UAudioComponent::Activate

function Engine Since 4.0

#include "Components/AudioComponent.h"

Access: public Specifiers: virtualoverride

Description

Activates the component, which for UAudioComponent begins playing the assigned Sound if bAutoActivate is set or Activate() is called explicitly.

• Calling Activate() is not the same as calling Play() directly — Activate() is the ActorComponent-level entry point that auto-activation and construction-script wiring use, and it internally starts playback for an audio component.
• On a dedicated server, auto-activation via bAutoActivate is skipped for audio components even when bAutoManageAttachment is set, since server-side sound playback is meaningless.
• Override this in a derived component and always call Super::Activate(bReset) first, or the underlying sound will never start.

virtual void Activate(bool bReset=false) override

Name	Type	Description	Default
bReset	bool	If true, forces re-activation logic to run even if the component is already active.	false
