DirectSound3DListener.SetOrientation

The DirectSound3DListener.SetOrientation method sets the listener's current orientation in terms of two vectors: a front vector and a top vector.

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

Parameters

object

Object expression that resolves to a DirectSound3DListener object.

xFront, yFront, and zFront

Values that represent the coordinates of the front orientation vector.

xTop, yTop, and zTop

Values that represent the coordinates of the top orientation vector.

applyFlag

Value indicating when the setting should be applied. This value must be one of the following constants of the CONST_DS3DAPPLYFLAGS enumeration:

DS3D_DEFERRED

Settings are not applied until the application calls the DirectSound3DListener.CommitDeferredSettings method. This allows the application to change several settings and generate a single recalculation.

DS3D_IMMEDIATE

Settings are applied immediately, causing the system to recalculate the 3-D coordinates for all 3-D sound buffers.

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 out 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 front vector after setting the top vector.
