so in my game i have a local co-op and i want a single camera to follow the players. this camera should be at a specified distance from the players but zoom in or zoom out, smoothly based on the distance between the two players like most old coop games. i have attempted to make it but it does not really work. can anyone suggest how to fix what i have or a whole new way of doing it. any help appreciated.

public class CameraFollow : MonoBehaviour

{

```
public Vector3 distance;
public Transform target1;
public Transform target2;
public float CamZPosition;
public float TargetZmiddle;
public float camDistance;
public float trial;
// Use this for initialization
void Start ()
{
}
// Update is called once per frame
void Update ()
{
distance = target1.position - target2.position;
TargetZmiddle = ((target1.position.z * target2.position.z) /2);
if(distance.x < 0)
distance.x = distance.x * -1;
if(distance.z < 0)
distance.z = distance.z * -1;
trial = camDistance + distance.x;
if(distance.z > 20)
{
//camDistance = trial;
}
if(distance.x > 20)
{
camDistance = trial;
}
if(distance.x < 19 || distance.z < 19)
{
camDistance = 10;
}
//Debug.Log (TargetZmiddle);
transform.position = new Vector3(transform.position.x, transform.position.y, (TargetZmiddle - camDistance));
}
```

}

for anyone that wants to know i have completed this function

the final code is below

using UnityEngine;

using System.Collections;

using System.Collections.Generic;

public class CameraFollow : MonoBehaviour

}
}
```

hellp hi bro i want use this script but is not working
