---- structure
------------------------------------------------------------------------
-- each love program must have 2 files: main.lua and conf.lua

-----------------------------------
-- conf.lua
-----------------------------------
-- used for setting various settings.
-- the only requirement is that it must have the love.conf function
-- you can omit lines in the function that you don't need

function love.conf(t)

-----------------------------------
-- main.lua
-----------------------------------
-- this is the main file that runs the game

-- love.load is run one time when the game starts
-- for setting constants and global variables
function love.load()
end

-- love.update is run every frame
-- for updating game logic
function love.update()
end

-- love.draw is run every frame after love.update
-- for drawing the game's elements
function love.draw()
end


------------------------------------------------------------------------
---- drawing
------------------------------------------------------------------------
-- draws a rectangle - (outline/fill, x, y, width, height)
love.graphics.rectangle('fill', 0, 0, 10, 10)

-- draws a circle - (outline/fill, x, y, radius)
love.graphics.circle('fill', 0, 0, 10)

-- prints text - (text, x, y)
love.graphics.print('Hello, world!', 0, 0)


------------------------------------------------------------------------
---- input
------------------------------------------------------------------------
-- returns whether a key is down - (key)
love.keyboard.isDown('a')


------------------------------------------------------------------------
---- random
------------------------------------------------------------------------
-- returns a random number - (bottom range (included), top range (not included))
love.math.random(10, 100)
