buildAsset分析(一)——AssetUnit

这个文件主要定义了AssetUnit这个数据结构。保存了单个文件的各种信息。AssetUnit.cs：

using UnityEngine;using UnityEditor;using System.Collections;using System.Collections.Generic;public class AssetUnit{    public string mPath;                            //文件路径相对Asset          public string mName;                            //文件名称,无后缀名称    public string mSuffix;                          //后缀    public int mLevel;                              //层数    public int mIndex;                              //索引    public int mAssetSize;                          //保存该Asset的打包文件大小    public List<string> mAllDependencies;           //所有依赖    public List<AssetUnit> mNextLevelDependencies;  //下层依赖    public List<AssetUnit> mDirectUpperDependences; //直接上层依赖,用于判定assetbundle加载后是否可以马上删除    public AssetUnit(string path)    {        mAssetSize = 0;        mPath = path;        mName = BuildCommon.getFileName(mPath, true);        mSuffix = BuildCommon.getFileSuffix(mName);        mLevel = BuildCommon.getAssetLevel(mPath);        mAllDependencies = new List<string>();        mNextLevelDependencies = new List<AssetUnit>();        string[] deps = AssetDatabase.GetDependencies(new string[] { mPath });        foreach (string file in deps)        {            string suffix = BuildCommon.getFileSuffix(file);            //if (file == mPath || suffix == "dll" || suffix == "cs")            if (file == mPath || suffix == "dll")                continue;            mAllDependencies.Add(file);        }        mDirectUpperDependences = new List<AssetUnit>();    }}
