關於unity中Assetbundle動態加載

    關於unity中Assetbundle動態加載，剛剛在網上學了一點，現在就分享給大家，親測有用

    

a.將腳本ExportAssetBundles.cs放到Editor文件夾下（沒有可以新建），會在asset菜單下新增兩個功能鍵（也可以在腳本中直接調用）

ExportAssetBundles腳本的代碼：

using UnityEngine;
using System.Collections;
using UnityEditor;

public class ExportAssetBundles : Editor
{
    //在Unity編輯器中添加菜單
    [MenuItem("Assets/Build AssetBundle From Selection")]
    static void ExportResourceRGB2()
    {
        // 打開保存面板，獲得用戶選擇的路徑
        string path = EditorUtility.SaveFilePanel("Save Resource", "", "New Resource", "assetbundle");

        if (path.Length != 0)
        {
            // 選擇的要保存的對象
            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()
    {
        // 打開保存面板，獲得用戶選擇的路徑
        string path = EditorUtility.SaveFilePanel("Save Resource", "", "New Resource", "unity3d");

        if (path.Length != 0)
        {
            // 選擇的要保存的對象
            Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);
            // 注意此處要保存的場景位於Assets目錄下的Scenes文件夾下，可視情況而定
            string[] scenes = { "Assets/Scenes/Scene1.unity" };
            //打包
            BuildPipeline.BuildPlayer(scenes, path, BuildTarget.StandaloneWindows, BuildOptions.BuildAdditionalStreamedScenes);
        }
    }
}

    

    b.分別選中資源和場景點擊Assets菜單最下方的打包資源和場景選項，自由選擇路徑與名稱，只要在加載腳本bundleLoad.cs中對應即可

bundleLoad腳本爲：

using UnityEngine;
using System;
using System.Collections;

public class bundleLoad : MonoBehaviour {
            //注意資源鏈接
    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()
    {
        //下載assetbundle，加載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);
        }
        //下載場景，加載場景
        using (WWW scene = new WWW(SceneURL))
        {
            yield return scene;
            AssetBundle bundle = scene.assetBundle;
            //bundle.Load();
            //注意場景名稱
            Application.LoadLevel("Scene1");
        }

    }
}

 

    c.新建場景,將加載腳本掛在場景主相機或者課執行的對象上使腳本運行

希望對初學者有幫助
