Jestem nowy w programowaniu, więc bądź miły. Tworzę grę w Swift 3, podobną do Flappy Bird, i mam problem z węzłem punktacji. Utworzyłem węzeł etykiety dla partytury, ale kiedy gracz kontaktuje się z węzłem scoreDetect, żaden wynik nie jest dodawany. Nie mogę stwierdzić, czy zakodowałem część, która dodaje punkt nieprawidłowo, czy też mój kod fizyki jest nieprawidłowy. Każda pomoc jest mile widziana. Dzięki.

Odpowiedzi:
3 dla odpowiedzi № 1Prawidłowo aktualizujesz scoreValue własność. Jednak musisz również zaktualizować to, co jest wyświetlane w pliku scoreLabel zgodnie z nową wartością scoreValue.
Więc wymień to
var scoreValue = Int()
z tym
var scoreValue = Int() {
didSet {
scoreLabel.text = self.scoreValue.description
}
}
Teraz za każdym razem scoreValue zmiany, scoreLabel jest aktualizowana automatycznie.
