Parameter |
Description |
||||||||||||||||||||||||
|
|
||||||||||||||||||||||||
nPlayerIndex |
Number representing the zero-based index of the involved player |
||||||||||||||||||||||||
strVolumePointName |
String representing the friendly name of the volume point to remove: this name must be identical to the corresponding one used for adding the volume point through the VolumeAutomation.PointAdd method. |
||||||||||||||||||||||||
fPosition |
Position of the volume point expressed in the same unit set into the VolumeAutomation.PositionUnit property. |
||||||||||||||||||||||||
fVolumeLevel |
Volume level expressed in the same unit set into the VolumeAutomation.ScaleType property |
||||||||||||||||||||||||
nCurveType |
Type of curve applied to reach the next volume point. Supported values are the following:
|
||||||||||||||||||||||||
nDesignerUniqueId |
Unique identifier of the curve editor control containing custom curve settings to apply. This unique identifier is returned by a previous call to the VolumeAutomation.CurveDesigner.Create method.
The custom curve designer manages a windowed control, whose visual aspect can be defined programmatically, which allows designing volume curves based upon Bézier curves whose shape is defined through the manual positioning of 2 control points (displayed in cyan color on the graphic below). For further information about the use of the embedded CurveDesigner refer to the tutorial How to create custom volume curves.
This parameter is ignored if the nScaleType parameter above has been set to a value different from VOLUME_CURVE_CUSTOM. |
