1、什么是依赖关系

有时候一个模型所需要的东西可能在不同的包里面，例如蓝色立方体的模型和材质在不同的包（mode和head）里，这时需要加载两个包才能让这个球正常显示

2、如何获取依赖关系并加载

//加载AB包
AssetBundle ab = AssetBundle.LoadFromFile(Application.streamingAssetsPath + "/" + "model");//AssetBundle ab2 = AssetBundle.LoadFromFile(Application.streamingAssetsPath + "/" + "head");//获取依赖关系//加载主包AssetBundle abMain = AssetBundle.LoadFromFile(Application.streamingAssetsPath + "/" + "PC");//加载主包中的固定文件（固定写法）AssetBundleManifest abMainfest = abMain.LoadAsset<AssetBundleManifest>("AssetBundleManifest");//得到依赖信息（例如这个model）string[] strs = abMainfest.GetAllDependencies("model");//用得到的字符串去加载相应的包for (int i = 0; i < strs.Length; i++){print(strs[i]);AssetBundle.LoadFromFile(Application.streamingAssetsPath + "/" + strs[i]);}//ab = AssetBundle.LoadFromFile(Application.streamingAssetsPath + "/" + "head");//加载AB包资源//用这个重载，因为Lua不支持泛型GameObject obj = ab.LoadAsset("Cube",typeof(GameObject)) as GameObject;Instantiate(obj);GameObject obj2 = ab.LoadAsset("Sphere", typeof(GameObject)) as GameObject;Instantiate(obj2,new Vector3(1,1,1),Quaternion.identity);
