UActorComponent::PrimaryComponentTick

property Engine Since 4.0

#include "Components/ActorComponent.h"

Access: public Specifiers: UPROPERTYEditDefaultsOnly

Description

The primary tick function for this component. Configure it in the constructor to control whether and how the component ticks.

Caveats & Gotchas

• You must set PrimaryComponentTick.bCanEverTick = true in the constructor before the component is registered, or TickComponent will never be called — setting it after registration has no effect.
• Tick prerequisites (AddTickPrerequisiteComponent, AddTickPrerequisiteActor) must be configured before or during registration. Adding prerequisites at runtime after BeginPlay requires re-registration or explicit ordering via the TickTaskManager.

Signature

UMyComponent::UMyComponent()
{
	PrimaryComponentTick.bCanEverTick = true;

}
