BASS_ChannelSet3DPosition

Sets the 3D position of a sample, stream, or MOD music channel with 3D functionality.

BOOL BASS_ChannelSet3DPosition(
    DWORD handle,
    BASS_3DVECTOR *pos,
    BASS_3DVECTOR *orient,
    BASS_3DVECTOR *vel
);

Parameters

handle	The channel handle... a HCHANNEL, HMUSIC, HSTREAM.
pos	Position of the sound... NULL = leave current.
orient	Orientation of the sound... NULL = leave current. This is automatically normalized.
vel	Velocity of the sound... NULL = leave current. This is only used to calculate the doppler effect, and has no effect on the sound's position.

If successful, then TRUE is returned, else FALSE is returned. Use BASS_ErrorGetCode to get the error code.

BASS_ERROR_HANDLE	handle is not a valid channel.
BASS_ERROR_NO3D	The channel does not have 3D functionality.

As with all 3D functions, BASS_Apply3D must be called to apply the changes made.
