Blackfire - GMCP

Blackfire sends structured game data over GMCP (telnet option 201) beside the text of the game, for client scripts and panels such as Mudlet's. Every message is Package.Name followed by JSON.

Packages

Package	What it carries
`Char.Vitals`	Health, mana and movement (as strings), with every prompt
`Char.Status`	Name, level, class, race, alignment and position
`Char.Affects`	The spells and skills affecting you, with their durations
`Room.Info`	The room's number, name, area, exits and features
`Room.AddPlayer`, `Room.RemovePlayer`	Players arriving and leaving
`Comm.Channel.Text`	Channel messages: says, tells, gossip and the rest
`Char.Quests`	Your quests and their objectives (ask for it, below)
`Char.Achievements`	Your achievements and progress towards them (ask for it, below)

Quests and achievements

The quest packages are sent only to clients that ask for them. Send this once GMCP is on (in Mudlet, from a script):

Core.Supports.Add ["Char.Quests 1", "Char.Achievements 1"]

In Mudlet: sendGMCP([[Core.Supports.Add ["Char.Quests 1", "Char.Achievements 1"] ]]). Core.Supports.Remove ["Char.Quests"] stops them again.

You are then sent Char.Quests.List with every quest you have started, and again each time you enter the game:

{"quests": [
  {"id": 1, "title": "First Steps", "status": "completed",
   "completed": "2026-10-17T12:00:00Z"},
  {"id": 2, "title": "Finding Your Way", "status": "active",
   "objective": "Type GUIDE to ask the way to the bank.",
   "goals": [{"text": "Use the guide command", "done": 0, "needed": 1}]}
]}

After that, Char.Quests.Update sends one quest, in the same form, whenever it changes: when it starts, when a goal counts, when a step is done and when it is completed. A quest you no longer have is sent as {"id": 2, "status": "removed"}. Keep the list by id and replace entries as updates arrive.

status is active or completed.
objective is what the quest asks of you now, as JOURNAL shows it.
goals lists what the current step needs, with how much of each is done. A step that asks for a level ends with a goal such as Reach level 10, whose done is your level.
completed is when you completed it, in UTC.
description and objective are left out when empty, and goals once a quest is completed.

Char.Achievements.List and Char.Achievements.Update work the same way, with the list under achievements. They cover every achievement you can earn: active ones carry their goals, and earned ones are completed.

The web client shows both in its side panel.
