B1AnimNotifyState_VoiceInteraction

File: BlueClient2/Source/BlueClient/Animation/AnimNotifies/B1AnimNotifyState_Voice.h / .cpp Base Class: UAnimNotifyState

Purpose

Plays a voice line (resolved from a named voice resource) during an interaction animation. Supports async audio asset loading with a configurable delay. The voice clip is stopped cleanly when the notify range ends or the montage is interrupted.

How to Add in the Editor

1. Open an Animation Montage or Animation Sequence.
2. Right-click on the Notify track → Add Notify State → B1AnimNotifyState_VoiceInteraction.
3. Set VoiceResourceId in the Details panel and drag the bar to cover the voice clip duration.

Editor Properties

Property	Type	Default	Description
VoiceResourceId	FName	—	ID of the voice resource defined in the character's voice data asset

Behavior

Callback	Action
NotifyBegin	Calls AB1Character::GetVoiceResource(VoiceResourceId) to resolve the audio asset. Creates a FB1NotifyStateVoiceKey (contains mesh, animation, timing, montage instance info). Spawns the sound attached to the head socket via UB1AudioManager::SpawnSoundAttached(). Supports async loading with configurable delay (console variable).
NotifyEnd	Stops the audio component and removes the entry from the internal map

Async Loading

If the voice audio asset is not yet loaded when NotifyBegin fires, the sound spawn is deferred by a configurable number of frames (controlled via a console variable). This prevents hitches in streaming scenarios.
