When the game is ready to be shown to the player, call YandexGames.ready() - for example, after loading the save getData(), you can call this function.
func on_initGame():
# Here you can download the player's data, and then confirm that the game is ready to be shown
YandexGames.ready() # inform Yandex that the player has uploaded
func _ready():
YandexGames.connect("on_initGame", self, "on_initGame") # Connect to the sdk initialization signal

if YandexGames.current_fullscreen_ad_name == "":
