Description

Improved version of the original MouseOrbit script. Zooms with the mousewheel and uses linecast to make sure that object isn't behind anything.

Feel free to improve it further!

Code Javascript

var target : Transform;
var distance = 10.0;
 
var xSpeed = 250.0;
var ySpeed = 120.0;
 
var yMinLimit = -20;
var yMaxLimit = 80;
 
var distanceMin = 3;
var distanceMax = 15;
 
private var x = 0.0;
private var y = 0.0;
 
 
@script AddComponentMenu("Camera-Control/Mouse Orbit")
 
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 * distance* 0.02;
        y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02;
 
 		y = ClampAngle(y, yMinLimit, yMaxLimit);
 
		var rotation = Quaternion.Euler(y, x, 0);
 
		distance = Mathf.Clamp(distance - Input.GetAxis("Mouse ScrollWheel")*5, distanceMin, distanceMax);
 
		var hit : RaycastHit;
		if (Physics.Linecast (target.position, transform.position, hit)) {
				distance -=  hit.distance;
		}
 
        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);
}
