本文记录如何通过unity3d进行脚本资源打包加载
1、创建TestDll.cs文件
public class TestDll : MonoBehaviour {
void Start () {
print(“Hi U_tansuo!”);
}
}
2、生成dll文件
（1）使用vs打包
（2） 使用mono打包
(3) 命令行打包 mac下（亲测）： /Applications/Unity/Unity.app/Contents/Frameworks/Mono/bin/gmcs -r:/Applications/Unity/Unity.app/Contents/Frameworks/Managed/UnityEngine.dll -target:library 脚本路径
win下（未试过）：mcs -r:/Applications/Unity/Unity.app/Contents/Frameworks/Managed/UnityEngine.dll -target:library 脚本路径
3、更改文件后缀
至关重要一步 更改上一步生成的TestDLL.dll 为 TestDLL.bytes 否则 打包加载会错
4、使用 BuildPipeline.BuildAssetBundle进行打包 资源为 TestDll.unity3d
5、加载
IEnumerator Test()
{
string url=”file://”+Application.dataPath+”/TestDll.unity3d”;
print(url);
WWW www = WWW.LoadFromCacheOrDownload (url, 1);
// Wait for download to complete
yield return www;
// Load and retrieve the AssetBundle
AssetBundle bundle = www.assetBundle;
TextAsset txt = bundle.Load(“TestDll”, typeof(TextAsset)) as TextAsset;
print(txt.bytes.Length);
// Load the assembly and get a type (class) from it
var assembly = System.Reflection.Assembly.Load(txt.bytes);
var type = assembly.GetType(“TestDll”);
// Instantiate a GameObject and add a component with the loaded class
gameObject.AddComponent(type);
}
