Global option Sound volume in the engine

[ArBuZ]

Hi!

I want to implement an option Sound and Music volume in my game. And Ive found that its not as simple as it should be

There is no any global parameter in the engine, only SetSourceVolume. But then I have to go through all my sources and set it's volume.

Have anyone done this before?

 

Thanks in advance.

I would try something like the following. First make groups of sounds and sound sources.

--load sound
music1	= LoadSound("abstract::music1.OGG")
music2	= LoadSound("abstract::music2.OGG")
sound1  = LoadSound("abstract::sound1.OGG")
sound2	= LoadSound("abstract::sound2.OGG")

-- create sources
source_music1 =CreateSource (music1)
source_music2 =CreateSource (music2)
source_sound1 =CreateSource (sound1)
source_sound2 =CreateSource (sound2)

--declare 2 sound variables
MusicVolume = 5
SoundVolume = 5

-- 2 functions for setting the volume
function SetVolumeOfMusic ()
  source_music1:SetVolume( MusicVolume )
  source_music2:SetVolume( MusicVolume )
end

function SetVolumeOfSound ()
  source_Sound1:SetVolume( SoundVolume )
  source_Sound2:SetVolume( SoundVolume )
end

It would be even better if you could add a source to a Sound group. This way you wouldn't even have to place all sources in to the function.

Your way would work for simple solutions. But in complex solutions with classes (C++) when for example Source is a member of class, things become more complicated and handling all sources of all objects in scene is very tricky.

Hey arbuz,

you could write the lights into an array and then loop throught all of them.

You can also use EmitSound if you want, because there you can set the volume directly =)

 

Hope it'll help you
