Configuration

Editor Configuration

1. Navigate to Edit/Project Settings in the editor, Scroll down on the left panel until the plugins sections of the project settings, Click on LootLockerServerSDK
2. Modify the LootLockerServerKey, Domain Key, Game Version, and AllowTokenRefresh (Set to true if you want the LootLockerServerSDK to attempt to refresh the token if it expires). What values to set, you can find in the LootLocker dashboard. You should already have an account from https://console.lootlocker.com/login

Command Line Configuration

The LootLocker Server SDK supports command line configuration, which is useful for CI/CD pipelines, automated testing, or running different environments without modifying project settings.

How to Use

All config properties marked with UPROPERTY(Config, ...) in ULootLockerServerConfig are automatically exposed and can be overridden at runtime.

Example:

# Override LootLockerServerKey and GameVersion from the command line
MyGame.exe -ini:Game:[/Script/LootLockerServerSDK.LootLockerServerConfig]:LootLockerServerKey=your_key -ini:Game:[/Script/LootLockerServerSDK.LootLockerServerConfig]:GameVersion=1.0.0

More Examples:

# Dev environment
MyGame.exe -ini:Game:[/Script/LootLockerServerSDK.LootLockerServerConfig]:LootLockerServerKey=dev_abc123xyz -ini:Game:[/Script/LootLockerServerSDK.LootLockerServerConfig]:LootLockerDomainKey=mydevdomain -ini:Game:[/Script/LootLockerServerSDK.LootLockerServerConfig]:GameVersion=1.0.0

# Production with verbose logging
MyGame.exe -ini:Game:[/Script/LootLockerServerSDK.LootLockerServerConfig]:LootLockerServerKey=dev_xyz789abc -ini:Game:[/Script/LootLockerServerSDK.LootLockerServerConfig]:LimitLogLevelTo=Verbose -ini:Game:[/Script/LootLockerServerSDK.LootLockerServerConfig]:LogFileName=ProdLog

Notes

• This method works for any property marked with Config in the plugin's config class.
• Overrides are applied at startup and take precedence over values set in the editor or config files.
• For more details, see Unreal's documentation on Command Line Arguments and Config System.
