   • x64 and x86

Integration guide

1. Download the ONE Game Hosting Plugin from the Unreal Marketplace.

2. Copy the plugin folder into C:\Program Files\Epic Games\UE_4.26\Engine\Plugins.

3. In Unreal Engine Editor, go to Edit > Plugins menu.

4. Select the plugin from step 1 and click Enable.

5. Relaunch the Unreal Editor and open your game.

6. Click Add New > Blueprint Class and search for class One Arcus Server.

7. Drag in the new One Arcus Server into a persistent level, so that the One Arcus Server persist during the whole game life cycle.

8. Follow the next task: How to test below.

How to test

There are two ways to test a Game Server that is running an One Arcus Server:

1. The SDK contains a Fake Agent that can connect and simulate a real deployment. Build and run instructions can be found here.
2. The Game Server can be uploaded to a live One Development Platform Deployment.

Testing can be performed either in Unreal Engine Editor or on a build running in headless mode.

Package export

This is an optional step for developers that need to locally build and package the plugin.

Windows

1. Add C:\Program Files\Epic Games\UE_4.26\Engine\Build\BatchFiles in the PATH environment variable

2. Build the Arcus plugin:

   a. The one-gamehosting-sdk-unreal repository is cloned in the folder %USERPROFILE%/source/repos/one-gamehosting-sdk-unreal

   b. Run the following command to build the sdk plugin: (Where ... is the working directory where you want to copy the plugin.)

   RunUAT.bat BuildPlugin -plugin="%USERPROFILE%/source/repos/one-gamehosting-sdk-unreal/4.26/ONEGameHostingPlugin/ONEGameHostingPlugin.uplugin" -package="%USERPROFILE%/.../Plugins/ONEGameHostingPlugin"

   c. Copy the ONEGameHostingPlugin into Unreal Engine plugin directory: C:\Program Files\Epic Games\UE_4.26\Engine\Plugins\One, since it cannot be set directly through their toolchain.

Linux

1. Follow the Linux Quick Start for instructions on how to build the Unreal Engine locally.
2. For the following steps: the UnrealEngine is cloned in the folder ~/src/UnrealEngine/ and the one-gamehosting-sdk-unreal is cloned in the folder ~/src/one-gamehosting-sdk-unreal. Make sure that the folder is created ~/src/One.

3. Build the Arcus plugin and run the following command:

   ~/src/UnrealEngine/Engine/Build/BatchFiles/RunUAT.sh BuildPlugin -plugin=../one-gamehosting-sdk-unreal/4.26/ONEGameHostingPlugin/ONEGameHostingPlugin.uplugin -package=../One/ONEGameHostingPlugin -TargetPlatform=Linux

4. Copy the folder ~/src/One/ONEGameHostingPlugin in ~/src/UnrealEngine/Engine/Plugin/One/ONEGameHostingPlugin

For developers using this plugin

Optional - The target audience is software developers that want to build the plugin locally without using pre-built plugin from the Unreal Engine marketplace.
