python海龟如果出错

我想用海龟和关卡制作蟒蛇游戏。所以，我检查了分数来决定用户的级别，但是，当程序运行[如果语句]时，我已经做的乌龟的移动会很慢。我不知道这个错误的原因以及如何解决。我需要你的帮助

def level():
global speed
if 0 <= score < 5:
    mypen.penup()
    mypen.hideturtle()
    mypen.setposition(-290, 310)
    levelstring = "level: 1"
    mypen.write(levelstring, False, align="left", font=('Consolas', 15, 'bold'))
    speed += 1
if 5 <= score < 10:
    mypen.penup()
    mypen.hideturtle()
    mypen.setposition(-290, 310)
    levelstring = "level: 2"
    mypen.write(levelstring, False, align="left", font=('Consolas', 15, 'bold'))
    speed += 2
elif 10 <= score:
    exit()

下面是我根据您提供的代码扩展的工作示例。它在每一个分数和每一个级别上加速了自动机。看看它是否按照您的意愿运行：

from turtle import Turtle, Screen
from random import randint

FONT = ('Consolas', 15, 'bold')

def check_level():
    global speed, level

    score_pen.undo()
    score_pen.write("Score: %s" % score, False, align='right', font=FONT)

    if 0 <= score < 5:
        speed += 1
        level = 1
    elif 5 <= score < 10:
        speed += 3
        level = 2
        alex.speed('fastest')
    elif score >= 10:
        screen.bye()

    level_pen.undo()
    level_pen.write("Level: %s" % level, False, align='left', font=FONT)

def move_alex():
    global score

    alex.forward(speed)

    #boundary checking
    if alex.xcor() > 300 or alex.xcor() < -300:
        alex.right(180)

    if alex.ycor() > 300 or alex.ycor() < -300:
        alex.right(180)

    # boundary checking
    if ts.xcor() > 300 or ts.xcor() < -300:
        ts.right(180)

    if ts.ycor() > 300 or ts.ycor() < -300:
        ts.right(180)

    # collision.checking
    if ts.distance(alex) < 20:
        score += 1
        check_level()

        alex.hideturtle()
        alex.setposition(randint(-300, 300), randint(-300, 300))
        alex.showturtle()

    screen.ontimer(move_alex, 100)

def move_right():
    screen.onkey(None, 'Right')
    ts.right(45)
    screen.onkey(move_right, 'Right')

def move_left():
    screen.onkey(None, 'Left')
    ts.left(45)
    screen.onkey(move_left, 'Left')

def move_forward():
    screen.onkey(None, 'Up')
    ts.forward(speed * 1.25)
    screen.onkey(move_forward, 'Up')

screen = Screen()
screen.setup(660, 660)

score = 0
level = 1
speed = 5

# Draw the score
score_pen = Turtle(visible=False)
score_pen.penup()
score_pen.setposition(290, 310)
score_pen.write("Score: %s" % score, False, align='right', font=FONT)

level_pen = Turtle(visible=False)
level_pen.penup()
level_pen.setposition(-290, 310)
level_pen.write("Level: %s" % level, False, align='left', font=FONT)

alex = Turtle('square', visible=False)
alex.speed('normal')
alex.penup()
alex.setheading(45)
alex.setposition(randint(-300, 300), randint(-300, 300))
alex.showturtle()

ts = Turtle('turtle')
ts.speed('fastest')
ts.penup()

screen.onkey(move_right, 'Right')
screen.onkey(move_left, 'Left')
screen.onkey(move_forward, 'Up')

move_alex()
screen.listen()
screen.mainloop()

这只是一个几乎不可玩的游戏的示例-显然需要努力才能完成它，并使其像蛇一样。

寻求调试帮助的问题此代码为什么不起作用？必须包括所需的行为、特定的问题或错误以及在问题本身中重现这些问题所需的最短代码。没有明确问题陈述的问题对其他读者没有用处。请参阅：。您发布的代码不可运行，因此也不可调试。请发布错误。如果您搞乱了turtles。。你会得到追踪系统的毒液，告诉你有些东西有毒。修正代码！并开始使用编辑器，例如IDLE、IPyton或komodo edit！对不起，这是我第一次发布代码，整个代码太长，无法发布。所以，我不知道如何显示我的错误代码
