corona sdk. Just starting with corona and lua and wondering about classes/instances
===

I've just started learning corona and lua, my 1st project is to make a little dice game and Ive just started it! heres the dice object...


		--declare table + metatable

		local dice = {}

		local dice_mt = {__index = dice}


		--CONSTRUCTOR 

		function dice.new(ypos, xpos) 

		local newdice = {xpos = xpos, ypos = ypos,dicetext = display.newText("X", 50*xpos , 50*ypos , nil, 50)} 

		--dicetext = display.newText(facevalue, 50*xpos , 50*ypos , nil, 50)

		return setmetatable(newdice, dice_mt) 
		end

		--rolldice function

		function dice:rolldice()

		self.dicetext.text = math.random(0,6) 

		end

		return dice

the game is to have a grid of 25 dice which can be rolled (with rolldice function above)
Heres my main.lua 


		display.setStatusBar(display.HiddenStatusBar)

		local diceclass = require ("dice")

		for i = 1, 5, 1 do

		local die = diceclass.new(i,i)

		i = i+1

		end

		die:rolldice()


I'm trying to generate the grid of dice programatically (atm I am just generating 5 dice(just text) in a diagonal line. Thats fine so far but my problem is running the rolldice function. It works when there is only 1 dice but not when there is more.
I'm guessing the problem is that I have all these instances of the class with the same name.. Is there a way to give them different names programmatically as I create them in my for loop? Or is there some better way of doing this? Thanks!
