我正在尝试使用刚体和 Cinemachine 实现 3D、第三人称角色移动。角色应该能够在地面和天花板上以及在墙壁上行走（面对正 X 轴时，只能在左右墙壁上行走）。
我通过向刚体添加/更改恒定力来实现这一点，以更改重力方向并在 x 上旋转角色上下，z 左右旋转角色。
CinemachineBrain 将 World Up Override 设置为 Characters 变换，CinemchineFreeLook 绑定模式设置为“Simple Follow with World Up”。这让摄像机/电影机的轨道相对于角色的旋转进行旋转。
现在我已经在我的 PlayerMovement 脚本中实现了 4 种方法，一种用于每个重力方向（上、下、左、右），它们中的每一个都基本相同，只是改变了旋转和重力。
MoveUp() 和 MoveDown() 方法按预期工作。
但我无法让 MoveLeft() 和 MoveRight() 方法工作。
问题是角色在添加摄像机角度时无法进行 360 度旋转（此处在 x 轴上），但在面对正或负 x 时只能进行 180 度旋转（感觉就像在 y 上有一堵看不见的墙轴。
我以某种方式期望 Cinemachine / the + Camera.main.transform.eulerAngles.x; 是这里的问题，但我无法弄清楚它到底是什么。
这是我在 Unity / 游戏开发中的第一个项目 - 所以我希望我提供了所有必要的信息。
感谢您的回答。
这是我的脚本：
（我按照本教程实现了基本运动并将其更改为使用刚体：https ://youtu.be/4HpC--2iowE ）
