pygame/python erkennt keine Kollision zwischen Sprites

Question

ich versuche eine Kollision zwischen Pacman und den Boxen zu erkennen, aber keine Kollisionen, irgendwelche Hilfe oder Ratschläge? Im Moment habe ich versucht, eine Liste von Instanzen zu erstellen, aber das hat nicht funktioniert, ich weiß nicht, was ich sonst tun soll. auch sein sagt mir mehr Details hinzufügen, aber ich weiß nicht wirklich, was ich ehrlich zu sein hinzufügen kann, sorry

Answer 1

1 - Sie müssen die obere und linke Position bei Moviment-Methode aktualisieren. aussehen:

# move pacman 
def movement(self): 
    pressed= pygame.key.get_pressed() 
    if pressed[pygame.K_UP]: 
     self.y -= 2 
    if pressed[pygame.K_DOWN]: 
     self.y += 2 
    if pressed[pygame.K_LEFT]: 
     self.x -= 2 
    if pressed[pygame.K_RIGHT]: 
     self.x += 2 
    self.rect.left = self.x 
    self.rect.top = self.y 

2 - Sie haben die Kollision in Schleife verificate, zur Verifikation mit allen Boxen

for row in boundaries: 
    #y co ordinate 
    by=by+16  
    for n in row: 
     #x co ordinate 
     n=n-1 
     bx=n*16 
     box = boxcollisions(bx, by) 
     box_list.append(box) 
     box.draw(screen) 
     if pygame.sprite.collide_rect(sprite, box): 
      print("collided") 

Answer 2

Verwenden rect.collidelist zu testen, ob Pacman mit einer Wand von Sprites in Ihrer Wand Sprites Liste zu kollidieren. Es wird -1 zurückgegeben, solange keine Kollision erkannt wird.
