Roleplay MUDs with open-source tools

Developing a technical framework for a Roleplay-Enforced (RPI) MUD requires more than just flavor text; it necessitates hard-coded systems for character validation, consent tracking, and narrative persistence. This guide outlines the implementation of a character application pipeline and an automated scene logging system to ensure lore consistency and player safety.

1

Implement the Character Application State

Create a 'pre-auth' state where new connections are restricted to a character creation area. Players must fill out fields for 'Background', 'Physical Description', and 'Roleplay Hook'. This data should be stored in a pending_approval table rather than the active character table.

apps/char_creation.py
class AppState(State):
    def on_submit(self, caller):
        db.applications.create(
            account=caller.account,
            background=caller.ndb.background,
            desc=caller.ndb.description,
            status='pending'
        )
        caller.msg('Application submitted for staff review.')

⚠ Common Pitfalls

  • •Allowing players to enter the main world before manual review
  • •Failing to enforce minimum character count limits on background fields
2

Build a Staff Review Dashboard

Develop a set of staff-only commands to list, view, and approve/reject applications. Approval should trigger the movement of data from the application table to the live character database and move the player object to the starting room.

Command: @app/list (shows pending apps)
Command: @app/view <id> (shows full text)
Command: @app/approve <id> --comment "Strong lore fit."
Command: @app/reject <id> --reason "Inconsistent with 14th century setting."

⚠ Common Pitfalls

  • •Not providing a specific 'Reason' field for rejections, leading to OOC friction
  • •Lack of notification systems when an application is processed while the player is offline
3

Configure IC and OOC Channel Logic

Hard-code the separation of communication. In-character (IC) commands like 'say' and 'emote' must be localized to the room, while out-of-character (OOC) chatter must be restricted to a global 'ooc' channel that can be toggled off to maintain immersion.

⚠ Common Pitfalls

  • •Mixing OOC names and IC names in room descriptions
  • •Allowing 'tell' commands between characters who have not met ICly
4

Implement a Consent and Limits System

Create a persistent 'limits' attribute on character objects. This allows players to set flags (e.g., @limits/combat: ask, @limits/theft: yes) that others can view before initiating high-stakes scenes. This reduces moderation overhead and ensures player comfort.

commands/social.py
def cmd_limits(caller, args):
    target = caller.search(args)
    if target:
        caller.msg(f"{target.name}'s RP Limits: {target.db.rp_limits}")

⚠ Common Pitfalls

  • •Making the system too complex to read quickly during a scene
  • •Failing to make 'Consent' a mandatory part of the onboarding tutorial
5

Automate Scene Logging

Develop a command that toggles a 'logging' state for a room. While active, every string sent to players in that room is also mirrored to a text file or database entry associated with the participants. This provides a record for lore wikis and evidence for moderation disputes.

systems/logger.py
def log_event(room, message):
    if room.db.is_logging:
        db.scene_logs.add(scene_id=room.db.current_scene_id, text=message)

⚠ Common Pitfalls

  • •Storage bloat from logging idle rooms; ensure logs auto-close after 30 minutes of inactivity
  • •Privacy concerns; ensure logs are only accessible to participants and staff
6

Integrate In-Game Lore Lookup

Create a 'lore' command that queries a structured database of world facts. This allows players to verify details (e.g., 'What is the currency of Valenthia?') without breaking character to check an external wiki.

⚠ Common Pitfalls

  • •Outdated info in the database compared to the external wiki
  • •Overwhelming players with walls of text; use categorized keywords

What you built

By codifying character entry, consent, and logging, you transform roleplay from a social agreement into a supported gameplay mechanic. This structure reduces the load on volunteer moderators and provides players with the transparency needed for a safe, immersive environment.
