龙之谷—资源文件讲解（2）—资源结构

韩国3D新游戏的——“龙之谷”的三个资源文件（第一节已经讲过）的结构是一样的。
因此，本节就第三个文件作为讲解的内容。

用“Uedit32.exe”软件，将“Resource02.pak”打开，
00000000h: 45 79 65 64 65 6E 74 69 74 79 47 61 6D 65 73 20 ; EyedentityGames
00000010h: 50 61 63 6B 69 6E 67 20 46 69 6C 65 20 30 2E 31 ; Packing File 0.1
00000020h: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ; …………….
00000030h: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ; …………….
…………………

这是资源文件的开头部分，很明显，这个是一个资源文件的描述部分，
“EyedentityGames Packing File 0.1”（Eyedentity游戏打包文件0.1）。
这是资源文件的通常作风，通描述部分一般是作为文件标识来使用的，
即，用来判断文件的兼容性及版本等信息。
龙之谷的这个资源文件的描述部分，用了$100个字节即256个字节。

接下来，我们要看看这一段。
00000100h: 0B 00 00 00 39 22 00 00 8F 49 18 13 00 00 00 00 ; ….9″..廔……
00000110h: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ; …………….
00000120h: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ; …………….
00000130h: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ; …………….
这一段，是一段资源文件的另一个描述部分，
通常的游戏资源文件的结构是这样子的：
文件标识+附加信息+资源内容+检验信息
其中：
文件标识一般有两个部分，即文件标识=标识长度+标识内容
龙之谷的资源文件，采用了256的固定长度，所以，就没了“标识长度”这一部分。

附加信息：有很多种情况，比较常看的有：
附加信息=文件大小+虚拟文件的数量+索引地址
因此，我们来看看这一行，
00000100h: 0B 00 00 00 39 22 00 00 8F 49 18 13 00 00 00 00 ; ….9″..廔……
0B 00 00 00：很显然，这不是文件大小，所以，这个资源文件没有采用这一作法，
39 22 00 00 ：转换一下等于$2239（数据是按低位先存的形式），
等于10进制的8761，这个应当就是虚拟文件的数量

再看一下
8F 49 18 13：转换一下等于$1318498F，用“搜索(S)”>“转到行/页(G)”>录入”0x1318498F”>”确定”
13184980h: E9 41 62 80 E9 E1 FA D7 C3 7F 00 18 72 0D 08 5C ; 锳b 獒 ?..r..\
13184990h: 72 65 73 6F 75 72 63 65 5C 73 6F 75 6E 64 5C 64 ; resource\sound\d
131849a0h: 6D 76 5C 71 5F 6D 61 6E 61 72 69 64 67 65 5F 64 ; mv\q_manaridge_d
131849b0h: 65 73 74 69 6E 79 67 69 72 6C 5F 30 31 5C 30 36 ; estinygirl_01\06
131849c0h: 5F 71 5F 6D 61 6E 61 72 69 64 67 65 5F 64 65 73 ; _q_manaridge_des
131849d0h: 74 69 6E 79 67 69 72 6C 5F 30 31 5F 64 65 73 74 ; tinygirl_01_dest
131849e0h: 72 6F 79 2E 6F 67 67 00 00 00 00 00 00 00 00 00 ; roy.ogg………
131849f0h: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ; …………….
很显然，这是就是虚拟文件的索引部分，
因此，“8F 49 18 13”是指向虚拟文件的索引地址
第一个文件名出来了，
\resource\sound\dmv\q_manaridge_destinygirl_01\06_q_manaridge_destinygirl_01_destroy.ogg
接下来就是要批量提取这些文件名了。

那么，游戏资源文件的文件索引，一般会遵循什么样的方式呢？
通常是这样子的：
单文件索引=文件名长度+文件名+文件信息
其中：文件信息包括：文件的大小，文件的地址，有时，还包含了文件类型，
有时还会出现文件名为索引号，指向另一个资源文件，这个以后再讲。

先来看看龙之谷的资源文件的虚拟文件的索引段内容

在“\resource\”之前没有双字节或四字节，或单字节的一个长度描述，
所以可以判断，龙之谷的资源文件的索引段，是没有“文件名长度”这一部分的，
为什么呢，那还有另一种情况，就是所有的“单文件索引”的文件名本身就是固定长度的，
那么这个固定长度是多少呢，通常来说是256个字节或127个字节，
让我们来看看：
从0x1318498F至0x13184a8F刚好是256个字节，再看看下一个单文件索引段，

结果很显然，也是一样的，

再随机查找一段，

很显明，我们的猜测是正确的。
那么，龙之谷的资源文件中的虚拟文件的索引部分应为：
单文件索引=文件名+文件信息
