how about you just answer his question instead of telling him where to post.

try

files = System.listDirectory()

for index, file in files do
print(file.name)
end

ooo, in the luaDevKit you'll go to the file i/o menu and click list files in current directory

Look at the file browser in the Lua snippets thread( bottom )... Always check there before asking

[Glynnder]

So theres an option- add menu... etc...

thanks that was helpfull however... i just reolized that the mp3 mod only plays mp3s from your lua programs directory

if i try and give it something like Mp3.load("ms0:/psp/music/myfile.mp3")

it will give me an error like this "error: index.lua:121: can't open sound file ms0:/psp/games/luaplayer20/applications/myapp/ms0:/psp/music/myfile.mp3")

its hardcoded to look for "myfile.mp3" inside your app folder toobad

so theres no way i can make it play from a list inside the psp/music folder



UNLESS someone with better skills then me takes a look at the mp3 mod code and removes that limitation

Alright ill help you with this and i can help more if youve got an IM oh and im tacticalpenguin but my real account got messed up from a vbplaza bug
anyways
you could do something like this in conjunction with something like my filebrowser:

if pad:circle() and not oldpad:circle() then
if string.lower(string.sub(f iles[s].name, -4)) == ".mp3" then --checks that the file is .mp3
Mp3.load(files[s+2].name)
System.sleep(30)
Mp3.play()
end
end

Just note that that is requiring the System.currentDirectory be the same as the dir the mo3 is in. If youd like, i made a little drop down bar with the psp/music folder contents in it and when you press circle it pays the MP3. If you need any help with file browser-related stuff, i can definitely hel

Yeah, that's what it i there for. Just contact the original maker to see if they want credit.

[Glynnder]

well, even if they don't they'll get it.

it'll add comments in e.g
--menu code by *author*--
