--- This file is used to setup the map starting settings and the items players will start with

--- These are called factories because they return another function
-- use these as a simple methods of adding new items
-- they will do most of the work for you
-- ['item-name']=factory(params)

-- Use these to adjust for ticks ie game.tick < 5*minutes
local seconds, minutes, hours = 60, 3600, 216000

--- Use to make a split point for the number of items given based on time
-- ['stone-furnace']=cutoff_time(5*minutes,4,0) -- before 5 minutes give four items after 5 minutes give none

--- Use to make a split point for the number of items given based on amount made
-- ['firearm-magazine']=cutoff_amount_made(100,10,0) -- give 10 items until 100 items have been made

--- Same as above but will not give any items if x amount has been made of another item, useful for tiers
-- ['light-armor']=cutoff_amount_made_unless(5,0,1,'heavy-armor',5) -- give light armor once 5 have been made unless 5 heavy armor has been made
local function cutoff_amount_made_unless(amount,before,after,second_item,second_amount)

-- Use for mass production items where you want the amount to change based on the amount already made
-- ['iron-plate']=scale_amount_made(5*minutes,10,10) -- for first 5 minutes give 10 items then after apply a factor of 10

    Common values
    game.tick is the amount of time the game has been on for
    amount_made is the amount of that item which has been made
    items_made('item-name') will return the amount of any item made
    player is the player who just spawned
    hours, minutes, seconds are the number of ticks in each unit of time
