Re: scripting via COM?

I don't think anyone has pointed this out yet, but COM objects are  
not inherently scriptable in and of themselves.  Anything scriptable  
by .NET, VB and other such languages has to implement IDispatch.  So  
adding scriptability to your engine won't be as simple as just  
deriving everything from IUnknown.  For starters, I'm guessing that  
all your methods that you wish to expose aren't already returning  
HRESULTs.

Trying to implement game engine scriptability through COM Automation  
has to be just about the most painful way you could go.
