Far-off exploding sound.

[Feared_1]

If you're fairly far away from a ship explosion in the game, you can hear the sound come roaring toward you, then away from you.

I just wanted to know what that is, and how you determine whether it is there or not.

[Steeveeo]

I've always wondered how the engine controls that sound, but its supposedly the whistling of either debris or the ejection (I believe is the latter). IIRC the sound is ordin_a.wav

EDIT:

The tag is either:

BailSound = "<name>.wav"

or

ExplodeSound = "<name>.wav"

check both.

[TheJamsh]

yeh its the like bail thingy, probably the pilot shooting into the air at 500 miles an hour or so...

one thing that is hilarious, set game.cheat bztnt turned on, then keep pressing the C key for the jetpack, do that like 20 times and i waited nearly 30 minutes it still didnt touch the ground...

to think that the jetpack flame emits at soemthing like 0.001 a second, and i could see clear centimetre gaps between them on screen lmao!

off topic but random

OK!

While we're already on a tangent. The thing with the pitch of the sound changing is called the Doppler effect. In real life it has something to do with the speed of sound -- and because the speed of sound is finite and slow (compared to, say, the speed of light) it is possible for objects to move faster than the speed of sound.

When an object is moving towards you, its sound will be higher pitched because the sound waves that it emits are compressed. When the object is moving away from you, the sound will be lower pitched because the sound waves it emits are spaced out wider. An example of this is right before/after a semi passes by you, or a plane flies over you.

I like how BZ2 tries to replicate that effect.

You can adjust these settings in Gameprefs.ini to adjust where sounds begin and end and how much Doppler you hear:


// Distance ranges for various classes. These values must be between
// 2.0f and 250.0f. The values here seem to work well.
vehicleMinDist = 50.0
vehicleMaxDist = 250.0
explosionMinDist = 50.0f
explosionMaxDist = 250.0f
weaponMinDist = 50.0f
weaponMaxDist = 250.0f
ordnanceMinDist = 50.0f
ordnanceMaxDist = 250.0f


// Various 3D setup flags. These are the defaults, I believe, and
// ought to work. See the DirectX SDK docs for info on what they are.

// D3D listener params
flDistanceFactor= 1.0f
flRolloffFactor = 0.5f
//flDopplerFactor = 1.0f
flDopplerFactor = 7.0f

It can sound really odd if your unit talk as much as mine do...nasty bigmouth squids things!

[Feared_1]

Yes I knew about the doppler effect

I just wanted to know more about that particular sound in BZ2.

Is there any way to make that sound appear very faint from across a map?

I like how BZ2 tries to replicate that effect.

DirectSound 3D does that more or less for free. It's just a matter of telling it position & velocity of all sounds, plus position & velocity of the 'listener'.

Is there any way to make that sound appear very faint from across a map?

I could have sworn you've asked this before, and you didn't like the answer given: DLL. Have a nice day.

Light does it to, it's called red shifting. As the light waves expand (or contract) the color changes. Gee, can we use that in bz2?

No, I don't believe I have...

Thanks though.

Things in BZ2 go *far* too slow for any light-shifting to take place however.  Any non-trace weapons (beams are trace weapons for example, stabbers are not) in BZ2 go far far too slow (I doubt any even reach 500mph, BZ2 would probably turn that into a pure trace anyway at that speed since the scales are so small), you would probably have to reach a few hundred thousand mph for it to become noticble enough to think about emulating.  Not to mention that you would probably need shader support for it to be fast.



I remember someone asking that sound question too at one point as well, no clue who...

[Red Devil]

Speaking of far off sounds, if I, being a man, say something in the woods here, am I still wrong?

Probably, if what you say makes as much sense as the above doesn't.
