Re: Type definition within LUA

["Grisha" <grisha@...>]

Hi, Dan

very easy: just export a function that creates an instance of your class

function myclass()
    local c = {}
    c.myfunc = function ()
        --do stuff
    end
    c.n = 10
    return c
end

host.RegisterClass(myclass)

sincerely yours,
Grisha
