如何在Unity中显示当前游戏运行帧数?

1.首先在工程中新建一个js脚本，双击该脚本进行编辑，代码如下

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;
}
}

2.写好后加入到GUItext即可
