Camera by tag!

i have a camera follow code. how can i get this code to follow the object by the tag instead of choosing the object itself?

My Code:


var target : Transform;
var distance = 3.0;
var height = 3.0;
var damping = 5.0;
var smoothRotation = true;
var rotationDamping = 10.0;

function Update () {
var wantedPosition = target.TransformPoint(0, height, -distance);
transform.position = Vector3.Lerp (transform.position, wantedPosition, Time.deltaTime * damping);

if (smoothRotation) {
var wantedRotation = Quaternion.LookRotation(target.position - transform.position, target.up);
transform.rotation = Quaternion.Slerp (transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
}

else transform.LookAt (target, target.up);
}

 

Add var objTag : String or any other variable for your tag variable. Under Update function add target = GameObject.FindWithTag(objTag).transform;. That's it, now every time you change objTag to a object tag camera will fallow object with that tag.

Like this:

var target : Transform;
var distance = 3.0;
var height = 3.0;
var damping = 5.0;
var smoothRotation = true;
var rotationDamping = 10.0;
var objTag : String;

function Update () {
target = GameObject.FindWithTag(objTag).transform;
var wantedPosition = target.TransformPoint(0, height, -distance);
transform.position = Vector3.Lerp (transform.position, wantedPosition, Time.deltaTime * damping);

if (smoothRotation) {
var wantedRotation = Quaternion.LookRotation(target.position - transform.position, target.up);
transform.rotation = Quaternion.Slerp (transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
}

else transform.LookAt (target, target.up);
}

 

thanx testing that now!
