Adjusting speaker volume from script - NOT just on/off

[BlackMagic]

I want to adjust the volume of a speaker from script. I have a pan with "beef links" cooking on a stove. as the player takes them away (one by one) I want the "sizzle" sound to decrease. When all have been taken, I turn off the speaker from script. Works fine EXCEPT the volume is not changed. I tried $speaker_sausages.setKey("s_volume", 2);  as well as negative values, but it does not change. The starting value on the speaker is s_volume 10. What am I doing wrong?

You're right; changing the s_volume key during play seems to do nothing.

 

You can fake it by using multiple speakers though. Place one speaker for each beef link in the same place on the stove. Give one the volume you want when all the beef links are present, another the volume you want when one has been taken, and so on. Have only the loudest one playing on map start. Then when you take a chunk of meat, turn that speaker off and the next loudest one on, cycling through until all the meat is gone and the quietest speaker is off. You should be able to accomplish this fairly easily with two trigger_sequencers.

Actually, I worked it out by setting the speakers minDistance to 0.05, and then tweaked the maxDistance to shrink in the script. Thanks for responding thebigh. (does that mean The Big H?) have a virtual Fosters on me!

Huh, that's interesting that min and maxDistance are dynamically updated in-game but s_volume isn't.

Your method will have the issue that the sizzling will become inaudible at a shorter distance from the stove- if two steaks are audible ten meters away, realistically one steak should also be audible ten meters away but half as loud- but nobody will notice that if all the actual changes in volume will happen when you're standing right by the stove. And it does mean fewer speakers and less scripting.

Looking forward to seeing your mission and eating some of that beef!

And there is warm bread in the oven too! The Moor upstairs might be a bit upset..

$speaker_sausages.setKey("s_volume", 2);    That is a spawn time script function meaning what it does, only happens when a entity spawns, so would need to restart the mission for it to make effect, if you want to change something during gameplay, you need to call other functions like

/**
 * Fades the sound on this entity to a new level over a period of time.  Use SND_CHANNEL_ANY for all currently playing sounds.
 */
scriptEvent void		fadeSound(float channel, float newLevel, float fadeTime);

or

/**
 * Set the volume of the sound to play, must be issued before startSoundShader.
 */
scriptEvent void		setSoundVolume(float newLevel);
