如果有人愿意帮助我解决两个简单的问题(令人恼火的是，我找不到解决方案(，我将永远感激。我已经从互联网上尝试了几种解决方案，但它们似乎给我带来了更多的错误。
从本质上讲，我有一个2d Platformer，可以让你左右移动，跳跃和射击。然而，当你向右移动，然后跳跃时，它会朝相反的方向面向你[向左移动和跳跃效果非常好]。我认为这与"；DeprecationWarning：需要一个整数(获取的类型为float(。不赞成使用int隐式转换为整数"错误，但我可能错了。一旦你向右移动并跳跃，它朝着相反的方向，子弹也会朝着"右"方向移动，尽管精灵看起来面向窗口的左侧。如果任何愿意帮助我的人在解决这个问题时遇到困难，请联系我，我会尽我所能提供帮助，同时我也会自己解决。非常感谢。Anthony
请，如果有人能看看我的代码并指导我如何解决这个问题，我将再次永远感激。

此问题是由按下SPACE时设置player.right = False和player.left = False引起的。由于方向信息存储在player.right和player.left中，因此信息将丢失。跳转时保持player.right和player.left的状态：
if not (player.isJump):
if keys[pygame.K_SPACE]:
player.isJump = True
# player.right = False <--- DELETE
# player.left = False <--- DELETE
player.walkCount = 0
