#3 I haven't got anywhere getting this to work :(

Seeing as only the player in my game will be using the FlyingVehicle however, with a 1st-person or near 3rd-person camera, a 3D sound's maybe a bit of an overkill.

Maybe I can just adjust FlyingVehicle.cc to use a 2D sound and attenuate the volume based on the FlyingVehicle's current speed (mRigid.linVelocity.len();).

#4 If your game is going to be multiplayer you might want to store your audio profile/description info on the server and not the client. Other than that your script looks fine. I don't have any problems with a flyingVehicles engine sound so I can only suggest the following:

- Try using a different wav sound
- Try using an ogg
- Don't see that it would make a difference but try moving your audio profiles/descriptions to the server.
- Try altering the length of your engine sound

#5 Hi Tim,

This one's just singleplayer; I tried initially having audio profiles/descriptions on the server and only actually put them on the client when I couldn't get them to work serverside.

At your suggestion I've played with the length of the engine sound to no avail; at the moment I'm using 2 seconds of 400Hz sine wave for testing. The other emitters in my missions also use wavs rendered by Sound Forge so I don't think that's it.

I'd rather not use my manually-attenuated 2D sound idea (above) if possible but I'm still not getting this working.

I can't find an all-inclusive FlyingVehicle demo in any of the resources on the topic. Just in case I'm missing something obvious could someone who's had success possibly outline the steps they've taken to get a working FlyingVehicle engine sound? (eg start with fresh starter.racing, implement a resource such as this, add audioprofiles, etc)

#6 As another thought, does anyone know a gotcha that would prevent this working if I was building from tutorial.base instead of starter.racing?

#7 Well I've done a helicopter resource which uses an engine sound and is based on the flyingVehicle class. It's not a step by step tutorial but you might find it useful.
