HTC vive手柄各个按钮的响应事件，已实现的功能是按手柄上的原盘上下左右键移动，是平移，不是射线瞬移。这种方式在眼镜里太晕了。

using UnityEngine;
    using System.Collections;
    
    public class Move : MonoBehaviour {
    
        /// <summary>  
        /// 手柄位置  
        /// </summary>  
        SteamVR_TrackedObject tracked;
    
    
        /// <summary>  
        /// 玩家  
        /// </summary>  
        public Transform player;
    
        /// <summary>  
        /// 方向   
        /// </summary>  
        public Transform dic;
    
        /// <summary>  
        /// 速度  
        /// </summary>  
        public float speed;
