return multiple class variables

MoKaLux

I don't understand why this doesn't work

TextIconX = Core.class(Sprite)   function TextIconX:init(xparams) local params = xparams or {} params.tex = xparams.tex or "life.png" params.text = xparams.text or "xxx" -- local ico = Bitmap.new(Texture.new(params.tex)) local tf = TextField.new(nil, params.text) tf:setPosition(ico:getX(), ico:getY()) self:addChild(ico) self:addChild(tf) -- return ico, tf end

Then in another class I call:

local ico, tf = TextIconX.new( { tex="life.png", text=0 } ) print(ico, tf) -- *** table: 032F9230 nil ***

Why tf is nil please ???

i guess ".new" is somewhat special and automatically returns an object of that class.
you can try calling ico,tf=TextIconX:init(...) instead of ico,tf=TextIconX.new(...)
but it would be less confusing if you'd name your function something else, like
TextIconX:generate(xparams) and then call it like ico,tf=TextIconX:generate(...)

thank you keszegh for your help.

I think you are right: ".new" is somewhat special and automatically returns an object of that class

I tried your solutions but cannot make it work

I am a bit surprised as it seems I did it many times before

EDIT: ok I found some code I did before and that worked calling "normal" functions, not Class.new() nor Class:init()

Thank you

BTW new is defined by gideros as part of the Core.class() call. See how it works here: https://github.com/gideros/gideros/blob/master/luabinding/property.lua

What can I say asking the same question over and over again

Thank you all for the help .
