Pygame 初学者，播放器动画尽管按照教程做了但还是不工作
Pygame beginner, player animation not working despite doing it by the tutorial
第一次与 Pygame 一起完成学校作业，我正在与我的项目成员一起学习教程（教程 link https://youtu.be/AY9MnQ4x3zk）。
问题是，尽管遵循了“为玩家设置动画”的教程，但我的角色（在游戏和代码中名为“Marko”）没有播放他的动画。当我开始游戏时，角色停留在它的第一帧动画上。我创建了一个 3 帧动画并将帧作为单独的 png 文件。到目前为止，游戏本身是可行的（它处于非常初级的水平，到目前为止只生成了几个生成的敌人、碰撞和介绍屏幕），但是动画让我和我的项目组绞尽脑汁好几天了。到目前为止还没有通过谷歌搜索或在这里搜索找到解决方案。
同样在“# Marko's animations”部分，“marko”变暗，当将鼠标悬停在其上时，它显示“”（可变）marko：Surface - “marko”未访问 Pylance”“

marko 是全局命名空间中的一个变量。您必须使用 global statement 来更改函数内全局命名空间中的变量：
def marko_animation():
global marko # <---
global marko_index
if markoSurface.bottom < 955:
marko = marko_jump
else:
marko_index += 0.1
if marko_index >= len(marko_run):
marko_index = 0
marko = marko_run[int(marko_index)]
