Hi guys, where am I going wrong here?

I'm trying to create two instances of "Ball" and print each ball's size afterwards. The output now is "big", "big", so the "size" variable is overwritten when I create the second instance.

-- Ball.lua
 
Ball = Core.class() 
 
local size
 
function Ball:init( _size )
	size = _size
end
 
function Ball:getSize()
	return size
end

-- Main.lua
 
local balls = {}
 
local ball1 = Ball.new( "small" )
table.insert( balls, ball1 )
 
local ball2 = Ball.new( "big" )
table.insert( balls, ball2 )
 
for i=1, #balls do
	print( balls[i]:getSize() )
end

Isn't it marvellous how a public post sharpens the mind? This change to Ball.lua works:

-- Ball.lua
 
Ball = Core.class() 
 
function Ball:init( _size )
	self.size = _size
end
 
function Ball:getSize()
	return self.size
end

@totebo: You beat me to it. I had just posted exactly the same thing.
But because it is impossible to delete a posy I edited it instead lol

Seems such a shame to " delete a posy"
