基本上我要做的就是使用Python的海龟模块创建一个双人游戏。底部有两只乌龟是玩家，顶部有两个圆圈作为检查站。一只乌龟应该在两个检查站之间来回走动 - 这只乌龟是目标。底部海龟向目标射击圈。
我的问题：
注意：代码的某些部分可能会造成混淆和/或不需要。
以下是代码：

下面是我对你的代码的修改，让它基本上只是玩游戏 - 它仍然需要工作才能成为一个完成的程序。
from turtle import Turtle, Screen
FONT = ("Arial", 32, "bold")

enemy.backward(10)

enemy.forward(10)

yertle.backward(10)
def k4():
yertle.forward(10)
def k5(): # enemy shoot
bullet.color("red")
bullet.goto(enemy.position())
bullet.showturtle()
bullet.forward(430)
if bullet.distance(runner) < 10:
magic_marker.write("Game Over", align="center", font=FONT)
bullet.hideturtle()
def k6(): # yertle shoot
bullet.color("blue")
bullet.goto(yertle.position())
bullet.showturtle()
bullet.forward(430)

您的代码有错误（您的评论也是如此）但我的主要建议是查看海龟文档以查看您可以使用的所有功能 - 在编写游戏时，您需要知道乌龟可以做什么。
我把子弹改成了一个共同的子弹 - 当你完成它们时，乌龟不会消失，所以这似乎更好地用于资源。但是，它也有问题。如果继续使用单个子弹模型，则需要将触发事件互锁以防止重叠。如果您使用相同的多个子弹，则需要添加更多ontimer个事件，例如runner用于控制其动作。
