下一篇文章试试用线程下载

代码如下

using System.IO;
using UnityEngine;
using System.Net;
using System.Collections;
 
public class Test : MonoBehaviour {
 
  private string[] _urls=new string[10];
  private string [] _localPath = new string[10];
 
 // Use this for initialization
 void Start () 
  {
    for (int i = 0; i < _urls.Length; i++)
    {
      //所有图片的下载地址
      _urls[i] = "http://192.168.1.41:8080/Test/picture/" + (i + 1).ToString() + ".jpg";
      //所有图片的保存路径
      _localPath[i] = Application.dataPath + "/Resources/" + (i + 1).ToString() + ".jpg";
      
    }
 }
 
  // Update is called once per frame
  void Update() 
  {
 
 }
 
  void OnGUI()
  {
    if (GUI.Button(new Rect(0, 0, 100, 30), "下载所有图片"))
    {
      DownLoad();
    }
    //判断文件是否已下载
    for (int i = 0; i < _urls.Length; i++)
    {
      if (File.Exists(_localPath[i]))
      {
        GUI.Button(new Rect(0, 30 * i+30, 50, 30), (i + 1).ToString());
      }
    }
 
    
  }
 
  //下载所有图片
  private void DownLoad()
  {
    for (int i = 0; i < _urls.Length; i++)
    {
      DownLoadAllImages(_urls[i], _localPath[i]);
    }
  }
 
 
  void DownLoadAllImages(string url, string localPath)
  {
    WebClient web = new WebClient();
    web.DownloadFile(url, localPath);
    //以下代码下载完成后执行
  }
}
