Reconquer Engine – A Full-Stack JavaScript Mmorpg Engine and Game

Hacker News

Hi everyone, I'm Chris, the developer of Reconquer Online ( https://alpha.reconquer.online/ ). Today, I'm excited to share Reconquer Engine https://github.com/ReconquerOnline/reconquer-engine . Reconquer Engine provides all the necessary logic and game assets to build an OSRS-style MMORPG using Javascript. Upon building and running it for the first time, you'll have a fully functional MMORPG. It utilizes gltf-Transform for asset processing, a Node.js server with Express and Socket.io, and WebGL/three.js for browser-based graphics. Simple example implementations for the database, authentication, and payments are included, but you are encouraged to integrate your own systems. The game and engine are developed purely in Javascript (99.9% JS, 0.1% HTML, 0% CSS) including the asset exporter, server, and client. My Development Workflow: 1. Blender: I create, texture, and animate 3d models. 2. JSON Configuration: For each asset, I define its type and properties in a JSON config file (e.g., inventory item, scenery). 3. Custom Exporter: A JavaScript tool I built iterates through these config files and generates optimized assets for both the client and server. 4. Compilation & Server Start: I compile the frontend Javascript and launch the Node.js server. Licensing: Reconquer Engine is released under a license similar to Unreal Engine's: free for non-commercial and small commercial use, with a royalty for larger commercial ventures. Limitations: There is very little documentation, although the code and structure itself is designed to be as simple as possible. I think the codebase can be learned fairly quickly through inspection or with an LLM helper. Future Plans: * I'm working on creating a comprehensive tutorial to help others get started. * I plan to further improve the tooling, with the potential goal of creating a browser-based MMORPG maker. * I'm also exploring the development of an AI agent to very easily create new content. Please try it out! It's very easy to get up and running. Also, I plan on posting a tutorial on my Youtube channel ( https://www.youtube.com/channel/UCEqXVu4orzl7nnkwJZ72AOg ) Thank you for checking it out! Best, Chris @ Reconquer Games
