AActor::AddTickPrerequisiteComponent

function Engine Blueprint Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: virtualUFUNCTIONBlueprintCallable

Description

Forces this actor's tick to run after the specified component's tick has completed. Useful when the actor's logic depends on up-to-date data computed by a specific component.

Caveats & Gotchas

• Like AddTickPrerequisiteActor, this only applies to the actor's primary tick function, not to its components' tick functions.
• The prerequisite component must be registered and have ticking enabled; a disabled component tick will not block the actor's tick from firing.
