Getting an array entry from project settings

[Marmot]

I’m trying to get a value from a struct in an array that is part of the project settings.

I know you can get a string like this:

FString UBpFuncs::GetGameName()
{
    FString projName;
    GConfig->GetString(TEXT("/Script/EngineSettings.GeneralProjectSettings"), TEXT("ProjectName"), projName, GGameIni);

    return projName;
}

But how would you get a value out of an array?

This is the .h file where I make the settings:

UCLASS(config=Game, DefaultConfig, DisplayName="Game Settings")
class SIBERIA_API USiberiaDeveloperSettings : public UDeveloperSettings
{
	GENERATED_BODY()


public:

	USiberiaDeveloperSettings(const FObjectInitializer &ObjectInitializer);

	UPROPERTY(config, BlueprintReadOnly, EditAnywhere, Category="AI")
	TArray<FDifficulty> Difficulties;

	static const USiberiaDeveloperSettings* Get();
};

And this is the FDifficulty struct:

USTRUCT(BlueprintType)
struct FDifficulty
{
	GENERATED_USTRUCT_BODY()

public:

	UPROPERTY(BlueprintReadWrite, EditAnywhere)
	FName DifficultyName;

	UPROPERTY(BlueprintReadWrite, EditAnywhere)
	float DamageMult = 1.f;

	FDifficulty() {};

	FDifficulty(FName DifName, float DmgMult):
	DifficultyName(std::move(DifName)),
	DamageMult(std::move(DmgMult))
	{};
};

I want to get either the FDifficulty of a specific index, or one of the values within that FDifficulty (like the DifficultyName)

And this is from the “DefaultGame.ini” file in the “Config” folder

[/Script/Siberia.SiberiaDeveloperSettings]
+Difficulties=(DifficultyName="Easy",DamageMult=0.500000)
+Difficulties=(DifficultyName="Normal",DamageMult=1.000000)
+Difficulties=(DifficultyName="Hard",DamageMult=1.500000)

Let me know if you need any other info.

Thanks.

As mentioned here, since your Difficulties array is declared with Config, Unreal will load the CDO of this class using the corresponding ini values. To get that simply call GetMutableDefault<>() on your class like so and you will have access to those loaded config values:

USiberiaDeveloperSettings* Settings = GetMutableDefault<USiberiaDeveloperSettings>();

Hope that helps.

That seems to work. But if you know how to do it with something like GConfig->GetString() that would be nice too.

But it works at least. Thank you!
