# MRP3GI — Monster Robot Party 3D Game Interpreter

The **third generation** of the Monster Robot Party engine family:

| Engine | Sierra analog | The trick |
|---|---|---|
| [MRPGI](https://github.com/) (`~/Documents/mrpgi`) | AGI (1984) | 16-color vector rooms, text parser |
| [MRPCI](https://github.com/) (`~/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](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)

```sh
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
```
