Whenever I call RegisterObjectType it returns -5. It's independent of passed parameters. When I pass asOBJ_REF - RegisterObjectType("Info", sizeof(Info), asOBJ_REF) - it works, and only then. I am using samples/tutorial/source/main.cpp (AS 2.13.0) as a framework and RegisterObjectType is called at the end of ConfigureEngine. What's wrong?

I think it might be because you're not registering the ADDREF & RELEASE callbacks via RegisterObjectBehaviour.

I'm in a bit of a hurry right now, so I'm just going to refer you to the manual:

Registering a C++ class

What a shame.. I was truly certain that the "old" asOBJ_CLASS I found over the net was corresponding to the "new" asOBJ_APP_CLASS.. asOBJ_VALUE | asOBJ_POD | asOBJ_APP_PRIMITIVE is what I was looking for.

Well, next time I will look to the manual first ;)
Thank you a lot!
