BuildAssetBundleOptions.ChunkBasedCompression

설명

Use chunk-based LZ4 compression when creating the AssetBundle.

This allows realtime decompression when reading data from the AssetBundle. AssetBundles created with this option are stored in compressed form after download (both in disk cache or memory).

//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);
    }
}
