python - pygame/python 不会检测 Sprite 之间的碰撞

Question

我试图检测 pacman 和盒子之间的碰撞，但它没有检测到任何碰撞，有什么帮助或建议吗？目前我尝试创建一个实例列表，但没有成功，我不知道还能做什么。它还告诉我添加更多细节，但说实话，我真的不知道可以添加什么，抱歉

1 - 您需要更新运动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 - 您必须在循环中验证碰撞，以验证所有框

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")
