Python乌龟模块碰撞在最终级别不起作用

Question

我的项目有一些问题。我想要一个游戏，从右侧有 5 个 TIE 战士（敌人），你必须射击他们才能获得积分。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（用 45 次射击）。
我的问题是与老板打架。子弹如预期般与敌人相撞，但当涉及到boss战时，子弹只是无视boss。我试图修复碰撞，但我尝试过的似乎没有任何效果。
我知道使用课程会更容易，但这是一个学校项目，我们还没有学习课程，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。
感谢您提前回答。

尝试使用另一种方法来检查碰撞，我在大多数代码中都使用了这种方法，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()
