在Unity3D引擎中，场景资源文件(.unity)是以2进制格式存储的。但同一时候它也有一种基于文本的表现格式。
可在Edit>Project Setting>Editor 中设置：
1.使用binary2text.exe(win下文件夹：EditorDataTools)可将.unity文件转换成.txt文件，仅仅需将.unity文件拖拽到binary2text.exe上就可以生成.txt。
2.Bin2Text.unity为測试场景场景中仅仅有一个名为“sakyaer”的空物体；
3.相应这样一个场景。它的文本格式使用YAML格式存储，信息表例如以下：
- 当中ClassID是Unity3D中类的序列编号。如：GameObject类ClassID=1，具体类的ID參照官方站点http://docs.unity3d.com/Manual/ClassIDReference.html
- ID项为随记分配给每个实例的唯一标识
- 资源文件使用m_作为前缀
- 当中m_GameObject (file 0 path 1163297905)表现transform对gameobject的从属关系

4.Unity3D中对于每个资源文件都会生成相应.meta文件，该文件能够用记事本直接打开；guid（全局唯一标识符，Globally Unique Identifier）是系统随机生成的对资源的标识符，guid在游戏执行时会被用来生成一个hashid。而依据guid的前两位0a能够在projectLibrary文件夹下metadate（元数据）0a文件夹下找到。相应的二进制文件，该文件能够使用binary2text.exe打开，得到的txt文件。记录了.meta文件相应资源的全部具体信息。
