Minecraft DQN eval mode — speak on T

Eval can post AI lines into the live Minecraft server chat when you open chat with T.

Flow

minecraft dqn eval
        │
        ├─ auto step loop (like train, no gradient updates)
        │
player presses T in Minecraft client (focused window)
        │
        ├─ client controller: ui_pause=chat (bot keys released)
        │
        └─ SpeakEvalChat → bridge type=chat → Spigot ChatManager
               players see [AI] Eval mode — goal… HP… (use !ai to talk.)

Close chat with Enter or Esc → eval steps resume.

Commands (_AI)

minecraft bridge start
minecraft dqn eval
minecraft dqn eval-chat on          # default
minecraft dqn eval-chat off
minecraft dqn eval-chat status
minecraft dqn speak Ready for the next trial.
minecraft dqn status                # shows eval_chat_on_t, eval_speak_count

Requirements

Piece Need
Bridge minecraft bridge start + plugin connected
Plugin chat chat.enabled: true (default)
Window Minecraft focused so T is detected by the client controller
Permissions Players need augmentedintelligence.chat.broadcast (or owner) to see global AI lines

Notes

  • Auto-speak on T only runs in eval mode (not train), to avoid spam during learning.
  • Cooldown between auto T-speaks: ~4 seconds.
  • Manual minecraft dqn speak … works anytime the bridge is up (still uses eval chat path).
  • Bot movement is paused while chat is open so keys do not type into the chat box.
  • Server dry-run (/ai dryrun) does not block chat delivery.
