c# - Unity3D 中是否有针对 IL2Cpp 构建的运行时代码编译的解决方案？

Question

我正在尝试在运行时在 Unity3D 中为 IL2CPP 构建 64 位 Android 编译 C# 代码。

我有一串代码，我想动态编译和执行。我尝试过的事情是:

1. https://github.com/aeroson/mcs-ICodeCompiler
   
2. https://github.com/SoapCode/UCompile/tree/master/Assets/UCompile
   
3. https://assetstore.unity.com/packages/tools/integration/roslyn-c-runtime-compiler-142753#reviews
   

但我了解到，以上所有内容均不适用于 IL2Cpp 构建。

下面的代码是使用上面提到的第二个 Github 存储库执行的。

CSScriptEngine engine = new CSScriptEngine();
engine.AddUsings("using UnityEngine; using System; using System.Collections.Generic;");
engine.AddOnCompilationFailedHandler(OnCompilationFail);
IScript result = engine.CompileCode(@codeToConvert);

第二个插件:

Answer 1

您不能将 dynamic 关键字与 IL2CPP 一起使用 - 与 IL2CPP 的工作方式有关。据我所知，IL2CPP 可能永远对此提供支持。

转换成一个显式对象并使用它，也许吧。
