Unity实现手机摇一摇震动

using UnityEngine;using System.Collections; public class FunctionVibrate : MonoBehaviour{ //实现手机晃动震动效果 // Use this for initialization float old_y = 0; float new_y; float max_y = 0; float min_y = 0; float d_y = 0; public float distance = 0.3f; void Start () {  }  // Update is called once per frame void Update () {  new_y = Input.acceleration.y; d_y = new_y - old_y; old_y = new_y; if(Input.GetKey(KeyCode.Escape)) {  Application.Quit(); } } int i; void OnGUI()  { //if(GUI.Button(new Rect(0,100,100,32),"vibrate!")) //{ // //震动 // Handheld.Vibrate(); //} GUI.Label(new Rect(100,100,100,100),"g:"+Input.acceleration+"d_y:"+d_y); GUI.Label(new Rect(100,200,100,100),"i:"+i); if(d_y>distance) {  i++;  Handheld.Vibrate(); } }}
