这段代码有什么问题？如果有，如何解决？
整个项目可在此处下载：https://github.com/Some-T/FirstPersonController-CSharp
项目已设置相关的碰撞体和刚体！
有人建议我使用shapecast，但我认为可能不正确？我看不出来这怎么能行，因为我的玩家没有添加角色控制器组件？
总的来说，我该如何防止我的第一人称角色控制器像上面指定的视频中一样穿过墙壁？
经过进一步的研究，我发现了以下内容：
答案是使用：
https://docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html 作为快速修复。
但是，为了完美无缺，要使用：
https://docs.unity3d.com/ScriptReference/Rigidbody-velocity.html
至于如何在C#中实现，我不太确定，但这是我在bolt asset中拍摄的截图。
目前，我使用速度使运动正常工作，但它不起作用，我不确定为什么？因此，现在我的问题是如何使用速度使运动正常工作？我在FirstPersonController.cs中添加了一条线，使用速度移动角色：rb.velocity = new Vector3(HorizontalInput, 0, VerticalInput) * speed; 所以我唯一的问题和问题现在是我的玩家不朝着我玩家上的相机面向的方向移动，所以我不确定如何总体修复这个特定的问题？
