You will need the ambient_generic and the trigger_multiple entities
for this tutorial. Now often in your maps you need some funky
sounds, sometimes you might want to have sounds continually playing,
or sometimes you want sounds triggered off when you go near something.
Making a sound play by triggering it
firstly, place in a trigger. Now to do this, find where you want
to trigger the sound in your map, and simply put in block using
only the "aaa" texture. Now below we can see a machineeeee
(fig 1.0). Now want I want to happen is the "horror"
sound to come on when you go near it, so I need a "aaa"
block around it.
now place in the "aaa" block (fig1.1)
select your "aaa" block and tie it to the entity of
"trigger_multiple". Now there's a few properties in
here to fill in, however you only need to worry about the following:
Put in a target name, for this tut put in horror_sound1
Delay before reset: 10 (this is the time it takes to reset once
you have set off the trigger, higher the value the longer it will
take before it can be activated again)
thats it for our trigger, there's no need to tick any of the "flags"
in the trigger. Moving on, put in a ambient_generic where you
want, ive placed it above the area where I want the sound. Now
in the properties of the ambient generic we need the following:
Wave Name: ambience/the_horror1.wav (now since im making this
tut in halflife, it searches the pak file for sounds, if your
making a map for say dod, then you would browse to the sounds
folder and select an item, ive had to type it in manually for
halflife to where the sound is in the pak file)
Volume: 10 - well how loud it is, obvious stuff
Start volume 100, how loud it is when it starts, 100% I believe.
Start pitch 100, same as before
can leave everything else in there, its that simple, but you dont
need to change the flags, now ive ticked "medium radius"
obviously this is how far away the sound can be heard. and ive
ticked "start silent" otherwise it would maybe trigger
when you join the map. So leave everything else.
thats that, should work fine, and you can do this for any triggering
you might need, this is what's used for lots of maps, you dont
need to have the trigger anywhere special as well, I mean some
maps just trigger off an aeroplane sound when you are walking
along, so they place the trigger where they know people are going
to walk past/ along etc.
Having a continuous sound
you want a sound playing constantly throughout the map, well place
in an ambient generic, and check out its properties
indust_1 is what I called mine
Wave name: ambience/industrial3.wav was mine
Start Volume 100
thats all you need to do, then change the flags to play everywhere.
The wav will then play constantly throughout your map. If you
want it to just play once every spawn or something, tick the "is
not looped box"
