Monetize your Unreal Engine mobile games with Google AdMob — Rewarded Video, Banner, Interstitial, Native, and App Open ads, fully driven from Blueprint or C++..

Alpha Ads - Google AdMob Integration is a complete, drop-in monetization plugin that bridges the Google Mobile Ads (AdMob) SDK into Unreal Engine for Android and iOS. Load, show, and react to ads without writing a single line of native Java or Objective-C — every call and every callback is exposed as a clean Blueprint node and a C++ API.

Configure everything once in Project Settings, then call ads from anywhere through a Game Instance Subsystem, a spawnable Actor Component, or static Blueprint function nodes. Bind to lifecycle events to drive your UI, grant rewards, and track impressions..

--------------------------------------------------

AD FORMATS (5)

--------------------------------------------------

• Rewarded Video — Load, Show, and check Is Ready; fires a reward callback with the reward amount.

• Banner — Load, Show, Hide, Destroy; choose size and on-screen position at runtime.

• Interstitial — Load, Show, and check Is Ready; full-screen between-level ads.

• Native — Load native placements that blend with your UI.

• App Open — Load, Show, and check Is Ready; show an ad on app launch / resume.

--------------------------------------------------

HOW YOU CALL IT (4 access paths)

--------------------------------------------------

• AdMob Subsystem (Game Instance Subsystem) — global, world-context access to every ad call and every event delegate. "Get AdMob Subsystem" from any Blueprint and go.

• AdMob Component (Actor Component, BlueprintSpawnableComponent) — drop it on any actor to bind ad events locally.

• AdMob Functions — static Blueprint-callable nodes for every load/show/state call.

• AdMob Blueprint Library — static utility helpers (version, support checks, runtime privacy toggles).

TECHNICAL DETAILS

--------------------------------------------------

• Engine: Unreal Engine 5.7

• Platforms (ad delivery): Android, iOS

• Development platforms: Windows, Mac

• Code Modules: 1 — AdMob (Runtime)

• Number of Blueprints: 0 (pure C++; contains no content assets)

• Number of C++ Classes: 9 (AdMobBPLibrary, AdMobComponent, AdMobFunctions, AdMobSettings, AdMobSubsystem, AdMobTestGameMode, AdMobTestWidget, plus the IAdMob interface and FAdMob module)

• Network Replicated: No

• Cross-platform-safe: compiles into Windows, Mac, and Linux editor and packaged builds as a no-op, so desktop pipelines keep building.

• Third-party SDK: Google Mobile Ads SDK — Android v21.5.0, iOS v11.13.0 (Google LLC). Fetched via Gradle/Maven (Android) and CocoaPods (iOS) at build time; no Google source code is distributed with this plugin.

--------------------------------------------------

SETUP

--------------------------------------------------

1. Enable the plugin and restart the editor.

2. Open Project Settings > Plugins > AdMob and enter your App Id and Ad Unit IDs; set Test Mode while developing.

3. Set your GDPR / COPPA flags (or toggle them at runtime via the Blueprint Library).

4. From the AdMob Subsystem (or AdMob Component / Functions), call Load then Show for the format you want, and bind to its events.

5. Package for Android or iOS.

NOTES

--------------------------------------------------

• An AdMob account and valid Ad Unit IDs are required. Always test with Google's official test ad unit IDs (or enable Test Mode) before going live.

• Ads serve only on Android and iOS devices; desktop builds compile the plugin as a no-op.

• Built-in GDPR consent and COPPA compliance flags, configurable in settings and at runtime.
