[原] 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);
    }
