A Gist showing the basics of how to write a system that returns a local module in Lua/LOVE

main.lua

local player = require 'player'

function love.load()
  player.new(10, 10, 50, 50, 'Chandler Bing', 100)
end

function love.update(dt)
  player.update(dt)
end

function love.draw()
  player.draw()
end

function love.quit()
  love.event.quit()
end

player.lua

local player = {}

function player.new(x, y, w, h, name, gold)
  local p = { x = x, y = y, w = w, h = h, name = name, gold = gold }
  
  table.insert(player, p)
end

function player.update(dt)
  for i,v in ipairs(player) do
    -- Update your player here
  end
end

function player.draw()
  for i,v in ipairs(player) do
    -- Draw your player here
  end
end

-- any other function for the player should follow a similar format,
-- such that they all begin with "player." and contain a "for i,v in ipairs(player)" loop

return player
