前言
这是以前写的人物控制器(包含第一人称、第三人称、漫游视角)，这里做个记录，方便后续参考使用.
实现
模型使用官方的，操作使用鼠标右键控制视角，键盘WASD、Shift控制人物移动.
切换到漫游视角(God)时，有BUG，待修复.
人物控制：
/// <summary>/// 第三人称.人物移动操作./// </summary>private void MoveUpdate_ThirdController(){//按住左SHIFT 加速.if (Input.GetKey(KeyCode.LeftShift)){isRun = true;}else{isRun = false;}//按下了 W A S D.if (v != 0 || h != 0){if (isRun) //执行奔跑动画.{m_Animator.SetBool("Run", true);}else //执行行走动画.{m_Animator.SetBool("Run", false);m_Animator.SetBool("Walk", true);}float rotY = playerCamera.transform.rotation.eulerAngles.y;//摄像机世界坐标前方.Vector3 dir = new Vector3(h, 0, v); //移动方向.dir = Quaternion.Euler(0, rotY, 0) * dir; //移动方向的前方为摄像机前方.（按下W，向摄像机正前方行走）（前进方向必须是摄像机的前方）//m_CC.SimpleMove(dir);m_CC.Move(dir * walkSpeed_Third); //m_CC为CharacterController组件.m_Transform.localRotation = Quaternion.LookRotation(dir);}else{m_Animator.SetBool("Walk", false);}}
/// <summary>/// 第一人称.人物移动操作./// </summary>private void MoveUpdate_FirstController(){//按住左SHIFT 加速.if (Input.GetKey(KeyCode.LeftShift)){isRun = true; //加速.}else{isRun = false; //正常速度.}//按下了 W A S D.if (v != 0 || h != 0){//todo:----->>当前动画默认是移动的.而且没有向后走的动画.所以第一人称不使用动画.float rotY = playerCamera.transform.rotation.eulerAngles.y;//摄像机世界坐标前方.Vector3 dir = new Vector3(h, 0, v); //移动方向.dir = Quaternion.Euler(0, rotY, 0) * dir; //移动方向的前方为摄像机前方.（按下W，向摄像机正前方行走）（前进方向必须是摄像机的前方）if (isRun) //加速.{//m_CC.SimpleMove(dir * runSpeed_First);m_CC.Move(dir * runSpeed_First); //m_CC为CharacterController组件.}else //正常速度.{//m_CC.SimpleMove(dir * walkSpeed_First);m_CC.Move(dir * walkSpeed_First);}}}
/// <summary>/// 漫游模式.人物移动操作.（不受重力影响，飞行.）/// </summary>private void MoveUpdate_GodController(){//按住左SHIFT 加速.if (Input.GetKey(KeyCode.LeftShift)){isRun = true; //加速.}else{isRun = false; //正常速度.}//按下了 W A S D.if (v != 0 || h != 0){float rotY = playerCamera.transform.localRotation.eulerAngles.y; //摄像机自身坐标前方.左右.float rotX = playerCamera.transform.localRotation.eulerAngles.x; //摄像机自身坐标前方.上下.Vector3 dir = new Vector3(h, 0, v); //移动方向.dir = Quaternion.Euler(rotX, rotY, 0) * dir; //移动方向的前方为摄像机前方.（按下W，向摄像机正前方行走）（前进方向必须是摄像机的前方）if (isRun) //加速.{//m_CC.SimpleMove(dir * runSpeed_First);//m_CC.Move(dir * runSpeed_First);m_Transform.Translate(dir * runSpeed_God);}else //正常速度.{//m_CC.SimpleMove(dir * walkSpeed_First);//m_CC.Move(dir * walkSpeed_First);m_Transform.Translate(dir * walkSpeed_God);}}}
视角控制：(放在LateUpdate)
//----->>第三人称视角控制.void Start () {m_Transform = gameObject.GetComponent<Transform>();//playerPerson = GameObject.Find("Player/Person").GetComponent<Transform>();playerPerson = GameObject.Find("Player/Person/HeadPos").GetComponent<Transform>(); //最好朝向的是人物的头部.dir = playerPerson.position - m_Transform.localPosition; //先获取摄像机指向人物的方向向量. //朝向头部时，不能使用playerPerson.localPosition}/// <summary>/// 第三人称 摄像机旋转控制./// </summary>private void CameraController_ThirdController(){float x = Input.GetAxis("Mouse X") * rotateSpeed;float y = Input.GetAxis("Mouse Y") * rotateSpeed;distance -= (Input.GetAxis("Mouse ScrollWheel") * scrollSpeed);distance = Mathf.Clamp(distance, minDis, maxDis);//按住鼠标右键，旋转视角.if (Input.GetMouseButton(1)){Quaternion rotX = Quaternion.Euler(0, x, 0);//Quaternion rotY = Quaternion.Euler(-y, 0, 0);//摄像机世界坐标Z 比人物世界坐标Z 远(Z轴在人物前方)，上下滑动方向改变.if (m_Transform.position.z <= playerPerson.position.z) //摄像机在人物后方.{#region 限制上下角度范围.(不同点：rotY的Euler是-y)Quaternion rotY = Quaternion.Euler(-y, 0, 0);if (m_Transform.localRotation.eulerAngles.x < minAngleX) //当向下角度越界时.{if (y < 0) //达到最下，向上滑动.{dir = rotX * rotY * dir;}else //达到最下，向下滑动. (不再向下滑){dir = rotX * dir;}}else if (m_Transform.localRotation.eulerAngles.x > maxAngleX) //当向上角度越界时.{if (y > 0) //达到最上，向下滑动.{dir = rotX * rotY * dir;}else //达到最上，向上滑动.

//----->>第一人称视角控制.void Start () {m_Transform = gameObject.GetComponent<Transform>();playerPerson = GameObject.Find("Player/Person").GetComponent<Transform>();}void LateUpdate () {float x = Input.GetAxis("Mouse X");float y = -Input.GetAxis("Mouse Y");playerPerson.Rotate(Vector3.up, x, Space.Self);m_Transform.Rotate(Vector3.right, y, Space.Self);m_Transform.localRotation = ClampRotationAroundXAxis(m_Transform.localRotation);}/// <summary>/// 限制四元数的欧拉角X.
