Re: Simple classes

[Jose Marin <jose_marin2@...>]

That´s good, but I need a more generic solution, because my game will has a lot of classes.

Using the syntax of one solution I´ve seen:


CActor = Class("Actor")

function CActor:update()
   print ("Actor:update")
end

--                Name      Base
CSoldier = Class("Soldier", Actor)

function CSoldier:update()
   self.base:update()
   print ("Soldier:update")
end


soldier1 = CSoldier:new()

soldier1:update()



I will investigate this more later tonight.

Thanks for the reply

Jose
