进阶六：资源文件的补全

虽然资源文件没有库文件那么重要，没有它我们仍然可以启动游戏，但是资源文件中包含语言文件、声音文件等，它可以带来更好的游戏体验。
（顺便说一句，MainForm.cs中要把
public MainForm()
{
InitializeComponent();
try
{
//读取版本
listBox1.Items.Clear();
String[] vers = Directory.GetDirectories(Application.StartupPath + "\\.minecraft\\versions");
foreach (String item0 in vers)
{
listBox1.Items.Add(item0.Replace(Application.StartupPath + "\\.minecraft\\versions\\",""));
}
}
catch (Exception)
{
throw;
}
}
的throw;删掉，变为
public MainForm()
{
InitializeComponent();
try
{
//读取版本
listBox1.Items.Clear();
String[] vers = Directory.GetDirectories(Application.StartupPath + "\\.minecraft\\versions");
foreach (String item0 in vers)
{
listBox1.Items.Add(item0.Replace(Application.StartupPath + "\\.minecraft\\versions\\",""));
}
}
catch (Exception)
{
}
}
）

下面让我来揭示一下资源文件的下载原理。

0.0

请您在回头看一看1.7.2纯净版的json文件（万能的json）。

请看"assetIndex": {}这一段。

"url"告诉我们一个叫legacy.json的下载地址。

totalSize告诉我们资源文件的总大小为153475165字节。

legacy.json下载下来内容如下：

这个json中的objects的每个项都是我们需要下载的。下载地址为reso删urces.dow掉nload.min中ecraft.n文et/hash值的前两位/完整的hash值。

这些文件都是没有扩展名的。

支持，不过vs2010太旧了，现在CSharp已经出6.0了，快上VS2015吧

不过1.7.2特殊。它不但需要下载，还需要按照json数据重复制文件才能行。

json数据中的"virtual": true告诉我们了这些。我们可以模仿HMCL，将它们复制到virtual\legacy文件夹下。
