unity3D技术之导出Unity场景的所有游戏对象信息.docx

导出Unity场景的所有游戏对象信息，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，如下图所示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所有游戏对象都封装成Prefab保存在资源路径中，这里注意一下如果你的Prefab绑定的脚本中有public Object 的话 ，需要在代码中改一下。用 Find() FindTag()这类方法在脚本中Awake()方法中来拿，不然Prefab动态加载的时候无法赋值的，如下图所示，我把封装的Prefab对象都放在了Resources/Prefab文件夹下。 OK，现在我们就需要编写我们的导出工具、在Project视图中创建Editor文件夹，接着创建脚本MyEditor 。如下图所示。 因为编辑的游戏场景数量比较多，导出的时候我们需要遍历所有的游戏场景，一个一个的读取场景信息。然后取得游戏场景中所有游戏对象的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）代码中我只注释重点的部分，嘿嘿。MyEditor.csC#123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116117118119120121122123124125126127128129130131132133134135136137138139140141142143144145146147148149150151152153154155156157158159160161162163164165166167168169170171172173174175176177178179180181182183184185186187188189190using UnityEngine;using System.Collections;using UnityEditor;using System.Collections.Generic;using System.Xml;using System.IO;using System.Text;using LitJson;public class MyEditor : Editor/将所有游戏场景导出为XML格式MenuItem (GameObject/ExportXML)static void ExportXML ()string filepath = Application.dataPath + /StreamingAssets/my.xml;if(!File.Exists (filepath)File.Delete(filepath);XmlDocument xmlDoc = new XmlDocument();XmlElement root = xmlDoc.CreateElement(gameObjects);/遍历所有的游戏场景foreach (UnityEditor.EditorBuildSettingsScene S in UnityEditor.EditorBuildSettings.scenes) /当关卡启用if (S.enabled) /得到关卡的名称string name = S.path;/打开这个关卡EditorApplication.OpenScene(name);XmlElement scenes = xmlDoc.CreateElement(scenes);scenes.SetAttribute(name,name);foreach (GameObject obj in Object.FindObjectsOfType(typeof(GameObject) if (obj.transform.parent = null) XmlElement gameObject = xmlDoc.CreateElement(gameObjects);gameObject.SetAttribute(name,);gameObject.SetAttribute(asset, + .prefab);XmlElement transform = xmlDoc.CreateElement(transform);XmlElement position = xmlDoc.CreateElement(position);XmlElement position_x = xmlDoc.CreateElement(x);position_x.InnerText = obj.transform.position.x+;

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。C#123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116117118119120121122using UnityEngine;using System.Collections;using System.Xml;using System.IO;public class XML : MonoBehaviour / Use this for initializationvoid Start ()/电脑和iphong上的路径是不一样的，这里用标签判断一下。#if UNITY_EDITORstring filepath = Application.dataPath +/StreamingAssets+/my.xml;#elif UNITY_IPHONEstring filepath = Application.dataPath +/Raw+/my.xml;#endif/如果文件存在话开始解析。if(File.Exists (filepath)XmlDocument xmlDoc = new XmlDocument();xmlDoc.Load(filepath);XmlNodeList nodeList=xmlDoc.SelectSingleNode(gameObjects).ChildNodes;foreach(XmlElement scenein nodeList)/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 in scene.ChildNodes)string asset = Prefab/ + gameObjects.GetAttribute(name);Vector3 pos = Vector3.zero;Vector3 rot = Vector3.zero;Vector3 sca = Vector3.zero;foreach(XmlElement transform in gameObjects.ChildNodes)foreach(XmlElement prs in transform.ChildNodes)if(prs.Name = position)foreach(XmlElement position in prs.ChildNodes)switch(position.Name)case x:pos.x = float.Parse(position.InnerText);break;case y:pos.y = float.Parse(position.InnerText);break;case z:pos.z = float.Parse(position.InnerText);break;else if(prs.Name = rotation)foreach(XmlElement rotation in prs.ChildNodes)switch(rotation.Name)case x:rot.x = float.Parse(rotation.InnerText);break;case y:rot.y = float.Parse(rotation.InnerText);break;case z:rot.z = float.Parse(rotation.InnerText);break;else if(prs.Name = scale)foreach(XmlElement scale in prs.ChildNodes)switch(scale.Name)case x:sca.x = float.Parse(scale.InnerText);break;case y:sca.y = float.Parse(scale.InnerText);break;case z:sca.z = float.Parse(scale.InnerText);break;/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 framevoid Update ()void OnGUI()if(GUI.Button(new Rect(0,0,200,200),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。C#12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364656667686970717273747576777879808182using UnityEngine;using System.Collections;using System.IO;using LitJson;public class JSON : MonoBehaviour / Use this for initializationvoid Start ()#if UNITY_EDITORstring filepath = Application.dataPath +/StreamingAssets+/json.txt;#elif UNITY_IPHONEstring filepath = Application.dataPath +/Raw+/json.txt;#endif StreamReader sr= File.OpenText(filepath);stringstrLine = sr.ReadToEnd();
