AssetBundle

1.打包

将要打包的资源在inspector中的预览窗口下设置要打包在AssetBundles下的路径和后缀名（可任意取）。新建一个C#脚本，脚本内容如下：

using System.IO;
using UnityEditor;
 
public class CreateAssetBundles 
{
    [MenuItem("Assets/Build AssetBundles")]//生成菜单目录
    static void BuildAllAssetBundles()
    {
        string assetBundleDirectory = "Assets/AssetBundles";//指定AssetBundles文件夹的目录
        if (!Directory.Exists(assetBundleDirectory))
        {
            Directory.CreateDirectory(assetBundleDirectory);//如果没有，则创建文件夹
        }
        BuildPipeline.BuildAssetBundles(assetBundleDirectory, BuildAssetBundleOptions.None,BuildTarget.StandaloneWindows);
    }
}

脚本无需挂载，在菜单Assets下点击新创建的Build AssetBundles，即可在指定文件夹创建AssetBundle.

2.读取

场景中物体上挂载一个脚本，脚本代码如下：

using UnityEngine;
 
public class LoadAssetBundle : MonoBehaviour
{
    void Start()
    {
        AssetBundle bundle = AssetBundle.LoadFromFile("Assets/AssetBundles/this/wall.ab");//找到AB包
        GameObject cubeWall = bundle.LoadAsset<GameObject>("CubeWall");//找到AB包中的物体
        Instantiate(cubeWall);//实例化物体
    }
}
