1.AssetBundle打包
1.1设置资源的命名和后缀
命名只支持小写

1.AssetBundle打包
1.1设置资源的命名和后缀
命名只支持小写
1.2创建Editor文件夹在里面创建编辑器打包AssetBundle的脚本
using UnityEditor;
using System.IO;public class CreateAssetBundles {[MenuItem(Assets/Build AssetBundles)]static void BuildAllAssetBundles(){string dir AssetBundles;if( Directory.Exists(dir)false){Directory.CreateDirectory(dir);}BuildPipeline.BuildAssetBundles(dir, BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows64);}
}压缩方式 BuildAssetBundleOptions.None使用LZMA算法压缩压缩包下但加载时间长 BuildAssetBundleOptions.UncompressedAssetBundle不压缩包大加载快 BuildAssetBundleOptions.ChunkBasedCompression:使用LZ4压缩压缩率没有LZMA高但是我们可以加载指定资源而不用解压全部 注意使用LZ4压缩可以获得可以跟不压缩相媲美的加载速度而且比不压缩文件要小
1.3选择菜单Assers-》点击Build AssetBundles 进行打包 得到打包后的文件
2.AssetBundle加载方式
原则上在使用资源之前需要先加载材质包再创建prefab防止材质丢失。share.unity3d为cubewallf的材质贴图包share.unity3d和cubewall.unity3d加载先后顺序不影响
加载方式1本地加载 AssetBundle.LoadFromFile
AssetBundle ab AssetBundle.LoadFromFile(AssetBundles/share.unity3d);AssetBundle ab AssetBundle.LoadFromFile(AssetBundles/cubewall.unity3d);GameObject wallPrefab ab.LoadAssetGameObject(CubeWall);Instantiate(wallPrefab);加载方式2 内存中加载异步 AssetBundle.LoadFromMemoryAsync
IEnumerator LoadFromMemoryAsync(string path){AssetBundleCreateRequest createRequest AssetBundle.LoadFromMemoryAsync(File.ReadAllBytes(path));yield return createRequest;AssetBundle bundle createRequest.assetBundle;var prefab bundle.LoadAssetGameObject(MyObject);Instantiate(prefab);}内存中加载同步 AssetBundle.LoadFromMemory
AssetBundle abAssetBundle.LoadFromMemory(File.ReadAllBytes(path));加载方式3网络加载 UnityWebRequestAssetBundle
IEnumerator InstantiateObject()
{string uri file:/// Application.dataPath /AssetBundles/ assetBundleName; UnityEngine.Networking.UnityWebRequestAssetBundle request UnityEngine.Networking.UnityWebRequestAssetBundle.GetAssetBundle(uri, 0);yield return request.SendWebRequest();AssetBundle bundle DownloadHandlerAssetBundle.GetContent(request);GameObject cube bundle.LoadAssetGameObject(Cube);GameObject sprite bundle.LoadAssetGameObject(Sprite);Instantiate(cube);Instantiate(sprite);
}弃用网络加载2 LoadFromCacheOrDownload(string url, int version);
IEnumerator Start(){while (!Caching.ready)yield return null;using (var www WWW.LoadFromCacheOrDownload(https://myserver.com/myassetBundle.unity3d, 5)){yield return www;if (!string.IsNullOrEmpty(www.error)){Debug.Log(www.error);yield return null;}var myLoadedAssetBundle www.assetBundle;var asset myLoadedAssetBundle.mainAsset;}}API2LoadFromCacheOrDownload(string url, int version, uint crc); crc表示校验完整性crc在.mainifest文件里
3.通过Manifest文件得到某个包的依赖
AssetBundles.manifest 里面包含所有包对应的依赖 代码
AssetBundle manifestAB AssetBundle.LoadFromFile(AssetBundles/AssetBundles);//固定为AssetBundles
AssetBundleManifest manifest manifestAB.LoadAssetAssetBundleManifest(AssetBundleManifest);//固定为“AssetBundleManifest”
string[] strs manifest.GetAllDependencies(cubewall.unity3d);
foreach (string name in strs) {print(name);//share.unity3dAssetBundle.LoadFromFile(AssetBundles/ name); //加载cubewall.unity3d的依赖包
}4.AssetBundle的卸载
卸载可以减少内容的使用不当的卸载有可能导致丢失材质丢失bug红等AssetBundle.Unload(true) 卸载所有资源即使有资源被使用着推荐这个方法卸载前确保依赖的包不被其他物体使用了。可以在切换场景是loading scene阶段去卸载AssetBundle.Unload(false) 卸载所有没有被使用的资源一般不用这个方法会导致某些资源不被卸载导致内存被滥用个别资源的卸载 1.通过Resources.UnloadUnusedAssets 2.场景切换的时候自动调用Resources.UnloadUnusedAssets
