Unity3D获取FPS帧率代码 测试帧率
JavaScript - FramesPerSecond.js// Attach this to a GUIText to make a frames/second indicator.
//
// It calculates frames/second over each updateInterval,
// so the display does not keep changing wildly.
//
// It is also fairly accurate at very low FPS counts (<10).
// We do this not by simply counting frames per interval, but
// by accumulating FPS for each frame. This way we end up with
// correct overall FPS even if the interval renders something like
// 5.5 frames.
var updateInterval = 0.5;
private var accum = 0.0; // FPS accumulated over the interval
private var frames = 0; // Frames drawn over the interval
private var timeleft : float; // Left time for current interval
function Start()
{
if( !guiText )

print ("FramesPerSecond needs a GUIText component!");

// Interval ended - update GUI text and start new interval

// display two fractional digits (f2 format)
guiText.text = "" + (accum/frames).ToString("f2");

CSharp HUDFPS.cs
A C# implementation of the above converted by Opless. The main difference is the colour change when FPS dips too low.

frames = 0 就是不知道怎么使用 好东西 学习 学习 很不错 顶顶多好 真心顶 说的非常好 LZ真是人才 楼主是超人 顶顶多好
