MrGreen wrote: ↑Fri Aug 02, 2019 1:53 pm Okay, thank you for your advise. I already worked on the structure this afternoon and deleted all unnecessary stuff. And by snack I mean the circle the snake can eat.

function love.draw()
    for j=1,31 do
        for i=1,31 do
        	love.graphics.rectangle('line',(i-1)*32,(j-1)*32,32,32)
	end
    end
end

love.graphics.setWidth(2)

Well figuring out things on your own is a good idea but you should also look at how other people solved the same problem. In programming is all about - "finding the best possible solution to a problem?" - so how would you know if your solution is the best unless you compare it with that of your peers.

MrGreen wrote: ↑Fri Aug 02, 2019 2:19 pm Okay, that is bothering me, too. Could you give me another tip for this problem?

	function love.update(dt)
		if love.keyboard.lastKeyPressed=='up' then
			-- your logic here
		end
		love.keyboard.lastKeyPressed=nil
	end

	function love.keypressed(key)
		love.keyboard.lastKeyPressed=key
	end

lovecc:setColor('red')

YoungNeer wrote: ↑Fri Aug 02, 2019 2:03 pm Plus you don't need to have a background image. You could basically just have a for loop and render rectangles of unit size (let's say 32x32 in this context) :- { and I recommend you change the window size to 992 from 1005 just for this to work well)

Code: Select all

function love.draw()
    for j=1,31 do
        for i=1,31 do
        	love.graphics.rectangle('line',(i-1)*32,(j-1)*32,32,32)
	end
    end
end

MrGreen wrote: ↑Fri Aug 02, 2019 2:32 pm That is a thing which I was unsure about. So it is faster than taking an image? I decided to leave the background away, but it would be interseting when it is faster to draw an image or using the graphics-function (I think it is a lot faster to load an image where all pixels are different than to make only 1x1 rectangles)

local position = {0,0} -- where the head of the snake is
local direction = {0,0} -- what direction it's going
local speed = 10 -- it moves this many pixels each time it moves

love.keypressed = function(k,s)
  if s == 'up' then
    direction[1] = love.keyboard.isScancodeDown('down') and direction[1] or 1.0
    direction[2] = 0.0 -- orthogonal movement
  elseif s == 'down' then
    direction[1] = love.keyboard.isScancodeDown('up') and direction[1] or -1.0
    direction[2] = 0.0 -- orthogonal movement
  elseif s == 'left' then
    direction[1] = 0.0 -- orthogonal movement
    direction[2] = love.keyboard.isScancodeDown('right') and direction[2] or -1.0
  elseif s == 'right' then
    direction[1] = 0.0 -- orthogonal movement
    direction[2] = love.keyboard.isScancodeDown('left') and direction[2] or 1.0
  end
end

local time = 0.0
love.update = function(dt)
  time = time + dt -- time is passing, dt is the time passed since the last love.update call.
  if time > 0.5 then -- move twice every second
    position[1] = position[1] + direction[1] * speed -- set the new horizontal position
    position[1] = position[1] + direction[1] * speed -- set the new vertical position
    time = time - 0.5 -- reset the timer so it moves continuously
  end
end

love.draw = function()
  love.graphics.rectangle('fill', position[1], position[2], 10, 10) -- draw the head of the snake as a 10x10 square.
end
