[csharp] view plaincopy
 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;  
  
            }  
    }  
}
