AActor::NotifyActorBeginCursorOver

function Engine Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: virtual

Description

Called by the engine when the mouse cursor first moves over this actor while click-events are enabled on the player controller. Override to add hover logic in C++.

Caveats & Gotchas

• Only fires when bEnableMouseOverEvents is true on the owning PlayerController. It is off by default and must be explicitly enabled.
• The C++ virtual is paired with the Blueprint event ReceiveActorBeginCursorOver; if you override in C++ you must call Super if subclasses or Blueprint overrides are expected to fire.

Example

Highlight actor on mouse-over C++

void AMyActor::NotifyActorBeginCursorOver()
{
    Super::NotifyActorBeginCursorOver();
