UActorComponent::ReceiveTick

function Engine Blueprint Since 4.0

#include "Components/ActorComponent.h"

Access: public Specifiers: UFUNCTIONBlueprintImplementableEvent

Description

Blueprint-implementable event called every frame when ticking is enabled on the component. Implement this in a Blueprint subclass instead of overriding TickComponent in C++.

Caveats & Gotchas

• In C++ subclasses override TickComponent instead — ReceiveTick is generated glue code for the Blueprint VM and calling it directly from C++ is a no-op unless the Blueprint layer has an implementation.
• The component must have bComponentTickEnabled set to true and must be registered for this event to fire; disabled or unregistered components never receive it.

Signature

ENGINE_API void ReceiveTick(float DeltaSeconds)

Parameters

Name	Type	Description	Default
DeltaSeconds	float	Time in seconds since the last tick.	—

Return Type

void

Example

Blueprint Tick override equivalent in C++ C++

// Prefer TickComponent in C++ subclasses:
void UMyComponent::TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction)
{
	Super::TickComponent(DeltaTime, TickType, ThisTickFunction);
	// per-frame logic here
}
