Godot AdMob - Native Overlay Ads

Assists with implementing Native Overlay ads (rendering Google AdMob assets directly inside custom layout templates using Control nodes) in Godot 4.x.

Native Overlay Workflow

1. Define and Instantiate NativeAdLayout: Select a layout template (small or medium) and configure the styles.
2. Instantiate NativeAdLoader: Create the loader using your Ad Unit ID and layout.
3. Configure NativeAdLoadCallback: Define success (on_ad_loaded) and failure callbacks.
4. Load the Ad: Call native_ad_loader.load() passing an AdRequest and load callback.
5. Configure FullScreenContentCallback: Connect events to handle ad dismissal or click.
6. Crucial: Destroy the Ad: Call native_ad.destroy() inside _exit_tree() or when changing scenes to free native memory.

Code Examples

=== "GDScript"

```gdscript
var native_ad: NativeAd
var native_loader: NativeAdLoader

func load_native_ad() -> void:
	var ad_unit_id := "ca-app-pub-3940256099942544/2247696110" # Test ID

	# Configure visual template layout
	var layout := NativeAdLayout.new()
	layout.template_type = NativeAdLayout.TemplateType.SMALL

	# Optional styling (custom colors/backgrounds)
	# layout.style = ...

	native_loader = NativeAdLoader.new(ad_unit_id, layout)

	var callback := NativeAdLoadCallback.new()
	callback.on_ad_loaded = func(ad: NativeAd) -> void:
		native_ad = ad
		print("Native ad loaded successfully.")
		setup_native_callbacks()

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

	native_loader.load(AdRequest.new(), callback)

func setup_native_callbacks() -> void:
	if not native_ad:
		return
	var callbacks := FullScreenContentCallback.new()
	callbacks.on_ad_dismissed_full_screen_content = func() -> void:
		print("Native ad dismissed.")
		native_ad.destroy()
		native_ad = null

	native_ad.full_screen_content_callback = callbacks

func _exit_tree() -> void:
	if native_ad:
		native_ad.destroy()
		native_ad = null
