# 🦖 Dino Isle Online
|
||
|
||
A multiplayer dino-survival island game in the spirit of *The Isle* — playable
|
||
in any browser. Eat, drink, rest, grow through 4 evolution stages, hunt AI prey,
|
||
and devour the other players.
|
||
|
||
**Zero dependencies** — pure Node.js (HTTP + hand-rolled WebSocket) and vanilla
|
||
JS canvas on the client.
|
||
|
||
## ▶ Play
|
||
|
||
```
|
||
node server.js # default port 8095 (PORT=xxxx node server.js to change)
|
||
```
|
||
|
||
Open **http://localhost:8095** — open more tabs / other devices on the LAN for
|
||
multiplayer. Everyone plays on the same persistent island.
|
||
|
||
## 🎮 How to survive
|
||
|
||
| Key | Action |
|
||
|---|---|
|
||
| `WASD` / arrows | Move |
|
||
| `Shift` | Sprint (drains stamina) |
|
||
| `Space` / left click | Bite (hunt & fight) |
|
||
| `E` (hold) | Context action: eat carcass · graze plants · drink at water |
|
||
| `R` | Rest — regenerates stamina/HP fast, but you're defenseless |
|
||
| `Enter` | Chat · `M` mute |
|
||
|
||
### Survival loop
|
||
- **Food** decays constantly; sprinting drains it faster. Starving hurts.
|
||
- **Water** decays faster; stand in shallow water or at the shore and hold `E`.
|
||
- **Health** only regenerates when fed & hydrated — or fast while resting.
|
||
- **Growth**: every meal gives XP → **Hatchling → Adolescent → Adult → Apex**.
|
||
Each stage makes you visibly bigger, stronger and tougher (camera zooms out).
|
||
- Diets matter: herbivores graze grass patches & berry bushes, carnivores hunt,
|
||
omnivores eat everything.
|
||
- **Fauna**: skittish critters roam land, fish shoals dart around shallows — wade
|
||
in and time your bite when they tire — and **AI dinosaur herds** (*Dryosaurus*,
|
||
*Psittacosaurus*) graze the plains: medium prey that flee hard but drop big
|
||
carcasses worth feasting on.
|
||
- **PvP**: everyone can attack everyone. Kills drop a carcass — feast on your
|
||
rivals for big XP. Death shows a recap screen; respawn keeps playing.
|
||
- Watch the day/night cycle — nights are dark and dangerous.
|
||
|
||
### 🛠 Developer mode (testing helpers)
|
||
Press **`` ` ``** (backquote) in-game to toggle. While active:
|
||
- God-mode: no hunger/thirst decay, HP & stamina stay full
|
||
- **×6 growth XP**, ×2.5 bite damage, +28% speed
|
||
- Hotkeys: **`1`** full heal · **`2`** evolve one stage instantly ·
|
||
**`3`** spawn an AI dino nearby · **`Alt+Click`** teleport to cursor
|
||
|
||
## 🧪 Tests
|
||
|
||
```
|
||
node test/smoke.mjs # headless 2-player integration test (join, sync, move,
|
||
# hunt, AI-dino hunt, PvP kill, carcass feast, respawn,
|
||
# chat, developer mode)
|
||
node test/visual.mjs # real-browser UI test via playwright-core (menu → play)
|
||
```
|
||
|
||
## 🗂 Structure
|
||
|
||
```
|
||
server.js HTTP static server + WebSocket upgrade + game loop (20 Hz tick)
|
||
sim.js Authoritative simulation: species, needs, growth, AI, combat
|
||
worldgen.js Seeded island generation (tiles, forest decor, spawns)
|
||
ws.js Minimal RFC6455 WebSocket implementation (no deps)
|
||
public/ index.html · style.css · client.js (canvas renderer, prediction)
|
||
test/smoke.mjs Headless multiplayer smoke test
|
||
```
|
||
|
||
Notes: `DEBUG_CHEATS=1` enables a `{t:'tp'}` teleport message used by tests.
