Я только что добавил функцию сна и голода к своему виртуальному питомцу, и теперь скрипт не работает, я не уверен, что сделал неправильно, так как все выглядит хорошо.Я покажу вам оригинальный сценарий (который работает) и мой модифицированный.
Я не совсем уверен, что я пропустил, я потратил значительное количество времени на просмотр, чтобы найти свою ошибку, любую помощьбудет принята с благодарностью!
