How get Project Settings values?

Development Programming & Scripting

While I can’t teach you how to code in CPP in a UE4 answers comment, I can give some snippets. There are tons of programming guides on the UE4 help site and forums to get started with UE4 programming.

I assume you want this generally available in your project, so you need to add this to a Blueprint function library. In the header file of the class you made, first extend your class by UBlueprintFunctionLibrary (replacing UMyBlueprintLibrary with your class name):

UMyBlueprintLibrary : public UBlueprintFunctionLibrary

You might need to add “#include “Kismet/BlueprintFunctionLibrary.h”” before the other includes if it moans about UBlueprintFunctionLibrary.

In the “public:” section, create a new UFUNCTION like so:

UFUNCTION(BlueprintCallable, Category="Game Config")
static FString GetAppVersion();

Then in the CPP file, create the actual function:

FString UMyBlueprintLibrary::GetAppVersion() {
	FString AppVersion;
	GConfig->GetString(
		TEXT("/Script/EngineSettings.GeneralProjectSettings"),
		TEXT("ProjectVersion"),
		AppVersion,
		GGameIni
	);
	return AppVersion;
}
