Question

我包括了这个：

    if spirect.top > mcrect.top:
        spirect.move_ip(-3,0)
    if spirect.top < mcrect.top:
        spirect.move_ip(3,0)
    if spirect.left > mcrect.left:
        spirect.move_ip(0,-3)
    if spirect.left < mcrect.left:
        spirect.move_ip(0,3)

在我的主循环中让我的游戏中的蜘蛛向主角移动。在尝试这个之后，无论如何，蜘蛛（spirect）只是向一个方向移动。我该如何解决？所有相关代码：

你比较了蜘蛛和mc的top（y坐标），但是你改变了x坐标:)所以蜘蛛向错误的方向移动而且它不能停止因为它的top仍然不同于mc top：）

if spirect.top > mcrect.top:
    spirect.move_ip(0,-3) # before: (3,0)
elif spirect.top < mcrect.top:
    spirect.move_ip(0,3) # before: (-3,0)


if spirect.left > mcrect.left:
    spirect.move_ip(-3,0) # before: (0, 3)
elif spirect.left < mcrect.left:
    spirect.move_ip(3,0) # before: (0,-3)

但现在spider的移动速度与mc一样快，因此它们始终位于同一位置。更快mc或将spider放在远离mc

的位置

mc_speed = 6 # before: 3

if  pygame.key.get_pressed()[K_LEFT]:
    mcrect.move_ip(-mc_speed,0)
elif  pygame.key.get_pressed()[K_RIGHT]:
    mcrect.move_ip(mc_speed,0)


# use `if` instead of `elif`
if  pygame.key.get_pressed()[K_UP]:
    mcrect.move_ip(0,-mc_speed)
elif  pygame.key.get_pressed()[K_DOWN]:
    mcrect.move_ip(0,mc_speed)

pygame的。 Rect永远向一个方向移动？
