turtle 中的主菜单

Question

谁能给我解释一下，为什么无论您点击哪里，程序都会给出 "Else" 响应，以及为什么它会不断重复直到崩溃？我没有 for 循环或 while 循环，所以我不明白。可能是 onscreenclick() 或 listen() 函数吗？另外，我知道部分菜单不在屏幕上的问题。我打算在检查它的效果后修复它。

import turtle

pen = turtle.Turtle()
pen.speed(0)

#Creating Menu option buttons
def button(length):
    for i in range(4):
        pen.forward(length)
        pen.left(90)

def column(n, length):
    pen.left(270)
    for i in range(n):
        button(length)
        pen.forward(length)
    pen.penup()
    pen.left(90)
    pen.forward(n * length)
    pen.left(180)
    pen.pendown()

column(5, 100)

#Menu Options
pen.penup()
pen.goto(8, -46)
pen.write("START GAME!", font=("Arial",12,"normal"))

pen.penup()
pen.goto(6, -145)
pen.write("RULES", font=("Arial",12,"normal"))

pen.penup()
pen.goto(3, -248)
pen.write("HIGH SCORE", font=("Arial",12,"normal"))

pen.penup()
pen.goto(4, -343)
pen.write("FAQ", font=("Arial",12,"normal"))

pen.penup()
pen.goto(3, -450)
pen.write("QUIT GAME", font=("Arial",12,"normal"))

#Making options clickable
def btnclick(x,y):
    if x > 0 and x < 101 and y > 0 and y < -101:
        print("Start Game")
        print(x, y)
        turtle.clearscreen()
    elif x > 0 and x < 101 and y > 101 and y < -201:
        print("Rules")
        print(x, y)
        turtle.clearscreen()
    elif x > 0 and x < 101 and y > 201 and y < -301:
        print("Highscore")
        print(x, y)
        turtle.clearscreen()
    elif x > 0 and x < 101 and y > 301 and y < -401:
        print("Hi")
        print(x, y)
        turtle.clearscreen()
    elif x > 0 and x < 101 and y > 401 and y < -501:
        print("Hi")
        print(x, y)
        turtle.clearscreen()
    elif x > 0 and x < 101 and y > 501 and y < -601:
        print("Hi")
        print(x, y)
        turtle.clearscreen()
    else:
        print("Click One Of The Options!")
        print(x, y)
        btnclick(x, y)

turtle.onscreenclick(btnclick, 1)
turtle.listen()

turtle.done()

您忘记了减号，您必须将

中的 < 替换为 >

y > 0 and y < -101:

y > 101 and y < -201:

y > 201 and y < -301:

y > 301 and y < -401:

y > 401 and y < -501:

y > 501 and y < -601:

应该是。

y < 0 and y > -101

y < -101 and y > -201

y < -201 and y > -301

# etc.

或更短

0 > y > -101

-101 > y > -201

-201 > y > -301

# etc.

编辑： 也许你应该在某些地方使用 >=，因为旧代码不适用于 y == -101、y == -201 等.

0 > y >= -101

-101 > y >= -201

-201 > y >= -301

etc.

全功能
