如何为iOS和Android配置MRTK [实验性]

安装必需的软件包

  1. 从以下位置下载并导入Microsoft.MixedReality.Toolkit.Providers.UnityAR 程序包, 从 GitHub 或 NuGet

[!注意] 导入UnityAR程序包后，您将看到以下错误: Assembly has reference to non-existent assembly 'Unity.XR.ARFoundation' (Assets/MixedRealityToolkit.Staging/UnityAR/Microsoft.MixedReality.Toolkit.Providers.UnityAR.asmdef) . 要解决，请安装下面列出的正确版本的ARFoundation。

  1. 在Unity软件包管理器（UPM）中，安装以下软件包:

    Unity 2018.4.x

    Android iOS 评论
    AR Foundation
    版本: 1.5.0 - preview 6    		 AR Foundation
    版本: 1.5.0 - preview 6    		 对于Unity 2018.4，此软件包包含在预览中。要查看软件包：Window > Package Manager > Advanced > Show Preview Packages
    ARCore XR Plugin
    版本: 2.1.2    		 ARKit XR Plugin
    版本: 2.1.2

    Unity 2019.x

    Android iOS
    AR Foundation
    版本: 2.1.4    		 AR Foundation
    版本: 2.1.4
    ARCore XR Plugin
    版本: 2.1.2    		 ARKit XR Plugin
    版本: 2.1.2

  2. 如果使用Unity 2019.x，则需要修改Unity AR提供者的程序集定义文件以添加UnityEngine.SpatialTracking引用。

    [!注意] MRTK将根据项目加载的Unity版本自动更新程序集定义。此处提供此信息以供参考。

Building a Scene for Android and iOS devices

  1. Make sure you have added the UnityAR Camera Settings Provider to your scene.

  2. Switch platform to either Android or iOS in the Unity Build Settings

When you switch the platform you should see the MRTK Project Configurator Window with settings for your chosen platform. Click Apply to enable platform specific settings.

  1. There are no additional steps after switching the platform for Android.

  2. If the platform is iOS, Edit > Project Settings > Player > Other Settings, under the Optimization header, uncheck Strip Engine Code

Note

Unchecking Strip Engine Code is the short term solution to an error in Xcode #6646. We are working on a long term solution for MRTK 2.3.0.

  1. Build and run the scene
