Sets the position, velocity, and orientation of the listener (ie. the player).

BOOL WINAPI BASS_Set3DPosition(     BASS_3DVECTOR *pos,     BASS_3DVECTOR *vel,     BASS_3DVECTOR *front     BASS_3DVECTOR *top );

Parameters

pos	The position of the listener... NULL = leave current.
vel	The listener's velocity in units (as set with BASS_Set3DFactors) per second... NULL = leave current. This is only used to calculate the doppler effects, and in no way affects the listener's position.
front	The direction that the listener's front is pointing... NULL=leave current.
top	The direction that the listener's top is pointing... NULL = leave current.

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

Error codes

BASS_ERROR_NO3D

BASS_Init has not been successfully called with BASS_DEVICE_3D specified in the flags parameter.

Remarks
The front and top parameters must both be set in a single call, they can not be set individually. As with all 3D functions, use BASS_Apply3D to apply the changes.
