MRP3GI — Monster Robot Party 3D Game Interpreter

The third generation of the Monster Robot Party engine family:

Engine	Sierra analog	The trick
MRPGI (~/Documents/mrpgi)	AGI (1984)	16-color vector rooms, text parser
MRPCI (~/Documents/mrpci)	SCI0/SCI1 (1988–92)	256-color palettes, point-and-click, rhai scripts
MRP3GI (this repo)	SCI32 / Phantasmagoria-era (1995+)	3D presentation, 2D brain

One sentence: the MRPCI story engine, compiled to WASM, drives rigged GLB characters in a three.js scene — Grim-Fandango-style: the sim stays a deterministic 2D adventure engine; the camera, sets, lighting and Mixamo animation are presentation.

Read SPEC.md for the full architecture and the milestone plan. Nothing in this repo reimplements game rules: if it decides whether a door opens, it lives in mrpci-core. If it decides what a door looks like, it lives here.

Prerequisites

• mrpci checked out as a sibling directory (../mrpci) — the bridge crate uses a path dependency
• Rust (stable) + wasm-pack; Node 20+ + npm
• The demo game: cd ../mrpci && cargo run -p mrpci-core --bin mrpci-headless -- --sample

Quick start (once M2 lands)

npm install
npm run bridge     # wasm-pack build of the Rust story core
npm run dev        # vite dev server → play Neon Precinct in 3D
npm test           # incl. the golden determinism replay vs native
