将场景导出XML或JSON或二进制而且解析还原场景

导出unity场景的全部游戏对象信息，一种是XML一种是JSON。

本篇文章我们把游戏场景中游戏对象的、旋转、缩放、平移与Prefab的名称导出在XML与JSON中。然后解析刚刚导出的XML或JSON通过脚本把导出的游戏场景还原。在Unity官网上下载随便下载一个demo Project。例如以下图所看到的这是我刚刚在官网上下载的一个范例程序。

接着将层次视图中的全部游戏对象都封装成Prefab保存在资源路径中，这里注意一下假设你的Prefab绑定的脚本中有public Object 的话 ，须要在代码中改一下。。用 Find() FindTag()这类方法在脚本中Awake()方法中来拿，不然Prefab动态载入的时候无法赋值的，例如以下图所看到的，我把封装的Prefab对象都放在了Resources/Prefab目录下。
OK，如今我们就须要编写我们的导出工具、在Project视图中创建Editor目录，接着创建脚本MyEditor 。例如以下图所看到的。

由于编辑的游戏场景数量比較多，导出的时候我们须要遍历全部的游戏场景，一个一个的读取场景信息。然后取得游戏场景中全部游戏对象的Prefab的 名称 旋转 缩放 平移。

有关XML的使用请大家看我的上一篇文章： Unity3d研究院之使用 C#合成解析XML与JSON（四十一） 代码中我仅仅凝视重点的部分。嘿嘿。

OK。此时我们就能够导出游戏场景的信息拉，注意游戏场景的须要如今Project Setting 中注冊。

点击 GameObject – > Export    XML 和 GameObject – > ExportJson 菜单项就可以開始生成。

例如以下图所看到的，场景导出完成后。会将xml 与Json 文件保存在StreamingAssets路径下。放在这里的原因是方便移动平台移植，由于它们属于二进制文件，移动平台在读取二进制文件的路径是不一样的。一定要放在这里喔。
接着。我继续创建两个游戏场景，一个用来解析XML的场景，一个用来解析JSON的场景。

 
XML场景中，创建一个空的游戏对象，把XML.cs挂上去。

雨松MOMO 祝大家学习愉快，准备睡觉。安 。欢迎讨论与学习 嘿嘿。
补充
近期在做client与server的交互。使用JSON 和XML会感觉数据量太大。影响效率。最后使用二进制的方式来完毕。例如以下图所看到的。使用二进制能够把空间节省到803K 。是不是非常不错呢？ 以下我们開始学习怎样制作吧。



导出场景时添加导出二进制文件选项，代码例如以下。

                                    if (obj.transform.parent == null)
                                    {
//注解 直接写入字符串
                                                bw.Write(name);
                                                bw.Write(obj.name);
  
                                                short posx = (short)(obj.transform.position.x * 100);


注解
在写入二进制数据时用到的核心类就是BinaryWriter 。Binary是二进制的意思 ，可见操作二进制写入就用BinaryWriter了。 经常使用的数据类型会分配固定的字节数量，如果BinaryWriter 写入一个short 那么就占2字节，写一个 int 就占4字节，如果是数组的话须要数组类型字节长度在乘以数组长度。
byte：一个字节（8位） 
short：两个字节（16位） 
int：四个字节（32位）(一个字长) 
long：八个字节（64位）
float：四个字节（32位）
double：八个字节（64位）然后在说说string。字符串它并非标准的数据类型，它是一个对象 object 那么它的字节长度就是可变的。開始我也在string 上纠结了一小会儿。还有BinaryWriter 在写入string 的时候会现将字符串的长度以byte的形式储存。然后在储存字符串的字节长度。那么在解析字符串的时候须要先解析字符串长度。然后在依据长度取得后面相应长度的字节数组，再把这个字节数组转换成string即可啦。

还有，上面我用的是short x 100 事实上上为了节省长度， 由于short是2字节。float是4字节。

我在解析的时候用short 在除以100 就能够 换算成float拉。
然后我们在看看解析的代码。写入的时候我们用的是BinaryWriter 那么读取的时候应该是 BinaryReader。 Binary.cs

执行一下，场景依旧生成的很完美，在处理二进制解析的时候须要特别注意的就是字节对齐，由于你的全部数据事实上就是一个byte[]字节数组，须要有理有序的把字节数组拆分，然后在转换成相应的数据，所以一定要对齐不然肯定会出错的。
最后把代码放出来，晚安 Good Ngith 哇咔咔。

留言中刚好有人讨论到这块。

另外另一种方式也能够实现动态添加建立场景，使用.unity 来实现场景的载入，我认为这样的方式可能会更好一些。我在网上已经发现有人写了。那就转载过来吧。


在unity中，场景（scene）多半通过在build settings中点击add current或者把场景拖进面板实现，假如不这么做。你的场景便不会被载入，哪怕你制定了绝对路径。
就是说。一个游戏里要载入多少场景多半都是固定的。


这个方案会有非常多不便。不easy动态载入场景。所以我们今天要说的，是一种动态载入场景的方法。
首先。你须要一个编辑器文件。放在editor目录下。注意。这个文件不能够继承自monobehaviour

public class BuildSceneEditor{
    [@MenuItem("build/BuildWebplayerStreamed")] 
    static void Build(){
        string[] levels = new string[]{"Assets/Level1.unity","Assets/Level2.unity"}; 
        BuildPipeline.BuildStreamedSceneAssetBundle(levels,"streamed.unity3d",BuildTarget.WebPlayer); 
    }
}
这样，在你的unity编辑器上出现了一个button。你运行这个button，则会在你的Assets同级文件夹下出现你build好的streamed.unity3d文件。你把这个文件放在server上。以下一步就是下载这个文件并build了。

WWW download = WWW.LoadFromCacheOrDownload("http://xxx/streamed.unity3d",0); 
yield return download; 
Application.LoadLevel("Level1");
大家注意到了吗。下载好以后就能够直接loadlevel了。不须要手动进行add current的操作了。


最后我在补充一下使用.unity3d确实方便非常多，由于它不仅会把场景打包进去，而且还会把场景中相应的资源文件打包进去。举个样例，你将美工做好的模型文件放在Project视图中，然后在将模型放在Hierarchy视图中的 100,100,100坐标点中，最后把该场景打包成.unity3d文件。

此时你在新建一个project仅仅需下载刚刚打包的场景文件，他会自己主动把模型放在 100，100，100坐标点中。
这说明场景文件，包括了该场景中所用到的全部模型，而且还包括了模型资源与Hierarchy视图的关系。它会带来一个弊端。比方你有N个场景。每一个场景中都有同样的模型文件，这样每一个场景都须要反复下载这些同样的模型文件，所以我认为不妨使用assetbundle来对同类的资源文件进行分包处理。
