Ich bin neu in Python, Pygame und Programmierung im Allgemeinen. Ich versuche einen Asteroids-Klon zu erstellen, aber ich kann nicht herausfinden, wie ich mein Player-Sprite gleichzeitig bewegen und drehen lassen kann. Ich habe die Vector2D-Klasse von this answer (versucht, es für die Tastatur anstelle der Maus zu ändern), so dass mein Sprite sich dreht (es wird nicht in einem vollständigen Kreis drehen), aber jetzt wird es nicht bewegen. Ich versuche mit den Auf- und Ab-Tasten zu beschleunigen/zu verzögern und mit den Links- und Rechtspfeilen zu drehen. Ich möchte, dass das Schiff in die Richtung sieht, in die es sich bewegt.Ein Sprite in Pygame rotieren und verschieben
Hier ist der Code so weit:
