Timmy Tower World
A Three.js 3D visualization of the Timmy agent network. Agents appear as glowing icosahedra connected by lines, pulsing as they process jobs. A matrix-rain particle effect fills the background.
Quick start
npm install
npm run dev # Vite dev server with hot reload → http://localhost:5173
npm run build # Production bundle → dist/
npm run preview # Serve dist/ locally
Configuration
Set these in a .env.local file (not committed):
VITE_WS_URL=ws://localhost:8080/ws/agents
Leave VITE_WS_URL unset to run in offline/demo mode (agents animate but
receive no live updates).
Adding custom agents
Edit one file only: js/agent-defs.js
export const AGENT_DEFS = [
// existing agents …
{
id: 'zeta', // unique string — matches WebSocket message agentId
label: 'ZETA', // displayed in the 3D HUD
color: 0xff00aa, // hex integer (0xRRGGBB)
role: 'observer', // shown under the label sprite
direction: 'east', // cardinal facing direction (north/east/south/west)
x: 12, // world-space position (horizontal)
z: 0, // world-space position (depth)
},
];
Nothing else needs to change. agents.js reads positions from x/z,
and websocket.js reads colors and labels — both derive everything from
AGENT_DEFS.
Architecture

WebSocket protocol
The backend sends JSON messages on the agents channel:
type |
Fields | Effect |
|---|---|---|
agent_state |
agentId, state |
Update agent visual state |
job_started |
agentId, jobId |
Increment job counter, pulse |
job_completed |
agentId, jobId |
Decrement job counter |
chat |
agentId, text |
Append to chat panel |
Agent states: idle (dim pulse) · active (bright pulse + fast ring spin)
