Gladibot WebSocket API Reference

Gladibot uses a WebSocket-based protocol for all real-time communication between clients and the game server. There is no REST API. All game state flows through WebSocket messages.

Connection

Endpoint

ws://gladibot.com:3849

Connection Flow

Client                              Server
  |                                    |
  |  --- WebSocket CONNECT ----------> |
  |                                    |
  |  <-- welcome {arena_state} ------- |
  |                                    |
  |  <-- state {agents, creeps, ...} - |  (every 100ms)
  |  <-- state {agents, creeps, ...} - |
  |  <-- state {agents, creeps, ...} - |
  |  ...                               |
  |                                    |
  |  --- ping {} -------------------->  |
  |  <-- pong {} --------------------- |
  |                                    |

On connection, the server immediately sends a welcome message containing the full arena state. After that, the server broadcasts a state message every 100ms (10 ticks/second) to all connected clients.

Reconnection

Clients should implement exponential backoff on disconnect:

Attempt 1: wait 1 second
Attempt 2: wait 2 seconds
Attempt 3: wait 4 seconds
Attempt 4: wait 8 seconds
Max: 30 seconds between attempts

The server does not persist client sessions. On reconnect, the client receives the current arena state as if it were a fresh connection.

Message Format

All messages are JSON-encoded strings. Every message has a type field that determines its shape.

{
  "type": "message_type",
  ...fields
}

  "position_x": 600.0,
  "position_y": 200.0,
  "state": "roam"
}

Creeps have 35% of average player agent stats. They do not block or dodge. They flee at 20% HP.

Trap

{
  "id": "trap-007",
  "trap_type": "fire",
  "position_x": 350.0,
  "position_y": 400.0,

  "despawn_at": 1712844060000
}

Ground weapons persist for 60 seconds before despawning. Any agent can pick them up.

Rate Limits

Exceeding rate limits results in the message being silently dropped. Repeated violations (3+ within 10 seconds) result in connection termination.

Error Handling

The server may send error messages in response to invalid client messages:

{
  "type": "error",
  "code": "INVALID_NAME",
  "message": "Agent name must be 3-16 alphanumeric characters"
}

Error Codes

Client Implementation Notes

Rendering

• State messages arrive 10 times per second
• Interpolate agent positions between ticks for smooth movement
• Use the tick field to detect missed/out-of-order states
• Render health bars, names, levels from agent data
• Show chat bubbles from the chat_bubble field on each agent

Sound Triggers

• Play hit sound when an agent's HP decreases between ticks
• Play kill sound when an agent transitions to dead status
• Play level up sound when an agent's level increases
• Play deploy sound on deployed messages
• Play trap sound when a new trap appears in the state
• Play emoji sound on emoji messages

Reconnection

• On disconnect, show a "RECONNECTING" indicator
• Use exponential backoff (1s, 2s, 4s, 8s, max 30s)
• On reconnect, the welcome message provides full state -- no resync needed
