Unity 通过XML保存场景物体信息

在项目工程中，将此脚本放置Editor文件夹中即可，在菜单栏中可以使用该命令导出场景信息内容保存为xml，文件存储到StreamingAssets文件夹中。

using System.Xml;
using UnityEditor;
using UnityEditor.SceneManagement;
using UnityEngine;

public class ExportSceneInfoToXML : Editor
{

    [MenuItem("Tool/ExportSceneInfoToXML")]
    static void ExportXML()
    {
        string filepath = Application.streamingAssetsPath + @"/sceneInfoXML.xml";
        if (File.Exists(filepath))
        {
            File.Delete(filepath);
        }
        XmlDocument xmlDoc = new XmlDocument();
        XmlElement root = xmlDoc.CreateElement("scenes");
        //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)
            {
                //得到当前场景的名称
                string name = s.path;
                //打开这个场景
                EditorSceneManager.OpenScene(name);
