当我的播放器接触地面时，如何让我的闲置 animation 播放

Question

所以我为我的播放器做了一个跳跃 animation，我一直想知道如何做到这一点，以便当我的播放器接触地面/平台时，它将停止播放我的跳跃 animation 并播放我的空闲 animation。我试图让它播放animation 当玩家按下空格键并且玩家的跌倒 > 0 但这会使 animation 变短，我也尝试使用计时器让 animation 播放一段时间，但这也没有用。 我只希望它在跳跃时播放 jump animation 并在它接触地面时停止播放。

我正在努力知道，这就是它正在做的事情： https://gyazo.com/5cfda577628e5596d033b11a7486bbf9?token=6f82939da2c6b2363232b3e3f379aa07

        collide = False
        for Platform in platforms:
            if playerman.get_rect().colliderect(Platform.rect):
                collide = True
                playerman.isJump = False
                playerman.y = Platform.rect.top - playerman.height
                if playerman.rect.right > Platform.rect.left and playerman.rect.left < Platform.rect.left - playerman.width:
                    playerman.x = Platform.rect.left - playerman.width
                if playerman.rect.left < Platform.rect.right and playerman.rect.right > Platform.rect.right + playerman.width:
                    playerman.x = Platform.rect.right
            else:
                if playerman.direction == "walk":
                    playerman.direction = "jump"

当玩家与平台发生碰撞时切换到“空闲”animation，当前 animation 为“跳跃”：

collide = False
for Platform in platforms:
    if playerman.get_rect().colliderect(Platform.rect):
        collide = True
        playerman.isJump = False
        
        if playerman.direction == "jump":
            playerman.direction = "idle":
