UAudioComponent::GetAudioComponentID

function Engine Since 4.0

#include "Components/AudioComponent.h"

Access: public Specifiers: constinline

Description

Returns the unique instance ID assigned to this audio component, used internally to correlate it with active sounds on the audio render thread.

Caveats & Gotchas

• This is a runtime-only handle, not a stable identifier — it is assigned from a global counter and is not the same as AudioComponentUserID, which is a serialized, designer-facing name.
• The ID is only meaningful while the component exists; use it with GetAudioComponentFromID() to look the component back up from audio-thread callbacks where holding a raw UObject* would be unsafe.

Signature

uint64 GetAudioComponentID() const { return AudioComponentID; }

Return Type

uint64

Example

Look up owning component from an audio-thread callback C++

uint64 ComponentID = AudioComponent->GetAudioComponentID();
// ... later, possibly on a different thread ...
if (UAudioComponent* Found = UAudioComponent::GetAudioComponentFromID(ComponentID))
{
    // Safe to use Found on the game thread
}
