AppsFlyer Unreal Steam SDK integration

AppsFlyerは、クロスプラットフォームアトリビューションを実行するための強力なツールを提供することで、ゲームマーケティング担当者がより良い意思決定を行えるよう支援します。

Game attribution requires the game to integrate the AppsFlyer SDK that records first opens, consecutive sessions, and in-app events. For example, purchase events.
We recommend you use this sample app as a reference for integrating the AppsFlyer SDK into your Unreal Steam game.

Note: The sample code that follows is currently only supported in a Windows environment.


Prerequisites

  • Unreal Engine 4.2x
  • Steamworks SDKが実装されたUE4(通常、UE4のサードパーティに含まれているため、ダウンロードする必要はありません)
  • Steamクライアントがアクティブなユーザーでインストールされている

AppsflyerSteamModule - Interface

AppsflyerSteamModule.h, included in the appsflyer-unreal-steam-sample-app/AppsflyerSteamIntegrationFiles/AppsflyerSteamModule folder, contains the required code and logic to connect to AppsFlyer servers and report events.

Init

このメソッドは、お客様のAPIキーとアプリIDを受け取り、AppsFlyer Moduleを初期化します。

メソッドのシグネチャ

void Init(const char* devkey, const char* appID, bool collectSteamUid = true)

Arguments:

  • string DEV_KEY: Get from the marketer or AppsFlyer HQ.
  • string STEAM_APP_IDSteamDBから取得できます。
  • bool collectSteamUid: Whether to collect Steam UID or not. True by default.

例:

// for regular init
AppsflyerSteamModule()->Init(<< DEV_KEY >>, << STEAM_APP_ID >>);

// for init without reporting steam_uid
AppsflyerSteamModule()->Init(<< DEV_KEY >>, << STEAM_APP_ID >>, false);

`

Start

このメソッドは、AppsFlyerに first open / session(初回起動 / セッション)のリクエストを送信します。

メソッドのシグネチャ

void Start(bool skipFirst = false)

引数

  • bool skipFirst: Determines whether or not to skip first open events and send session events. The value is false by default. If true , first open events are skipped and session events are sent. See example

例:

// without the flag
AppsflyerSteamModule()->Start();

// with the flag
bool skipFirst = [SOME_CONDITION];
AppsflyerSteamModule()->Start(skipFirst);

Stop

This method stops the SDK from functioning and communicating with AppsFlyer servers. It's used when implementing user opt-in/opt-out.

メソッドのシグネチャ

void Stop()

例:

// Starting the SDK
AppsflyerSteamModule()->Start();
// ...
// Stopping the SDK, preventing further communication with AppsFlyer
AppsflyerSteamModule()->Stop();

LogEvent

このメソッドは、イベント名とJSONオブジェクトを受け取り、アプリ内イベントをAppsFlyerに送信します。

メソッドのシグネチャ

void LogEvent(std::string event_name, std::string event_values, std::string custom_event_values = "")

引数

  • std::string event_name-
  • std::string event_parameters: dictionary object which contains the predefined event parameters.
  • std::string event_custom_parameters (non-mandatory): dictionary object which contains the any custom event parameters. For non-English values, please use UTF-8 encoding.

例:

// Setting the event parameters json string and event name
std::string event_name = "af_purchase";
std::string event_parameters = "{\"af_currency\":\"USD\",\"af_revenue\":24.12}";
// Send the InApp event request
AppsflyerPCModule()->LogEvent(event_name, event_parameters);

// Set non-English values for testing UTF-8 support
std::wstring ws = L"車B1234 こんにちは";
std::wstring ws2 = L"新人邀约购物日";
std::string event_custom_parameters = "{\"goodsName\":\"" + AppsflyerPCModule()->to_utf8(ws) + "\",\"goodsName2\":\"" + AppsflyerPCModule()->to_utf8(ws2) + "\"}";
// Send inapp event with custom params
AppsflyerPCModule()->LogEvent(event_name, event_parameters, event_custom_parameters);

SetCustomerUserId

This method sets a customer ID that enables you to cross-reference your unique ID with the AppsFlyer unique ID and other device IDs. Note: You can only use this method before calling Start().
The customer ID is available in raw data reports and in the postbacks sent via API.

メソッドのシグネチャ

void SetCustomerUserId(std::string cuid)

Arguments:

  • std::string cuid: Custom user id.

例:

AppsflyerSteamModule()->Init(DEV_KEY, STEAM_APP_ID);
AppsflyerSteamModule()->SetCustomerUserId("Test-18-9-23");
AppsflyerSteamModule()->Start();

To_utf8

This method receives a reference of a std::wstring and returns UTF-8 encoded std::string

メソッドのシグネチャ

std::string to_utf8(std::wstring& wide_string);

例:

// Set non-English values for testing UTF-8 support
std::wstring ws = L"車B1234 こんにちは";
std::wstring ws2 = L"新人邀约购物日";
std::string event_custom_parameters = "{\"goodsName\":\"" + AppsflyerPCModule()->to_utf8(ws) + "\",\"goodsName2\":\"" + AppsflyerPCModule()->to_utf8(ws2) + "\"}";

OnCallbackSuccess, OnCallbackFailure

上記のメソッドは、成功/失敗時に必要なアクションのプレースホルダーです。
各機能内 (“FIRST_OPEN_REQUEST”, ”SESSION_REQUEST”, ”INAPP_EVENT_REQUEST”) のコンテキストのスイッチケースで、異なる種類のイベントを処理することが可能です。

メソッドのシグネチャ

void OnCallbackSuccess(long responseCode, uint64 context)
void OnCallbackFailure(long responseCode, uint64 context)

GetAppsFlyerUID

AppsFlyerのユニークデバイスIDを取得します。SDKはアプリのインストール時にAppsFlyerのユニークなデバイスIDを生成します。SDKを起動すると、このIDが最初のアプリインストール時のIDとして記録されます。

メソッドのシグネチャ

std::string GetAppsFlyerUID()

例:

AppsflyerSteamModule()->GetAppsFlyerUID();

IsInstallOlderThanDate

このメソッドは日付文字列を受け取り、ゲームフォルダの修正日が日付文字列より古い場合に true を返します。日付の文字列形式: "2023-January-01 23:12:34"

メソッドのシグネチャ

bool IsInstallOlderThanDate(std::string datestring)

Arguments:

  • std::string datestring: Date string in yyyy-mm-ddThh:mm:ss+hh:mm format.

例:

// the modification date in this example is "2023-January-23 08:30:00"

// will return false
bool dateBefore = AppsflyerSteamModule()->IsInstallOlderThanDate("2023-January-01 23:12:34");

// will return true
bool dateAfter = AppsflyerSteamModule()->IsInstallOlderThanDate("2023-April-10 23:12:34");

// example usage with skipFirst -
// skipping if the install date is NOT older than the given date
bool isInstallOlderThanDate = AppsflyerSteamModule()->IsInstallOlderThanDate("2023-January-10 23:12:34");
AppsflyerSteamModule()->Start(!isInstallOlderThanDate);

SteamゲームにAppsFlyerを実装する

Setup

  1. UE4のサードパーティにSteamが含まれていることを確認します。詳細はこちら
  2. Add the following definitions to Config/DefaultEngine.ini. For reference, see the appsflyer-unreal-steam-sample-app/AppsflyerSteamIntegrationFiles/DefaultEngine.ini file.
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")
DefaultPlatformService=Steam
bEnabled=true
SteamDevAppId=480 //replace "480" with your steam app id.
NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"
  1. Unreal editorでPluginsを開き、Online Subsystem Steamを有効にしてから、エディターを再起動します。
  2. Open the project in your preferred C++ editor and in [YOUR-APP-NAME].Build.cs file, add OpenSSL, OnlineSubsystem, and OnlineSubsystemSteam to your dependencies and HTTP as a private dependency:
PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "HeadMountedDisplay", "OpenSSL", "OnlineSubsystem", "OnlineSubsystemSteam" });
PrivateDependencyModuleNames.Add("HTTP");
  1. Unreal Projectファイルの Sourceディレクトリの下に、AppsflyerSteamModule という名前の新しいディレクトリを作成します。
  2. Copy the following files from appsflyer-unreal-steam-sample-app/AppsflyerSteamIntegrationFiles/AppsflyerSteamModule to the new folder:
  • AppsflyerModule.cpp
  • AppsflyerSteamModule.cpp
  • AppsflyerSteamModule.h
  • DeviceID.h
  • RequestData.h
  1. プロジェクトファイルを生成し、SSLを開きます。詳細はこちら
  2. In the GameMode.h file, add the StartPlay() function:
UCLASS(minimalapi)
class AAppsFlyerSampleGameMode : public AGameModeBase
{
 GENERATED_BODY()

public:
 AAppsFlyerSampleGameMode();
 virtual void StartPlay() override;
};

  1. Open the Source/AppsFlyerSample/AppsFlyerSampleGameMode.cpp file and add the following include to your GameMode.cpp file:
#include "AppsflyerSteamModule/AppsflyerSteamModule.cpp"
  1. Add the following function, making sure to replace DEV_KEY and STEAM_APP_ID in the init function with your app details:
void AAppsFlyerSampleGameMode::StartPlay()
{
 Super::StartPlay();
 if (SteamAPI_Init()) {
    // init the AF module
    AppsflyerSteamModule()->Start();
    // set event name
    std::string event_name = "af_purchase";
    // set json string
    std::string event_parameters = "{\"af_currency\":\"USD\",\"af_revenue\":24.12}";
    // af send inapp event
    AppsflyerSteamModule()->LogEvent(event_name, event_parameters);

    // set non-English values for testing UTF-8 support 
    std::wstring ws = L"車B1234 こんにちは";
    std::wstring ws2 = L"新人邀约购物日";
    std::string event_custom_parameters = "{\"goodsName\":\"" + AppsflyerSteamModule()->to_utf8(ws) + "\",\"goodsName2\":\"" + AppsflyerSteamModule()->to_utf8(ws2) + "\"}";
    // af send inapp event with custom params
    AppsflyerSteamModule()->LogEvent(event_name, event_parameters, event_custom_parameters);
 }
}
  1. AppsFlyer連携をInitialize(初期化)しstart(開始)します。
  2. Report in-app events.
