Re-plays a sound effect if triggered.  If in state ''TriggerToggled'', the sound is turned off if triggered, and turned on, etc.. when triggered again.  In the ''OnWhileTriggered'' state, the instigator must stay within the trigger's radius for the sound effect to continue playing. ''bInitiallyOn'' determines if the sound is playing from the start, and does not apply in the OnWhileTriggered state.  A variance can also be set for the timing, so that the replay time can seem more 'real'.

Advanced -> bStatic IS the problem with the TriggeredAmbientSound.  On and above that, the TAS was likely coded up rather quickly for a specific purpose and therefor leaves lots to be desired.
 
−
 
−
For you sounding pleasure, however, I coded up a much better (if I do say so myself :) ) TAS.  Here's a list of its new properties and one other parent property setting worth mentioning:
 
−
 
−
TrigAmbSound properties:
 
−
* var() sound StartSound;
 
−
* var() sound AmbSound;
 
−
* var() sound StopSound;
 
−
* var() bool  bInitiallyOn;
 
−
* var() float AmbDuration;
 
−
* Object/InitialState  TriggerToggle or TriggerControl (latter is default)
 
−
 
−
"StartSound" is where you can optionally place a one-shot sound.  This will play when the TAS is triggered.  Thereafter, if you specified an "AmbSound" (preferrably a looping sound), it will then play until you untrigger.  Once untriggered, if you specified a "StopSound", that will play to finish things up.
 
−
 
−
"bInitially" should only be set to True if you set Object/InitialState = TriggleToggle.  When doing this, the "StartSound" is bypassed and the process proceeds to the "AmbSound"...if any was specified.
 
−
 
−
If you set "AmbDuration" to anything other than it's default 0.0, the looping ambient sound specified in "AmbSound" will only play for the duration specified.  Thereafter, things will work as normal...i.e. you'll still get the "StopSound" when untriggering.

If you want the script, get it here: http://www.gentekcom.com/~diinc/UTMaps/TrigAmbSound.u
 
−
 
−
In UEd, You'll find it under KeyPoint (where you'd expect).  Open up the script and look at it...its rediculously simple.  Now, forgive me for being a smartass, but isn't THIS what you'd expect a TriggeredAmbientSound to do in the first place?

'''Tarquin:''' I tried a search of my UT folder for anything with the name "TrigAmbSound" and found this in both a map called DM-2001][ by Wayne Young (AKA Slartybartfast) and wdy_mods.U (whatever that is!) The 'OnWhileTriggered' state sounds like it corresponds to 'TriggerControl' described above. I don't know if it's coincidence that it uses the same name, or if it's an earlier version. If anyone feels like contacting this guy and asking him if we can alter his script & improve it, his website is http://www.ganimede.demon.co.uk/ (and he works for nVidia).

'''SuperApe:''' The bStatic problem?  I have a thought about this, although I'm not a UT person.  The bStatic problem could be solved with a special Trigger, like the VolumeTrigger is able to toggle bStatic Volumes.  The custom Trigger function can simply search for TrigAmbSound actors with the matching Tag and call <u>the TrigAmbSound's</u> Trigger function.

UT :: Actor >> Keypoint (UT) >> TriggeredAmbientSound

Re-plays a sound effect if triggered. If in state TriggerToggled, the sound is turned off if triggered, and turned on, etc.. when triggered again. In the OnWhileTriggered state, the instigator must stay within the trigger's radius for the sound effect to continue playing. bInitiallyOn determines if the sound is playing from the start, and does not apply in the OnWhileTriggered state. A variance can also be set for the timing, so that the replay time can seem more 'real'.

Properties[edit]

TriggeredAmbientSound[edit]

bool bInitiallyOn
Play sound on start up.
sound AmbSound
Sound to play.
float rePlayTime
After this time in seconds has passed, the sound is replayed from the beginning.
float rePlayVariance
rePlayTime varies until ±rePlayVariance seconds randomly.
var() bool bPlayOnceOnly
AmbSound is played once only.

Object > InitialState[edit]

TriggerToggled
Toggles AmbSound on/off.
OnWhileTriggered
Sound is played only as along as the instigator stays within the trigger's radius.
None
Actor does nothing (except if bInitiallyOn==True).

Remarks[edit]

  • If rePlayTime and rePlayVariance are both zero, no sound will be played.
  • One of the Great Mysteries of Unreal I and UT: how to get this to work...? It seems problem #1 is Advanced -> bStatic needs to be set to false. However, there are reports that this still doesn't fix it. Several coders have made their own versions, see Discussion page
