我的海龟没有检测到输入，它可以越过边界

Question

所以基本上，我根本不能移动我的乌龟，即使它有功能。而且，当我可以的时候，当它到达边界时，它会继续前进。我试过移动函数的位置，但它不起作用。我已经设置了它的所有功能并且它们过去工作过，我不知道是什么让它们停止工作。此外，乌龟和边界之间的接触也没有任何作用。

  import turtle, os, math
    #setting up the dimensions of the screen + color

    wn = turtle.Screen()
    wn.screensize(500,500)
    wn.title("Mario vs the turtles")
    wn.bgcolor("white")
    border_pen = turtle.Turtle()
    border_pen.speed(0)
    border_pen.color("black")
    border_pen.penup()
    border_pen.setposition(-350,-350)
    border_pen.pendown()
    border_pen.pensize(3)
    for side in range (4):
        border_pen.fd(600)

我不知道是什么让他们停止工作

我很难相信这段代码曾经有效。这似乎是来自其他程序的 frankenpaste 比特，正在等待一场好的闪电风暴。例如：

 mario.ycor==simon.ycor
while simon.xcor<500 and simon.xcor>-500:
if mario.xcor==simon.xcor and mario.ycor==simon.ycor:
if mario.xcor<=border_pen.xcor and mario.ycor<=border_pen.ycor:

mario.xcor() 和 .ycor() 是方法，mario.xcor 和 .ycor 什么都不做。另外：

if  mario.setheading(180) and mario.forward (100):
    turtle.register_shape("marioleft.gif")
    mario.shape("marioleft.gif")

mario.setheading(180) 和 mario.forward(100) 总是返回 None，所以这永远不会发生。有很多设置逻辑，但没有真正的运行时循环。我已尽我所能将代码改写成可玩的游戏，尽管它可能不是您想要的游戏：

from turtle import Screen, Turtle, mainloop

FONT = ("Courier", 24, "normal")

def jump():
    screen.onkey(None, 'space')  # disable handler inside handler

    if mario.ycor() == 0:  # if mario isn't already in the air
            mario.forward(150)
            mario.backward(150)

    screen.onkey(jump, 'space')

def left():
    x = mario.xcor()

    if x > -250:
        mario.setx(x - 10)

def right():
    x = mario.xcor()

    if x < 250:
        mario.setx(x + 10)

def escape():
    screen.bye()

def reset():
    global hearts_mario

    mario.goto(0, 0)

    hearts_mario = 3
    score.write("Score: {} Hearts: {}".format(score_mario, hearts_mario), align="center", font=FONT)

# setting up the dimensions of the screen + color

screen = Screen()
screen.screensize(650, 650)
screen.title("Mario vs the turtles")

border_pen = Turtle()
border_pen.hideturtle()
border_pen.speed('fastest')
border_pen.pensize(3)

border_pen.penup()
border_pen.setposition(-275, -275)
border_pen.pendown()

for _ in range(4):
    border_pen.fd(550)
    border_pen.lt(90)

# score
score_mario = 0
hearts_mario = 3

score = Turtle()
score.hideturtle()
score.speed('fastest')

score.penup()
score.sety(300)
score.pendown()

score.write("Score: {} Hearts: {}".format(score_mario, hearts_mario), align="center", font=FONT)

# color of the turtle, speed, two variables for the position
mario = Turtle()
mario.hideturtle()
mario.shape("turtle")
mario.color('dark green', 'light green')
mario.speed('slowest')
mario.penup()
mario.setheading(90)
mario.showturtle()

simon = Turtle()
simon.hideturtle()
simon.shape("turtle")
simon.color('black', 'red')
simon.penup()
simon.setx(-250)
simon.showturtle()

# Main game loop

def game_loop():
    global hearts_mario

    if simon.xcor() < -250 or simon.xcor() > 250:
        simon.setheading(180 - simon.heading())

    simon.forward(10)

    if mario.distance(simon) < 5:
        hearts_mario -= 1
        score.undo()
        score.write("Score: {} Hearts: {}".format(score_mario, hearts_mario), align="center", font=FONT)

    if hearts_mario > 0:
        screen.ontimer(game_loop, 100)

screen.onkey(left, "Left")
screen.onkey(right, "Right")
screen.onkey(escape, "Escape")
screen.onkey(reset, "r")
screen.onkey(jump, "space")
screen.listen()

game_loop()

mainloop()
