Question Need help making switch shoulders script

Hi everyone. This is my first time posting here and I've been needing help quite some time now. I'm making a game and I want to add a feature that when I press V, it switches shoulders. I'm kinda new to Unity so don't mind teaching me new stuff.

I wanted to make a script that allows me to switch camera side from the CineMachineVirtualCamera component:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.InputSystem;
3.  
4. public class CameraSideChanger : MonoBehaviour
5. {
6.     public Cinemachine.CinemachineVirtualCamera virtualCamera;
7.     private float currentXPosition;
8.  
9.     private void Start()
10.     {
11.         currentXPosition = 0f;
12.     }
13.  
14.     private void Update()
15.     {
16.         if (Keyboard.current.vKey.wasPressedThisFrame)
17.         {
18.             currentXPosition = (currentXPosition == -0.6f) ? 0.6f : -0.6f;
19.             UpdateCameraXPosition();
20.         }
21.     }
22.  
23.     private void UpdateCameraXPosition()
24.     {
25.         Cinemachine.CinemachineTransposer transposer = virtualCamera.GetCinemachineComponent<Cinemachine.CinemachineTransposer>();
26.         if (transposer != null)
27.         {
28.             Vector3 newPosition = transposer.m_FollowOffset;
29.             newPosition.x = currentXPosition;
30.             transposer.m_FollowOffset = newPosition;
31.         }
32.     }
33. }
34.  

It's meant to change this value:


I've attached it into an empty gameobject and that's it.


Please help!!!

 

I think you want to have two virtual cams, one for each shoulder, then tell Cinemachine to switch smoothly between them.

There's also a dedicated cinemachine forum: https://forum.unity.com/forums/cinemachine.136/

OR if you want to do the tweening yourself, then use Vector3.Lerp and your "camera side" variable to generate a position between the two shoulder positions.

If you need it to arc up and over the head, you would need some kind of path specification mechanism such as a bezier curve going from shoulder to shoulder, and use that to tween.

Smoothing any scalar value between any two particular values:

https://forum.unity.com/threads/beginner-need-help-with-smoothdamp.988959/#post-6430100

You have currentQuantity and desiredQuantity.
- only set desiredQuantity
- the code always moves currentQuantity towards desiredQuantity
- read currentQuantity for the smoothed value

Works for floats, Vectors, Colors, Quaternions, anything continuous or lerp-able.

The code: https://gist.github.com/kurtdekker/fb3c33ec6911a1d9bfcb23e9f62adac4

Another approach would be to use a tweening package such as LeanTween, DOTween or iTween.

OR... just make a simple canned animation... No code needed!

For score count-up (like a cash register whizzing lots of numbers upwards), I like this approach:

Here's a video tutorial for it with two different approaches to switching (state-based and code-based). Code is the easiest if you're not expecting to have many cameras as you're just adjusting the priority of the cameras.

 

Thanks guys. Both of you.
