Rewarded ads not working or delayed about godot-admob-android

[gumaciel]

Hi, your code is not wrong, but you are noticing this because you are not waiting for the reward_ad to be loaded to click on the button, I did some modifications for you:

extends Button

var rewarded_ad : RewardedAd
var rewarded_ad_load_callback := RewardedAdLoadCallback.new()
var on_user_earned_reward_listener := OnUserEarnedRewardListener.new()
var _full_screen_content_callback := FullScreenContentCallback.new()

@export var reward_type : String
@export_category("skin")
@export var skin_name : String

func _ready():
	rewarded_ad_load_callback.on_ad_failed_to_load = on_rewarded_ad_failed_to_load
	rewarded_ad_load_callback.on_ad_loaded = on_rewarded_ad_loaded
	on_user_earned_reward_listener.on_user_earned_reward = on_user_earned_reward
    _full_screen_content_callback.on_ad_dismissed_full_screen_content = func() -> void:
        your_button.disabled = true
		if _rewarded_ad:
			_rewarded_ad.destroy()
			_rewarded_ad = null
		load_ad()
	your_button.disabled = true
	load_ad()

func load_ad() -> void:
	var unit_id : String
	if OS.get_name() == "Android":
		unit_id = "ca-app-pub-3940256099942544/5224354917"
	elif OS.get_name() == "iOS":
		unit_id = "ca-app-pub-3940256099942544/1712485313"
 
	RewardedAdLoader.new().load(unit_id, AdRequest.new(), rewarded_ad_load_callback)

func on_rewarded_ad_failed_to_load(adError : LoadAdError) -> void:
	print(adError.message)
	
func on_rewarded_ad_loaded(rewarded_ad : RewardedAd) -> void:
	print("rewarded ad loaded " + str(rewarded_ad._uid))
	self.rewarded_ad = rewarded_ad
	self.rewarded_ad.full_screen_content_callback = _full_screen_content_callback
	your_button.disabled = false

func on_user_earned_reward(rewarded_item : RewardedItem): # not using rewarded_item
	print("on_user_earned_reward, rewarded_item: rewarded", rewarded_item.amount, rewarded_item.type)

func _on_pressed():
	if rewarded_ad:
		rewarded_ad.show(on_user_earned_reward_listener)
