Sign game users up

Enable users to sign up in your UnrealEngine game with the following code. These users will be saved in your GameFuse game and can then login from other devices, since the data is saved online.

Example

void UMyObject::SignUp(const FString& Email, const FString& Password, const FString& PasswordConfirmation, const FString& Username)
{
    // Get the GameFuse User subsystem
    UGameFuseUser* GameFuseUser = GetGameInstance()->GetSubsystem<UGameFuseUser>();

    // Create a typed callback for better type safety
    FGFUserDataCallback CompletionCallback;
    CompletionCallback.BindLambda([this](bool bSuccess, const FGFUserData& UserData)
    {
        if(bSuccess)
        {
            UE_LOG(LogTemp, Display, TEXT("User signed up successfully"));
            UE_LOG(LogTemp, Display, TEXT("Username: %s"), *UserData.Username);
            UE_LOG(LogTemp, Display, TEXT("User ID: %d"), UserData.Id);
        }
        else
        {
            UE_LOG(LogTemp, Error, TEXT("Sign up failed"));
        }
    });

    // Sign up the user
    GameFuseUser->SignUp(Email, Password, PasswordConfirmation, Username, CompletionCallback);
}

To access the game user object from anywhere in the code, you can use the subsystem:

UGameFuseUser* GameFuseUser = GetGameInstance()->GetSubsystem<UGameFuseUser>();
