# reikhelm

A sandbox for game-system experiments. No single end goal — each idea is its
own self-contained system, built to learn and to see something cool run. The
best ones might get blended into an actual game someday; until then it's just
shipping for fun.

## How this repo works

- **One experiment per top-level folder.** Each is meant to stand on its own.
- **Mix and match freely.** When two systems are worth mashing up, write glue
  code between them. It doesn't have to be pretty.
- **Rust or Python**, whatever fits the idea. Rust experiments can be standalone
  Cargo projects or join the workspace below for easy path-dependency glue.

## What's here so far

### Procedural dungeon generator (Rust)
A deterministic 2D map generator built from small composable **passes** over a
shared context (BSP → rooms → caves → connect → corridors → doors → pools →
pillars → entities). Towns/dungeons are different **recipes** drawn from one
primitive vocabulary (Partitioner / Shaper / Connector / Placer / Decorator).

- `reikhelm-core/` — pure generation library, no rendering deps (the `Map`
  struct is the contract; renderers own all art).
- `reikhelm-wasm/` — `wasm-bindgen` bridge that compiles core to wasm32.
- `reikhelm-viz/` — original macroquad renderer (**frozen** — kept, not maintained).

### Browser playground & first-person explorer (JS + Canvas)
- `reikhelm-web/` — live procgen playground (reroll / seed / config sliders /
  per-pass scrubber) in an atmospheric torch-lit style, plus a top-down and a
  first-person (Eye-of-the-Beholder style) renderer and a walkable explorer.

### AI-render → pixel-art pipeline (Python)
- `tools/` — depth map → local diffusion render (Z-Image on the LAN
  workstation) → Floyd–Steinberg dither through a 256-color palette → signature
  pixel art. See `tools/README.md`.

### Combined-pool combat system (Rust + Python)
- `combat/` — a deterministic, headless combat engine built on one combined
  `Vigor` pool (HP + mana + stamina merged), so offense literally spends your
  survival. Sim-first: a pure Rust core (`combat-core`) + a batch sweep harness
  (`combat-sim`) that runs tens of thousands of fights and exports metrics, plus a
  Python analysis layer that measures "feel" (difficulty curve, fight duration)
  instead of eyeballing it. Its own Cargo workspace. See `combat/README.md`.

## Building

```sh
# Rust workspace (host-native crates)
cargo build            # builds reikhelm-core + reikhelm-viz
cargo test

# Browser playground (wasm)
wasm-pack build reikhelm-wasm --dev --target web \
  --out-dir ../reikhelm-web/pkg --out-name reikhelm_wasm
python3 -m http.server 8011 --directory reikhelm-web
```

`~/.cargo/bin` may not be on the non-interactive shell PATH — prepend
`export PATH="$HOME/.cargo/bin:$PATH"` to cargo commands if they're not found.
