Keyboard Pygame鼠标/键盘控制条件

我有两个矩形（条纹），我想点击条纹用鼠标上下移动，然后用K_向上和K_向下键移动相同的条纹。使用我编写的代码，我可以用鼠标移动条纹，但按键同时移动两条条纹，而不是单独移动。我只是一个星期的程序员，请帮助

我将按如下方式构造代码：如果单击鼠标，并且

事件.pos

与条带冲突，则将该条带分配给变量（

selected\u stripe

），如果用户单击其他位置，则将其设置为

None

。只要鼠标按钮按下，还可以将

滚动

变量设置为

True

。在事件循环之外，您可以将所选条带的y位置设置为鼠标位置。对于向上键和向下键，您只需使用所选条带的

move

方法即可

selected_stripe = None
scrolling = True

while Running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            Running = False
        if event.type == pygame.MOUSEBUTTONDOWN:
            if event.button == 1:
                scrolling = True
                if stripe_1aa.collidepoint(event.pos):
                    selected_stripe = stripe1
                elif stripe_2aa.collidepoint(event.pos):
                    selected_stripe = stripe2
                else:
                    selected_stripe = None
        elif event.type == pygame.MOUSEBUTTONUP:
            scrolling = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_DOWN:
                if selected_stripe:
                    selected_stripe.move(0, 1)
            if event.key == pygame.K_UP:
                if selected_stripe:
                    selected_stripe.move(0, -1)

    if selected_stripe and scrolling:
        mouse_x, mouse_y = pygame.mouse.get_pos()
        selected_stripe.rect.y = mouse_y

欢迎来到SO！最好发布一个，因为这会让我们更容易帮助你。我发布了整个代码谢谢你的编辑。你的解决方案非常有效！非常感谢你教我这个方法，你真是棒极了！关于这个项目，我有很多问题（比如如何将条纹移动捕捉到网格），但我当然会尝试使用这个论坛作为我的最后手段。嗨，有没有可能在变量selected_stripe中添加另一个rect对象作为stripe1，但具有不同的y_位置和颜色，可以随stripe1移动（仅限）。我试过了，但没用我不知道你到底想做什么。请提供更多细节和最终目标。你试过使用元组或列表吗？用你的代码我只能移动一个rect对象。我需要附加多个矩形（与stripe1的x坐标相同）并将它们一起移动。目标是这样的：它是红绿灯协调图如果可以同时选择多个矩形，您可以尝试使用一个列表作为

selected\u stripe

s变量，并将所选条带附加到它。
