Unreal Steam
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_ID
SteamDB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 inyyyy-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);

:
UCLASS(minimalapi)
class AAppsFlyerSampleGameMode : public AGameModeBase
{
GENERATED_BODY()
public:
AAppsFlyerSampleGameMode();
virtual void StartPlay() override;
};
- Open the
Source/AppsFlyerSample/AppsFlyerSampleGameMode.cpp
file and add the following include to yourGameMode.cpp
file:
#include "AppsflyerSteamModule/AppsflyerSteamModule.cpp"
- Add the following function, making sure to replace
DEV_KEY
andSTEAM_APP_ID
in theinit
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
