很多游戏都会给玩家多次尝试的机会，因此我们也添加这样一个功能，玩家总共会有3次机会，在游戏界面的右下角我们通过显示多少个小飞机提示玩家还剩下多少次机会。

有多次机会，就意味着我们的飞机可以reset() 复活，我们增加一个 reset() 方法，

def reset(self):
                    self.rect.left, self.rect.top = \
                                    (self.width - self.rect.width) // 2, \
                                    self.height - self.rect.height - 60
                    self.active = True

然后我们有3次机会，我们就需要在main模块中 加多一个 life\_num 的变量，表示生命数量

# 生命数量
            life_image = pygame.image.load("images/life.png").convert_alpha()
            life_rect = life_image.get_rect()
            life_num = 3

# 绘制剩余生命数量
                            if life_num:
                                    for i in range(life_num):
                                            screen.blit(life_image, \
                                                        (width-10-(i+1)*life_rect.width, \
                                                         height-10-life_rect.height))

这里的话，有一个小细节，就是每次我方飞机牺牲后，你在诞生的位置恰好有一个敌机，那么会直接导致我方飞机直接挂掉，因此，我们需要设定每次诞生有3秒钟的安全期，做法其实也不难。

我们只需要在 Myplane 类中加入一个属性，命名为 invincible ，在每次碰撞时先检测该属性的值。

最后，我们来写结束画面，游戏结束画面会显示历史最高分和此次分数，并提供玩家两个选择：重新游戏 或者 退出游戏。

历史最高分是存放在 record.txt 文件中的。

# 用于阻止重复打开记录文件
            recorded = False
    
            # 游戏结束画面
            gameover_font = pygame.font.Font("font/font.TTF", 48)
            again_image = pygame.image.load("images/again.png").convert_alpha()
            again_rect = again_image.get_rect()
            gameover_image = pygame.image.load("images/gameover.png").convert_alpha()
            gameover_rect = gameover_image.get_rect()

# 绘制游戏结束画面
                    elif life_num == 0:
                            # 背景音乐停止
                            pygame.mixer.music.stop()
    
                            # 停止全部音效
                            pygame.mixer.stop()
    
                            # 停止发放补给
                            pygame.time.set_timer(SUPPLY_TIME, 0)
    
                            if not recorded:
                                    recorded = True
                                    # 读取历史最高得分
                                    with open("record.txt", "r") as f:
                                            record_score = int(f.read())
    
                                    # 如果玩家得分高于历史最高得分，则存档
                                    if score > record_score:
                                            with open("record.txt", "w") as f:
                                                    f.write(str(score))
    
                            # 绘制结束画面
                            record_score_text = score_font.render("Best : %d" % record_score, True, (255, 255, 255))
                            screen.blit(record_score_text, (50, 50))
    
                            gameover_text1 = gameover_font.render("Your Score", True, (255, 255, 255))
                            gameover_text1_rect = gameover_text1.get_rect()
                            gameover_text1_rect.left, gameover_text1_rect.top = \
                                             (width - gameover_text1_rect.width) // 2, height // 3
                            screen.blit(gameover_text1, gameover_text1_rect)
    
                            gameover_text2 = gameover_font.render(str(score), True, (255, 255, 255))
                            gameover_text2_rect = gameover_text2.get_rect()

至此，我们的飞机大战游戏就完成了，大家一起来玩自己做的游戏吧！

            self.active = True
            self.rect.left, self.rect.bottom = \
                            randint(0, self.width - self.rect.width), -100

至此，Pygame 的内容就讲解完毕了。

至此，《零基础入门学习Python》的课程讲解也完毕了。

接下来有新的更高级的课程哦。
