# Interstitial

{% hint style="info" %}
There are some advertisement settings in the `playgama-bridge-config.json` file

[playgama-bridge-config](https://wiki.playgama.com/playgama/sdk/playgama-bridge-config "mention")
{% endhint %}

Interstitial ads typically appear during transitions in the game, such as level loading or after game over.

#### Is Interstitial Supported

Check if the platform supports displaying interstitial ads.

```lua
bridge.advertisement.is_interstitial_supported()
```

#### Minimum Interval Between Displays <a href="#minimum-interval-between-displays" id="minimum-interval-between-displays"></a>

Set the minimum time interval between interstitial ad displays to comply with platform requirements and improve user experience.

```lua
-- Get delay, default value = 60 seconds
bridge.advertisement.minimum_delay_between_interstitial()

-- Set new delay
bridge.advertisement.set_minimum_delay_between_interstitial(30)
```

There should be time intervals between interstitial ad displays. For convenience, this SDK includes a built-in timer mechanism between ad displays. You just need to specify the required interval, and you can call the ad display method as often as you like.

{% hint style="warning" %}
Check the `interstitial_state` at the start of the game, and if the ad is `opened`, perform the necessary actions (mute sounds/pause the game/etc.).
{% endhint %}

Track the state of the interstitial ad to manage ad display and user experience.

```lua
bridge.advertisement.interstitial_state()
```

Possible values: `loading`, `opened`, `closed`, `failed`.

```lua
local bridge = require("bridge.bridge")

function init(self)
	bridge.advertisement.on("interstitial_state_changed", function (_, state)
		print("Interstitial state changed: ", state)
	end)
end
```

{% hint style="info" %}
React to changes in ad state. For example, mute the game sound when `opened` and unmute when `closed` and `failed`.
{% endhint %}

Display an interstitial ad at appropriate moments, such as during level transitions or game over screens.

```lua
local placement = "test_placement" -- optional
bridge.advertisement.show_interstitial(placement)
```

{% hint style="warning" %}
Do not call `show_interstitial()` method at the start of the game. On platforms where this is allowed, the ad will be shown automatically.
