AActor::UninitializeComponents

function Engine Since 4.0

#include "GameFramework/Actor.h"

Access: public

Description

Iterates over all components and calls UninitializeComponent on each one. Called when the actor is ending play, mirroring InitializeComponents.

Caveats & Gotchas

• This is called as part of EndPlay teardown — do not call it manually unless you are implementing a custom actor lifecycle, as double-uninitializing a component is undefined behaviour.
• UninitializeComponent is symmetric to InitializeComponent; resources acquired there should be released here, not in BeginDestroy.

Signature

ENGINE_API void UninitializeComponents();

Return Type

void

Example

Component override that pairs with InitializeComponent C++

void UMyComponent::UninitializeComponent()
{
    // Release resources acquired in InitializeComponent
    MySubsystemHandle.Reset();
    Super::UninitializeComponent();
}
