Sound callback (text and sound sync) (SOLVED)

Questions
#21

nope, only make the table with timing of sounds and use the timer to catch complete event.

#22

:frowning: crap

#23

Is there a way to handle the volume/gain?

#24

Yeah use openal extention for sync text and sound.

This my code:

in on_message receieve message from text source and start sound:

                        local res = resource.load("/Voices/"..self.currentSoundId..".wav")			
			self.soundSource = openal.new_source(res)
			if self.soundSource then
				self.soundSource.x, self.soundSource.y = 0, 0
				self.soundSource.is_looping = false
				self.soundSource:play()
    		end

in on_update wait sound stop state. If sound stop - send callback message to text source.

if self.soundSource then			
			local soundState = self.soundSource.state
			if soundState == "stopped" then
					self.soundSource:stop()			
					msg.post("#","SoundStopPlay",{soundId = self.currentSoundId})											
			end	
		end

I make it on start, but now we hve openal extenstion and absent problem.

yep, openal is great! But there is one another problem - build size. If .wav files used instead .ogg for music for example.

#27

For music you can use standart sound object and ogg.

#28

of course, but if you want sequence of music (long level. etc,) you need to known when music file is done :slight_smile:
