Microsoft DirectX 8.1 (Visual Basic)

DirectSound3DListener8.SetOrientation

The SetOrientation method sets the listener's orientation in terms of a front vector and a top vector.

Syntax

object.SetOrientation( _
  xFront As Single, _
  yFront As Single, _
  zFront As Single, _
  xTop As Single, _
  yTop As Single, _
  zTop As Single, _
  applyFlag As CONST_DS3DAPPLYFLAGS)

Parts

object

Resolves to a DirectSound3DListener8 object.

xFront, yFront, zFront

Values that specify the coordinates of the front orientation vector.

xTop, yTop, zTop

Values that specify the coordinates of the top orientation vector.

applyFlag

Value that specifies when the setting should be applied. Must be one of the constants of the CONST_DS3DAPPLYFLAGS enumeration.

Error Codes

If the method fails, an error is raised and Err.Number may be set to DSERR_INVALIDPARAM.

Remarks

The front vector points in the direction of the listener's nose, and the top vector points in the direction of the top of the listener's head. By default, the front vector is (0,0,1.0) and the top vector is (0,1.0,0).

The top vector must be at right angles to the front vector. If necessary, DirectSound adjusts the top vector after setting the front vector.
