Re: Metatables, C and Script...

All 'obj:method' calls must pass 'obj' as the first parameter to function, 
no metter what type 'obj' is. So it's extremely wierd if it doesn't. I 
haven't tried this on objects, but it works well with strings and numbers. 
Maybe I couldn't understand what your problem is.
