Re: Assign idiom

[Michael Broughton <mbobowik@...>]

Use multiple returns...

function CreateSprite()
   ...
   return sp, sp
end

local sp
self.spBackGround, sp = CreateSprite()


Or...

function f(p)
   return p, p
end

local sp
self.spBackGround, sp = f(CreateSprite())



Or perhaps something a little different... Have each of your sprite's 
methods return its first argument...

self.spBackGround = CreateSprite()
local sp = self.spBackGround:setSize( 10, 10 ):doSomething()
sp:doSomethingElse()
