love2d - file doesnt exist but it does

Question

I am making a platformer game in Love2D, and I created my own lua script that processes level files.
I used dofile in levelprocessor.lua and in main.lua, i require() it and the module sucessfully loads.

However, when I try to process the level (level1.lua), it says the file isn't found. But the file exists in the same directory as levelprocessor.lua and main.lua.

Here is my code:

levelprocesser.lua:

local blocks = {
["1"]=(love.graphics.newImage("blocks/grassdirt/grass.png")) -- singular piece of grass
}

local mod={
}

function mod.placeBlock(blockID, posx, posy) 
position = {x=posx*32,y=posy*32}; --blocks are 16x16 and drawn 32x32, and x and y here are in block coordinates, 
-- so a block with ID 1, posx 1, and posy=1, would be a grass block 32 pixels x and 32 pixels y.
for key, value in ipairs(blocks) do
-- glad roblox and that book called Beginning Lua Programming made me understand generic for loops
if key == blockID then 
love.graphics.draw(key, position.x, position.y, 2,2);
else
error("Error in processing level file")
end
end
end

function mod.processFile(fileDir) 
assert(type(fileDir) == "string", "error in function processFile in file levelprocessor.lua: argument 1 must be ")
local level = dofile(fileDir);
for i,v in ipairs(level) do
placeBlock(v.blockID, v.posx, v.posy)
end
end
return mod

main.lua:

levelprocessor = require "levelprocessor" -- remember kids, do require without file extension
function love.load()
healthbar = love.graphics.newImage("ui/Untitled.png")
good_health = love.graphics.newQuad(0, 0, 100, 36, healthbar:getDimensions())
caution_health = love.graphics.newQuad(100,36,102, 36, healthbar:getDimensions())
warning_health = love.graphics.newQuad(102,36,204,36,healthbar:getDimensions())
grass_top_singular = love.graphics.newImage("blocks/grassdirt/grass.png")
 end

function love.draw()
    love.graphics.draw(grass_top_singular, 0,568,0,2,2); -- 600-32=558... mental math, so im not sure if it is truly correct
    levelprocessor.processFile("level1.lua")
end

The error itself is:

cannot open level1.lua: No such file or directory

Traceback

[C]: in function 'dofile'
levelprocessor.lua:22: in function 'processFile'
main.lua:12 in function 'draw'
[C]: in function 'xpcall'

require searches in configured paths. dofile doesn't. dofile uses the processes working directory. — Etan Reisner

Can't reproduce this. Minimal code I tried: In main.lua: function love.load() dofile "foo.lua" dofile "foo/bar.lua" end; in foo.lua: print "foo works"; in foo/bar.lua: print "foo/bar works"; running this will print "foo works" and "foobar works". What version of love2d are you on? — nobody

Ah, yes – running from a different directory means it fails. — nobody

Replace

dofile( f )

by

assert( love.filesystem.load( f ) )( )

love.filesystem.* will look in the source directory (and a few other places), not in the working directory.
