乌龟清除屏幕

Question

我不知道如何去掉黑色箭头，如果你能帮忙就太好了！谢谢，如果你有任何其他修改来使游戏更好，那也太棒了！再次感谢！

它说我需要写更多的细节，所以我会继续打字，希望我有足够的字数来写。这附近应该不错

import math
import random

score = 0
print ("\n" * 40)
print("Welcome Player, I Hope You Have What it Takes to be the Next WARLORD BOSS")
print("Enemies Killed:\n0")

#Title
t=turtle.Pen()
t.pencolor("magenta")
t.hideturtle()
t.penup()
t.setposition(-300,350)
t.write("Catch 40 turtles for a suprise  ( ͡° ͜ʖ ͡°)", font=("Verdana", 18))

#Tip
text=turtle.Pen()
t.pencolor("magenta")
t.hideturtle()
turtle.clear()
t.penup()
t.setposition(-100, -350)
t.write("TOUCH THE EDGES, I DARE YOU", font=("Verdana", 18))```



#Set up screen
wn = turtle.Screen()
wn.bgcolor("dim gray")
wn.title("EXEXEXEXEEXXEXEXE HACK COMMENCING␀␀␀␀␀")

Answer 1

这段代码是你的问题：

text=turtle.Pen()
t.pencolor("magenta")
t.hideturtle()
turtle.clear()
t.penup()
t.setposition(-100, -350)
t.write("TOUCH THE EDGES, I DARE YOU", font=("Verdana", 18))

您复制并粘贴但忘记将 t. 更新为 text. 此外，turtle.clear() 没有意义，因为它完全指的是另一只乌龟：

text = turtle.Pen()
text.hideturtle()
text.pencolor("magenta")
text.penup()
text.setposition(-100, -350)
text.write("TOUCH THE EDGES, I DARE YOU", font=("Verdana", 18))
