So I've added music to my game, and I'm tryin to do a volume control. For clarity purposes, this is what I'm trying to do:

I want the music volume to go up or down as you drag the bar. I know in the interface there's a section labeled "Command to run when value has changed". But I'm not sure how to go about coding the command to do what I'm trying to do. I don't want the sound file that's already playing to restart if possible. In other words, I need the value of the adjustable bar to correspond with music_volume

The variables I have are:
music_volume --- controls the volume of sounds
music --- the sound file playing to the player

You can update the volume of a sound without restarting it by applying the SOUND_UPDATE flag to its status variable:
client
    var tmp
        sound/music // The music currently playing

    proc
        // e.g. client.PlayMusic(sound('music.ogg'))
        PlayMusic(sound/Music)
            music = Music
            Music.status |= SOUND_STREAM
            src << Music

        SetMusicVolume(Volume)
            music.volume = Volume
            music.status |= SOUND_UPDATE
            src << music

        // You can also mute a sound while it still plays
        // with status SOUND_MUTE
        // or pause with status SOUND_PAUSE
        // (sending the sound again with just SOUND_UPDATE unpauses/unmutes)

    verb
        // The command to run when changed should be (without quotes):
        //   "volume-slider [[*]]"
        volume_slider(Volume as num)
            set hidden = TRUE
            SetMusicVolume(Volume)
