unity3d动态加载脚本

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: /unity安装根目录\Unity\Editor\Data\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;

//TestDll 是资源的名字

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);

}
