Blueprint reference

Find verified Blueprint component, utility, audio, and shared data references for the Convai Unreal Engine plugin runtime workflow.

The Blueprint reference documents the core runtime Blueprint surface for the Convai Unreal Engine plugin: the chatbot, player, and object components; shared structs and enums; microphone capture; and cross-cutting utility libraries. Use these pages when you need exact property names, function signatures, defaults, categories, and constraints.

Feature-specific Blueprint nodes — actions parameter accessors, dynamic context transport details, emotion helpers, long-term memory (LTM) nodes, vision, and narrative design — live in each feature's own Blueprint reference page. The Convai Subsystem connection surface is documented in Session lifecycle, not here.

Convai Chatbot Component Properties, functions, and events for the AI character component, including session, identity, lip sync, vision, and environment APIs.

Convai Player Component Properties, functions, and events for the player component, including identity, session, microphone capture, streaming, and gaze attention.

Convai Object Component Properties, functions, and events for the world object tagging component, including tracked properties, proximity state, and gaze callbacks.

Microphone and audio capture Microphone device structs, player-component capture functions, the audio capture component, and Android permission requirements.

Convai utility functions Blueprint libraries for look-at helpers, component lookups, settings accessors, blendshape tools, file I/O, and connection pre-warming.

Data types and enums Shared Blueprint structs and enums used across components, including object entries, action types, connection states, and VAD settings.
