OK。此时我们就可以导出游戏场景的信息拉，注意游戏场景的需要现在Project Setting 中注册。点击 GameObject – > Export XML 和 GameObject – > ExportJson 菜单项即可开始生成。
如下图所示，场景导出完毕后，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，因为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。
publicclassXML : MonoBehaviour {
// Use this for initialization
voidStart ()
//电脑和iphong上的路径是不一样的，这里用标签判断一下。
#if UNITY_EDITOR
stringfilepath = Application.dataPath +"/StreamingAssets"+"/my.xml";
#elif UNITY_IPHONE
stringfilepath = Application.dataPath +"/Raw"+"/my.xml";
#endif
//如果文件存在话开始解析。
if(File.Exists (filepath))
XmlDocument xmlDoc = newXmlDocument();
xmlDoc.Load(filepath);
XmlNodeList nodeList=xmlDoc.SelectSingleNode("gameObjects").ChildNodes;
foreach(XmlElement sceneinnodeList)
//因为我的XML是把所有游戏对象全部导出， 所以这里判断一下只解析需要的场景中的游戏对象
//JSON和它的原理类似
if(!scene.GetAttribute("name").Equals("Assets/StarTrooper.unity"))
continue;
foreach(XmlElement gameObjects inscene.ChildNodes)
stringasset = "Prefab/"+ gameObjects.GetAttribute("name");
Vector3 pos = Vector3.zero;
Vector3 rot = Vector3.zero;
Vector3 sca = Vector3.zero;
foreach(XmlElement transform ingameObjects.ChildNodes)
foreach(XmlElement prs intransform.ChildNodes)
{
if(prs.Name == "position")
{
foreach(XmlElement position inprs.ChildNodes)
switch(position.Name)
{
case"x":
pos.x = float.Parse(position.InnerText);
break;
case"y":
pos.y = float.Parse(position.InnerText);
case"z":
pos.z = float.Parse(position.InnerText);
}
}elseif(prs.Name == "rotation")
foreach(XmlElement rotation inprs.ChildNodes)
switch(rotation.Name)
case"x":
rot.x = float.Parse(rotation.InnerText);
break;
case"y":
rot.y = float.Parse(rotation.InnerText);
case"z":
rot.z = float.Parse(rotation.InnerText);
}elseif(prs.Name == "scale")
foreach(XmlElement scale inprs.ChildNodes)
switch(scale.Name)
sca.x = float.Parse(scale.InnerText);
sca.y = float.Parse(scale.InnerText);
sca.z = float.Parse(scale.InnerText);
}
//拿到 旋转 缩放 平移 以后克隆新游戏对象
GameObject ob = (GameObject)Instantiate(Resources.Load(asset),pos,Quaternion.Euler(rot));
ob.transform.localScale = sca;
// Update is called once per frame
voidUpdate ()
voidOnGUI()
if(GUI.Button(newRect(0,200,200),"XML WORLD"))
Application.LoadLevel("JSONScene");
接着JSON场景中，创建一个空的游戏对象，把JSON.cs挂上去。
02 03 04 05 06 publicclassJSON : MonoBehaviour {
07 08 09 10 11 12 stringfilepath = Application.dataPath +"/StreamingAssets"+"/json.txt";
13 14 stringfilepath = Application.dataPath +"/Raw"+"/json.txt";
15 #endif
16 17 StreamReader sr= File.OpenText(filepath);
18 stringstrLine = sr.ReadToEnd();
19 JsonData jd = JsonMapper.ToObject(strLine);
20 JsonData gameObjectArray = jd["GameObjects"];
21 inti,j,k;
22 for(i = 0; i < gameObjectArray.Count; i++)
23 24 JsonData senseArray = gameObjectArray["scenes"];
25 for(j = 0; j < senseArray.Count; j++)
26 {
27 stringsceneName = (string)senseArray[j]["name"];
28 if(!sceneName.Equals("Assets/StarTrooper.unity"))
29 30 31 32 JsonData gameObjects = senseArray[j]["gameObject"];
33 34 for(k = 0; k < gameObjects.Count; k++)
35 36 stringobjectName = (string)gameObjects[k]["name"];
37 stringasset = "Prefab/"+ objectName;
38 39 40 41 42 JsonData position = gameObjects[k]["position"];
43 JsonData rotation = gameObjects[k]["rotation"];
44 JsonData scale = gameObjects[k]["scale"];
45 46 pos.x = float.Parse((string)position[0]["x"]);
47 pos.y = float.Parse((string)position[0]["y"]);
48 pos.z = float.Parse((string)position[0]["z"]);
49 50 rot.x = float.Parse((string)rotation[0]["x"]);
51 rot.y = float.Parse((string)rotation[0]["y"]);
52 rot.z = float.Parse((string)rotation[0]["z"]);
53 54 sca.x = float.Parse((string)scale[0]["x"]);
55 sca.y = float.Parse((string)scale[0]["y"]);
56 sca.z = float.Parse((string)scale[0]["z"]);
57 58 59 60 61 62 63 }
64 65 66 67 68 69 voidUpdate () {
70 71 72 73 74 75
76 77 Application.LoadLevel("XMLScene");
