UAudioComponent::HasCookedAmplitudeEnvelopeData
#include "Components/AudioComponent.h"
Access: public
Specifiers: constUFUNCTIONBlueprintCallable
Description
Returns whether the sound wave currently playing on this component has baked (cooked) amplitude envelope data available, false if none was found.
Caveats & Gotchas
- • Cooked envelope data must be enabled per-SoundWave asset at cook time — it is not generated automatically for every sound.
- • Returns false if nothing is currently playing, regardless of whether the assigned asset has envelope data.
- • Check this before calling GetCookedEnvelopeData() to avoid reading stale/default output on a sound without envelope data.
