Godot AdMob - Banner Ads

Assists with implementing, displaying, and destroying banner ads using the AdView and AdSize classes in Godot 4.x.

Banner Ads Workflow

1. Define and Instantiate AdView: Create an AdView with your Ad Unit ID, selected AdSize, and screen AdPosition.
2. Configure AdListener: Set up an AdListener to respond to events such as on_ad_loaded, on_ad_failed_to_load, etc.
3. Load the Ad: Call ad_view.load_ad(AdRequest.new()).
4. Crucial: Destroy the Ad: Call ad_view.destroy() inside _exit_tree() or when changing scenes to free memory.

Code Examples

=== "GDScript"

```gdscript
var ad_view: AdView

func load_banner_ad() -> void:
	var ad_unit_id := "ca-app-pub-3940256099942544/6300978111" # Test ID
	var ad_size := AdSize.get_current_orientation_anchored_adaptive_banner_ad_size(AdSize.FULL_WIDTH)
	var ad_position := AdPosition.BOTTOM

	ad_view = AdView.new(ad_unit_id, ad_size, ad_position)

	var listener := AdListener.new()
	listener.on_ad_loaded = func() -> void:
		print("Banner loaded successfully.")
	listener.on_ad_failed_to_load = func(error: LoadAdError) -> void:
		print("Banner failed to load: ", error.message)

	ad_view.ad_listener = listener

	# To request a collapsible banner:
	# var request := AdRequest.new()
	# request.extras = {"collapsible": "bottom"}
	# ad_view.load_ad(request)

	ad_view.load_ad(AdRequest.new())

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