联合基金会找不到ARCameraBackground

unity3d android c#

除了从我的移动设备实际获取摄像头提要外,其他一切都正常,运行内置编辑器会返回错误:

NullReferenceException: Object reference not set to an instance of an object
UnityEngine.XR.ARFoundation.ARCameraBackground.OnDisable () (at Library/PackageCache/com.unity.xr.arfoundation@2.2.0-preview.2/Runtime/AR/ARCameraBackground.cs:192)

我已经查看了它声称有错误的脚本,错误似乎源自此块:

void OnEnable()
        {
            UpdateMaterial();
            m_CameraManager.frameReceived += OnCameraFrameReceived;
            ARSession.stateChanged += OnSessionStateChanged;
        }

void OnDisable()
        {
            mode = ARRenderMode.StandardBackground;
            m_CameraManager.frameReceived -= OnCameraFrameReceived;
            ARSession.stateChanged -= OnSessionStateChanged;
            m_CameraSetupThrewException = false;

            // We are no longer setting the projection matrix
            // so tell the camera to resume its normal projection
            // matrix calculations.
            m_Camera.ResetProjectionMatrix();
        }

我正在努力弄清楚为什么AR基金会不能确定摄像头的来源,我已经做了相当多的谷歌搜索到这个问题。当试图在设备上运行它时,它会请求摄像头的许可,但是提要从不显示。
