Use in Blueprint or C++

Access the API manager from Blueprint or C++ code

// C++ Usage
UIDCGamesAPIManager* API = UIDCGamesAPIManager::GetInstance();
API->Login();

// Blueprint Usage
// Use the "Get IDCGames API Manager" node

Code Examples

Authentication (C++)

// Login using third-party authentication
void AMyGameMode::Login()
{
    UIDCGamesAPIManager* API = UIDCGamesAPIManager::GetInstance();
    API->OnLoginComplete.AddDynamic(this, &AMyGameMode::OnLoginComplete);
    // Supported platforms: sandbox, idc, steam, epic, googleplay, applestore, playstation, nintendo
    API->Login(TEXT("sandbox"), TEXT("unique_user_id"), TEXT("PlayerName"));
}

// Handle login response
void AMyGameMode::OnLoginComplete(bool bSuccess)
{
    if (bSuccess) {
        UE_LOG(LogTemp, Log, TEXT("Login successful!"));
        // Tokens are automatically saved
    }
}

// Refresh token when needed
void AMyGameMode::RefreshToken()
{
    UIDCGamesAPIManager* API = UIDCGamesAPIManager::GetInstance();
    API->RefreshToken();
}

Shop Integration (C++)

// Get shop items
void AMyGameMode::GetShopItems()
{
    UIDCGamesAPIManager* API = UIDCGamesAPIManager::GetInstance();
    API->GetShopItems();
    // Results will be available through events
}

// Buy shop item
void AMyGameMode::BuyItem(int32 ItemId, int32 Quantity)
{
    UIDCGamesAPIManager* API = UIDCGamesAPIManager::GetInstance();
    API->BuyShopItem(ItemId, Quantity);
    // Success/failure will be available through events
}

Stats Submission (C++)

// Submit game statistics
void AMyGameMode::SubmitGameStats()
{
    UIDCGamesAPIManager* API = UIDCGamesAPIManager::GetInstance();
    
    TMap SessionStats;
    SessionStats.Add(TEXT("kills"), 5);
    SessionStats.Add(TEXT("deaths"), 2);
    SessionStats.Add(TEXT("assists"), 3);
    SessionStats.Add(TEXT("wins"), 1);
    SessionStats.Add(TEXT("score"), 1500);
    
    TMap EventProgress;
    EventProgress.Add(TEXT("event_1"), 10);
    EventProgress.Add(TEXT("event_2"), 5);
    
    API->SubmitGameStats(SessionStats, EventProgress);
}
