Using dofile() ?

[Wombat]

Hi community,

is it possible to use dofile() to load AND run .lua files in LUA, or is there another possibility to load and run lua files?

Thanks in advance

Yes, but depending on what you want require is better.

is it possible that i have to give the full path, when i want to load a data with dofile().

For me, dofile("file.lua") doesn´t work, it says: "no such file or directory".

Here´s my code:

Code: Select all

function load.love()
love.graphics.setMode(800, 600, false, false, 0)
end

function love.update(dt)

if love.keyboard.isDown("a") then
dofile("main2.lua")
end

end

dofile("main2.lua")
end

end

running a file every time a key is pressed is a bad idea. Have the file return a function, then require the file and run iits function on key press.

Code: Select all

local importedfunc = require "myfile"

importedfunc()

Oh yeah, you shouldn't use dofile().

While require is usually what you need, in exceptional cases you will want to use love.filesystem.load, like this:

Code: Select all

local func = love.filesystem.load("somefile.lua")
if func then -- no syntax errors
    func()
end

I did like you´ve said but it don´t work. Nothing happens .

That should work. Where are the files placed? If you're running a folder, the file has to be either in the folder or in the write directory. If you're running a .love-file, it has to be inside the .love file or in the write directory.

[Wombat]

the file is in the write directory, where the main.lua is, too.

But finally it doesn´t work.

Sorry for getting on your nervs

Time for a .love then (see the red box above for details).

I find that placing main.lua in the write directory doesn't work for me when I run it as a folder. Why would you want to place main.lua there?
