WWW类主要用于从网上下载资源，或从本地引用资源，本篇文章我们就来看看如何封装WWW类，
直接上代码：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class WWWTest ｛
/// <summary>
/// 下载路径
/// </summary>
private string url;
public string URL
｛
set
｛
url = value;
｝
get
｛
return url;
｝
｝
/// <summary>
/// 开始下载
/// </summary>
public virtual void BeginDownLoad()
｛
｝
/// <summary>
/// 下载结束
/// </summary>
public virtual void FinishDownLoad(WWW tepWWW)
｛
｝
/// <summary>
/// 下载出错
/// </summary>
public virtual void ErrorDownLoad()
｛
｝
/// <summary>
/// 下载协程
/// </summary>
/// <returns></returns>
public IEnumerator DownLoad()
｛
BeginDownLoad();
WWW www = new WWW(URL);
yield return www;
if (string.IsNullOrEmpty(www.error))
｛
//下载成功
FinishDownLoad(www);
｝
else
｛
//下载失败
ErrorDownLoad();
｝
｝
｝
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class WWWDownLoad : WWWTest ｛
/// <summary>
/// 构造方法
/// </summary>
/// <param name="url"></param>
public WWWDownLoad(string url)
｛
Init(url);
｝
/// <summary>
/// 丰富URL
/// </summary>
/// <param name="url"></param>
public void Init(string url)
｛
if (Application.platform == RuntimePlatform.Android)
｛
this.URL = "jar:file://" + url;
｝
else if (Application.platform == RuntimePlatform.WindowsEditor || Application.platform == RuntimePlatform.WindowsPlayer)
｛
this.URL = "file:///" + url;
｝
else
｛
this.URL = "file://" + url;
｝
｝
public override void FinishDownLoad(WWW tepWWW)
｛
Debug.Log(tepWWW.text);
｝
｝
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DownLoading : MonoBehaviour ｛
public static DownLoading Instance;
/// <summary>
/// 下载队列
/// </summary>
Queue<WWWTest> DownLoadQueue;
/// <summary>
/// 是否下载完成
/// </summary>
private bool IsFinish;
private void Awake()
｛
Instance = this;
｝
void Start () ｛
DownLoadQueue = new Queue<WWWTest>();
IsFinish = true;
｝
/// <summary>
/// 添加下载任务到下载队列中
/// </summary>
public void AddDownLoad(WWWTest test)
｛
DownLoadQueue.Enqueue(test);
//如果下载完成 开启下载协程
if (IsFinish)
｛
IsFinish = false;
StartCoroutine(DownLoad());
｝
｝
public IEnumerator DownLoad()
｛
while(DownLoadQueue.Count > 0)
｛
WWWTest test = DownLoadQueue.Dequeue();
yield return test.DownLoad();
｝
IsFinish = true;
｝
void Update () ｛
//调用
if (Input.GetKeyDown(KeyCode.A))
｛
string url = Application.dataPath + "/WWW/WWWTest.cs";
WWWDownLoad download1 = new WWWDownLoad(url);
AddDownLoad(download1);
Debug.Log(123);
｝
｝
｝
