nw::snd::Sound3DManager::SetSonicVelocity Member Function

#include <nw/snd/snd_Sound3DManager.h>

void SetSonicVelocity(
     f32 sonicVelocity
);

	Name	Description
in	sonicVelocity	The sonic velocity.

None.

Sets the sonic velocity configured in 3D sound.

The set velocity is used in pitch change calculations, in accordance with the Doppler effect.

The units of the set value are the sonic velocity for a single frame. Since the speed of sound is approximately 340 m/s, if in the unit system for 3D space coordinates 1.0f is equivalent to 1 m and a sound is moved for 60 frames, the sonic velocity value must be set to 340.0f / 60.

If the sonic velocity is set to 0.0f, the Doppler effect will not occur. The default value is 0.0f.
