A question about music

[Keisser]

Greetings everyone.
I have music files in a folder and I want them to constantly play at background, so, when one ends, another one starts playing. Unfortunately, I don't see any possibility in Love2d to detect the end of sound file. Is it even possible?

If it's not looped, it stops playing at the end. As in, the playsate changes to "stopped". You can detect this and play the next track.

Well I created this code and it does not seem to work properly.

Code: Select all

----

local music_volume = 0.5
--local sound_volume = 1

----
music = love.audio.newSource("music/mus_"..math.random(11)..".mp3", "stream" )
----

if music:isPlaying( ) == false then
	math.randomseed( os.time() )
	math.random(); math.random(); math.random(); math.random(); math.random()
	music = love.audio.newSource("music/mus_"..math.random(11)..".mp3", "stream" )
	love.audio.play( music )
	music:setVolume(music_volume)
end

Music starts at the beginning of the game but as soon as it ends, nothing happens.

Simply put

Code: Select all

if music:isPlaying( ) == false then
	math.randomseed( os.time() )
	math.random(); math.random(); math.random(); math.random(); math.random()
	music = love.audio.newSource("music/mus_"..math.random(11)..".mp3", "stream" )
	love.audio.play( music )
	music:setVolume(music_volume)
end

into love.update()

People, people, no need to reinvent the wheel if you only want a track to loop from start to end, there's a method for that: Source:setLooping

Example:

Code: Select all

music = love.audio.newSource("music/mus_"..math.random(11)..".mp3", "stream" )
music:setLooping(true)

-- Then call music:play() somewhere in your code that's not the update function.

Edit: I seem to have misread the actual issue; this only loops one track. I will give an edited version of Andlac'syour code since it's bad to use the lua random generator when löve provides a better one.

Code: Select all

if not music:isPlaying( ) then
	music = love.audio.newSource("music/mus_"..love.math.random(11)..".mp3", "stream" )
	-- ^ or love.math.random(1,11) if you lack a mus_0.mp3
	music:setVolume(music_volume)
	love.audio.play( music )
end

I put the code into love_update() and nothing is playing now. This neither works when I have it in a separate .lua file nor in main.lua.

Code: Select all

	math.randomseed( os.time() )
	math.random(); math.random(); math.random(); math.random(); math.random()

lmao

I put the code into love_update() and nothing is playing now. This neither works when I have it in a separate .lua file nor in main.lua.

This would be the perfect time to post the exact code that shows the issue that can be run with a minimum amount of effort for anyone else trying to reproduce it.

Yeesh, that guy's a grump allright.

The proper spelling is "love.update". The "update" function is in the table "love". Make sure you never define another "love.update" function, it'll overwrite the last one.

Wut? Nah. A grumpy response would have been a link to How To Ask Questions The Smart Way without further comment. Also, please don't assume my gender.
