Python turtle 模块碰撞在最终级别不起作用

Question

我的项目有问题。我想要一款游戏，右侧有 5 个 TIE 战士（敌人），你必须射击他们才能获得分数。在你达到 100 点后（出于测试原因在代码 5 中），一个老板来了，你需要杀死它（45 次射击）。
我的问题是boss战。子弹果然和敌人撞在了一起，但是打boss的时候，子弹就直接无视了boss。我试图修复碰撞，但似乎没有任何效果。
我知道使用类会更容易，但这是一个学校项目，我们还没有学习类，所以我们显然不能使用它们。对不起，如果代码有点杂乱无章，我只是一个正在学习编码的学生。
提前感谢您的回答。

尝试使用另一种方法来检查碰撞，我在我的大部分代码中都使用了它并且效果很好。

#you can edit the value here     \/ to change the radius of the collision detection
if bullet.xcor() - boss.xcor() < 10 and bullet.xcor() - boss.xcor() < 10:
                bosshit += 1
                bullet.setx(700)
                bullet.fd(0)
                bullet.clear()
                bullet.hideturtle()
