Rewarded

Rewarded ads allow players to watch a full video ad in exchange for in-game rewards — such as coins, bonuses, or additional lives.
Unlike interstitials, rewarded ads require explicit user consent to view and always grant a reward upon successful completion.

Rewarded ads must be loaded in advance before being shown.
Once a rewarded has been displayed, it must be loaded again before it can be shown the next time.

---

Load Rewarded

This function loads a rewarded ad using the provided Ad Unit ID.
It must always be called before attempting to show the ad — if no rewarded ad is loaded, calling Show Rewarded will fail immediately.

Parameters

1. Ad Unit ID

Your Rewarded Ad Unit ID from the AdMob console.

---

2. On Loaded

Called when the rewarded ad has been successfully loaded and is ready to show.

---

3. On Load Failed

Called if the ad fails to load due to network issues, invalid configuration, or SDK errors.
This callback returns an EAdErrorCode value and an error message for debugging.

---

Show Rewarded

Displays a previously loaded rewarded ad and grants the user a reward after it finishes successfully.
Before calling this function, make sure that a rewarded ad has already been loaded using Load Rewarded.

Parameters

1. Auto Reload

If enabled, the system will automatically load a new rewarded ad immediately after the current one is shown and completed.
Useful for games with frequent reward opportunities.

---

2. Is Immersive

Enables immersive mode during the ad display — hiding system UI elements (navigation bar, status bar) for a more seamless user experience.

---

3. On Started

Called when the rewarded ad starts displaying.

---

4. On Completed

Called after the ad is fully closed by the user or finishes naturally.

---

5. On Reward Earned

Triggered when the player successfully earns a reward by watching the ad to completion.
Use this callback to grant in-game currency, bonuses, or other benefits.

---

6. On Failure

Called if the ad fails to show (for example, if it wasn’t properly loaded or was invalidated).
This callback returns an EAdErrorCode value and an error message for debugging.

---

7. On Event

Triggered on intermediate ad lifecycle updates — such as when is clicked.
Returns an EFullScreenAdEventType describing the event.

---

Is Rewarded Ready

Checks whether a rewarded ad has been successfully loaded and is ready to be shown.
Use this before calling Show Rewarded to avoid triggering a failed display event.

Return Value

Returns true if a rewarded ad is successfully loaded and ready to display.
Returns false if no ad is currently loaded.

C++ Usage

All rewarded-related Blueprint functions are also available in C++.
You can directly manage rewarded ad loading, showing, and reward handling through the static methods of UAdMobCPPLibrary.

LoadRewarded

#include "AdMobCPPLibrary.h"

void UMyClass::LoadRewarded()
{
    FOnRewardedLoadedNative OnLoaded;
    OnLoaded.BindLambda([]()
    {
        UE_LOG(LogTemp, Log, TEXT("Rewarded ad loaded successfully."));
    });

    FOnRewardedLoadFailedNative OnLoadFailed;
    OnLoadFailed.BindLambda([](EAdErrorCode Error, const FString& Message)
    {
        UE_LOG(LogTemp, Error, TEXT("Failed to load rewarded ad: %s (Code: %d)"), *Message, static_cast<int32>(Error));
    });

    UAdMobCPPLibrary::LoadRewarded(TEXT("ca-app-pub-xxxxxxxxxxxxxxxx/xxxxxxxxxx"), OnLoaded, OnLoadFailed);
}

    });

    FOnRewardedEventNative OnEvent;
    OnEvent.BindLambda([](EFullScreenAdEventType Event)
    {
        UE_LOG(LogTemp, Log, TEXT("Rewarded ad event: %d"), static_cast<int32>(Event));
    });

    UAdMobCPPLibrary::ShowRewarded(true, false, OnStarted, OnCompleted, OnRewardEarned, OnFailure, OnEvent);
}

    UE_LOG(LogTemp, Log, TEXT("Is rewarded ad ready? %s"), bIsReady ? TEXT("Yes") : TEXT("No"));
