AActor::NotifyActorOnInputTouchLeave

function Engine Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: virtual

Description

Called when a touch finger moves off this actor while touch-events are enabled. Use this to revert visual or state changes applied in NotifyActorOnInputTouchEnter.

Caveats & Gotchas

• As with the Enter variant, requires bEnableTouchOverEvents on the PlayerController. If the actor is destroyed while a finger is over it, the Leave event may not fire.
• Does not fire when the finger is lifted from the screen — that is NotifyActorOnInputTouchEnd. Touch-leave only fires when the finger slides off the actor while still in contact with the screen.
