关于unity中Assetbundle动态加载

    关于unity中Assetbundle动态加载，刚刚在网上学了一点，现在就分享给大家，亲测有用

    

a.将脚本ExportAssetBundles.cs放到Editor文件夹下（没有可以新建），会在asset菜单下新增两个功能键（也可以在脚本中直接调用）

ExportAssetBundles脚本的代码：

using UnityEngine;
using System.Collections;
using UnityEditor;

public class ExportAssetBundles : Editor
{
    //在Unity编辑器中添加菜单
    [MenuItem("Assets/Build AssetBundle From Selection")]
    static void ExportResourceRGB2()
    {
        // 打开保存面板，获得用户选择的路径
        string path = EditorUtility.SaveFilePanel("Save Resource", "", "New Resource", "assetbundle");

        if (path.Length != 0)
        {
            // 选择的要保存的对象
            Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);
            //打包
            BuildPipeline.BuildAssetBundle(Selection.activeObject, selection, path, BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets, BuildTarget.StandaloneWindows);
        }
    }
    [MenuItem("Assets/Save Scene")]
    static void ExportScene()
    {
        // 打开保存面板，获得用户选择的路径
        string path = EditorUtility.SaveFilePanel("Save Resource", "", "New Resource", "unity3d");

        if (path.Length != 0)
        {
            // 选择的要保存的对象
            Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);
            // 注意此处要保存的场景位于Assets目录下的Scenes文件夹下，可视情况而定
            string[] scenes = { "Assets/Scenes/Scene1.unity" };
            //打包
            BuildPipeline.BuildPlayer(scenes, path, BuildTarget.StandaloneWindows, BuildOptions.BuildAdditionalStreamedScenes);
        }
    }
}

    

    b.分别选中资源和场景点击Assets菜单最下方的打包资源和场景选项，自由选择路径与名称，只要在加载脚本bundleLoad.cs中对应即可

bundleLoad脚本为：

using UnityEngine;
using System;
using System.Collections;

public class bundleLoad : MonoBehaviour {
            //注意资源链接
    private string BundleURL = "file:///E:/UnityTest/MapTest1/mapTest1/cube.assetbundle";
    private string SceneURL = "file:///E:/UnityTest/Scene1.unity3d";

    void Start()
    {
        //BundleURL = "file//"+Application.dataPath+"/cube.assetbundle";
        Debug.Log(BundleURL);
        StartCoroutine(DownloadAssetAndScene());
    }

    IEnumerator DownloadAssetAndScene()
    {
        //下载assetbundle，加载Cube
        using (WWW asset = new WWW(BundleURL))
        {
            yield return asset;
            //AssetBundle bundle = asset.assetBundle;
            //AssetBundle bundle = (AssetBundle)DownloadAsset.assetBundle.LoadAsset(asset);
            //bundle.LoadAll();
            Instantiate(asset.assetBundle.mainAsset);
            asset.assetBundle.Unload(false);
            yield return new WaitForSeconds(3);
        }
        //下载场景，加载场景
        using (WWW scene = new WWW(SceneURL))
        {
            yield return scene;
            AssetBundle bundle = scene.assetBundle;
            //bundle.Load();
            //注意场景名称
            Application.LoadLevel("Scene1");
        }

    }
}

    c.新建场景,将加载脚本挂在场景主相机或者课执行的对象上使脚本运行

希望对初学者有帮助
