unity3d - 如何在 Unity 中控制倾斜表面上的玩家相机/独立于 xyz 轴？

问题描述

我设法让我的玩家利用重力在圆柱体的内表面周围移动，但在尝试旋转相机环顾四周时出现了问题。

首先，有一个脚本通过将玩家推向圆柱体的内壁来模拟重力。该脚本还通过将玩家的“向上”方向更改为始终面向圆柱体的中心来保持玩家直立。我知道这会阻止我的玩家向上看，所以现在我只是在努力让他们向左看和向右看。

其次，当玩家位于圆柱体底部并与 Y 轴平行时，我可以毫无问题地左右看，因为相机使用 x 轴旋转（参见图像左侧的圆圈）。然而，当玩家围绕圆柱体的一侧移动时，即使它们未对齐，相机仍会尝试基于 X 轴旋转，从而导致相机无法准确旋转（参见图像右侧的圆圈），并且当玩家围绕圆柱体旋转 90 度时，根本无法旋转（我认为是由于重力使玩家保持垂直于圆柱体的侧面），并且在旋转 180 度时会反转。

我假设有两种可能的解决方案我无法成功实施：

忽略世界 xyz 轴'并相对于玩家的 xyz 旋转。
当你考虑到玩家围绕圆柱体的旋转和当前“左”方向的角度时，做一些数学计算来计算出正确的角度。

第一个解决方案的问题是我无法成功地旋转独立于世界 xyz 的玩家。我尝试将 Space.Self 添加到 Rotate() 方法但没有成功。第二个问题是数学让我害怕，到目前为止我已经设法避免四元数和欧拉角，所以我什至不知道如何开始弄清楚这一点。

如果有人遇到过类似的问题，我将不胜感激有关如何解决的任何见解或建议。

这是我控制播放运动/相机方向的代码和我的重力代码：
