# How to use this Camera

I have this code,but i don't know what to do with him.... Does i need to put java scrript in main camera or what??? Help pleaseeeeeee :(

``````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;

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

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

function LateUpdate () {

if (target) {

if(Input.GetKey("mouse 1")){
Screen.showCursor = false;
x += Input.GetAxis("Mouse X") * xSpeed * distance* 0.02;
y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02;
}else{
Screen.showCursor = true;
}
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);
}`

Yes, you put it on the main camera, and then drag the object you want to look at into the target variable in the inspector for the script
