Question

问题出在#num注释更改部分。应该在数字周围画一个绿色框，然后在该位置写一个新的。首先，我测试了#AP，它运行良好。因此，我添加了#HP，但是由于某种原因它不起作用，#AP也停止了。我没有收到错误消息，尽管查看了但没有看到问题。

import turtle
import winsound
import os
import time
#screen
wn = turtle.Screen()
wn.bgcolor("green")
wn.title("game")
hp=100
ap=10

def song1():
    winsound.PlaySound("sound1", winsound.SND_FILENAME)


#menu
time.sleep(2)
men_pen = turtle.Turtle()
men_pen.speed(0)
men_pen.color("black")
men_pen.penup()
men_pen.setposition(-1000,-200)
men_pen.pensize(4)
men_pen.pendown()
men_pen.fd(2500)

#menu text
men_pen.penup()
men_pen.setposition(-625,-265)
men_pen.pendown()
men_pen.write("HP=",True,font=('terminal',18, 'bold'))

有一种更简单的方法可以解决此问题。可以使用乌龟的.clear()（或.undo()）方法来代替文本，而不用背景彩色矩形覆盖文本，然后再重新重写：

from turtle import Screen, Turtle
import time

FONT = ('terminal', 18, 'bold')

def changeap():
    ap_pen.clear()
    ap_pen.write(ap, font=FONT)

def changehp():
    hp_pen.clear()
    hp_pen.write(hp, font=FONT)

# screen
screen = Screen()
screen.setup(1300, 650)
screen.bgcolor("green")
screen.title("game")

hp = 100
ap = 10

# menu
men_pen = Turtle(visible=False)
men_pen.speed('fastest')
men_pen.pensize(4)

men_pen.penup()
men_pen.setposition(-650, -200)
men_pen.pendown()
men_pen.fd(1300)

# num changers
# AP
ap_pen = Turtle(visible=False)
ap_pen.speed('fastest')
ap_pen.penup()
ap_pen.setposition(-560, -312)

# HP
hp_pen = Turtle(visible=False)
hp_pen.speed('fastest')
hp_pen.penup()
hp_pen.setposition(-560, -265)

# menu text
men_pen.penup()
men_pen.setposition(-625, -265)
men_pen.write("HP=", True, font=FONT)

hp_pen.write(hp, font=FONT)

men_pen.setposition(-625, -312)
men_pen.write("AP=", True, font=FONT)

ap_pen.write(ap, font=FONT)

men_pen.setposition(-499, -240)
men_pen.write("William", True, font=FONT)

hp = 20
ap = 1000

time.sleep(5)
changeap()
time.sleep(5)
changehp()

screen.mainloop()

如何在Python Turtle中覆盖和重写文本？
