Unity Export XML configuration file, load scene dynamically

Reference: http://www.xuanyusong.com/archives/1919

http://www.omuying.com/article/48.aspxMain functions:1. Export the scene's configuration file2. Export the assetbundle of resources in the current scene3. The client obtains the configuration file from the server4. Parse the configuration file and download Assetbundle according to the configuration file5. Instantiating and restoring a scene1. Scene settings: Set the scene resource you want to export to preset 2. Export the scene configuration as an XML file [Code]csharpcode:

Using unityengine;using unityeditor;using system.collections;using system.collections.generic;using System.Xml; Using system.io;using System.text;public class Exportscenetoxml:editor {[MenuItem ("Assets/export Scene to XML from Selec tion ")]static void ExportXML () {String path = Editorutility.savefilepanel (" Save Resource "," "," New Resource "," xml "); Path.

3. Package The Presets as Assetbundle and upload them to the serverPackage Assetbundle Editor Script:[Code]csharpcode:
