DirectSound3DBuffer.SetConeAngles

The DirectSound3DBuffer.SetConeAngles method sets the inside and outside angles of the sound projection cone for this sound buffer.

object.SetConeAngles(inCone As Long, _
    outCone As Long, _
    applyFlag As CONST_DS3DAPPLYFLAGS)

Parameters

object
Object expression that resolves to a DirectSound3DBuffer object.
inCone and outCone
Inside and outside angles of the sound projection cone, in degrees.
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.

For information on trapping errors, see the Visual Basic Error Trapping topic.

Remarks

The minimum, maximum, and default cone angles are defined as DS3D_MINCONEANGLE, DS3D_MAXCONEANGLE, and DS3D_DEFAULTCONEANGLE. Each angle must be in the range of 0 degrees (no cone) to 360 degrees (the full sphere). The default value is 360.
