Selecting oldest object question

#1

I have a table where objects are created and I want to run some logic stuff on the objects in order of how they were created, but I don’t even know how to Google what I want to do. 

So basically I have a table like:

local table {}

numberOne[1] = “1.png”

numberTwo[2] = “1.png”

numberThree[3] = “1.png”

Then I randomly display the images with something like:

function getNumber()

   local number = display.newImage(table[math.random(1,3)])

end

And I do this on a timer:

tmr = timer.performWithDelay(2000,getNumber,3)

What I’m hoping to do is use logic with the number, (I know this is wrong but I think it will help explain it), basically I want to do something like:

if (number = 3) then

   number.isVisible = false

end

I want to run the logic on the numbers in the order they were created (oldest first). Like if the numbers two was the first number created, then run the ‘if statement’. I really don’t know how to make sure I’m not going to use the logic against all three items at once or the most recent one created. I’m not sure if I asked this right or even how to phrase what I want to do in Google. Any help would be much appreciated.

So you want to be able to loop through all of the images oldest to new and just check some stuff about each one?

What I’d be inclined to do is to convert your array to a structure, so each array entry is a table containing the filename, the display.newImage reference, the timerID and so on.
