Adding more options for volume #1180

Hey!

What do you think about adding a new setting to audio for master volume.
Many games have three (or sometimes more) volume sliders: master, music, sound.
The volume for playing audio is then calculated by:
soundVolumeForPlay = master * sound
musicVolumeForPlay = master * music
What do you think about adding the possibility to play a sound with a different volume eg. adding a new optional parameter to the methods for playing a sound or music.
In my game I have certain sounds for ambience which should be played with lower volume.
What I am currently doing with FXGL is: 1. Lower sound volume, 2. Play sound, 3. Raise sound volume.

Hi,

As far as I can remember, existing volume for sounds and music are the master volume for their respective types.
Each sound / music object can be applied with its own volume. Try:

Sound sound = getAssetLoader().loadSound(...);
sound.setXXXX

Let me know if this works.

Thank you for your answers.

Yes, but I think about a separate volume setting which effects both types simultaneously. In my game I call the third setting the main volume which exists in addition to sound and music and will be used as a multiplier (as described in my original post).
My Eclipse does not get the connection to the class Audio and therefore does not find the methods. Do you have any ideas what I am doing wrong?

Given it is relatively easy to create a new property to bind the two existing ones, I am not sure whether it is needed to be on the engine side.
That's a good point. It seems the implementation is hidden from public API. This might have been necessary to hide cross-platform support (particularly on mobile), but I don't see why we couldn't open access to getAudio(). From the list you will note the method is actually there, just hidden in $fxgl_core. I'm happy to turn this into an issue, so we can track it and fix it eventually.

Thank you, I am ok with that.
I would be glad if you could open an access to audio.

@nicymike @chengenzhao

This is now public:

var sound = getAssetLoader().loadSound("file.wav");
var audio = sound.getAudio();

getAudioPlayer().playSound(sound);

// by default audio player will manage the volume, but we can manually override
audio.setVolume(volume);

It works
but there is a small problem
developers have to play sound/music first
then set the volume
it doesnt work if the order is reversed
like

audio.setVolume(volume); 
getAudioPlayer().playSound(sound); // it won't work
