Custom INI parameters

[nitrogen092]

Hello everyone Please tell me how to add a custom parameter to the “Game User Settings.ini” file? For example:
…
ResolutionSizeX=1920
ResolutionSizeY=1080
bUseVSync=False
…
Music Volume = 0.75 // Custom param

And please tell me, is this done in C++ or BP?

How to store variables to a custom .ini file?

This is an old question but I was having the same problem and happened across the solution, so I figured I’d post it for posterity. Here’s how it works: Your c++ class definition should look like this. UCLASS(config=NewConfigFileName) class YOURGAME_API AExample : public AActor { GENERATED_BODY() UPROPERTY(Config) int32 test_number; UPROPERTY(Config) FString test_string; } Edit: Oh and I almost forgot, you can have other properties in your UPROPERTY declarati…

NewConfigFileName

Can an existing INI file be used as a NewConfigFileName?

[3dRaven]

Well that’s the same macro that is used in the unreal classes
example
UCLASS(config=Engine, defaultconfig, meta=(DisplayName=“Control Rig”))

or

UCLASS(config=Engine, Blueprintable, editinlinenew)

the key seems to have the correct uproperty markup

UPROPERTY(config)

for the game config I believe it’s

UCLASS(config=Game, defaultconfig)

It’s probably a stupid question, but I’m going to ask it anyway… Can I write/read custom parameters via BP? I will create a CPP class using your method that you wrote above, and then via BP I will call GetGameUserSettings->Apply Settings or SaveSettings (it doesn’t matter). Will my custom parameters be saved/applied?

GetGameUserSettings

TBH I’m not sure it will work by default.

You may need to extend UGameUserSettings perhaps overriding ApplySettings, and probably cast to your custom extended GameUserSettings (that’s at least what I’d do)

Thank you very much for telling me in which direction to move!
