AActor::ReceiveTick

function Engine Blueprint Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: UFUNCTIONBlueprintImplementableEventENGINE_API

Description

The Blueprint implementable version of Tick, called every frame when ticking is enabled. Implement the Event Tick node in Blueprint; override the C++ Tick() virtual instead for C++ subclasses.

Caveats & Gotchas

• In C++, override Tick() not ReceiveTick(). ReceiveTick is the generated thunk that fires the Blueprint event — calling or overriding it directly in C++ bypasses the Blueprint graph entirely.
• ReceiveTick is not called on dedicated servers if bAllowReceiveTickEventOnDedicatedServer is false (the default for new actors created after UE 4.24), even though C++ Tick() still runs.

Signature

UFUNCTION(BlueprintImplementableEvent, meta=(DisplayName = "Tick"))
ENGINE_API void ReceiveTick(float DeltaSeconds);

Parameters

Name	Type	Description	Default
DeltaSeconds	float	Elapsed game time since the last frame, in seconds.	—

Return Type

void

Examples

Rotate this actor each frame scaled by Delta Seconds Blueprint

C++ equivalent — override Tick instead C++

// In C++, override Tick(), not ReceiveTick().
void AMyActor::Tick(float DeltaSeconds)
{
	Super::Tick(DeltaSeconds);
	// Per-frame logic here
	ElapsedTime += DeltaSeconds;
}
