Developer Settings

User Game Developer Settings

See UGameUserSettings.

Per Editor User Developer Settings

Thanks for Northstar for the example.

UCLASS(Config = EditorPerProjectUserSettings, DefaultConfig) class UMyFrameworkLocalDevSettings : public UDeveloperSettings

This will go into Editor preferences and write to DefaultEditorPerProjectUserSettings.ini in Saved/ which shouldn’t be committed

Miscs

Custom category

To have a custom Config/DefaultMyCustomCategory you can do UCLASS(Config=MyCustomCategory, defaultconfig).

To make the custom category name in the editor/project settings, override CategoryName in the developer settings constructor.

Saving Developer Settings manually

If you are editing the CDO using a mutable ptr, you must use TryUpdateDefaultConfigFile() to write to .ini file. This works for Developer Settings classes with defaultconfig in the UCLASS
