Loading a Rewarded Ad

The following code shows you how to bind to delegates and load the first rewarded ad:

Blueprint
C++

// UMyWidget.cpp (UMyWidget inherits from UObject to access TimerManager)

#include "UMyWidget.h"
#include "AppLovinMAX.h"

// For retry timer logic
#include "Async/Async.h"
#include "Engine/World.h"
#include "TimerManager.h"

const FString RewardedAdUnitId = TEXT("«ad-unit-ID»");
int RetryAttempt = 0;
FTimerHandle LoadTimerHandle;

void UMyWidget::InitializeRewardedAds()
{
  // Bind member functions to delegates
  UAppLovinMAX::OnRewardedAdLoadedDelegate.AddUObject(this, &UMyWidget::OnRewardedAdLoaded);
  UAppLovinMAX::OnRewardedAdLoadFailedDelegate.AddUObject(this, &UMyWidget::OnRewardedAdLoadFailed);
  UAppLovinMAX::OnRewardedAdDisplayFailedDelegate.AddUObject(this, &MyWidget::OnRewardedAdDisplayFailed);
  UAppLovinMAX::OnRewardedAdHiddenDelegate.AddUObject(this, &UMyWidget::OnRewardedAdHidden);
  UAppLovinMAX::OnRewardedAdReceivedRewardDelegate.AddUObject(this, &UMyWidget::OnRewardedAdReceivedReward);

  // Load first rewarded ad
  LoadRewardedAd();
}

void UMyWidget::LoadRewardedAd()
{
  UAppLovinMAX::LoadRewardedAd(RewardedAdUnitId);
}

void UMyWidget::OnRewardedAdLoaded(const FAdInfo &AdInfo)
{
  // Rewarded ad is ready to be shown. UAppLovinMAX::IsRewardedAdReady(RewardedAdUnitId) will now return 'true'

  // Reset retry attempt
  RetryAttempt = 0;
}

void UMyWidget::OnRewardedAdLoadFailed(const FAdInfo &AdInfo, const FAdError &AdError)
{
  // Rewarded ad failed to load
  // AppLovin recommends that you retry with exponentially higher delays, up to a maximum delay (in this case 64 seconds)

  RetryAttempt++;

  AsyncTask(ENamedThreads::GameThread, [this]() {
    float RetryDelay = FMath::Pow(2.0f, FMath::Min(6, RetryAttempt));
    GetWorld()->GetTimerManager().SetTimer(LoadTimerHandle, this, &UMyWidget::LoadRewardedAd, RetryDelay, false);
  });
}

void UMyWidget::OnRewardedAdDisplayFailed(const FAdInfo &AdInfo, const FAdError &AdError)
{
  // Rewarded ad failed to display. AppLovin recommends that you load the next ad.
  LoadRewardedAd();
}

void UMyWidget::OnRewardedAdHidden(const FAdInfo &AdInfo)
{
  // Rewarded ad is hidden. Pre-load the next ad.
  LoadRewardedAd();
}

void UMyWidget::OnRewardedAdReceivedReward(const FAdInfo &AdInfo, const FAdReward &Reward)
{
  // Rewarded ad was displayed and user should receive the reward
}

Showing a Rewarded Ad

To show a rewarded ad, call ShowRewardedAd():

Blueprint
C++

Ad Unit Identifier. Is Rewarded Ad Ready: Ad Unit Identifier, Return Value. Branch: Condition (True). Show Rewarded Ad: Ad Unit Identifier, Placement.

if (UAppLovinMAX::IsRewardedAdReady(RewardedAdUnitId))
{
  UAppLovinMAX::ShowRewardedAd(RewardedAdUnitId);
}
