Point Entity

The ambient_generic allows you to play a specific sound.

Attributes

Name (targetname) - Property used to identify entities.
WAV name (message) - This is the path/filename of the .wav file (note the forward-slash).
Volume (health) - Volume of the sound. Range: 0-10.
Dynamic Presets (preset) - Various effects that can be applied to the sound:

<TL>
0 = None 
1 = Huge Machine 
2 = Big Machine 
3 = Machine 
4 = Slow Fade in 
5 = Fade in 
6 = Quick Fade in 
7 = Slow Pulse 
8 = Pulse 
9 = Quick pulse 
<TC>
10 = Slow Oscillator 
11 = Oscillator 
12 = Quick Oscillator 
13 = Grunge pitch 
14 = Very low pitch 
15 = Low pitch 
16 = High pitch 
17 = Very high pitch 
18 = Screaming pitch 
19 = Oscillate spinup/down 
<TC>
20 = Pulse spinup/down 
21 = Random pitch 
22 = Random pitch fast 
23 = Incremental Spinup 
24 = Alien 
25 = Bizzare 
26 = Planet X 
27 = Haunted 
</TL>

Start volume (volstart)
Fade-in time (fadein) - Time taken for the sound to fade in. Range: 0-100
Fade-out time (fadeout) - Time taken for the sound to fade out, if not looped. Range: 0-100
Pitch (pitch) - 100 is normal, > 100 higher, < 100 lower.
Start pitch (pitchstart)
Spin-up time (spinup) - Range: 0-100
spin-down time (spindown) - Range: 0-100
LFO type (lfotype) - Values: 0=off,1=sqr,2=tri,3=rnd
LFO rate (lforate) - Range: 0-1000
LFO mod pitch (lfomodpitch) - Range: 0-100
LFO modvol (lfomodvol) - Range: 0-100
Incremental spin-up count (cspinup)

Flags

Play Everywhere (1) - Sound will be heard in the entire level.
Small Radius (2) - Sound range is about 800 units at max volume.
Medium Radius (4) - Sound range is about 1250 units at max volume.
Large Radius (8) - Sound range is about 2000 units at max volume.
Start Silent (16) - Checking this means the entity must be triggered to work.
Not Toggled (32) - Older FGDs show this as Not Looped. Specifies that the sound is to be played only once. With this flag checked, each time the entity is triggered it will play once. If it is not checked, triggering it will cause the sound to alternate between on and off.

Notes

From WorldCraft 2.1 Help: "To play a wav through the streaming code (for very large, one-shot wavs) use * in front of the name. For instance, ambienc/*speak2.wav would stream speak2.wav. Streaming sounds are loaded in segments from the disk, played, and flushed from memory."

"To play any sentence from sentences.txt, replace the path/filename.wav with ! followed

by the sentence name. For instance, !NA1 plays the sentence
named NA1."

"All the keyvalues from volstart to cspinup are various pitch, volume, and low frequency pitch

oscillation settings that are overridden by the dynamic preset setting. In general, don't use these. The incremental spin-up count may be used as follows: each time the ambient
is triggered, its pitch will rise from 'start pitch' to 'pitch' by this many increments. So, a setting of '3' means that the pitch of the ambient will rise from 'start pitch' to 'pitch' in three presses (ie: three triggers)."
