⚙️Preparing The Project For Use With This Plugin

If you also use the Steam Achievements or the Steam DLC plugin you only need to do this once

1. Enable the "OnlineSubsystem", the "OnlineSubsystemUtils" & the "OnlineSubsystemSteam" plugins which are pre-installed in the engine.

2. Edit the "DefaultEngine.ini" file of your project (X:\…\YourProjectName\Config\DefaultEngine.ini) and insert the following at the end:

[/Script/Engine.GameEngine]
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

[OnlineSubsystem]
DefaultPlatformService=Steam

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480

[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"

Instead of “480” you should use your own Steam Dev App ID (Can be found next to your game's name in your Steamworks dashboard). For testing purposes or for developing, you can use “480” though. Just don’t forget that other leaderboards already exist which were created by other developers 😉

1. Restart the engine

2. Start Steam/Let it run in the background

3. Be logged into a Steam account that owns the game (Everyone automatically owns the game with the Dev App ID of 480, it is just hidden)

4. Use Play in Standalone, Launch, or Package your game. (Doesn’t work in PIE aka. Play in Editor)

This plugin is now ready to be used ✅

Common mistake when using asynchronous nodes:

Make sure to always use the "On Success" and the "On Fail" pin.

The exec pin above these two runs instantly so it runs before the asynchronous node has any results.
