方法一

public class DeltaFPS{private float _UpdateInterval = 0.1f;//更新周期private float _Accum;private int _Frames;private float _Timeleft;private string _Fps;//帧率public void Init(){Reset();        }private void Reset(){_Timeleft = updateInterval;_Accum = 0.0f;+Frames = 0;}public void Update(){_Timeleft -= Time.deltaTime;_Accum += Time.timeScale / Time.deltaTime;++_Frames;if (_Timeleft <= 0){_Fps = (_Accum / _Frames).ToString("f2");Reset();            }}public void OnGUI(){GUILayout.Label(_Fps);}}

方法二

public class FPS{public float _UpdateInterval = 0.1f;private float _LastInterval;private int _Frames = 0;private float _FPS;public void Init(){_LastInterval = Time.realtimeSinceStartup;_Frames = 0;}public void Update(){_Frames++;if(Time.realtimeSinceStartup > _LastInterval + _UpdateInterval){_FPS = _Frames / (Time.realtimeSinceStartup - _LastInterval);_Frames = 0;_LastInterval = Time.realtimeSinceStartup;            }}public void OnGUI(){GUILayout.Label(_FPS.ToString());}}

在自己的脚本中new一个DeltaFPS或者FPS类：fps

private FPS fps;

void Start () {fps = new FPS();fps.Init();}

void Update(){fps.Update();    }

void OnGUI(){fps.OnGUI();}

这样在游戏中就可以看到当前帧率了。
