图像不动？

Question

我正在做一个小游戏。我有一个主菜单，有两个按钮，如果有人按下教程按钮，屏幕将填充黑色，屏幕上会出现一个图像。我希望移动这个图像，尽管我放在键盘指令和它应该移动多少它只是不移动。没有移动hi_image的图像。

您没有更新菜单位置，只是x。你需要更新实际的菜单位置

    if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_UP:
            hi_position[1] -= 10
        if event.key == pygame.K_DOWN:
            hi_position[1] += 10
        if event.key == pygame.K_RIGHT:
            hi_position[0] += 10
        if event.key == pygame.K_LEFT:
            hi_position[0] -= 10
