Help with Lerp

Hello!

I want my gun to follow smoothly the FPS camera. I tried to use Lerp but I don't get how it is used... any help?

this is what I tried:k

 var gun : GameObject;
 var target : GameObject;
 
 function Start() {
 
 }
 
 function Update() {
 transform.position = Vector3.Lerp(gun.transform.position, target.position, Time.deltaTime);
 }

It should be on your gun, yes. I don't see anything wrong with the script for it to not work. Does your gun move at all? You could apply a speed to it for it to move faster. And also, if your camera is rotating about, which I assume it is, you probably need to follow with rotation as well as position.

 #pragma strict
 
 var target : GameObject;
 var speed : float = 2;
 
 function Start () {
 
 }
 
 function Update () {
 
     transform.position = Vector3.Lerp(transform.position, target.transform.position, Time.deltaTime * speed );
     transform.rotation = Quaternion.Slerp(transform.rotation, target.transform.rotation, Time.deltaTime * speed );
 }

Just a note: if the script is attached to your gun, you don't need to have a variable to access the GameObject, you can simply use "gameObject" to access the GameObject your script is attached to, or "transform" to access your GameObject's transform, like above.
