of this I was trying to write code from scratch and the limiting the values by myself. Thanks again for throwing light over this.
