Unable to serialize field for CinemachineVirtualCamera

[pjk]

Finally hit my first snag of the course while trying to apply zoom to the Cinemachine Virtual Camera. Feels like it ought to be a simple fix but I can’t quite figure it out.

I’m using this code directly from the lesson video:

[SerializeField] private CinemachineVirtualCamera cinemachineVirtualCamera;

Visual Studio throws an error for the [SerializeField] portion and tells me that “attributes are not valid in this context,” and it throws an error for the private attribute as well.

I’m on Unity 2022.2.0a17.2573, using the 2.9.0-pre.6 version of Cinemachine from the Package Manager.

Can you post your entire code?
Sounds like perhaps you have a extra { or } somewhere
Or maybe you’re trying to define that while inside a function?

Sure. Here’s my full code for CameraController.cs:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Cinemachine;

public class CameraController : MonoBehaviour
{
    private void Update()
    {

        [SerializeField] private CinemachineVirtualCamera cinemachineVirtualCamera;

        // Movement
        Vector3 inputMoveDir = new Vector3(0, 0, 0);
        if (Input.GetKey(KeyCode.W))
        {
            inputMoveDir.z = +1f;
        }
        if (Input.GetKey(KeyCode.S))
        {
            inputMoveDir.z = -1f;
        }
        if (Input.GetKey(KeyCode.A))
        {
            inputMoveDir.x = -1f;
        }
        if (Input.GetKey(KeyCode.D))
        {
            inputMoveDir.x = +1f;
        }

        float moveSpeed = 10f;

        Vector3 moveVector = transform.forward * inputMoveDir.z + transform.right * inputMoveDir.x;
        transform.position += moveVector * moveSpeed * Time.deltaTime;


        // Rotation
        float rotationSpeed = 100f;

        Vector3 rotationVector = new Vector3(0, 0, 0);

        if (Input.GetKey(KeyCode.Q))
        {
            rotationVector.y = +1f;
        }
        if (Input.GetKey(KeyCode.E))
        {
            rotationVector.y = -1f;
        }

        transform.eulerAngles += rotationVector * rotationSpeed * Time.deltaTime;

        // Zoom

        Debug.Log(Input.mouseScrollDelta);

        CinemachineTransposer cinemachineTransposer = cinemachineVirtualCamera.GetCinemachineComponent<CinemachineTransposer>();

        if (Input.mouseScrollDelta.y > 0)
        {
            cinemachineTransposer.m_FollowOffset = new Vector3(0, 1, -10);
        }
    }
}

You were exactly right - looks like I was trying to serialize the camera inside the Update() method instead of before it. Thanks!
