Godot AdMob - App Open Ads

Assists with implementing App Open ads using the AppOpenAdLoader and AppOpenAd classes in Godot 4.x.

App Open Ads Workflow

1. Instantiate AppOpenAdLoader: Set up a loader instance.
2. Configure AppOpenAdLoadCallback: Define success (on_ad_loaded) and failure callbacks.
3. Load the Ad: Call app_open_loader.load() passing the Ad Unit ID, AdRequest, and load callback.
4. Handle Loaded Ad: Save the loaded AppOpenAd instance.
5. Configure FullScreenContentCallback: Connect events to destroy/cleanup the ad on dismissal.
6. Show the Ad: Call app_open_ad.show() when the user launches or switches back to your game.
7. Crucial: Destroy the Ad: Call app_open_ad.destroy() inside the dismissed or show failure callbacks to free native memory.

Code Examples

=== "GDScript"

```gdscript
var app_open_ad: AppOpenAd
var app_open_loader := AppOpenAdLoader.new()

func load_app_open_ad() -> void:
	var ad_unit_id := "ca-app-pub-3940256099942544/9257395921" # Test ID
	var callback := AppOpenAdLoadCallback.new()

	callback.on_ad_loaded = func(ad: AppOpenAd) -> void:
		app_open_ad = ad
		print("App Open ad loaded.")
		setup_app_open_callbacks()

	callback.on_ad_failed_to_load = func(error: LoadAdError) -> void:
		print("App Open ad failed to load: ", error.message)

	app_open_loader.load(ad_unit_id, AdRequest.new(), callback)

func setup_app_open_callbacks() -> void:
	if not app_open_ad:
		return
	var callbacks := FullScreenContentCallback.new()
	callbacks.on_ad_dismissed_full_screen_content = func() -> void:
		print("App Open ad dismissed.")
		app_open_ad.destroy()
		app_open_ad = null
	callbacks.on_ad_failed_to_show_full_screen_content = func(error: AdError) -> void:
		print("App Open ad failed to show: ", error.message)
		app_open_ad.destroy()
		app_open_ad = null

	app_open_ad.full_screen_content_callback = callbacks

func show_app_open_ad() -> void:
	if app_open_ad:
		app_open_ad.show()
	else:
		print("App Open ad not loaded yet.")
