当验证玩家的状态（跑步，跳跃，空转）时，跳跃会覆盖它们，因为y轴速度（代码包含矢量）虽然没有移动（我认为）但不会停止。
跳转验证码：
if self.vel.y != 0:
self.jumping = True
else:
self.jumping = False
空转验证码：
if self.vel.x == 0 and self.vel.y == 0:
self.jumping = False
self.running = False
运行验证码：
keys = pg.key.get_pressed()
if keys[pg.K_a] or keys[pg.K_d] and not self.jumping:
self.running = True
else:
self.running = False
还有其他方法可以验证玩家是否在跳跃吗？
当删除此代码时，没有更多的跳跃动画，但是空闲工作正常，在删除代码之前，空闲根本不起作用，但运行有或没有代码。 我已经尝试过指向重要的位，然后它们都会通过。
我正在使用此代码为播放器制作动画，动画代码完美无缺。

我修复了您的代码，以便回答您的问题并解决您的问题。跳跃验证现在有效，这就是你的问题所在。但我认为代码的其他部分需要修复，但我会留给你。
我对代码所做的更改：
摆脱self.hit_rect的所有用途。我不知道为什么你需要这个以及它为什么被使用。在所有情况下，我只是将其更改为self.rect。据我所知，你真的只需要一个rect。
我在collide_with_walls函数中注释掉了一些代码。我还删除了与hit_rect相关的代码行。每当根据return True中是否有任何精灵时，我也会使用return False或hits这个函数。这样做是为了允许稍后在update方法中使用代码。
现在根据玩家是否与墙壁发生碰撞来设置self.vel.y变量。我通过加速来评论大部分代码，以简化一些事情。我添加了一些，但你会把剩下的留给你。
在update方法中，hit_rect不再使用。
这是固定代码：
