使用视差和Movetoward，将相机移动到正确的方向的问题

Question

我有一台电影摄像头，需要使用新的输入系统跟随播放器左右滑动。在我的CM摄像机上，我附加了以下组件：

• 一个称为摄像机滑动
• 播放器输入组件的脚本，该脚本将其映射到默认地图，称为“ Swipe Map”，在屏幕控制资产中，
• 一个名为屏幕屏幕管理器

屏幕输入管理器代码在下面：

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;

[DefaultExecutionOrder(-1)]

public class ScreenInputManager : MonoBehaviourSingleton<ScreenInputManager>
{
    public GameObject player;

    #region
    public delegate void StartTouch(Vector2 position, float time);
    public event StartTouch OnStartTouch;
    public delegate void EndTouch(Vector2 position, float time);
    public event StartTouch OnEndTouch;
    #endregion

    private ScreenControls screenControls;
    private Camera mainCamera;

    private void Awake()
    {
        screenControls = new ScreenControls(); // new instance of input manager
        screenControls.SwipeMap.Enable();
        screenControls.Enable();
        mainCamera = Camera.main;
    }

    private void OnEnable()
    {
        screenControls.Enable();
    }

    private void OnDisable()
    {
        screenControls.Disable();
    }

    private void Start()
    {
        screenControls.SwipeMap.PrimaryContact.started += context => StartTouchPrimary(context);
        screenControls.SwipeMap.PrimaryContact.canceled += context => EndTouchPrimary(context);
    }

    private void StartTouchPrimary(InputAction.CallbackContext context)
    {
        if (OnStartTouch != null) OnStartTouch(Utils.ScreenToWorld(mainCamera, screenControls.SwipeMap.PrimaryPosition.ReadValue<Vector2>()), (float)context.startTime); // avoid using screen to world here, do it later 
    }

    private void EndTouchPrimary(InputAction.CallbackContext context)
    {
        if (OnEndTouch != null) OnEndTouch(Utils.ScreenToWorld(mainCamera, screenControls.SwipeMap.PrimaryPosition.ReadValue<Vector2>()), (float)context.time); // avoid using screen to world here, do it later 
    }

    public Vector2 PrimaryPosition()
    {
        return screenControls.SwipeMap.PrimaryPosition.ReadValue<Vector2>();
    }
}

摄像机滑动代码如下：

using System.Collections.Generic;
using UnityEngine;
using Cinemachine;

[DefaultExecutionOrder(-1)]

public class CameraSwipe : MonoBehaviour
{
    [SerializeField] private float minimumDistance = 1f;
    [SerializeField] private float maximumTime = 1f;
    [SerializeField, Range(0f, 1f)] private float directionThreshhold = 0.9f;

    // private ScreenInputManager inputSystem;

    private Vector2 startPosition;
    private float startTime;
    private Vector2 endPosition;
    private float endTime;
    private Vector3 targetPosition;

    private ScreenInputManager inputProvider;
    private CinemachineVirtualCamera virtualCamera;
    private Rigidbody2D cameraRigid;
    private Transform cameraTransform;

    private void Awake()
    {
        inputProvider = GetComponent<ScreenInputManager>();
        virtualCamera = GetComponent<CinemachineVirtualCamera>();
        cameraRigid = GetComponent<Rigidbody2D>();
        cameraTransform = virtualCamera.VirtualCameraGameObject.transform;
    }

    private void OnEnable()
    {
        inputProvider.OnStartTouch += SwipeStart;
        inputProvider.OnEndTouch += SwipeEnd;
    }

    private void OnDisable()
    {
        inputProvider.OnStartTouch -= SwipeStart;
        inputProvider.OnEndTouch -= SwipeEnd;
    }

    private void SwipeStart(Vector2 position, float time)
    {
        startPosition = position;
        startTime = time;
    }


    private void SwipeEnd(Vector2 position, float time)
    {
        endPosition = position;
        endTime = time;
    }

    private void Update()
    {
        if (Vector3.Distance(startPosition, endPosition) >= minimumDistance && (endTime - startTime) <= maximumTime)
        {
            Debug.DrawLine(startPosition, endPosition, Color.red, 5f);
            Vector3 direction = endPosition - startPosition; // halfway between start and end?

            targetPosition = cameraTransform.position; 
            targetPosition.x =  -direction.x;
            Vector2 direction2D = new Vector2(direction.x, direction.y).normalized;
            SwipeDirection(targetPosition, direction2D);
        }
    }

    private void SwipeDirection(Vector3 direction, Vector2 direction2D)
    {
        if (Vector2.Dot(Vector2.left, direction) > directionThreshhold)
        {
            
            Debug.Log("left " + " the direction 2d is: " + direction2D);
            cameraTransform.position = Vector3.MoveTowards(cameraTransform.position, direction, Time.deltaTime * (float) 3);

        }

        else if (Vector2.Dot(Vector2.right, direction) > directionThreshhold)
        {
            Debug.Log("right " + " the direction 2d is: " + direction2D);
            cameraTransform.position = Vector3.MoveTowards(cameraTransform.position, direction, Time.deltaTime * (float) 3);
        }
    }
}

问题 - 问题是，当我向右滑动时，它似乎会发现左滑动屏幕。似乎并没有轻易从右铲中挑选。

我尝试过的内容： - 我认为这可能与在update（）中调用SwipDirection有关，而实际上应该在Swipeend（）末尾称呼它。但是当我这样做时，因为它没有不断更新，所以相机只会移动一点，根本就不会流畅。

我还试图做一堆debug.logs。当变量方向2D（在第二个代码块中）等于“ 0”时，似乎会失速。有人可以帮我解决这个问题吗？
