pygame飞机大战之无敌主角与效率过高的敌机

正与标题所说，我做游戏是卡了两个bug：
一、主角无法被消灭
二、敌机出现的概率太高，小型机还好，中型机出现的机率比小型机低一点，大型机一下子竟然出线两三个
想请教各位是怎么回事，以下是主体代码：

I'm sorry, I cannot provide information or predict events that have occurred after my last knowledge update in September 2021. Please consult reliable sources for current information and events.

球一个最佳答案谢谢啦！这对我非常重要！{:10_254:}{:10_254:}{:10_254:}

根据您提供的代码，我发现了两个问题：

1. 主角无法被消灭：这是因为在检测我方飞机是否被撞的部分，您将每个击中的敌机的active属性设置为False，但是没有将我方飞机的active属性设置为False。为了解决这个问题，您需要在enemies_down条件下将我方飞机的active属性设置为False。

2. 敌机出现的概率太高：这是因为在reset()方法中，您为敌机设置了随机的初始位置。这可能导致敌机在游戏开始时就出现在屏幕上。为了解决这个问题，您可以在reset()方法中为敌机设置一个更大的初始top值，以便它们在游戏开始时不会立即出现在屏幕上。

以下是修改后的代码：

在main()函数中，修改检测我方飞机是否被撞的部分：

enemies_down = pygame.sprite.spritecollide(me, enemies, False)
if enemies_down:
me.active = False
for e in enemies_down:
e.active = False

在SmallEnemy、MidEnemy和BigEnemy类的reset()方法中，增加更大的初始top值：

# SmallEnemy
def reset(self):
self.active = True
self.rect.left, self.rect.top = randint(0, self.width - self.rect.width), randint(-5 * self.height, 0) - randint(0, 100) - self.height

# MidEnemy
def reset(self):
self.active = True
self.rect.left, self.rect.top = randint(0, self.width - self.rect.width), randint(-10 * self.height, -self.height) - randint(0, 100) - self.height

# BigEnemy
def reset(self):
self.active = True
self.rect.left, self.rect.top = randint(0, self.width - self.rect.width), randint(-15 * self.height, -5 * self.height) - randint(0, 100) - self.height

这些修改应该可以解决您提到的问题。如果您还有其他问题，请随时告诉我。

无敌应该是碰撞出问题了，第二个问题你可以调一调概率？
