How get Project Settings values?

martoof · February 23, 2015, 4:30am

Hi,

How can i get/set values in Project Settings/Project/Description ? like Project Version, Company Name… ?

I think it’s possible to read/write inside DefaultGame.ini with blueprint in realtime ?

Thanks

Can’t do this in Blueprint (can’t find a way at least).
But it’s not hard in CPP to make a simple Blueprint function.

CPP:

FString AppVersion;
GConfig->GetString(
  TEXT("/Script/EngineSettings.GeneralProjectSettings"),
  TEXT("ProjectVersion"),
  AppVersion,
  GGameIni
);

I also tried using the EngineSettings object, but I couldn’t get it compiling. So, reading ini file directly will have to do!

you for this, and I know this is not my topic but can you explain to me how to create this Blueprint node step by step? What I’ve done so far is: File-> Add code to project… and created an empty class. Is that alright or should I choose a different one. And now what? I’m sorry to ask this but I can’t find any good tutorials on this out there.

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;
}

I’ve created a video tutorial for those who need some help in the future:

Thanks for the code snippet! To compile on 4.20 I had to add this include : #include “Misc/ConfigCacheIni.h”
Cheers

Edit the project version setting (Edit > Project settings… > Project > Description > About > Project Version)
Use the [VictoryPlugin][1]'s Victory Get Custom Config Var String node to access the value:

I actually just released a plugin that implements this feature! It’s called Fortuna Extended Function Library and contains functions for retrieving project settings, legal info, company info, and a bunch more
