【问题描述】：

我正在使用 Microsoft MRTK v2.0.3，我正在尝试将空间感知添加到我的项目中，但是当我选择空间感知配置文件时，我不断收到以下错误：

Unable to register IMixedRealitySpatialAwarenessObserver service with a null concrete type.
UnityEngine.Debug:LogError(Object)

当我尝试在设备上进行模拟时，没有收集到有关周围环境的数据。我已激活空间感知和 VR 支持。

【问题讨论】：

MRTK 的最新版本是 2.3，此版本提供了新功能并修复了一些已知错误。作为测试，我们建议您先备份您的项目，然后按照此文档将 MRTK 升级到最新版本：microsoft.github.io/MixedRealityToolkit-Unity/version/releases/…

【解决方案1】：

通过查看 MixedRealityToolkit 中的所有配置文件（游戏对象及其同名脚本），我解决了相同的问题（以及其他几个同类问题）。请注意指示无法找到某些组件的红色标记字段。

在这种特殊情况下，查看“空间意识”组内部，复制现有配置文件并使用红色输入字段旁边的尝试修复。如果这不起作用，请手动搜索 WindowsMixedRealitySpatialMeshObserver。

我希望这对你也有帮助。
