当我运行我的代码并用空格键将乌龟向上移动时，所有应该移动的障碍物都停止移动。是什么导致了问题，我该如何解决？

我不知道是什么导致了这个问题，我试过谷歌搜索但找不到任何东西。由于这是我尝试 Python 或一般编程的第一周，我不知道我做错了什么。

一个问题是你的水平运动是由一个while True:循环控制的，不同步，但你的垂直运动是由一个键盘事件同步控制的。我们需要通过用事件替换你while True:的ontimer()事件来使两个动作同步。这是我对您的代码的完整修改，并出于示例目的进行了一些简化：

from turtle import Screen, Turtle
from random import choice, randrange

COLORS = ["red", "green", "yellow", "blue", "purple", "pink"]

PLAYER_SPEED = 50

GRAVITY = 3

NUMBER_OBSTACLES_UPPER = 2
NUMBER_OBSTACLES_LOWER = 2

# movement
def playerup():
    screen.onkeypress(None, 'space')  # disable handler inside handler

    player.sety(player.ycor() + PLAYER_SPEED)

    if player.ycor() > 287:
        player.speed('fastest')
        player.sety(287)
        player.speed('slowest')

    screen.onkeypress(playerup, 'space')

# collision
def hit(t1, t2):
    xdistance = abs(t1.xcor() - t2.xcor())

    if xdistance >= 20:
        return False

    ydistance = abs(t1.ycor() - t2.ycor())

    return ydistance < 130

# border
def fall():
    return player.ycor() < -300

def ceiling():
    return player.ycor() > 300

# main program loop
def move():
    global points, obstacle_speed_upper, obstacle_speed_lower

    player.sety(player.ycor() - GRAVITY)

    for obstacle in obstacles_upper:
        obstacle.setx(obstacle.xcor() - obstacle_speed_upper)

        if obstacle.xcor() < -270:
            obstacle.hideturtle()
            obstacle.setposition(randrange(230, 300), randrange(140, 190))
            obstacle.showturtle()
            obstacle_speed_upper += 1

            points += 1
            scoreboard.clear()
            scoreboard.write(points, font=('Arial', 30,))

        if hit(player, obstacle):
            player.hideturtle()
            gameover.write("Game Over", align='center', font=('Arial', 50,))
            return

    for obstacle in obstacles_lower:
        obstacle.setx(obstacle.xcor() - obstacle_speed_lower)

        if obstacle.xcor() < -270:
            obstacle.hideturtle()
            obstacle.setposition(randrange(230, 300), - randrange(160, 190))
            obstacle.showturtle()
            obstacle_speed_lower += 1

            points += 1
            scoreboard.clear()
            scoreboard.write(points, font=('Arial', 30,))

        if hit(player, obstacle):
            player.hideturtle()
            gameover.write("Game Over", align='center', font=('Arial', 50,))
