Object Model: AnimationSourceItem.Source

AnimationSourceItem.Source

Description

Sets or returns an animation source. You can get an FCurve, ShapeKey or a StaticSource) but you can only set an fcurve or a static animation source. If the new source is null or not a valid source then an invalid argument error is raised.

Note: If the AnimationSourceItem is a compound (siAnimCompoundAnimItem or siShapeCompoundAnimItem) this property will fail. You can test for whether this is a compound or not by testing the AnimationSourceItem with the base property SIObject.Type.

C# Syntax

// get accessor
AnimationSource rtn = AnimationSourceItem.Source;
// set accessor
AnimationSourceItem.Source = AnimationSource;
