DM Role Management System

[FirebrickRed]

Priority: MEDIUM
Status: TODO
Required for: #41 (Rest Commands), #47 (Character Sheet Commands)

Description

Create a system to designate who the current DM(s) are, separate from OP permissions. This allows flexible DM assignment for guest DMs, rotating DMs, or restricting DM commands without giving full OP access.

Use Cases

• Guest DMs running one-shots on your server
• Rotating DMs in West Marches campaigns
• Multiple DMs for large groups
• Restricting DM commands without giving full server OP access
• Player becomes temporary DM for a session

Commands

• /dm add <player> - Grant DM role to a player
• /dm remove <player> - Revoke DM role from a player
• /dm list - Show current DMs (with online status)

Command Examples

/dm add charlie
→ "Charlie is now a DM"

/dm remove charlie
→ "Charlie is no longer a DM"

/dm list
→ "Current DMs:
   • Astra (Online)
   • Diana (Offline)
   • [OP] ServerAdmin (Online)"

Acceptance Criteria

• /dm add <player> command (OP only)
• /dm remove <player> command (OP only)
• /dm list command (anyone can see who DMs are)
• Persistent storage in dms.yml
• Create isDM(player) helper method
• Update all DM-only commands to use isDM() check
• Tab completion for player names

Storage (dms.yml)

dms:
  - uuid-1  # Astra
  - uuid-2  # Diana

Permission Logic

isDM(player) returns true if:

• Player has OP permissions, OR
• Player's UUID is in the DM list

This way OPs always have DM access, but you can also grant DM role to non-OPs.

Commands to Update

All commands that should be DM-only need to check isDM():

• /rest commands (Issue Add /shortrest and /longrest commands #41)
• /viewsheet / /sheet commands (Issue Character Sheet Commands (View and Give) #47)
• /party commands (Issue Party Targeting System #42)
• /restoreresource / /consumeresource (Issue Add /shortrest and /longrest commands #41)
• /progresstime (Issue Time Progression Commands #44)
• Future: /npc commands, /dm commands themselves

Technical Notes

• Create DMManager class similar to CharacterSheetManager
• Create DMPersistenceLoader for loading/saving
• Add isDM(Player player) static method for permission checks
• Load DM list on plugin enable
• Save DM list on changes

Future Enhancements

• /dm session end - End session, trigger auto-save
• DM-specific chat channel
• DM notes system
