BuildAssetBundleOptions.ChunkBasedCompression

描述

创建 AssetBundle 时使用基于语块的 LZ4 压缩。

这允许在从 AssetBundle 读取数据时进行实时解压缩。 使用此选项创建的 AssetBundle 在下载后会以压缩形式存储（位于磁盘缓存或内存中）。

//Create a folder (right click in the Assets folder and go to Create>Folder), and name it “Editor” if it doesn’t already exist
//Place this script in the Editor folder

//This script creates a new Menu named “Build Asset” and new options within the menu named “Normal” and “Chunk Based Compression”. Click these menu items to build an AssetBundle.

using UnityEngine;
using UnityEditor;

public class Example
{
    //Creates a new menu (Build Asset Bundles) and item (Normal) in the Editor
    [MenuItem("Build Asset Bundles/Normal")]
    static void BuildABsNone()
    {
        //Build AssetBundles with no special options
        //They will be written in the custom folder ("MyAssetBuilds") which needs to exist prior to this call.
        BuildPipeline.BuildAssetBundles("Assets/MyAssetBuilds", BuildAssetBundleOptions.None, BuildTarget.StandaloneOSX);
    }

    //Creates a new item (Chunk Based Compression) in the new Build Asset Bundles menu
    [MenuItem("Build Asset Bundles/Chunk Based Compression")]
    static void BuildABsChunk()
    {
        //Build the AssetBundles in this mode
        BuildPipeline.BuildAssetBundles("Assets/MyAssetBuilds", BuildAssetBundleOptions.ChunkBasedCompression, BuildTarget.StandaloneOSX);
    }
