Fehler in der Pygame-Segmentierung: Problem mit Klassierung und Rekursion?

An diesem Projekt arbeiten: https://github.com/Roland00111/Trumpocalypse/tree/Recursion/Trumpoclypse%20UI. Das Programm wird mit python Trumpocalypse.py gestartet.Fehler in der Pygame-Segmentierung: Problem mit Klassierung und Rekursion?

Der Fehler ist:

Fatal Python error: (pygame parachute) Segmentation Fault 
Aborted (core dumped)

auf einer anderen Maschine eine Ausgabe über max Rekursionstiefe besteht. Es gibt einige Orte, wo Rekursion auftreten könnte.

Es gibt ein Pygame während der Ereignisschleife, die in einer Klasse namens Menu aufgerufen wird. Jedes Mal, wenn die Eingabetaste gedrückt wird, stoppt die Ereignisschleife. Dann wird eine neue Menüklasse aufgerufen. Und dann startet diese neue Menü-Klasse eine neue While-Event-Schleife. Die Menü-Klassen sind alle Unterklassen einer Haupt-Menü-Klasse.

Da jede neue Menu-Klasse im vorherigen Menü initiiert wird, tritt dort möglicherweise eine Rekursion auf.

Zum Beispiel Menü: OpeningMenu() führt die erste while-Ereignisschleife aus. Dann, wenn das erste Element ausgewählt ist Menü: CreateCharacter() führt eine neue while-Ereignisschleife aus. Dann, wenn das zweite Element ausgewählt ist Menü: CreateCharacterAutomatic() führt eine neue While-Ereignisschleife aus. Dann, wenn das erste Element ausgewählt ist Menü: StoryScreen() führt eine neue While-Ereignisschleife aus. Und jetzt wählen Sie den ersten Artikel etwa 60 mal. Dies wechselt zwischen neuen Instanzen von Menu: StoryScreen() und Menu: DayScreen(). Nach ungefähr dem 60. Mal wird der Segfault auftreten.

Interessant ist, dass der Segfault nicht auftritt, wenn vor dem Menü: DayScreen() Code irgendwo vorgelesen wird. Wenn Sie also von Menu: OpeningMenu() zu Menu: HighScores() und wieder endlos zurückkehren, wird der Segfault nicht ausgelöst. Interessant ist hier jedoch Folgendes: Wenn Sie zur ersten Instanz von Menu: DayScreen() gehen, werden sofort die Standardwerte angezeigt. Das heißt, welcher Zähler, der 60 von etwas benötigt, ist bereits beim ersten Öffnen von Menu: DayScreen() gesetzt und der Segfault tritt tatsächlich auf.

Running previous_menu.__del__() scheint das Problem nicht zu lösen. Obwohl dies tatsächlich das vorherige Menü verlässt, gibt es immer noch einen Segmentierungsfehler, der während Menu: DayScreen() auftritt.

aktualisieren

Jetzt sehen:

RuntimeError: maximum recursion depth exceeded while getting the str of an object

Dies ist nach für jede Vererbungs Klasse Menü zwei Anrufe Umsetzung:

Menu.__init__(self) 
previous_menu.__del__()

Wo previous_menu das letzte Menü-Instanz, die die gestartet vorliegende Instanz. Ist das ein Problem mit Pygame oder ein Problem mit dem Aufruf der Klassen in Python durch den Code?

Um den Fehler zu reproduzieren: Wählen Sie "Start", wählen Sie "Auto", wählen Sie "Beginnen Sie Ihr Abenteuer", wählen Sie "Start Day", wählen Sie "Next Day". Machen Sie nun "Start Day" und "Next Day" etwa 120 Mal (jeweils 60 Mal). Ungefähr zu diesem Zeitpunkt wird der Rekursionsfehler ausgelöst.Hier

Lösung

Die Klasse eine andere Klasse rief und damit Rekursion. (Vorbei an der übergeordneten Instanz, um das Kind für das Kind die Eltern anzuweisen, sich am Ende wurde entweder nicht funktioniert oder nicht korrekt implementiert.) Zum Beispiel:

class Menu1(): 
    def __init__(self): 
     Menu2(self) 
class Menu2(): 
    def __init__(self, previous): 
     previous.__del__() # Not working.

Die Lösung für jetzt ist eine Elternklasse direkt zu haben, die Klassen zum Anrufen. Zum Beispiel:

Dies funktioniert und tritt nicht in das Problem mit Rekursion.

Sie müssen Ihr Menüsystem überdenken. Die keypressFunction und die __init__ Methoden der Menu Unterklassen verursachen die Rekursion.

In jeder __init__ Methode des Menü Subklassen rufen Sie self.keypressFunction, die dann die nächste Menüunterklasse in Zeile instanziiert 275 self.keypressArray[chosen_position](self) die self.keypressFunction in seinem __init__ wieder und so weiter, bis Python und Pygame Absturz ruft, weil die Rekursion Grenze von 1000 Rekursion ist übertroffen.

Hier ist ein schönes Beispiel für eine simple finite state machine von iminurnamez, die Sie verwenden können, um Szenen und Menüs zu implementieren.

Okay. Interessant. – There

Okay. Also ein paar Änderungen vorgenommen und es scheint für jetzt in Ordnung zu sein. – There

Problem: Jede Klasse hat eine andere Klasse angerufen und somit nie wirklich beendet. Z.B. 'Menu1(). Some_function: Menu2()'. Lösung: Lassen Sie eine Elternklasse angeben, welche Klassen angerufen werden sollen. Z.B. 'a = Menu1()' dann 'a = Menu2()'. – There

Fehler in der Pygame-Segmentierung: Problem mit Klassierung und Rekursion?
