-- a little helper function to print centered text
function print_center(text, x, y, color)
    -- get the lenght of the text
    -- if you did not know, print returns the position of the last character
    -- so fi you print offscreen, starting from 0 you will get the exact lenght of the text
    local len = print(text, 0, 400, color)
    print(text, x-(len/2), y, color)

-- state machines might sound complicated, but when it comes down
-- they are just if statements that control how our code behaves.
-- based on certain conditions you can jump between "states"
-- and this can help you also organize stuff better, animate more freely, or
-- for example, let's use state machines to create a menu system for our game
function _init()
    -- we will start on the game logo scene
    -- and we will have the following:
    -- menu: to show a nice menu if you want
    -- gameplay: where the actual game code runs

-- create a table to hold your objects
coins ={}

--now you can add things into here by hand, but you can also make a functionnsonyou can call that point

function add_coin(xpos, ypos)
  -- now lets make a temporary local table to hold the coins atrributes, you want position mainly
  local coin = {
    x = xpos,

-- inside init have a collection called particles
-- this is where we will store each an every particles, so we can iterate
-- over them in the future (aka process them one by one)
particles = {}

-- adder function, you call this anytime you want to add a new particle
-- to the system. This will help us centralise every modification as this
-- function is the only thing that you will have to modifiy.
function add_particle(_x, _y, _sx, _sy, _lifetime, _color, _type)
    -- create a local temporary particle where we create the data

-- For this I whipped up my good ol’ reliable approach of having the following functions:
-- export the currently drawn map to the clipboard
-- I used this in copied .p8 files to draw levels,
-- run them and copy the given string into this main
-- file's map collection
function export_map()
    -- start with empty string
    local mapString = ""
    -- loop over the map tile by tile
    -- and append tile numbers by , after each other

-- Or if you don't want to bother with drawing each pickup with every tile aviable to you, you can make them "objects".

--For this, create an array, that will hold all our pickups:
pickupCollection = {}

-- and a function that you can call to add pickups.
-- we include a _type so later you can differentiate them
-- by checking the this. For ex: _type = 1 is a healing item, _type = 2 is a bomb etc...
function add_pickup(_xPosition, _yPosition, _type)
	-- we create a local variable to hold the item
