How to install RTT4U¶

To use Real Time Testing for Unity (hereinafter referred to as RTT4U), you need to prepare as follows.

1. Set up development environment¶

You need to configure the following development environment to use RTT4U.

• Windows 10 or macOS 14.3 or higher
• Unity Editor 2021 or higher (macOS: Apple Silicon Unity Editors)
• Android SDK Command-line Tools 6.0
• Android Target SDK 33
• OpenJDK 11.0.18
• Hive SDK v4 Unity 24.3.0 or higher

RTT4U is currently available for Android only. Therefore, change the platform to Android target in File > Build Settings before using it.

2. Download and import RTT4U¶

Download RTT4U from here and import it into your Unity project.

3. Install Unity Android Build Support¶

Check all components of Android Build Support during Unity installation and install them.

4. Install Android Studio and command-line tools (Windows)¶

In the Windows development environment, you cannot create system images within the Android SDK folder created during Unity installation due to administrator permission issues. Therefore, follow the steps below to install Android Studio and the command-line tools.

4.1. Install Android Studio¶

Download Android Studio from here. The Android SDK installation path is \Users\your_account\AppData\Local\Android\sdk.

4.2. Install Android command-line tools¶

After installing Android Studio, create a blank project. In the Android Studio project screen, click SDK Manager, then install Android SDK Command-line Tools 6.0 from SDK Tools > Android SDK Command-line Tools (latest).

5. Check environment variables¶

Check whether the Java environment variable is set. Enter java -version in the terminal; if the Java version is displayed, it is correctly set.

6. Enter Android SDK Path¶

Enter the path where the Android SDK is installed in Android SDK Path.

7. Install Android system image¶

After running Unity, click Hive > RTT4U > RTT Player Settings from the top menu.

In the RTT Player Settings popup, click Download Android System-Image to install the emulator system image.

The system image will be installed in the paths below depending on the development environment. RTT4U will only operate correctly if installed in the exact path, so you must check the installation results.

• Windows: Android SDK path/system-images/android-XX/google_apis_playstore/x86_64
• MacOS: Android SDK path/system-images/android-XX/google_apis_playstore/arm64-v8a

8. Create RTT Player¶

If you have installed the emulator system image, click Create RTT Player to create the RTT Player. The RTT Player is an emulator for testing Hive SDK functionality.

9. Enter Start Scene¶

Enter the Scene that starts the app in Start Scene. The Scene that starts the app is the Scene where Hive SDK Unity Plugin initialization (HIVEUnityPlugin.InitPlugin) is executed. After entering, click Save settings to save the configuration.

10. Test RTT Player execution¶

After creating the RTT Player, click Run the RTT Player to check if the emulator is functioning properly.
