Simple A Rec Room Multiplayer Engine in Scratch is a framework designed to mimic the core social and physical aspects of Rec Room—typically translated into a 2D top-down or pseudo-3D/raycaster perspective. Instead of a massive, open-world MMO, it focuses on small-scale rooms (lobbies) of 2 to 8 players where users can: Interact in real-time with custom avatars (customizable heads, torsos, and hands). Move around a shared lounge or clubhouse. Pick up and throw physical objects (like dodgeballs, frisbees, or basketballs). Join mini-games (like Paintball or Golden Trophy) via in-game portals. Core Technical Features of the Engine To make this work within Scratch's limitations, the engine relies on three major systems: 1. Cloud Variable Encoding and Decoding Scratch only allows up to 10 Cloud Variables per project, and they can only store numbers (no letters or symbols), with a limit of 256 characters per variable. The Pack/Unpack System: To send player data across the internet, the engine translates text (like usernames or costumes) into number codes (e.g., "A" = 01, "B" = 02). Data Bundling: Every frame, the engine packs your X position, Y position, facing direction, hand positions, and costume ID into one long number string and sends it to the cloud.
