Director and allocation/deallocation

Director Class
#1

Hi there. I have something to ask about deallocation. Before the questions, let’s take a look at two files:

  • first of them - showandanim.lua
module(..., package.seeall);  
  
function showAndAnim(x, y)  
 local grp = display.newGroup();  
 local img = display.newImage(grp, "star.png");  
 img.alpha = 0;  
 local twn;  
  
 function grp:fadeIn()  
 local function fadeOut()  
 twn = transition.to(img, {time = 500, alpha = 0.3, onComplete = fadeIn};  
 end;  
 twn = transition.to(img, {time = 500, alpha = 0.7, onComplete = fadeOut};  
 end;  
  
 return grp;  
end;
  • second one - scene01.lua - a director scene
module(..., package.seeall);  
  
function new()  
 local SaA = require("showandanim");  
 local tmr;  
  
 local grpScene01 = display.newGroup();  
 local grpShowAndAnim = SaA.showAndAnim(  
 display.contentWidth / 2, display.contentHeight / 2);  
 grpScene01:insert(grpShowAndAnim);  
 grpShowAndAnim:fadeIn();  
  
 trm = timer.performWithDelay(5000, function() director::changeScene("scene02"); end, 1);  
  
 function unloadMe()  
 if (trm) then timer.cancel(trm); trm = nil; end;  
 end;  
  
 return grpScene01;  
end;

As I could see, when the director loads the scene02, it free the grpScene01 and its childrens, in this example grpShowAndAnim.

My question is: what happens to img and twn (in showandanim.lua) and SaA (in scene01.lua)? I have to deallocate them?

I’m really confused about this scenario. Please, someone could help-me?
