 using UnityEngine;

using System.Collections;

using System.IO;  

public class DownPicture : MonoBehaviour {  

    public GameObject plane;

    WWW www;

    string filePath;

    Texture2D test;

    Texture2D newTexture;

    // Use this for initialization

    void Start () {  

        filePath = Application.dataPath + "/Resources/picture.jpg";  

        if (System.IO.File.Exists(filePath))

        {

            Debug.Log("文件已存在");

            test = (Texture2D)Resources.Load("picture", typeof(Texture2D));

            plane.renderer.material.mainTexture = test;

        }

        else

        {

            Debug.Log("文件开始下载");

            StartCoroutine(GetImage());  

        }  

    }  

    // Update is called once per frame

    void Update ()

    {  

    }  

    IEnumerator GetImage()

    {

        string url = "http://192.168.2.105:8080/Test/picture/1.jpg";  

        www = new WWW(url);

        yield return www;

        newTexture = www.texture;  

        byte[] pngData = newTexture.EncodeToPNG();

        File.WriteAllBytes(filePath, pngData);  

    }  

    void OnGUI()

    {  

        if (www.isDone)

            {

                plane.renderer.material.mainTexture = newTexture;  

            }

    }
