Hey guys ive tried to register a print( string ∈ ) method which was declared in a class.. i did it this way: r = this->engine->RegisterGlobalFunction("void Print(string ∈)", asMETHOD(TScriptManager,PrintString), asCALL_STDCALL); 1st of all, i have no idea wheater to use the asCALL_STDCALL or the asCALL_THISCALL macro but asCALL_STDCALL seems to work .. if i call the main function in this script: <void main() { }> it works w/o any problems, but if i call it this script <void main() { print("Hello"); }> the program crashes and visual studio opens the file "as_scriptengine.cpp" showing these lines: #ifndef AS_NO_CLASS_METHODS if( i->callConv == ICC_THISCALL ) { union { asSIMPLEMETHOD_t mthd; asFUNCTION_t func; } p; p.func = (void (*)())(i->func); void (asCSimpleDummy::*f)(void *) = (void (asCSimpleDummy::*)(void *))(p.mthd); (((asCSimpleDummy*)obj)->*f)(param); } else #endif if( i->callConv == ICC_CDECL_OBJLAST ) so where could the error be?
