Unity WebGL MoonSharp崩溃问题

当前Unity的代码更新方案基本都选择的ULua，而我们项目还需要考虑Web平台，ULua不支持WebGL，所以决定选择MoonSharp。MoonSharp(http://www.moonsharp.org/)是一个纯C#实现的Lua解释器，支持多种平台。

测试环境：Unity5.4 + WebGL + MoonSharp 1.6.0.0

测试代码：

 double MoonSharpFactorial()
 {
     string script = @"
         -- defines a factorial function
         function fact (n)
             if (n == 0) then
                 return 1
             else
                 return n*fact(n - 1)
             end
         end

         return fact(5)";

     DynValue res = Script.RunString(script);
     return res.Number;
 }

在Web浏览器中却崩溃了，后经过定位发现是MoonSharp.Interpreter.Loaders.UnityAssetsScriptLoader.LoadResourcesWithReflection出错，Bug和我的修改已经在GitHub提交给作者了，预计很快会合并到主干代码中。

 void LoadResourcesWithReflection(string assetsPath)
 {
     try
     {
         Type resourcesType = Type.GetType("UnityEngine.Resources, UnityEngine");
         Type textAssetType = Type.GetType("UnityEngine.TextAsset, UnityEngine");

         MethodInfo textAssetNameGet = textAssetType.GetProperty("name").GetGetMethod();
         MethodInfo textAssetTextGet = textAssetType.GetProperty("text").GetGetMethod();

         MethodInfo loadAll = resourcesType.GetMethod("LoadAll",
             new Type[] { typeof(string), typeof(Type) });

         Array array = (Array)loadAll.Invoke(null, new object[] { assetsPath, textAssetType });//此处崩溃，估计是Unity导出代码有Bug

         for (int i = ; i < array.Length; i++)
         {
             object o = array.GetValue(i);

             string name = textAssetNameGet.Invoke(o, null) as string;
             string text = textAssetTextGet.Invoke(o, null) as string;

             m_Resources.Add(name, text);
         }
     }
     catch (Exception ex)
     {
 #if !PCL
         Console.WriteLine("Error initializing UnityScriptLoader : {0}", ex);
 #endif
     }
 }

可以改为

 void LoadResourcesWithReflection(string assetsPath)
 {
     try
     {
 #if UNITY_WEBGL
         UnityEngine.TextAsset[] arrayTextAsset = UnityEngine.Resources.LoadAll<UnityEngine.TextAsset>(assetsPath);
         for (int i = ; i < arrayTextAsset.Length; i++)
         {
             UnityEngine.TextAsset text = arrayTextAsset[i];
             m_Resources.Add(text.name, text.text);
         }
         return;
 #endif

         Type resourcesType = Type.GetType("UnityEngine.Resources, UnityEngine");
         Type textAssetType = Type.GetType("UnityEngine.TextAsset, UnityEngine");

         MethodInfo textAssetNameGet = textAssetType.GetProperty("name").GetGetMethod();
         MethodInfo textAssetTextGet = textAssetType.GetProperty("text").GetGetMethod();

         MethodInfo loadAll = resourcesType.GetMethod("LoadAll",
             new Type[] { typeof(string), typeof(Type) });

         Array array = (Array)loadAll.Invoke(null, new object[] { assetsPath, textAssetType });

         for (int i = ; i < array.Length; i++)
         {
             object o = array.GetValue(i);

             string name = textAssetNameGet.Invoke(o, null) as string;
             string text = textAssetTextGet.Invoke(o, null) as string;

             m_Resources.Add(name, text);
         }
     }
     catch (Exception ex)
     {
 #if !PCL
         Console.WriteLine("Error initializing UnityScriptLoader : {0}", ex);
 #endif
     }
 }
