Second game mode selectable at dog select (host-authoritative online): - js/sim_arena.js: top-down sim, same export surface as sim.js — x/y plane plus a z hop axis (Space / comma); KOs by knocking dogs into abyss pits - js/mapgen_arena.js: mirrored symmetric arenas — walls, pits, center clearing, guaranteed spawn-to-center corridors, crystals/spikes/launch pads, mirrored saw pairs; fallback pit pair since pits are the only KO mechanic - specials re-imagined per dog: zoom dash, ram + hop-slam, zip-leash slingshot, blink, hover (floats over pits/saws/spikes) - render: arena tiles with wall shadows + void pits, top-down dog drawing with z-lift over a ground shadow; new fall event/sfx - B.HOP input bit so 'up' can mean north in top-down (Space also jumps in side view); mode toggle UI + mode carried in start/rematch net messages Tested: arena mapgen determinism/symmetry/connectivity + chaotic matches + pit/hop scenarios headless; local chaos + full P2P arena match (host mode flip syncs to client) in two headless browsers with zero page errors.

# BARKOUR 🐕💨
|
||
|
||
**Dogfights × parkour.** A 2-player movement-PvP fighting game: five dogs with
|
||
wildly different movement physics brawl across procedurally generated arenas
|
||
full of traps and mineable powerups. Last dog standing wins.
|
||
|
||
Two arena styles, picked at dog select:
|
||
|
||
- **⛰ Parkour** (side view) — gravity, wall-jumps, one-way platforms, blast-zone KOs.
|
||
- **🐾 Dogpit** (top-down) — 8-way movement on a dota-style mirrored arena;
|
||
hop (third axis) over saws, spikes and abyss pits; KO by knocking dogs into the void.
|
||
|
||
No build step, no game server, no asset files — everything (art, sound, maps)
|
||
is generated procedurally in the browser.
|
||
|
||
## Run it
|
||
|
||
```bash
|
||
npm run dev # python http.server on :8137
|
||
# → http://localhost:8137
|
||
```
|
||
|
||
Any static file server works (ES modules just need http://, not file://).
|
||
|
||
## Play
|
||
|
||
| | Move | Bite | Special | Item | Hop (top-down) |
|
||
|---|---|---|---|---|---|
|
||
| **P1** | WASD | F | G | H | Space |
|
||
| **P2** | arrows | K | L | ; | , |
|
||
|
||
- Side view: **↑/W** jumps (Space works too for P1), **↓** drops through one-way platforms
|
||
- Top-down: **Space/,** hops over pits, saw blades, spikes and bites
|
||
- **Bite** is also your mining pick — crack open crystals for powerups
|
||
- Damage % makes knockback grow (Smash-style); die by being launched past
|
||
the arena edges or into the abyss. 3 stocks each.
|
||
- **M** mute, **Esc** pause/leave, **Enter** rematch
|
||
|
||
### Online play (P2P)
|
||
|
||
One player clicks **Host online room** and shares the 5-letter key; the other
|
||
clicks **Join with room key**. The PeerJS public cloud is used for signaling
|
||
only — all game traffic flows directly peer-to-peer over a WebRTC data channel.
|
||
No server of ours is involved. (Host is authoritative; the joiner streams
|
||
inputs and renders snapshots.)
|
||
|
||
## The dogs
|
||
|
||
| Dog | Breed | Parkour (side) | Dogpit (top-down) |
|
||
|---|---|---|---|
|
||
| **Bolt** | Greyhound | Wall-slide/wall-jump, 8-way air dash | 8-way zoom dash on cooldown |
|
||
| **Brick** | Bulldog | Charging ram, ground-pound shockwave | Same ram; slam down from a hop |
|
||
| **Lasso** | Lurcher | Pendulum leash-swing, jump-release launch | Zip-leash: latch a wall, reel in, slingshot out |
|
||
| **Wisp** | Saluki | Low gravity, double jump, blink through walls | Blink through walls and over pits |
|
||
| **Stubbs** | Corgi | Jetpack, butt-bounce off hard landings | Hover — floats over pits, saws and spikes |
|
||
|
||
All dogs keep their weight class: Brick barely launches, Wisp flies across the map.
|
||
|
||
## Arenas
|
||
|
||
Every match generates a fresh seeded arena: stepped terrain, abyss pits,
|
||
wall-jump towers, floating islands, one-way platforms, spike patches, bounce
|
||
pads, rail saws on patrol routes, and crystal outcrops. Mine crystals (or bomb
|
||
them) for: tennis-ball launcher, bomb, shield, speed boost, heal. A care
|
||
package also parachutes in periodically.
|
||
|
||
## Tests
|
||
|
||
```bash
|
||
npm test # headless sim smoke test (node, no browser needed)
|
||
```
|
||
|
||
The sim core (`js/sim.js` + deps) is DOM-free by design: maps are seeded and
|
||
deterministic, matches run headlessly. See `MAP.md` for the code layout.
