1.先创建Asset序列化（单个文件夹所在文件夹路径，会遍历这个文件夹所有的Prefab，所有的Prefab名字不能重复，必须保证名字得唯一性），配置好ConfigAB表

4.先工具栏初始化运行 Tool/AB打包 然后反序列化加载 测试代码如下
void TextLoadAB()
{
TextAsset textAsset = Resources.Load<TextAsset>("Bytes/AssetBundleConfig");
using (MemoryStream stream = new MemoryStream(textAsset.bytes))
{
BinaryFormatter binaryFormatter = new BinaryFormatter();
AssetBundleConfig textSerilize = (AssetBundleConfig)binaryFormatter.Deserialize(stream);
string path = "Assets/GameData/Prefabs/Attack.prefab";
uint crc = CRC32.GetCRC32(path);
Debug.Log(textSerilize.ABList.Count);
ABBase aBBase = null;
for (int i = 0; i < textSerilize.ABList.Count; i++)
{
if (textSerilize.ABList[i].Crc == crc)
{
aBBase = textSerilize.ABList[i];
}
Debug.Log(textSerilize.ABList[i].Path);
}
for (int i = 0; i < aBBase.ABDependce.Count; i++)
{
Debug.Log(aBBase.ABDependce[i]);
AssetBundle.LoadFromFile(Application.streamingAssetsPath + "/" + aBBase.ABDependce[i]);
}
AssetBundle assetBundle = AssetBundle.LoadFromFile(Application.streamingAssetsPath + "/" + aBBase.ABName);
GameObject obj = GameObject.Instantiate(assetBundle.LoadAsset<GameObject>(aBBase.ABName));
}
}
