# Tiny level editor

Hello guys, today i want share to community my first and very tiny level editor
Code:

displayMode(FULLSCREEN)
-- Use this function to perform your initial setup
function setup()
lvl = {1,2,3,0,
0,2,0,0,
0,2,0,0}
pos = {}
local nrow = 0
for k,v in pairs(lvl) do
if math.fmod(k,4) == 0 then
nrow = nrow + 1
end
if v == 0 then
table.insert(pos,vec2(-200,-200))
else
table.insert(pos,vec2(WIDTH/4+(v)*100,HEIGHT/2-nrow*100))
end
end

end

-- This function gets called once every frame
function draw()
-- This sets a dark background color
background(40, 40, 50)
for k,v in pairs(pos) do
--rect(v.x,v.y,512/4,512/4)
sprite("Platformer Art:Crate",v.x,v.y,512/4,512/4)
end
strokeWidth(5)
end

function touched(t)

end

Little explaining :
You have table “lvl”, which store information, where is your ground
Table “pos” store converted numbers to coordinates from table “lvl”

In this code you can make 3x3 field, if you want make 4x4 or 5x5 (and so on) you must fill last column with 0 , so you 4x4 field
would be

lvl = {1,2,3,4,0,
1,2,3,4,0,
1,2,3,4,0}

And you must change number on this method to amount numbers in your table lvl , including column filled with zeros

math.fmod(k,4) == 0

How can you see on the top, i formatted form of lvl table . In my example code you would see T-map , so imagine this numbers are blocks.

P.s sorry for my bad explanation, if something is not clear for you, ask me in this thread or pm

Hello guys, i commended this thread , to not mess up forum, so im seek for your help: i have field and hero . And i want make algorithm which will make “walls” around field. How you can see below (hope images attached) there are my thoughts in adobe draw and In-Game view .

On sketch you can see “t” - its non walking place , on game screen it place with blue box on the top

I know the shortest solution its make my hero by phys.object and make walls, but it will decrease FPS and slow down my project. Maybe i can handle with setContext(), but i have no idea how to make it

I would simply test the x,y position of the hero, and not let him walk into the “non walking” tiles.

@ignatz thank you, i thought about that, but i guess it would be glitchy

@yojimbo2000 thank you alot, now i got it
