Class registration problem

Robert Rouse · 2009-01-20T11:45:57

I have registered a C++ class successfully (according to return codes), but when I try to use it in a script, I get an "Expected Identifier" error. engine = asCreateScriptEngine(ANGELSCRIPT_VERSION); int r = engine->SetMessageCallback(asMETHOD(CLoad, GetScriptError), this, asCALL_THISCALL); assert( r >= 0 ); RegisterScriptString(engine); r = engine->RegisterObjectType("CEngine", sizeof(CEngine), asOBJ_VALUE | asOBJ_APP_CLASS_CDA); assert( r >= 0 ); r = engine->RegisterObjectBehaviour("CEngine", asBEHAVE_CONSTRUCT, "void f()", asMETHOD(CLoad, Constructor), asCALL_THISCALL); assert(r >= 0); r = engine->RegisterObjectBehaviour("CEngine", asBEHAVE_DESTRUCT, "void f()", asMETHOD(CLoad, Destructor), asCALL_THISCALL); assert(r >= 0); r = engine->RegisterObjectMethod("CEngine", "void ShowMessage(string &in)", asMETHOD(CEngine, ShowMessage), asCALL_THISCALL); assert( r >= 0 ); r = engine->RegisterObjectMethod("CEngine", "void Find(string &in)", asMETHOD(CEngine, FindGame), asCALL_THISCALL); assert( r >= 0 ); r = engine->RegisterObjectMethod("CEngine", "void LoadExtension(string &in)", asMETHOD(CEngine, Extension), asCALL_THISCALL); assert( r >= 0 ); Script void main() { CEngine blah; } Am I doing something wrong? Also, is it a bad idea to have the registered construction and destruction functions in another class? I'm trying not to put Angelscript code inside the C++ class. Finally, if I leave the body of the void main function empty, asserts are raised. Why is that?

That last error is probably due to opening the script file in text mode, instead of binary mode. If opening the script file in text mode, the line endings may get translated from CRLF to just LF, thus producing a shorted script buffer than the file size.

I'm passing the script text to Angelscript via a std::string. I'm using Angelscript inside of a browser plugin, so the script text comes from a text file on a web server. If I output it to a message box, it looks right. Would you suggest I do it another way?

Does the script length correspond with strlen(scrípt.c_str())?

Obviously the parser is trying to find more tokens beyond the end of the script, and the only way it will do that is if your telling AngelScript in AddScriptSection that the script is longer than it really is.

That's what it was. I messed up a memcpy which made me miss the null terminator. I was getting junk at the end and didn't notice. It was intermittent which made it fun to find.
