'Dodger'型游戏

Question

我正在尝试使用livewires和pygame编写游戏，在那里我有一个厨师（只有我有图像，哈哈），避免从天上坠落的岩石。岩石应该随机掉落。我希望它是一开始就有一块岩石落下，然后每当你成功躲开一块岩石时，另有两块岩石会掉落，直到你失去。到目前为止，我所拥有的厨师和一块石头正在坠落。然而，由于某些原因，如果精灵发生碰撞，或者如果岩石碰到屏幕底部，游戏就会结束，而不会像我告诉过的那样给游戏发送消息。我很困惑，看不到我做了什么。我知道我没有为2个岩石部分正确编码，但我甚至无法轻微运行。帮帮我！这是我现在有：

from livewires import games, color 
import random 

games.init(screen_width = 640, screen_height = 480, fps = 50) 


class Chef(games.Sprite): 

    image = games.load_image("chef.bmp") 

    def __init__(self): 
     super(Chef, self).__init__(image = Chef.image, 
            x = games.mouse.x, 
            bottom = games.screen.height) 

    def update(self): 
     self.x = games.mouse.x 

     if self.left < 0: 
      self.left = 0 

     if self.right > games.screen.width: 
      self.right = games.screen.width 

     self.check_catch() 

    def check_catch(self): 
     for pizza in self.overlapping_sprites: 
      if not self.bottom>games.screen.height: 
       self.end_game() 


class Rock(games.Sprite): 

    def update(self): 
     if self.bottom > games.screen.height: 
       new_rock=Rock(x=random.randrange(games.screen.width), 
           y=10, 
           dy=1) 
       games.screen.add(new_rock) 

    def end_game(self): 
     end_message = games.Message(value = "Game Over", 
            size = 90, 
            color = color.red, 
            x = games.screen.width/2, 
            y = games.screen.height/2, 
            lifetime = 5 * games.screen.fps, 
            after_death = games.screen.quit) 
     games.screen.add(end_message) 


def main(): 

    wall_image = games.load_image("wall.jpg", transparent = False) 
    games.screen.background = wall_image 

    the_chef = Chef() 
    games.screen.add(the_chef) 

    rock_image=games.load_image("rock.bmp") 
    the_rock=Rock(image=rock_image, 
        x=random.randrange(games.screen.width), 
        y=10, 
        dy=1) 
    games.screen.add(the_rock) 

    games.mouse.is_visible = False 

    games.screen.event_grab = True 
    games.screen.mainloop() 

main()

您已经声明end_game方法Rock class但你从Chef classcheck_catch方法调用它。
