This article describes how to integrate PlayFab Multiplayer Server SDK (GSDK) Unreal Online Subsystem (OSS) plugin with your Unreal project. This plugin offers both a Blueprint API and a C++ API. The Blueprint API still requires your Unreal Project to be a C++ project, and will not work on a Blueprint only project. If it is currently a Blueprint only project, then you need to convert to a C++ project beforehand, before adding the plugin. It has been originally tested with Unreal Engine 4.26, 4.27, 5.0 and, 5.1. This plugin will be actively maintained to work with the latest 3 - 4 versions of Unreal. If something fails using these versions, please open an issue here: [Unreal Engine GSDK Repo](https://github.com/PlayFab/gsdk/issues). To use these guides, replace all instances of **ThirdPersonMP** with your project name, if different. ## Requirements * Download Visual Studio. The [community version](https://visualstudio.microsoft.com/vs/community/) is free. * Required workloads: .NET desktop development and Desktop development with C++ * Download Unreal Engine Source Code. For instructions, see [Downloading Unreal Engine Source code (external)](https://docs.unrealengine.com/ProgrammingAndScripting/ProgrammingWithCPP/DownloadingSourceCode/). * If you haven't already, perform a git clone this repo to your local machine * `git clone https://github.com/PlayFab/gsdk.git` * Later steps will involve integrating files from this repo to your project * \[Optional] Download the [LocalMultiplayerAgent](https://github.com/PlayFab/MpsAgent/releases) * \[Optional] Alternatively, download [LocalMultiplayerAgent source](https://github.com/PlayFab/MpsAgent/tree/main/LocalMultiplayerAgent). * \[Optional] [PlayFab Marketplace plugin](https://www.unrealengine.com/marketplace/product/playfab-sdk) or the [source version on GitHub](https://github.com/PlayFab/UnrealMarketplacePlugin/tree/master/PlayFabPlugin/PlayFab). This plugin is not required for GSDK but is required for many PlayFab services, including login. ## Project creation The Unreal server project needs to be a network-enabled multiplayer Unreal project with a dedicated-server mode. If you don't have a project that meets these prerequisites, follow our [Unreal prerequisite set up guide](https://docs.xbox.com/services/playfab/multiplayer/servers/server-sdks/unreal-gsdk/third-person-mp-example-project-setup.md) to set one up. Once you have a network-enabled, multiplayer project, with a dedicated server, return to this step and continue. When ready, open your network-enabled multiplayer Unreal server project, and continue to the next step to install the Unreal GSDK. ## Project GSDK setup * GSDK Project Prerequisite details * Dedicated Server: * Your project should have a separate \{ProjectName}Server.Target.cs file * This file should contain `Type = TargetType.Server;` to enable dedicated server mode * When built in "development server" configuration for Win64, your output contains \{ProjectName}Server.exe * Network-enabled: * There are multiple ways to meet this requirement, but the simple answer is: your client can establish a network connection with a game-server on a separate machine, and communicate meaningfully * Our instructions direct you through Unreal's built-in data replication system, which handles most of this requirement for you * You can establish this connection more directly with a socket, such as through the ISocketSubsystem, which is a much more advanced topic * Multiplayer: * Your game-server can accept multiple incoming client connections, and communicate properly with both * Again, with Unreal's built-in data replication, this requirement is mostly handled for you With a properly configured multiplayer project, you're ready to [install the GSDK](https://docs.xbox.com/services/playfab/multiplayer/servers/server-sdks/unreal-gsdk/third-person-mp-example-gsdk-project-setup.md). This plugin will allow your server to run on PlayFab Multiplayer Services. ## Unreal project build configurations Once the GSDK is installed and configured in your project, you can [build your Unreal project](https://docs.xbox.com/services/playfab/multiplayer/servers/server-sdks/unreal-gsdk/building-the-third-person-mp-example-project.md). There are multiple build configurations you will need to execute the full range of tests in future steps. ## Test local server deployment Once you have any client build, and a "Development Server" build, you can [test the MPS deployment process locally](https://docs.xbox.com/services/playfab/multiplayer/servers/server-sdks/unreal-gsdk/third-person-mp-example-project-local-deployment-and-debugging.md), and verify your server works. ## Deploy to PlayFab You're now ready to create game-servers in the cloud using PlayFab Multiplayer Services. PlayFab MPS supports [Windows servers](https://docs.xbox.com/services/playfab/multiplayer/servers/server-sdks/unreal-gsdk/third-person-mp-example-project-cloud-deployment.md) and [Linux servers](https://docs.xbox.com/services/playfab/multiplayer/servers/server-sdks/unreal-gsdk/setting-up-a-linux-dedicated-server-on-playfab.md). ## Connect to deployed server Finally, you're ready to [connect to your deployed server](https://docs.xbox.com/services/playfab/multiplayer/servers/server-sdks/unreal-gsdk/connect-to-mps-hosted-build.md). ## Acknowledgments Thank you to [Stefan Krismann](https://github.com/stkrwork) for creating and submitting this plugin.
