Quickstart: Win32

Get started with the PlayFab Services SDK for Win32. Follow these steps to include the libraries in your project and try out the sample code for basic PlayFab functionality. This quickstart helps you make your first PlayFab API call using the Win32 SDK. Before continuing, make sure you’ve completed the steps in Quickstart: Game Manager, which ensure you have a PlayFab account and are familiar with the PlayFab Game Manager.

Requirements

A PlayFab developer account.
Visual Studio 2022 installed.

Project setup

Download the PlayFab SDK to your project from the PlayFab SDK Release Page. Import PlayFabServicesSDK.Win32.props to your project. You can do this manually in the project file or by opening the Property Manager window in Visual Studio, right clicking on the project, and choosing Add Existing Property Sheet.

Troubleshooting

If you have issues linking the SDK in your project, you may need to install 17.5 build tools and libs via the Visual Studio Installer. Click Modify for VS2022, and install these two components.

Init and Logging in

Headers

Include PFServices.h to get access to all included PlayFab functionality:

#include <playfab/services/PFServices.h>

Initialization

PlayFab initialization requires two function calls: PFServicesInitialize and PFServiceConfigCreateHandle. The result of this initialization is a PFServiceConfigHandle. You provide this handle to a subsequent login call, directing the call to the correct title in the PlayFab backend.

    HRESULT hr = PFServicesInitialize(nullptr); // Add your own error handling when FAILED(hr) == true

    PFServiceConfigHandle serviceConfigHandle{ nullptr };

    hr = PFServiceConfigCreateHandle(
            "https://ABCDEF.playfabapi.com",    // PlayFab API endpoint - obtained in the Game Manager
            "ABCDEF",                           // PlayFab Title id - obtained in the Game Manager
            &serviceConfigHandle);

Logging in

Once you have a PFServiceConfigHandle, you can use it to make a player login call. In the SDK, use a PFAuthenticationReLoginWith*Async method like PFAuthenticationLoginWithSteamAsync. This function allows you to log in a player to PlayFab using a SteamTicket. After making a login call, you can check the status of the call with XAsyncGetStatus. The status starts as E_PENDING and changes to S_OK after the call completes successfully. If the call fails for some reason, the status reflects that failure. Error handling on all PlayFab Services calls works this way. Along with an S_OK result, you get back a PFEntityHandle. You use this handle to make subsequent PlayFab calls as the logged in player. It includes any material required to authenticate with the PlayFab service as that player.

    PFAuthenticationLoginWithSteamRequest request{};
    request.createAccount = true;
    request.steamTicket = steamTicket; // A ticket obtained from Steam

    XAsyncBlock async{};
    HRESULT hr = PFAuthenticationLoginWithSteamAsync(serviceConfigHandle, &request, &async); // Add your own error handling when FAILED(hr) == true
    hr = XAsyncGetStatus(&async, true); // This is doing a blocking wait for completion, but you can use the XAsyncBlock to set a callback instead for async style usage

    std::vector<char> loginResultBuffer;
    PFAuthenticationLoginResult const* loginResult;
    size_t bufferSize;
    hr = PFAuthenticationLoginWithSteamGetResultSize(&async, &bufferSize);
    loginResultBuffer.resize(bufferSize);

    PFEntityHandle entityHandle{ nullptr };
    hr = PFAuthenticationLoginWithSteamGetResult(&async, &entityHandle, loginResultBuffer.size(), loginResultBuffer.data(), &loginResult, nullptr);

Service Calls

After logging the player in, you can now make calls to the PlayFab backend. Here’s an example of a call to get files stored in PlayFab for the current player.

Getting the EntityKey

One thing that can be useful for some calls to PlayFab is knowing the PFEntityKey of the player. Once you have a PFEntityToken, you can retrieve a PFEntityKey with PFEntityGetEntityKey.

    PFEntityKey const* pEntityKey{};
    std::vector<char> entityKeyBuffer;
    size_t size{};
    HRESULT hr = PFEntityGetEntityKeySize(entityHandle, &size); // Add your own error handling when FAILED(hr) == true

    entityKeyBuffer.resize(size);
    hr = PFEntityGetEntityKey(entityHandle, entityKeyBuffer.size(), entityKeyBuffer.data(), &pEntityKey, nullptr);

Calling GetFiles

All PlayFab calls follow a similar pattern of preparing the request object, making the call (using the PFEntityHandle from login), creating an object to receive the response, and then calling a GetResult function to fill the newly created container.

    XAsyncBlock async{};
    PFDataGetFilesRequest requestFiles{};
    requestFiles.entity = pEntityKey;

    HRESULT hr = PFDataGetFilesAsync(entityHandle, &requestFiles, &async); // Add your own error handling when FAILED(hr) == true
    hr = XAsyncGetStatus(&async, true); // This is doing a blocking wait for completion, but you can use the XAsyncBlock to set a callback instead for async style usage

    size_t resultSize;
    hr = PFDataGetFilesGetResultSize(&async, &resultSize);

    std::vector<char> getFilesResultBuffer(resultSize);
    PFDataGetFilesResponse* getFilesResponseResult{ nullptr };
    hr = PFDataGetFilesGetResult(&async, getFilesResultBuffer.size(), getFilesResultBuffer.data(), &getFilesResponseResult, nullptr);

Clean up

When your game is ready to shut down or you need to clean up PlayFab for some other reason, ensure you close all open handles and call PFServicesUninitializeAsync.

    PFEntityCloseHandle(entityHandle);
    entityHandle = nullptr;

    PFServiceConfigCloseHandle(serviceConfigHandle);
    serviceConfigHandle = nullptr;

    XAsyncBlock async{};
    HRESULT hr = PFServicesUninitializeAsync(&async); // Add your own error handling when FAILED(hr) == true
    hr = XAsyncGetStatus(&async, true); // This is doing a blocking wait for completion, but you can use the XAsyncBlock to set a callback instead for async style usage

Async API pattern

The PlayFab Services SDK follows the Asynchronous Programming Model implemented in the GDK. This programming model involves the use of Tasks and Task Queues provided by the XAsync library. This model is consistent with other GDK functions and extensions (such as the XBOX Services API). While it does introduce some complexity, it also brings a high degree of control over asynchronous operations. This example shows how to make an asynchronous call to PFDataGetFilesAsync.

    auto async = std::make_unique<XAsyncBlock>();
    async->callback = [](XAsyncBlock* async)
    {
        std::unique_ptr<XAsyncBlock> asyncBlockPtr{ async }; // take ownership of XAsyncBlock

        size_t resultSize;
        HRESULT hr = PFDataGetFilesGetResultSize(async, &resultSize);
        if (SUCCEEDED(hr))
        {
            std::vector<char> getFilesResultBuffer(resultSize);
            PFDataGetFilesResponse* getFilesResponseResult{ nullptr };
            PFDataGetFilesGetResult(async, getFilesResultBuffer.size(), getFilesResultBuffer.data(), &getFilesResponseResult, nullptr);
        }
    };

    PFDataGetFilesRequest requestFiles{};
    requestFiles.entity = m_pEntityKey;
    HRESULT hr = PFDataGetFilesAsync(m_entityHandle, &requestFiles, async.get());
    if (SUCCEEDED(hr))
    {
        async.release(); // at this point, the callback will be called so release the unique ptr
    }

Error handling

Completed XAsync operations return HTTP status codes. An error status code manifests as a failure HRESULT such as HTTP_E_STATUS_NOT_FOUND when calling XAsyncGetStatus() or one of the PF*Get() APIs. To see detailed error messages returned by the service see the next section on debugging. These detailed error messages can be useful during development to better understand how the PlayFab service reacts to requests from the client.

Debugging

The easiest way to see the results and debug any calls in the PlayFab Services SDK is to enable Debug Tracing. Enabling debug tracing allows you to both see the results in the debugger output window and hook the results into your game’s own logs.
