Unreal SDK

Install the SDK

Download the latest version of AmplitudeUnreal.zip from the GitHub releases page. Unzip the file into a folder inside your Unreal project's Plugins directory.

mkdir -p Plugins/AmplitudeUnreal
unzip AmplitudeUnreal.zip -d Plugins/AmplitudeUnreal

Enable the SDK plugin in the editor

Open your project in the UE4 editor. Go to Settings > Plugins > Project > Analytics and enable AmplitudeUnreal.

Enable Amplitude as the analytics provider

Go to Settings > Project Settings > Analytics > Amplitude and fill in the fields with your API key.

Include the required analytics modules

In any file that involves instrumentation, include the Unreal Engine analytics headers.

#include "Runtime/Analytics/Analytics/Public/Analytics.h"
#include "Runtime/Analytics/Analytics/Public/Interfaces/IAnalyticsProvider.h"

Track events and user properties

The Amplitude Unreal API follows the analytics provider interface that Unreal Engine defines.

Log basic events

Events represent how users interact with your app. For example, you can track a Game Started event.

FAnalytics::Get().GetDefaultConfiguredProvider()->StartSession();
FAnalytics::Get().GetDefaultConfiguredProvider()->RecordEvent(TEXT("Game started"));
FAnalytics::Get().GetDefaultConfiguredProvider()->EndSession();

Log events with properties

Events can contain properties. Properties give context about the event.

TArray<FAnalyticsEventAttribute> AppendedAttributes;
AppendedAttributes.Emplace(TEXT("Test Event Prop key1"), TEXT("Test Event value1"));
AppendedAttributes.Emplace(TEXT("Test Event Prop key2"), TEXT("Test Event value2"));
FAnalytics::Get().GetDefaultConfiguredProvider()->RecordEvent(TEXT("Game Started"), AppendedAttributes);

Set user properties

User properties describe your users at the time they take an action in your app.

The generic Unreal Engine IAnalyticsProvider supports a limited number of user properties.

FAnalytics::Get().GetDefaultConfiguredProvider()->SetLocation(TEXT("Test location"));
FAnalytics::Get().GetDefaultConfiguredProvider()->SetGender(TEXT("Test gender"));
FAnalytics::Get().GetDefaultConfiguredProvider()->SetAge(TEXT(27));

Set custom user IDs

If your app has its own login system, use SetUserId to set a custom user ID.

FAnalytics::Get().GetDefaultConfiguredProvider()->SetUserID(TEXT("test123@test.com"));
