pygame/python不会检测到精灵之间的碰撞

Question

即时尝试检测pacman和盒子之间的碰撞，但它不检测任何碰撞，任何帮助或建议？目前我试图创建一个实例列表，但没有奏效，我不知道还有什么要做。它也告诉我要增加更多的细节，但我真的不知道我可以添加要诚实，对不起

1 - 您需要更新moviment方法的顶部和左侧位置。看：

# 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 - 你必须与所有的框将verificate碰撞成环，验证

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

使用rect.collidelist测试如果吃豆子与在墙上的精灵列表中的墙壁精灵碰撞。只要没有检测到碰撞，它将返回-1
