Unity一HTC 手柄控制主角行走

实现：头盔转动控制移动的方向，手柄中touchPad的上、下、左、右控制移动的向前、向左、向右、向后移动

 设置头部
 using UnityEngine;
 using System.Collections;

 public class ChildTransform : MonoBehaviour
 {

     public Transform same;

     // Use this for initialization
     void Start () {

     }

     // Update is called once per frame
     void FixedUpdate () {

         transform.localEulerAngles = new Vector3(0,same.localEulerAngles.y,0);

         transform.localPosition = new Vector3(same.localPosition.x, 0, same.localPosition.z);
     }
 }
