Trying to use a loop to create graphical elements and what I gather is I need more context then just g: since it was be the loop's self in this case and not the functions? but I can not quite figure out what that context would be. Tried everything I can think of and did a fair amount of searching for an answer but I do not quite get lua's implementation of OOP and not completely sure I have it's scope and inheritance down, mostly I am just confusing myself at this point and blindly trying any solution I can think of. Simple example of what I am trying to do:

function boxes.paint(g)
   for i = 1, 8 do
      for j = 1, 8 do
         g:set_color(table.unpack(self.bg[i][j]))
         g:fill_rect(i*25, j*25, 25, 25)
      end
   end
end

Edit: Related question, is it possible to have each of those rectangles end up in their own layer?

@oid I think you made a small typo, it should say boxes:paint instead of boxes.paint. Also make sure you define 'self.bg' (don't click it, not a link) somewhere.

And yeah, you can put them on different layers too:

function boxes:paint(g)
         g:set_color(table.unpack(self.bg[i][j]))
         g:fill_rect(0, 0, 25, 25)
end

function boxes:paint_layer_2(g)
         g:set_color(table.unpack(self.bg[i][j]))
         g:fill_rect(25, 0, 25, 25)
end

function boxes:in_1_repaint1()
    self:repaint(1) -- repaints layer 1
end

function boxes:in_1_repaint2()
  self:repaint(2) -- repaints layer 2
end

But it'd be more tricky to do that using a single loop. Might still be possible with some lua tricks though

lol, not sure how that period snuck in but that fixed the problem. Now I just need to figure out how to automate doing each cell as its own layer but I think I can manage that now. Thanks.
