3D Audio does not fade out by distance. #267

Hey there, I am using the latest 20200207 release. I implemented soloud into my game engine(OpenGL).

Although, having trouble with 3d audio fade out and pan. I can notice a slight change when I use set3dListenerAt while my camera rotates. But the position does not change anything. I call update3dAudio after I set my camera position and rotation in my main loop and call update audio method though.

Hello,

the default attenuation model is "no attenuation". So if you want your 3D sound to be faded away as distance increases, you need to set a proper attenuation model. For example:

m_handleFallYell = soloud.play3d(m_sndFallYell, playerPos.getX(), playerPos.getY(), playerPos.getZ());
soloud.set3dSourceMinMaxDistance(m_handleFallYell, 9.f, 22.f);
soloud.set3dSourceAttenuation(m_handleFallYell, SoLoud::AudioSource::ATTENUATION_MODELS::LINEAR_DISTANCE, 1.f);
