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()

Hi all,
I find myself repeating the same type of code over and over. Is
there an idiom for this type of thing?
self.spBackGround = CreateSprite()
local sp = self.spBackGround
sp:setSize( 10, 10 )
I am looking for something along the lines of:
local sp = self.spBackGround = CreateSprite()
sp:setSize( 10, 10 )
