我正在制作一款无尽的跑步者移动的游戏。PC控制工作完美，左右触摸/滑动控制也工作正常。问题是当我向上滑动跳跃时，游戏者跳跃，但随后也向左或向右移动（看起来是随机的）。就我的一生而言，我都想不通。这是我的第一个C#项目，所以我的代码/游戏是教程和谷歌搜索的弗兰肯斯坦。我发现刚体组件有点太晚了，但我不想现在就开始使用它，如果我没有必要...请帮助，我完全不知所措。我也想提前道歉，如果我的代码是非常混乱和不连贯的，我已经尽力了。以下是我的球员移动脚本：

PC质控品

public class PlayerMove : MonoBehaviour
{
    public float moveSpeed = 8;
    public float leftRightSpeed = 7;
    static public bool canMove = false; 
    public KeyCode moveL;
    public KeyCode moveR;
    public float horizVel = 0;
    public int laneNum = 2;
    public string controlLocked = "n";
    private float speedUpTime;
    private float waitTime = 0.45f;
    private Vector3 startTouchPosition;
    private Vector3 endTouchPosition;
    public GroundCheck groundCheck;
    public float jumpForce=7;
    public float gravity = -9.81f;
    public float gravityScale = 3;
    public float jumpCoolDown = 0.5f;
    private float lastJumpTime = 0;
    float velocity;

    // Start is called before the first frame update
    void Start()
    {
        speedUpTime = Time.time;
    }

    // Update is called once per frame
    void Update()
    {
        if (Time.time - speedUpTime >= 10f)
        {
            moveSpeed += 1;
            leftRightSpeed +=1;
            waitTime -= 0.05f;
            speedUpTime = Time.time;
        }

        transform.position += new Vector3(horizVel, 0, moveSpeed) * Time.deltaTime;

        if((Input.GetKeyDown(moveL)) && (laneNum>1)&& (controlLocked == "n"))
        {
            horizVel = -leftRightSpeed;
            StartCoroutine(stopSlide());
            laneNum -= 1;
            controlLocked = "y";
        }

        if((Input.GetKeyDown(moveR)) && (laneNum<3)&& (controlLocked == "n"))
        {
            horizVel = leftRightSpeed;
            StartCoroutine(stopSlide());
            laneNum += 1;
            controlLocked = "y";
        }
        
        velocity += gravity * gravityScale * Time.deltaTime;
        if (groundCheck.isGrounded && velocity < 0)
        {
            velocity = 0;
            lastJumpTime = 0;
        }
        if (Input.GetKeyDown(KeyCode.Space) && (Time.time - lastJumpTime) > jumpCoolDown)
        {
            lastJumpTime = Time.time;
            velocity = jumpForce;
        }
        transform.Translate(new Vector3(0, velocity, 0) * Time.deltaTime);

触摸控制

if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
        {
            startTouchPosition = Input.GetTouch(0).position;
        }
        
        if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Ended)
        {
            endTouchPosition = Input.GetTouch(0).position;
            // Check for horizontal swipe
            if((endTouchPosition.x < startTouchPosition.x) && (laneNum>1)&& (controlLocked == "n"))
            {
                horizVel = -leftRightSpeed;
                StartCoroutine(stopSlide());
                laneNum -= 1;
                controlLocked = "y";
            }

            if((endTouchPosition.x > startTouchPosition.x) && (laneNum < 3) && (controlLocked == "n"))
            {
                horizVel = leftRightSpeed;
                StartCoroutine(stopSlide());
                laneNum += 1;
                controlLocked = "y";
            }
        
            // Check for vertical swipe
            if ((endTouchPosition.y > startTouchPosition.y) && (Time.time - lastJumpTime) > jumpCoolDown)
            {
                lastJumpTime = Time.time;
                velocity = jumpForce;
            }
        }
    }

     IEnumerator stopSlide()
    {
        yield return new WaitForSeconds(waitTime);
        horizVel = 0;
        controlLocked = "n";
    }
}

我已经玩了好几个小时了，我甚至不记得我试过什么。要么玩家停止移动，要么右变成左，要么跳是右，要么左是跳，等等......
