unity 代码设置要打包的AssetBundle

1、AssetBundle 在unity 5 中要先标志好，然后就可以打包时根据平台直接打包即可，手动设置不现实，根据文件路径来确定其归属是一个不错的选择

把需要打包的资源都存在 <span style="font-family: Arial, Helvetica, sans-serif;">AssetBundle 中，然后在Editor 目录加入下面代码</span>

using UnityEngine;using UnityEditor;using System.Collections;using System;using System.IO;public class AssetBundlePostProcessor : AssetPostprocessor{private const string assetBundleRootPath = "Assets/AssetBundle/";static void OnPostprocessAllAssets (string[] importedAssets, string[] deletedAssets, string[] movedAssets, string[] movedFromAssetPaths){foreach (var str in importedAssets){bool isChanged = CheckModifyIsTarget (str);if (isChanged){Debug.Log("isChanged Asset: " + str);SetAssetBundleName (str);}}}// 检测是否是我希望设置的文件static bool CheckModifyIsTarget(string path){if(Directory.Exists (path)){return false;}string fileName = Path.GetFileName (path);if (string.IsNullOrEmpty (fileName) || fileName.EndsWith (".meta")){return false;}else{return path.Contains (assetBundleRootPath);}}static void SetAssetBundleName(string path){string asName = GetAssetNameByPath (path);AssetImporter importer = AssetImporter.GetAtPath (path);importer.SetAssetBundleNameAndVariant (asName, "");}static string GetAssetNameByPath(string path){int index = assetBundleRootPath.Length;string substr = path.Substring (index);int lastFlashIndex = substr.LastIndexOf ('/');return substr.Substring (0, lastFlashIndex);}}

2、在网络上看到别人的做法，感觉更好，那就是在打包的时候先设置好，然后再打包。因为上面 1 的方法没有 reimport 就可能会有问题，而这个方法是在打包时全部设置一次，挺好的。。不过就是可能打包时间比较长。。。每次打包都设置一次，似乎也会重复，如果要打包两次可能就会重复
