UAudioComponent::AdjustVolumeInternal
#include "Components/AudioComponent.h"
Access: public
Description
Shared implementation behind AdjustVolume, FadeIn, and FadeOut that queues a volume interpolation on the component's active sound.
Caveats & Gotchas
- • Not a UFUNCTION and not Blueprint-callable — call the public wrappers AdjustVolume, FadeIn, or FadeOut instead of this directly.
- • bIsFadeOut changes internal bookkeeping (e.g. sets bIsFadingOut) in addition to driving the interpolation curve, so calling it directly with the wrong flag can desync the reported play state.
Signature
void AdjustVolumeInternal(float AdjustVolumeDuration, float AdjustVolumeLevel, bool bIsFadeOut, EAudioFaderCurve FadeCurve)Parameters
| Name | Type | Description | Default |
|---|---|---|---|
| AdjustVolumeDuration | float | Length of time, in seconds, to interpolate between the current volume and AdjustVolumeLevel. | — |
| AdjustVolumeLevel | float | The target volume multiplier to interpolate to. | — |
| bIsFadeOut | bool | Whether this adjustment should be treated as a fade-out, affecting internal play-state bookkeeping. | — |
| FadeCurve | EAudioFaderCurve | The interpolation curve to use between the old and new volume. | — |
Return Type
void Example
Direct volume interpolation C++
AudioComponent->AdjustVolumeInternal(1.5f, 0.25f, /*bIsFadeOut=*/false, EAudioFaderCurve::Logarithmic);Tags
