FCurve.EndEdit
 
 
 

FCurve.EndEdit

Introduced

v3.0

Description

Stops recording bulk edits made to the fcurve and commits changes to the undo/redo stack. A call to EndEdit must follow a call to FCurve.BeginEdit.

Note: If you call EndEdit when there is no bulk edit in progress, the method raises an error. You can check if a bulk edit is in progress by using the FCurve.IsEditing method.

C# Syntax

FCurve.EndEdit();

Scripting Syntax

FCurve.EndEdit();

Examples

JScript Example

/*
        This JScript example illustrates how to use the editing recording feature
        of fcurves. This allows changes to be committed only after all edits have 
        been completed and undone if necessary.
