今天打Bundle的时候Unity提示错误

An asset is marked with HideFlags.DontSave but is included in the build:Asset: 'Library/unity editor resources'Included from scene: 'Assets/wyft.unity'(You are probably referencing internal Unity data in your build.)UnityEditor.BuildPipeline:BuildAssetBundles(String, BuildAssetBundleOptions, BuildTarget)BuildAssetbundle:Build() (at Assets/script/Editor/AssetBundle/BuildAssetBundle.cs:11)

到Unity论坛搜索，得到答案是 UILabel 引用了Unity自带的字体

于是乎拉上小伙伴一起把所有的Prefab过一遍，找了一会儿我就烦了……太慢了这边急着打包

决定还是写段代码来干活

前提：

Prefab是文本格式保存。

Prefab里面记录着各种文件、代码引用以及其它的一些设置、类的值等等。

在Unity中，每个文件都有一个UID 存储在meta文件中，在Prefab中就只能看到一长串的UID，如果是引用了Unity自带的资源，那么UID是0！

根据这个特性，来遍历读取所有的Prefab，寻找其中UID为0的Prefab然后修改。

图中 fileID:0 就是代表这个UILabel 引用了Unity的字体

有时候尽管在编辑器中修改了字体，但是Prefab中仍然残留这 TrueTypeFont对Unity内置字体的引用，这个就手动删除把。

附上代码：

/************************************************ * 文件名:CheckUnityFont.cs * 描述:CheckUnityFont 检测是NGUI的UILabel中引用了Unity自带字体 * 创建人:陈鹏 * 创建日期：201601015 * ************************************************/using UnityEngine;using System.Collections;using System.Collections.Generic;using UnityEditor;using System.IO;public class CheckUnityFont : MonoBehaviour{    // 在菜单来创建 选项 ， 点击该选项执行搜索代码        [MenuItem("Tools/Check Unity Font")]    static void Check()    {        string[] tmpFilePathArray = Directory.GetFiles(Application.dataPath, "*.*", SearchOption.AllDirectories);        EditorUtility.DisplayProgressBar("CheckUnityFont", "CheckUnityFont", 0f);        for (int i=0;i<tmpFilePathArray.Length;i++)        {            EditorUtility.DisplayProgressBar("CheckUnityFont", "CheckUnityFont",( i*1.0f)/tmpFilePathArray.Length);            string tmpFilePath = tmpFilePathArray[i];            if(tmpFilePath.EndsWith(".prefab"))            {                StreamReader tmpStreamReader = new StreamReader(tmpFilePath);                string tmpContent = tmpStreamReader.ReadToEnd();                if(tmpContent.Contains("mFont: {fileID: 0}"))                {                    Debuger.LogError(tmpFilePath);                }            }            if (tmpFilePath.EndsWith(".prefab"))            {                StreamReader tmpStreamReader = new StreamReader(tmpFilePath);                string tmpContent = tmpStreamReader.ReadToEnd();                if (tmpContent.Contains("guid: 0000000000000000d000000000000000"))                {                    Debuger.LogError(tmpFilePath);                }            }        }        EditorUtility.ClearProgressBar();    }}
