Static variables in BP?

Development Programming & Scripting

I actually find it helpful to share answers, not just tell people they are wrong and to go read more docs. Thus :

Create a C++ blueprint library with a get and set method. In the CPP file add the static variable you wish to edit or retrieve.

Header :

#pragma once

#include "CoreMinimal.h"
#include "Kismet/BlueprintFunctionLibrary.h"
#include "BPFL_WorldUtilities.generated.h"

UCLASS()
class EOS_FPS_API UBPFL_WorldUtilities : public UBlueprintFunctionLibrary
{
	GENERATED_BODY()

	UFUNCTION(BlueprintCallable, Category = "Networking")
		static void SetCurrentLobbyID(FString ID);

	UFUNCTION(BlueprintCallable, Category = "Networking")
		static FString GetCurrentLobbyID();
};

Script :

#include "BPFL_WorldUtilities.h"

static FString LobbyID;
void UBPFL_WorldUtilities::SetCurrentLobbyID(FString ID)
{
	LobbyID = ID;
}
FString UBPFL_WorldUtilities::GetCurrentLobbyID()
{
	return LobbyID;
}

I see a similar answer was given in the comments by @ok_gida
