VR触摸盘触摸控制位移

之前接触过别人写的VR移动脚本，但是没有细看里面的内容，只是会用而已，现在换工作了，只能自己写了（菜鸟一个，大神勿喷）

using UnityEngine;
using VRTK;
using VR;

public class VR_CameraMove : MonoBehaviour
{
    public float _moveSpeed;
    public bool isTouchStart = false;
    public Vector2 touchVec;

    private VR_ControllerEvents vr_ControllerEvents;

    private void Awake()
    {
        vr_ControllerEvents = FindObjectOfType<VR_ControllerEvents>();
        if (vr_ControllerEvents.controllerType == ControllerType.Right)
        {
            vr_ControllerEvents.touchPadTouchStart += TouchPadTouchStart;
            vr_ControllerEvents.touchPadAxisChanged += TouchPadAxisChanged;
            vr_ControllerEvents.touchPadTouchEnd += TouchPadTouchEnd;
        }
    }

    private void Start()
    {
        _moveSpeed = PlayerPrefs.GetFloat("VR_CameraMove");
    }

    private void Update()
    {
        if (isTouchStart)
        {
            MoveController(touchVec);
        }
    }

    /// <summary>
    /// 设置移动速度
    /// </summary>
    /// <param name="speed">速度数值</param>
    public void SettingMoveSpeed(float speed)
    {
        _moveSpeed = speed;
    }

    private void MoveController(Vector2 vector)
    {
        Vector3 direction = new Vector3(vector.x, 0, vector.y);
        transform.Translate(direction * _moveSpeed * Time.deltaTime, Space.Self);
    }
    private void TouchPadTouchEnd(object sender, ControllerInteractionEventArgs e)
    {
        isTouchStart = false;
    }
    private void TouchPadAxisChanged(object sender, ControllerInteractionEventArgs e)
    {
        touchVec = e.touchpadAxis;
    }
    private void TouchPadTouchStart(object sender, ControllerInteractionEventArgs e)
    {
        isTouchStart = true;
    }
}
