Pygame 跳跃动画不起作用 - 虽然走路是

Question

好的，所以我可以在主文件的左右添加行走动画，但是当我基本上复制/粘贴/更改名称以添加跳跃时，它不起作用。

我继续制作了我的主文件的副本，只是没有行走动画。我继续尝试只做跳跃动画，即使我复制了与行走相同的教程中的所有内容，它仍然不起作用。

从昨晚 8 点左右开始，我一直在努力解决这个问题。跳跃动画有不同的工作方式吗？ THE COPY 的代码见下文，因此没有行走动画。我没有出错，玩家可以左右行走，也可以跳跃。

如果玩家正在跳跃，您必须绘制player_jump 引用的Surface：

while run:
    # [...]

    screen.blit(bg_surface, (0, 0))
    player_rect.centery = player_movement
    if isJump:
        screen.blit(player_jump, player_rect)
    else:
        screen.blit(player_idle, player_rect)

    # [...]
