PictureBox 更改为与我想要的相反

所以我正在为我的编程课做一个第 2 季度的项目，我正在 Visual Studio 中制作一个游戏。我知道，它可能不适合游戏，但我真的没有时间将所有工作转移到 Unity 上。所以我的问题是，我设置了代码，这样当你按下空格键时，如果玩家（顺便说一句，我正在用图片和 GIF 做的所有这些）面向右侧，他会向右挥舞他的剑，如果他在左侧，他会向左摆动。有一个计时器，完成后，将播放器动画更改回空闲状态。我测试了一下，当他面向左侧并且我按下空间时，他向左摆动并向左结束。问题是，他在面对正确的时候做同样的事情。我已经尝试了我所知道的一切，而老师却忙于帮助其他人完全学习我的编码。有人可以帮我吗？
