c# - IL2CPP Compiler Runtime Errors for Unity3D iOS 64-bit -

i have unity3d mobile chess app porting 32-bit 64-bit unity 3d 4.6.5f1. it's using opengls2.0, .net 2.0 libraries, , universal binaries being generated.

i getting runtime error in debugger says following:

 nullreferenceexception: null value found object instance required.   @ <privateimplementationdetails>..ctor () [0x00000] in <filename unknown>:0    @ valilscriptobject.update () [0x00000] in <filename unknown>:0    @ system.collections.generic.dictionary`2+shimenumerator[boo.lang.runtime.dynamicdispatching.dispatcherkey,boo.lang.runtime.dynamicdispatching.dispatcher].get_current () [0x00000] in <filename unknown>:0  system.collections.generic.shimenumerator:get_current() 

(filename: not available on il2cpp line: 4294967295)

it compiles fine using mono 2.0 port il2cpp 64-bit universal binary throws error.

the function it's referencing update() appears fine.

void update () {     if(request.length>0)     {         string answ="";         answer=engine1.getnextmove(request, null, deep);         request="";         if(answer.length>0) answ=answer.substring(0,2)+"-"+answer.substring(2,2);         if(answer.length>4) answ+="="+(answer.substring(4,1)).toupper();         ((textmesh)getcomponent(typeof(textmesh))).text=answ;          //application.externalcall("jsanswer", answ);          (gameobject.find("script2")).sendmessage("engineanswer",answ);     }  } 

it's using valil chess engine (written in c#) appropriate answers (next move). works fine in mono 2.0 failing il2cpp. ideas?

i found answer. when chessengine initialized there chessengine.openingbook class that's initialized. took out class altogether, , worked charm. class looks like:

using system; using system.io; using system.collections.generic; using system.reflection; //using valil.chess.engine.properties;  namespace valil.chess.engine {     public sealed partial class chessengine     {         // hashtable board hash key , list of moves board configuration value         public static dictionary<int, list<short>> book;          // helps choose move when list contains more 1         private random random;          /// <summary>         /// initializes opening book.         /// </summary>         private void initializeopeningbook()         {             // initialize random generator             random = new random(unchecked((int)datetime.now.ticks));              int settings_default_openingbooksize = 2755;             //int settings_default_openingbookbytesize = 16530;              //assembly assembly = assembly.getexecutingassembly();             //string[] ss = assembly.getmanifestresourcenames();              // there no file & manifest assembly in unity3d free...             // so, class obookmem opening book!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!             stream readstream = assembly.getexecutingassembly().getmanifestresourcestream("valil_silverlightchess.book.bin");              // "book.bin" file binary file pattern: int,short,int,short etc.             // 4-byte int represent board hash, following 2-byte short move (the first byte represents starting square, second 1 ending square)              // read "book.bin" , put values in hashtable             try             {                  using (binaryreader br = new binaryreader( readstream ))  //                using (binaryreader br = new binaryreader(new bufferedstream(assembly.getexecutingassembly().getmanifestresourcestream("valil.chess.engine.book.bin"), settings.default.openingbookbytesize))) //                using (binaryreader br = new binaryreader(assembly.getexecutingassembly().getmanifestresourcestream("book.bin")))                   {                     book = new dictionary<int, list<short>>(settings_default_openingbooksize);                      (int = 0; < settings_default_openingbooksize; i++)                     {                         int hash = br.readint32();                         short move = br.readint16();                          // if hashtable contains hash, add move list                         // otherwise create new list , add pair hashtable                         if (book.containskey(hash))                         {                             book[hash].add(move);                         }                         else                         {                             list<short> list = new list<short>(1);                             list.add(move);                             book.add(hash, list);                         }                     }                 }             }             catch             {             }         }     } } 

i think il2cpp compiler doesn't system.reflection , dictionary , list types.
