UActorComponent::UninitializeComponent

function Engine Since 4.0

#include "Components/ActorComponent.h"

Access: public Specifiers: virtual

Description

Called from AActor::EndPlay only if InitializeComponent was previously called. Override to release any resources or references acquired during InitializeComponent.

Caveats & Gotchas

• Only called if bHasBeenInitialized is true, which requires bWantsInitializeComponent to have been true. If you override UninitializeComponent without also overriding InitializeComponent (and setting bWantsInitializeComponent), it will never be called.
• This is called before EndPlay in the component lifecycle, during EndPlay of the owning actor. Do not rely on other components still being valid here — they may already be uninitializing in an undefined order.
