Rewarded Video - C++ Examples

This section contains examples on how to use Rewarded Videos with C++.

Creating a Rewarded Video

To use a Rewarded Video, we first have to create one. You can create a Rewarded Video as any UObjects with the NewObject templated method:

#include "AdMob/RewardedVideo.h"
void UMyClass::CreateRewardedVideo()
{
    UAdMobRewardedVideo* const MyRewardedVideo = NewObject<UAdMobRewardedVideo>();
}

Loading an Ad

Before showing the Rewarded Video, we have to load an ad for it first. To load an ad, call the LoadAd method.

void UMyClass::LoadAdForRewardedVideo()
{
    MyRewardedVideo->LoadAd
    (
        /* Ad unit for the ad. */
        TEXT("ca-app-pub-3940256099942544/3419835294"),
        
        /* Request's keywords. */
        { TEXT("Unreal"), TEXT("Game"), TEXT("Fun") },
        
        /* Callback called when the ad is loaded. */
        FAdMobCallback::CreateUObject(this, &ThisClass::OnRewardedVideoLoaded)
    );
}
// Method called when the ad is loaded.
void UMyClass::OnRewardedVideoLoaded(const EAdMobError Error)
{
    if (Error == EAdMobError::None)
    {
        // The ad is correctly loaded.
    }
    
    else
    {
        // An error occured. Check the exact value of Error to know what went wrong.
    }
}

If you plan to show a Rewarded Video during a precise time as for level transition or on a loading screen, you should load the ad before so the ad is ready when you want to show it.

Showing the Rewarded Video

To show the Rewarded Video, simply call the Show method.

void UMyClass::ShowRewardedVideo()
{
    MyInterstitial->Show();
}

Waiting for Reward

The most important part of showing the rewarded video is to give a reward if the user watched the ad.
To do so, we can bind the OnReward event after we create the Rewarded Video.

void UMyClass::CreateRewardedVideo()
{
    // Creates the Rewarded Video as shown previously.
    UAdMobRewardedVideo* const MyRewardedVideo = NewObject<UAdMobRewardedVideo>();
    
    // Binds our function to the reward event.
    MyRewardedVideo->OnReward.AddDynamic(this, &ThisClass::OnReward);
    
    // Load an ad and show the video...
}
void UMyClass::OnReward(const FString& Type, int32 Amount)
{
    // If this code executes, the user deserves a reward.
}
