Hi, I just wonder, how can we register the const attributes and methods? Do I need to register them as a global? Cheers

You can register the const methods as normal object methods, just append const after the parameter list (just like in C++).

engine->RegisterObjectMethod("MyObj", "void func() const", asMETHOD(MyObj,func), asCALL_THISCALL);

The const attributes must be registered as globals though.
