Hey there,

I am using the SoundPlay function to play footsteps sounds for a horde of npc's moving around...


I am using the following function:
SoundPlay("../Data/Sound/footsteps/grass/step1.wav",pos(),0.5,0.5);

I am also using:
Listener.pos(wData.Player->pos());
Listener.orn(wData.Player->lookDir());
Listener.update();

To update the listener position... the 3d positioning appears to be working correectly...

However, there is a constant "fluttering" type of sound playing at a low volume.... and at no point does the sound stop completely...

Ie: no matter how far i move from the group of npc's... the sounds is always there..

Is there a limit to the number of 3d sound that can be played? Am I doing anything incorrectly using this approach?

Thanks!

Hi,

Currently the 3D sounds don't fade out completely,

Please check this DirectX documentation on the sound volumes http://msdn.microsoft.com/en-us/library/...S.85).aspx

the parameter of 'range' in EE stands for 'minimum distance' in DirectX

If you'd like the sounds to don't play at all at long ranges,
you can add a simple 'if'
if(distance of the sound from the listener <= 100 ) // meters
{
SoundPlay(..)
}

I'll add a method for accessing the current Listener position in the next engine version

Great - that explains alot... using the distance filter stopped the fluttering sounds... thanks!
