Worked like a charm! Thank you very much, I’ve been scratching my head over this for hours!
The code looks like this now:
local function draw_squares(self, pos, range)
for i, v in ipairs(self.map_state) do
local in_range = math.abs(v.pos.x-pos.x)+math.abs(v.pos.y-pos.y) <= range * 48
if in_range and not v.occupied then
square_factory(self, v.pos, self.light_blue)
end
end
end
And the end result!
