AActor::ReceiveActorOnInputTouchBegin

function Engine Blueprint Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: UFUNCTIONBlueprintImplementableEvent

Description

Blueprint implementable event called when a touch input begins on this actor. Override in Blueprint to respond to touch start without needing dynamic delegates.

Caveats & Gotchas

• This is the Blueprint-facing counterpart to the OnInputTouchBegin C++ delegate. In C++ subclasses you can override NotifyActorOnInputTouchBegin() instead, which is the virtual that calls this event.
• Has no C++ body to override directly — it is a BlueprintImplementableEvent. For C++ logic, bind to OnInputTouchBegin or override NotifyActorOnInputTouchBegin.

Signature

void ReceiveActorOnInputTouchBegin(const ETouchIndex::Type FingerIndex)

Parameters

Name	Type	Description	Default
FingerIndex	const ETouchIndex::Type	Which finger triggered the touch event.	—

Return Type

void

Example

C++ override of the underlying notify virtual C++

// Override the virtual that fires this BP event in C++
void AMyActor::NotifyActorOnInputTouchBegin(const ETouchIndex::Type FingerIndex)
{
    Super::NotifyActorOnInputTouchBegin(FingerIndex);
    // C++ logic here — ReceiveActorOnInputTouchBegin is called by Super
    HandleTouchStart(FingerIndex);
}
