unity 创建第一个JavaScript 脚本，附加物体之上 利用键盘 对物体进行移动 以及帧率显示

#pragma strict

var speed : float = 100;
var m_LastUpdateShowTime : float =  0f; //上一次更新帧率的时间;
var m_UpdateShowDeltaTime : float =0.01f;//更新帧率的时间间隔;
var m_FrameUpdate : int = 0;//帧数
var m_FPS : float = 0;
function Awake ()
{
	Application.targetFrameRate = 100;
}

function Start () {

     m_LastUpdateShowTime=Time.realtimeSinceStartup;
}

function Update () {

	var x:float = Input.GetAxis("Horizontal") * Time.deltaTime * speed;
	var z:float = Input.GetAxis("Vertical") *Time.deltaTime * speed;
	transform.Translate(x,0,z);

	m_FrameUpdate++;
        if(Time.realtimeSinceStartup-m_LastUpdateShowTime>=m_UpdateShowDeltaTime)
        {
            m_FPS=m_FrameUpdate/(Time.realtimeSinceStartup-m_LastUpdateShowTime);
            m_FrameUpdate=0;
            m_LastUpdateShowTime=Time.realtimeSinceStartup;
        }  

}

 function OnGUI() {
        GUI.Label(new Rect(Screen.width/2,0,200,100),"FPS: "+m_FPS);
    }
