Scope wont zoom in

Unity Engine
1

Hello, I am trying to make a scope for a gun, and have it zoom in a little bit… I have the variable “zoomangle” but it doesn’t seem to even acknowledge it. Here is my code for the
Gun:

var cameraObject : GameObject;
@HideInInspector
var targetXRotation : float;
@HideInInspector
var targetYRotation : float;
@HideInInspector
var targetXRotationV : float;
@HideInInspector
var targetYRotationV : float;

var rotateSpeed : float = 0.3;

var holdHeight : float = -0.5;
var holdSide : float = 0.5;
var racioHipHold : float = 1;
var hipToAimSpeed : float = 0.1;
@HideInInspector
var racioHipHoldV : float;

var aimRacio : float = 0.4;

var zoomAngle : float = 30;

function Update () 
{
    cameraObject.GetComponent(MouseLookScript).current  TargetCameraAngle = zoomAngle;
    
    if (Input.GetButton("Fire2")){
        cameraObject.GetComponent(MouseLookScript).currentAimRacio = aimRacio;
        racioHipHold = Mathf.SmoothDamp(racioHipHold, 0, racioHipHoldV, hipToAimSpeed);}
    if (Input.GetButton("Fire2") == false){
        cameraObject.GetComponent(MouseLookScript).currentAimRacio = 1;
        racioHipHold = Mathf.SmoothDamp(racioHipHold, 1, racioHipHoldV, hipToAimSpeed);}
    
    transform.position = cameraObject.transform.position + (Quaternion.Euler(0,targetYRotation,0) * Vector3(holdSide * racioHipHold, holdHeight * racioHipHold, 0));
    
    targetXRotation = Mathf.SmoothDamp( targetXRotation, cameraObject.GetComponent(MouseLookScript).xRotation, targetXRotationV, rotateSpeed);
    targetYRotation = Mathf.SmoothDamp( targetYRotation, cameraObject.GetComponent(MouseLookScript).yRotation, targetYRotationV, rotateSpeed);
    
    transform.rotation = Quaternion.Euler(targetXRotation, targetYRotation, 0);
}

and camera

var defaultCameraAngle : float = 60;
@HideInInspector
var currentTargetCameraAngle : float = 60;
@HideInInspector
var racioZoom : float = 1;
@HideInInspector
var racioZoomV : float;
var racioZoomSpeed : float = 0.2;
 
var lookSensitivity : float = 5;
@HideInInspector
var yRotation : float;
@HideInInspector
var xRotation : float;
@HideInInspector
var currentYRotation : float;
@HideInInspector
var currentXRotation : float;
@HideInInspector
var yRotationV : float;
@HideInInspector
var xRotationV : float;
var lookSmoothDamp : float = 0.1;
@HideInInspector
var currentAimRacio : float = 1;
 
function Update () 
{
    if (currentAimRacio == 1)
        racioZoom = Mathf.SmoothDamp(racioZoom, 1, racioZoomV, racioZoomSpeed);
    else
        racioZoom = Mathf.SmoothDamp(racioZoom, 0, racioZoomV, racioZoomSpeed);
        
    camera.fieldOfView = Mathf.Lerp(currentTargetCameraAngle, defaultCameraAngle, racioZoom);
 
    yRotation += Input.GetAxis("Mouse X") * lookSensitivity * currentAimRacio;
    xRotation -= Input.GetAxis("Mouse Y") * lookSensitivity * currentAimRacio;
    
    xRotation = Mathf.Clamp(xRotation, -90, 90);
    
    currentXRotation = Mathf.SmoothDamp(currentXRotation, xRotation, xRotationV, lookSmoothDamp);
    currentYRotation = Mathf.SmoothDamp(currentYRotation, yRotation, yRotationV, lookSmoothDamp);
    
    transform.rotation = Quaternion.Euler(currentXRotation, currentYRotation, 0);
}

Does this work? (the new gun script)

“Assets/Gunscript.js(26,55): UCE0001: ‘;’ expected. instert a semicolon at the end.”
I’ve been getting this error and I’m irritated as hell… THERE IS ALREADY A FRAKKING SEMI-COLON!

4

As far as I’m concerned, that error may as well read: “There is something wrong with this line. Fix it.”

Anyways, you left a space at this line between current and TargetCameraAngle.

5

OHHHHHHHHHHHHHHHHHHHHHHHHHHHHH! ok that makes sense now…

Thank you!

6

Now I have another problem… It zooms in but it takes a while to zoom back out… Also, I cannot move while aiming… (that could be because of a variable I have set, I’ll check)

EDIT
Just checked, Nope, no clue why I can’t aim while aiming…

7

Do you mean it smoothly goes back out? In that case, just lower your “hipToAimSpeed” variable.

8

No, I let go of right click and it takes a while before it zooms out… when it does, it does it at a regular rate. But it takes a while for it to happen

What about (for the camera)

    var defaultCameraAngle : float = 60;
    @HideInInspector
    var currentTargetCameraAngle : float = 60;
    @HideInInspector
    var racioZoom : float = 1;
    @HideInInspector
    var racioZoomV : float;
    var racioZoomSpeed : float = 0.2;
     
    var lookSensitivity : float = 5;
    @HideInInspector
    var yRotation : float;
    @HideInInspector
    var xRotation : float;
    @HideInInspector
    var currentYRotation : float;
    @HideInInspector
    var currentXRotation : float;
    @HideInInspector
    var yRotationV : float;
    @HideInInspector
    var xRotationV : float;
    var lookSmoothDamp : float = 0.1;
    @HideInInspector
    var currentAimRacio : float = 1;
     
    function Update ()
    {
       
        racioZoom = Mathf.SmoothDamp(racioZoom, currentAimRacio , racioZoomV, racioZoomSpeed);
           
        camera.fieldOfView = Mathf.Lerp(currentTargetCameraAngle, defaultCameraAngle, racioZoom);
     
        yRotation += Input.GetAxis("Mouse X") * lookSensitivity * currentAimRacio;
        xRotation -= Input.GetAxis("Mouse Y") * lookSensitivity * currentAimRacio;
       
        xRotation = Mathf.Clamp(xRotation, -90, 90);
       
        currentXRotation = Mathf.SmoothDamp(currentXRotation, xRotation, xRotationV, lookSmoothDamp);
        currentYRotation = Mathf.SmoothDamp(currentYRotation, yRotation, yRotationV, lookSmoothDamp);
       
        transform.rotation = Quaternion.Euler(currentXRotation, currentYRotation, 0);
    }

Nope, still can’t aim while zoomed…

11

what is ‘racio’?

Is that supposed to be ‘ratio’? as in a %?

12

It’s a mistake in Eteeski’s tutorials that everyone looked funny at, said “meh, maybe it was spelled like that for a reason” and moved on.

What do you mean by can’t aim? Can’t turn? Can’t zoom out? No ADS?

13

As in can’t turn… Sorry for not specifying xP

            camera.fieldOfView = Mathf.Lerp(currentTargetCameraAngle, defaultCameraAngle, racioZoom);
         
            yRotation += Input.GetAxis("Mouse X") * lookSensitivity;
            xRotation -= Input.GetAxis("Mouse Y") * lookSensitivity;
           
            xRotation = Mathf.Clamp(xRotation, -90, 90);
           
            currentXRotation = Mathf.SmoothDamp(currentXRotation, xRotation, xRotationV, lookSmoothDamp);
            currentYRotation = Mathf.SmoothDamp(currentYRotation, yRotation, yRotationV, lookSmoothDamp);
           
            transform.rotation = Quaternion.Euler(currentXRotation, currentYRotation, 0);
        }

Just to let you know, I have to do a lot of guessing, as I don’t have the game in front of me. Anyways, try this camera script.

Works great! THANKS!

Glad to hear that! :slight_smile:
