Does anyone know if there is a way to do something to the effect of

object.__type

or is there anyway to add in so the following would work

local myObj = object:new()

print( type( myObj ) )

would print something like say "object"

there is no metatable for the type function, you can modify the type function to check the metatable though... it is a messy workaround and will not work for protected metatables either

EDIT: added functionality to run the mt.__type if it is a function

EDIT2: simplified the code

local oldT=type
type=function(param)
if oldT(param)=="table" then
  local mt=getmetatable(param)
  if oldT(mt)=="table" and oldT(mt.__type)=="function" then
   return mt.__type(param)
  elseif oldT(mt)=="table" and mt.__type then
   return mt.__type
  end
end
return oldT(param)
end

as I said... messy

Damn just as I thought... I tried something to the effect of that and it didn't quite work how I wanted it to... I have another way to get to the desired outcome, just using type would have been nicer... oh well... thanks for the help

no problem I tested that one and it works perfectly....
