如何在统一移动ThirdPersonController时解决口吃问题？

Question

当我移动我的角色周围的场景是口吃。只有当我移动角色时。如果角色站不动，那就没事了。一旦我使用按键W S D A就会出现口吃。

我在一个答案中读到有人问过，相机处理部件应该在LateUpdate功能中。我在这个脚本中有一个LateUpdate函数，所以我不确定问题出在哪里。

2013年的答案是“将你的相机处理代码放在LateUpdate中。这样你就可以在Update方法中移动你的玩家对象，相机会在LateUpdate方法中追踪他。当我有相机时我遇到同样的问题按照代码和字符移动代码进行更新。“

在spector的主摄像头中，我在c＃中使用了这个CameraScript：

using UnityEngine;
using System.Collections;

public class CameraScript : MonoBehaviour {


    public Transform TargetLookAt;

    public float Distance = 5.0f;
    public float DistanceMin = 3.0f;
    public float DistanceMax = 10.0f;

    private float mouseX = 0.0f;
    private float mouseY = 0.0f;
    private float startingDistance = 0.0f;    
    private float desiredDistance = 0.0f;

    public float X_MouseSensitivity = 5.0f;
    public float Y_MouseSensitivity = 5.0f;
    public float MouseWheelSensitivity = 5.0f;
    public float Y_MinLimit = -40.0f;
    public float Y_MaxLimit = 80.0f;

    public float DistanceSmooth = 0.05f;    
    private float velocityDistance = 0.0f;    
    private Vector3 desiredPosition = Vector3.zero;

    public float X_Smooth = 0.05f;
    public float Y_Smooth = 0.1f;
    private float velX = 0.0f;
    private float velY = 0.0f;
    private float velZ = 0.0f;
    private Vector3 position = Vector3.zero;

    CursorLockMode wantedMode;    


    void  Start (){
        Distance = Mathf.Clamp(Distance, DistanceMin, DistanceMax);
        startingDistance = Distance;
        Reset();
        SetCursorState();
        OnGUI();

    }

    void  LateUpdate (){
        if (TargetLookAt == null)
            return;

        HandlePlayerInput();

        CalculateDesiredPosition();

        UpdatePosition();
    }

    void  HandlePlayerInput (){
        float deadZone= 0.01f; // mousewheel deadZone

        //if (Input.GetMouseButton(1))
        //{
        mouseX += Input.GetAxis("Mouse X") * X_MouseSensitivity;
        mouseY -= Input.GetAxis("Mouse Y") * Y_MouseSensitivity;
        //}

        // this is where the mouseY is limited - Helper script
        mouseY = ClampAngle(mouseY, Y_MinLimit, Y_MaxLimit);

        // get Mouse Wheel Input
        if (Input.GetAxis("Mouse ScrollWheel") < -deadZone || Input.GetAxis("Mouse ScrollWheel") > deadZone)
        {
            desiredDistance = Mathf.Clamp(Distance - (Input.GetAxis("Mouse ScrollWheel") * MouseWheelSensitivity), 
                DistanceMin, DistanceMax);
        }
    }

    void  CalculateDesiredPosition (){
        // Evaluate distance
        Distance = Mathf.SmoothDamp(Distance, desiredDistance, ref velocityDistance, DistanceSmooth);

        // Calculate desired position -> Note : mouse inputs reversed to align to WorldSpace Axis
        desiredPosition = CalculatePosition(mouseY, mouseX, Distance);
    }

    Vector3  CalculatePosition ( float rotationX ,   float rotationY ,   float distance  ){
        Vector3 direction = new Vector3(0, 0, -distance);
        Quaternion rotation = Quaternion.Euler(rotationX, rotationY, 0);
        return TargetLookAt.position + (rotation * direction);
    }

    void  UpdatePosition (){
        float posX= Mathf.SmoothDamp(position.x, desiredPosition.x, ref velX, X_Smooth);
        float posY= Mathf.SmoothDamp(position.y, desiredPosition.y, ref velY, Y_Smooth);
        float posZ= Mathf.SmoothDamp(position.z, desiredPosition.z, ref velZ, X_Smooth);
        position = new Vector3(posX, posY, posZ);

        transform.position = position;

        transform.LookAt(TargetLookAt);
    }

    void  Reset (){
        mouseX = 0;
        mouseY = 10;
        Distance = startingDistance;
        desiredDistance = Distance;
    }

    float ClampAngle ( float angle ,   float min ,   float max  ){
        while (angle < -360 || angle > 360)
        {
            if (angle < -360)
                angle += 360;
            if (angle > 360)
                angle -= 360;
        }

        return Mathf.Clamp(angle, min, max);
    }

    // Apply requested cursor state
    void SetCursorState ()
    {
        Cursor.lockState = wantedMode;
        // Hide cursor when locking
        Cursor.visible = (CursorLockMode.Locked != wantedMode);
    }

    void OnGUI ()
    {
        GUILayout.BeginVertical ();
        // Release cursor on escape keypress
        if (Input.GetKeyDown (KeyCode.Escape))
            Cursor.lockState = wantedMode = CursorLockMode.None;

        switch (Cursor.lockState) {

            break;
        case CursorLockMode.Confined:
