Struggles in a graphics editor project

[Pospos]

i tried to make a graphics editor but i messed up somewhere.
The purpose is to write a text table 16x16 characters inside of it
with numbers to report inside of a text file, to then call them and draw them
any time using pixels of some colors.
the program isn't quite ready yet, but the purpose is simple.
The thing i would like is some help in writing this code and critiques
beacuse i struggle to make it correctly.
Maybe i'm too ambitious, but that would be awesome to create this little program.

Code: Select all

function graphic_write(a) -- write the graphics
writegraphic = io.open("graphlib/graph.lua", "w")
writegraphic:write(
	"graphic"a" = {}
	graphic"a"[1] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,} -- 0 corresponds to the red color.
	graphic"a"[2] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
	graphic"a"[3] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
	graphic"a"[4] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
	graphic"a"[5] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
	graphic"a"[6] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
	graphic"a"[7] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
	graphic"a"[8] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
	graphic"a"[9] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
   graphic"a"[10] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
   graphic"a"[11] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
   graphic"a"[12] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
   graphic"a"[13] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
   graphic"a"[14] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
   graphic"a"[15] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}
   graphic"a"[16] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,}")

end
function graphic_draw() -- call the graphics

	local line
	local colonne
	 for line=0, 16 do
	 for colonne=0, 16 do
	 	love.graphics.setColor(color[map[line+1][colonne+1]])
	 	love.graphics.rectangle("fill", colonne*16, line*16, 1, 1)
	 end
	end

end

You didn't put text concatenation marks.

You didn't put text concatenation marks.

IMO the issue is not that, instead it's the fact that he wanted to use the same string delimiters both inside the string he wanted to write out and for the delimiters themselves... or in other words, the two outermost "-s should be replaced by '-s or [[ ]].

like this?

but how i handle the ) thing.

Have you considered using a serialization library like bitser?

Code: Select all

bitser = require('bitser')

function newMap()
	local map = {}

	for line=1, 16 do
		map[line] = {}
		for colonne=1, 16 do
			map[line][colonne] = math.random(1, 4)
		end
	end

	return map
end

function loadMap()
	return bitser.loads(love.filesystem.read(filename))
end

function saveMap()
	love.filesystem.write(filename, bitser.dumps(map))
end

function love.load()

	filename = 'map.txt'
	color = {
		{255, 0 , 0},
		{255, 255 , 0},
		{0,  255, 0},
		{0, 255 , 255},
	}
	if love.filesystem.isFile(filename) then
		map = loadMap()
	else
		map = newMap()
	end
end


function love.keypressed(key)
	if key == 'n' then
		map = newMap()
	elseif key == 'l' then
		map = loadMap()
	elseif key == 's' then
		saveMap()
	end
end

function love.draw()

	for line=0, 15 do
		for colonne=0, 15 do
			print(line, colonne)
			love.graphics.setColor(color[map[line+1][colonne+1]])
			love.graphics.rectangle("fill", colonne*16, line*16, 16, 16)
		end
	end

end

No, more like this... though i must admit, i didn't test whether this worked or not:

also, do you have any idea of a lua function to read
file and store data inside of them?
i've taught about require, but i'm not sure.
