A modular dialogue and interaction framework for Unity, with reusable NPCs, memory conditions, inspectable objects, levers, doors, voice support, and a complete demo.Ballai Dialogue and Interaction System provides a modular foundation for building dialogue-driven interactions in Unity 2D projects.Create dialogue using customizable ScriptableObject sequences with per-line speakers, optional voice clips, typewriter effects, manual progression, and several automatic advance modes. The included session memory system supports conditional dialogue, returning NPC conversations, interaction state, and event-driven world changes.The interaction framework includes reusable NPCs, inspectable objects, dialogue triggers, levers, and animated doors. Components communicate through explicit references, interfaces, events, and configurable memory conditions instead of requiring game-specific managers.The package is suitable for RPGs, adventure games, metroidvanias, narrative games, puzzle games, and other 2D projects requiring dialogue or environmental interactions. Inspector configuration, replaceable UI and voice adapters, documented APIs, and an included dungeon demo make the package straightforward to customize.An optional integration adapter is included for the Ballai Save System. The Dialogue and Interaction System works independently and does not require the Save System.ScriptableObject-based dialogue sequencesManual and automatic dialogue progressionPer-line speaker overridesOptional voice clips and voice adaptersConfigurable typewriter effectSkippable text revealInput-system-independent interaction APIReusable NPC and returning-dialogue componentsConditional dialogue using session memory flagsAll, any, and excluded memory conditionsInspectable objects and dialogue triggersReusable lever and animated door interactionsUnityEvent and C# event integration pointsReplaceable dialogue UI adapterOptional uGUI integrationOptional Ballai Save System integrationOrganized runtime, integration, sample, test, and documentation foldersComplete three-chamber dungeon demoBeginner-friendly setup documentationNo required third-party assets or paid dependenciesAI-assisted development tools, including OpenAI Codex, were used during the extraction and commercialization process. AI assisted with code generation and refactoring, dependency removal, test creation, documentation, demo setup, and identifying potential lifecycle and integration issues.The package architecture, feature requirements, interaction flow, public API decisions, testing process, manual Unity configuration, and final validation were directed and reviewed by the publisher. All generated or modified content was inspected and tested before submission.
