Unity -- AssetBundle(本地资源加载和加载依赖关系)

1.本地资源加载

1).建立Editor文件夹

2).建立StreamingAssets文件夹和其Windows的子文件夹

将下方第一个脚本放入Editor 里面

脚本一  资源打包AssetBundle的所有标签资源

using UnityEngine; using UnityEditor; public class Tools { [MenuItem("Tools/buildAB")] //编辑器扩展
    public static void Building() { Debug.LogError("111"); string _adPath = Application.streamingAssetsPath + "\\Windows";//路径
 BuildPipeline.BuildAssetBundles(_adPath, BuildAssetBundleOptions.None, BuildTarget.StandaloneLinux64);  //自动检测有AssetBundle标签的预制体,并进行资源压缩. //固定格式
 } }

 

资源加载

using System.Collections; using System.Collections.Generic; using UnityEngine; public class Load2 : MonoBehaviour { // Use this for initialization
    void Start () { //本地必须加入 file:// 这样子www才能进行访问
        string _abpath ="file://" +Application.streamingAssetsPath + "/Windows/sp"; StartCoroutine("Creat",_abpath); } // Update is called once per frame
    void Update () { } IEnumerator Creat(string path) { using (WWW lo=new WWW(path)) { yield return lo; if (lo != null) { AssetBundle ab = lo.assetBundle; if (ab != null) { GameObject obj = ab.LoadAsset<GameObject>("Cube"); Instantiate(obj); } } else { Debug.LogError("加载失败"); } } }

2.加载依赖关系

using System.Collections; using System.Collections.Generic; using UnityEngine; public class LoadManCtr : MonoBehaviour { // Use this for initialization
    public string ABName; string _abPath; string _manpath; private List<AssetBundle> ManListAB; void Start () { ManListAB = new List<AssetBundle>(); _abPath = Application.streamingAssetsPath + "/Windows/"; _manpath = Application.streamingAssetsPath + "/Windows/Windows"; //查找依赖关系
        #region 加载依赖 AssetBundle _manAB = AssetBundle.LoadFromFile(_manpath); //固定格式
        AssetBundleManifest manifest = _manAB.LoadAsset<AssetBundleManifest>("AssetBundleManifest");  string[] dependencies = manifest.GetAllDependencies(ABName); Debug.LogError(dependencies.Length); //加载依赖
        if (dependencies.Length != 0) { foreach (string s in dependencies) { Debug.Log(s); //挨个加载依赖关系
                ManListAB.Add(LoadABByName(s)); //存在内存中
 } } #endregion
        //依赖加载完毕 圆柱 立方体
        AssetBundle _ab = AssetBundle.LoadFromFile(_abPath + ABName); GameObject copyObj = _ab.LoadAsset<GameObject>("Capsule"); Instantiate(copyObj); //释放ab依赖的内存
        foreach (var v in ManListAB) { v.Unload(false); } _ab.Unload(false);//不从场景里面删除 //true 场景删除
        AssetBundle _ab01 = AssetBundle.LoadFromFile(_abPath + ABName);//_ab.Unload(false); 没有这句话会重复加载
        GameObject copyObj01 = _ab01.LoadAsset<GameObject>("Capsule"); Instantiate(copyObj01,Vector3.one,Quaternion.identity); } // Update is called once per frame
    void Update () { } private AssetBundle LoadABByName(string name) { return AssetBundle.LoadFromFile(_abPath + name); } }
