Unity3D中显示运行帧数的代码

//创建一个js脚本，然后写好后加入到GUItext即可

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!");
enabled = false;
return;
}
timeleft = updateInterval;
}

function Update()
{
timeleft -= Time.deltaTime;
accum += Time.timeScale/Time.deltaTime;
++frames;

// Interval ended - update GUI text and start new interval
if( timeleft <= 0.0 )
{
// display two fractional digits (f2 format)
guiText.text = "" + (accum/frames).ToString("f2");
timeleft = updateInterval;
accum = 0.0;
frames = 0;
}
