Unity之C#代碼自動更新原理總結

步驟：

1.創建C# dll 空工程TestCoreDll

2.添加庫引用(該unity3d所需要用到dll,unity3d工程目錄下Library\ScriptAssemblies中的庫)

3.拷貝unity客戶端代碼至TestCoreDll工程目錄下

4.點擊菜單欄生成按鈕下重新生成TestCoreDll，即生成TestCoreDll.dll文件

5.將TestCoreDll.dll備份至unity3d工程目錄下，並修改器后綴名為TestCoreDll.bytes

6.使用BuildPipeline.BuildAssetBundle將TestCoreDll.bytes編譯成對應的assetbundle，即TestCoreDll.assetbundle

7.使用程序集Assembly加載使用TestCoreDll.assetbundle中代碼，至此C#代碼自動更新原理結束

代碼片段：如下

生成dll文件：

msbuild "%targetProjectName%.csproj" /p:Configuration=Release /p:DefineConstants="TRACE;UNITY_5;USE_ANIMEVENT_INT_PARAMETER;UNITY_ANDROID;LOAD_DLL" /m /nologo /clp:ErrorsOnly /flp1:logfile=errors.txt;errorsonly

生成assetBundle文件

BuildPipeline.BuildAssetBundle(obj, null, "Assets/StreamingAssets/ClientCore.assetbundle", BuildAssetBundleOptions.CollectDependencies, target);

使用程序集加載引用代碼：

WWW www = new WWW(path);

AssetBundle bundle = www.assetBundle;

TextAsset asset = bundle.LoadAsset("TestCoreDll", typeof(TextAsset)) as TextAsset;

System.Reflection.Assembly assembly = System.Reflection.Assembly.Load(asset.bytes);
Type script = assembly.GetType("TestScript");

if (script != null)
{
gameObject.AddComponent(script);
}
