我遇到了麻烦，我正试图在我的比赛中打开大门。我正在使用 pygame 和 pytmx，我已经建立了一个用房间制作的关卡，并且在每个房间中我都有一个使用 pytmx 的渲染器，我想要实现的是例如在 0 级玩家必须移动到一扇门打开它进入关卡 1，我的目标是在玩家敲门时启动并绘制动画。
我试图让我的 Door 对象（他的父对象是 pygame Sprite 类）更新，它有点工作，但当然对象被修改和显示，但是平铺的地图对象也停留在地图的后面，所以我试图只是不初始化我在瓷砖地图中的对象，但如果是这样，门根本不会咬。然后我尝试修改平铺对象图像并重新加载我的渲染但仍然无法正常工作，你们中的任何人有任何想法吗？
下面是部分代码，方便大家理解

所以现在我想做的是使用动画平铺对象并从 tmx 数据启动动画，但我什至不明白如何在第一次渲染时启动动画。
预先感谢您的回答。
