Each character has a HEXACO personality profile (six dimensions) and uses a 9-dimensional cognitive appraisal model to compute emotional responses in VAD (Valence-Arousal-Dominance) space. Personality shapes how characters react to interactions like praise or betrayal, relationships accumulate over time, and mood shifts gradually rather than instantly. The tech stack uses React 19, Canvas 2D, TypeScript, and the molroo SDK for emotion computation. The project is open source with a live demo available, and the author invites discussion on continuous emotion models in games. ## Full article daily.dev links to this article rather than hosting it.

The real value isn’t the sim itself, it’s the framework for believable, evolving behavior. ## Similar posts on daily.dev - [Building a Nostalgic 8-bit Universe with Modern Tech: A Vibe Coding Journey](https://daily.dev/posts/building-a-nostalgic-8-bit-universe-with-modern-tech-a-vibe-coding-journey-bmjowhcuw) · Codrops · 52 upvotes · 5 comments - [Persona Atlas: Mapping How Famous Minds Think](https://daily.dev/posts/persona-atlas-mapping-how-famous-minds-think-adsfxhz5z) · Hugging Face · 1 upvotes · 0 comments --- Tags: [#ai](https://daily.dev/tags/ai), [#react](https://daily.dev/tags/react), [#game-development](https://daily.dev/tags/game-development) [View this post on daily.dev](https://daily.dev/posts/i-built-a-pixel-art-village-where-ai-characters-have-real-emotions-ovhzrhtbi) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"I Built a Pixel Art Village Where AI Characters Have Real Emotions","url":"https://daily.dev/posts/i-built-a-pixel-art-village-where-ai-characters-have-real-emotions-ovhzrhtbi","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/i-built-a-pixel-art-village-where-ai-characters-have-real-emotions-ovhzrhtbi"},"datePublished":"2026-03-06T16:09:12.841Z","dateModified":"2026-03-06T16:09:33.681Z","description":"A developer built Persona World, an open-source pixel art village simulation featuring 12 AI characters with dynamic emotional states.
