我不明白为什么 enemy/player 射击的弹药在他们死后不会消失 pygame
I cant figure out why the ammo the enemy/player is shooting doesnt dissapear after they die pygame
我正在尝试在我的游戏中进行 bossfight。 Boss 是一只向玩家发射弹丸的黄蜂。玩家在与boss战斗时，每隔一段时间就会获得额外的弹药。
唯一的问题是我不知道如何在bossfight后重置一切并让游戏正常继续。 Boss 弹丸继续掉落，但从与 Boss 死亡的位置不同的位置。
我在 bossfight 中使用了两个不同的 类：Boss 和 Projectile。我对玩家的射弹和敌人的射弹有不同的类。我会附上游戏的图片。

问题是以下代码块总是将 BossNow 重置为 True，即使在 boss 已经被打败之后也是如此。
if player.score >= 100:
bossNow = True
else:
bossNow = False
所以，你必须添加一些东西来防止这种情况发生。我会为此使用 BossDefeated 变量。
为了实现这一点，您必须进行以下更改：
1：通过在游戏循环之前添加以下行，将 BossDefeated 变量初始化为 False：
BossDefeated=False
2：通过将第一个代码块更改为以下内容，使 BossDefeated 变量生效：
if player.score >= 100 and not BossDefeated:
bossNow = True
else:
bossNow = False
3：在每次调用 WaspBoss.kill 后添加以下行，将打败 Boss 时设置的 BossDefeated 变量设置为 True：
BossNow=True
我们还需要在Boss.update的函数定义中添加下面这行，以获取BossDefeated的变化到全局范围内。
global BossDefeated

问题是以下代码块总是将 BossNow 重置为 True，即使在 boss 已经被打败之后也是如此。
if player.score >= 100:
bossNow = True
else:
bossNow = False
所以，你必须添加一些东西来防止这种情况发生。我会为此使用 BossDefeated 变量。
为了实现这一点，您必须进行以下更改：
1：通过在游戏循环之前添加以下行，将 BossDefeated 变量初始化为 False：
BossDefeated=False
2：通过将第一个代码块更改为以下内容，使 BossDefeated 变量生效：
if player.score >= 100 and not BossDefeated:
bossNow = True
else:
bossNow = False
3：在每次调用 WaspBoss.kill 后添加以下行，将打败 Boss 时设置的 BossDefeated 变量设置为 True：
BossNow=True
我们还需要在Boss.update的函数定义中添加下面这行，以获取BossDefeated的变化到全局范围内。
global BossDefeated
