getting the length of a source and some more questions

[Doctory]

how would i get the length of a source? i need it because im making a music player
i have all my music in a folder, how would i make a source for each and everyone of them without actually knowing the name of the file?
and how would i get the extension of a file, ex .mp3?

AFAIK, you can only get the length of [wiki]SoundData[/wiki], so you would do something like this:

Code: Select all

local sd = love.sound.newSoundData(sound_filename)
local length = sd:getSampleCount() / sd:getSampleRate()
local source = love.audio.newSource(sd)

how would i make a source for each and everyone of them without actually knowing the name of the file?

With [wiki]love.filesystem.getDirectoryItems[/wiki].

and how would i get the extension of a file, ex .mp3?

Something like:

Code: Select all

local extension = filename:sub((filename:find(".", 1, true))) -- parentheses important

I'll add that there was a :getDuration() function added in 0.9.0 for SoundData just for this.

Code: Select all

local length = sd:getDuration()
