Increase camera Zoom

Hello guys, I have this script which zoom the camera to a field of view of 1, But its not enough for my scene. My scene is huge. How Do I make the camera to zoom to a longer distance.

My script is below,

    var zoom : int = 20;
    var normal : int = 60;
    var smooth : float = 5;
    private var isZoomed = false;
    function Update () {
    //if(Input.GetKey("z")){
	if(Input.GetAxis("Mouse ScrollWheel")){
    isZoomed = !isZoomed;
    }
     
    if(isZoomed == true){
    camera.fieldOfView = Mathf.Lerp(camera.fieldOfView,zoom,Time.deltaTime*smooth);
    }
    else{
    camera.fieldOfView = Mathf.Lerp(camera.fieldOfView,normal,Time.deltaTime*smooth);
    }
    }

Here you can find many “famous” camera script : Scripts/Controllers
In particular i suggest you to adopt MouseOrbitZoom without the orbit part if you don’t want it:

public Transform target;
public float distance = 10f;
public float maxDistance = 100;
public float minDistance = 5f;
public int zoomRate = 40;
public float zoomDampening = 5.0f;
private float currentDistance;
private float desiredDistance;
private Vector3 position;

public void Start(){
     if (!target){
        var go = new GameObject("Cam Target");
        go.transform.position = transform.position + (transform.forward * distance);
        target = go.transform;
    }

    currentDistance = distance;
    desiredDistance = distance;
    position = transform.position;
}

public void LateUpdate(){
    // scrollwheel affect the desired ZOOM distance
    desiredDistance -= Input.GetAxis("Mouse ScrollWheel") * Time.deltaTime * zoomRate * Mathf.Abs(desiredDistance);
    //clamp the zoom min/max
    desiredDistance = Mathf.Clamp(desiredDistance, minDistance, maxDistance);
    // For smoothing of the zoom, optional
    currentDistance = Mathf.Lerp(currentDistance, desiredDistance, Time.deltaTime * zoomDampening);

    // calculate position based on the new currentDistance
    position = target.position - (Vector3.forward * currentDistance);
    transform.position = position;
}

in the ispector you can modify the zoom rate, min and in particular max :slight_smile:
