Unity 3D如何找到实例化隐藏组件的游戏对象

Question

我有一个与Photon Unity Network（PUN）和Photon Audio一起运行的多用户应用程序。 使用光子音频，音频将流传输到PUN服务器，然后发送到游戏中的所有玩家。 Photon Audio在Unity核心音频类之上具有包装器类，以进行流传输。

我正在使用该论坛的Photon-Voice论坛中的指南，该指南说，要记录完整的应用程序输出混合，如果在具有AudioListener的对象上实现，则可以使用MonoBehaviour.OnAudioFilterRead。

问题是我找不到已经创建AudioListener实例的游戏对象，所以我无法使用AudioListener创建自己的游戏对象，因为它作为第二个实例出现。

我尝试使用：

var foundObjects = FindObjectsOfType<AudioListener>();
Debug.Log("**** " + foundObjects + " : " + foundObjects.Length)

它返回说有一个AudioListener的活动实例：

任何有关如何找到实例化AudioListener的游戏对象的帮助将不胜感激。

更新1： AudioListener可能由场景中的唯一摄像机实例化，并且该摄像机可能来自我正在使用的名为InstantVR的外部库。 但是，它的发生与AudioListener组件相同：我找不到实例化摄像机的脚本。 使用var cam = FindObjectOfType<Camera>(); 我得到： Headcam (UnityEngine.Camera) : Headcam

Answer 1

在我正在调试的应用程序中， [HideInInspector] ， HideFlags.HideInHierarchy和HideFlags.HideInInspector适用于第三方库中的某些游戏对象和组件。

我使用以下代码找到了所需的游戏对象和组件，并在应用程序运行时检查了层次结构和检查器：

void Update()
{
    if (Input.GetKeyDown(KeyCode.Space))
    {
        GameObject[] foundObjects = FindObjectsOfType<GameObject>();
        Debug.Log("**** " + foundObjects + " : " + foundObjects.Length);
        var count = 0;
        if (foundObjects != null)
        {
            foreach (GameObject foundObject in foundObjects)
            {
                count++;
                if (foundObject.hideFlags == HideFlags.HideInHierarchy || foundObject.hideFlags == HideFlags.HideInInspector)
                {
                    foundObject.hideFlags = HideFlags.None;
                    Debug.Log("**** foundObject: " + foundObject + " : foundObject Name: " + foundObject.name + " - Count: " + count);
                }
            }
        }
    }
}

然后可以从层次结构访问隐藏的对象。 希望它可以帮助别人。
