Class player - 动画停止第一帧
Class player - Animation stop first frame
快速提问。我的播放器 Class 运行良好。除了一个小细节。这是 class:

由于要更新Player的精灵，我需要调用"load_sprite"函数，导致动画不断被调用。因此，不会出现相同的动画，而是在第一帧保持静止。那我怎么解决呢？
编辑：修改了脚本，包括 for 循环。如果您看到，我修改了组，改为使用 Batch 和 OrderedGroup。这样我们就可以清楚的看到我遇到的问题了。
我遇到的问题是因为调用 pyglet.sprite.Sprite 是为了更新执行的动画。然而，同时这样做，由于pyglet.sprite.Sprite.
的不断调用，动画并没有完全显示出来。
首先，您可以通过设置精灵的 image 属性来更改精灵的动画，而不用创建新的精灵实例。其次，只有在真正需要时才更改它的动画。那就是方向改变的时候。
我添加了一个简单的示例（伪）代码来大致说明我的意思。
