# Show and hide ads during gameplay

> Hide banner ads during gameplay, show interstitial ads from a script, and show a rewarded ad button only when an ad is available.

After you add ad components to your game, you can control when their ads show. This page covers how to do the following tasks:

* [Hide a banner ad during gameplay](#hide-a-banner-ad-during-gameplay)
* [Show an interstitial ad from a script](#show-an-interstitial-ad-from-a-script)
* [Show a rewarded ad button only when an ad is available](#show-a-rewarded-ad-button-only-when-an-ad-is-available)

## Prerequisites

Before you begin, add the LevelPlay SDK and the ad components you need. For detailed steps, refer to [Get started with LevelPlay components](/grow/levelplay/sdk/unity/get-started-components.md).

## Hide a banner ad during gameplay

The **Banner Ad (LevelPlay)** component loads and displays a banner ad at a fixed position on the screen.

To hide the banner during gameplay, do the following:

1. In your level-start event, call **Banner Ad (LevelPlay)** > **HideAd ()**.
2. In your level-end event, call **ShowAd ()**.

`HideAd()` hides the banner without destroying it.

## Show an interstitial ad from a script

The **Interstitial Ad (LevelPlay)** component loads and shows a full-screen interstitial ad, for example, between levels. You can reference the component from your own scripts. Each component exposes its settings as [public properties](/grow/levelplay/sdk/unity/component-api-reference.md#interstitial-ad-\(levelplay\)-component-class), such as `AndroidAdUnitId`, `LoadOnStart`, and `PlacementName`. It also exposes its events as public `UnityEvent` properties.

The following example shows the interstitial ad when `FinishLevel()` runs, if an ad is ready and the placement isn't capped. Otherwise, it loads the next level. When the ad closes, the `OnAdClosed` listener loads the next level.

```csharp
using Unity.Services.LevelPlay;
using UnityEngine;

public class LevelEnd : MonoBehaviour
{
    [SerializeField] LevelPlayInterstitialAdBehaviour m_Interstitial;

    void OnEnable() => m_Interstitial.OnAdClosed.AddListener(OnInterstitialClosed);
    void OnDisable() => m_Interstitial.OnAdClosed.RemoveListener(OnInterstitialClosed);

    public void FinishLevel()
    {
        if (m_Interstitial.IsAdReady() && !m_Interstitial.IsPlacementCapped())
        {
            m_Interstitial.ShowAd();
        }
        else
        {
            LoadNextLevel();
        }
    }

    void OnInterstitialClosed(LevelPlayAdInfo adInfo) => LoadNextLevel();

    void LoadNextLevel() { /* ... */ }
}
```

To show an interstitial ad from the script, do the following:

1. Create a C# script named `LevelEnd`, paste in the example code, and attach the script to a `GameObject` in the scene.
2. In the **Inspector** window, drag the `GameObject` that has the **Interstitial Ad (LevelPlay)** component into the **Interstitial** field of the **LevelEnd** component.
3. Call `FinishLevel()` when the level ends. Use one of the following options:
   * **From another script**: For example, call `levelEnd.FinishLevel();` in your game-over logic.
   * **From a `UnityEvent` in the Inspector window**: For example, in a UI Button's **On Click ()** list, add an entry, assign the `LevelEnd` `GameObject`, and select **LevelEnd** > **FinishLevel ()**.

When the level ends, the interstitial ad shows if one is ready, and the next level loads after the ad closes. If no ad is ready, the next level loads right away.

To reach features the component doesn't expose, use the [`Ad`](/grow/levelplay/sdk/unity/component-api-reference.md#interstitial-ad-\(levelplay\)-component-class) property to get the underlying `LevelPlayBannerAd`, `LevelPlayInterstitialAd`, or `LevelPlayRewardedAd`.

## Show a rewarded ad button only when an ad is available

To show the button only when an ad is available, enable the button in the **On Ad Loaded** event of the **Rewarded Ad (LevelPlay)** component, and disable it in **On Ad Displayed**.

To set up the button, do the following:

1. In the **Inspector** window, deactivate the button `GameObject` by clearing the checkbox next to its name. The button stays hidden until the first ad loads.
2. In the **Hierarchy** window, select the `GameObject` that has the **Rewarded Ad (LevelPlay)** component.
3. In the **Inspector** window, find **On Ad Loaded** and select **Add** (**+**) to add an entry.
4. Drag your button's `GameObject` from the **Hierarchy** window into the object field of the new entry.
5. In the function dropdown, select **GameObject** > **SetActive (bool)**, then select the checkbox so the event shows the button.
6. Repeat steps 3–5 for **On Ad Displayed**, but leave the checkbox cleared so the event hides the button.

When an ad loads, the button appears. When the ad is displayed, the button hides again until the next ad loads.
