AActor::IsSelectionParentOfAttachedActors

function Engine Since 4.20

#include "GameFramework/Actor.h"

Access: public Specifiers: virtualENGINE_APIconst

Description

Returns whether this actor acts as a selection parent for its attached actors in the editor. When true, selecting a child also implies selection of this parent as a group.

Caveats & Gotchas

• This is an editor-only concept — the function is compiled in all builds but its result is only meaningful inside the editor. At runtime there is no selection system.
• The default implementation returns false. Override it in actors that logically group their children (e.g. procedural mesh generators or level instance roots) to get correct group-selection behavior in the editor.
• Must be consistent with IsSelectionChild() on the attached actors — mismatched overrides will produce confusing selection behavior in the editor viewport.
