Banner & MREC Ads

Banner and MREC ads are rectangular ad formats that occupy a portion of an app’s layout—often positioned at the top or bottom of the screen or placed inline within scrollable content. They remain visible as users interact with the app, allowing for uninterrupted gameplay or usage, and can be refreshed automatically after a set period.

The following sections show you how to load and then show and hide a banner or MREC ad.

Loading a Banner or MREC

To load a banner or MREC, call CreateBanner() or CreateMRec(), passing it your Ad Unit ID and desired ad view position:

Banners

Blueprint

C++

const FString BannerAdUnitId = TEXT("«ad-unit-ID»");

void InitializeBannerAds()
{
    // Banners are automatically sized to 320×50 on phones and 728×90 on tablets
    // You may call the utility method UAppLovinMAX::IsTablet() to help with view sizing adjustments
    UAppLovinMAX::CreateBanner(BannerAdUnitId, EAdViewPosition::BottomCenter);

    // Set background color for banners to be fully functional
    UAppLovinMAX::SetBannerBackgroundColor(BannerAdUnitId, «banner-background-color»);
}

MRECs

Blueprint

C++

const FString MRecAdUnitId = TEXT("«ad-unit-ID»");

void InitializeMRecAds()
{
    // MRECs are sized to 300x250 on phones and tablets
    // You may use the utility method 'UAppLovinMAX::IsTablet()' to help with view sizing adjustments
    UAppLovinMAX::CreateMRec(MRecAdUnitId, EAdViewPosition::Centered);
}

The complete list of position options are:

• TopLeft
• TopCenter
• TopRight
• Centered
• CenterLeft

• BottomLeft

Set your banner background color to any FColor, for example FColor:Black or FColor:FromHex("#fff200") (yellow).
