error CS0619: 'XRDevice.isPresent' is obsolete: 'This is obsolete, and should no longer be used. Instead, find the active XRDisplaySubsystem and check that the running property is true (for details, see XRDevice.isPresent documentation).'
因为在2017版本后unity.Engine.VR就过时了，换成了XR，所以我们需要对一些项目维护进行对应的更改。网上查了很多资料，基本没有确切对应的解决方案，于是使用leap motion官方升级文档对比查看，解决方案如下：
public static bool IsXRDevicePresent() {
#if UNITY_2020_1_OR_NEWER
return XRSettings.isDeviceActive;
#elif UNITY_2017_2_OR_NEWER
return XRDevice.isPresent;
#else
return VRDevice.isPresent;
#endif
}
我们可以直接使用XRSettings.isDeviceActive代替XRDevice.isPresent。
对应版本同上。
附所有有关XR的过时报错更改：对照上述参考
