奔跑的小兔

很常用的代码，论坛里有很多个版本了！

using UnityEngine;

using System.Collections;

public class HHHHHHHH : MonoBehaviour {

public GUIStyle progressbar_bj;   //背景图



public GUIStyle progressbar_qj;   //前景图



public GameObject obj;



WWW www;



bool loading=true;







public Texture img;



float Length=0;







void Start () {



   StartCoroutine(ABC("http://images.earthcam.com/ec_metros/ourcams/fridays.jpg"));



}
// Update is called once per frame



void Update ()



{



   if(!www.isDone)



   {



   print(www.progress);



   loading=true;



   }



   else



   {



   loading=false;



   obj.renderer.material.mainTexture = www.texture;



   www=null;



   }



}




void OnGUI ()



{



//~ GUI.Skin=big;



   if(loading)



   {







   GUI.Label(new Rect(100,30,200,30),"", progressbar_bj);



    GUI.Label(new Rect(100,30,www.progress*200,30),"", progressbar_qj);



   GUI.Label (new Rect (150,35, 200, 30),"Loading:    "+(www.progress*100).ToString().Substring(0,2)+"%");



   }



}







public IEnumerator ABC(string URL)



{



www = new WWW (URL);



yield return www;



}



}
