Pre-Commit Test Checklist

Run through these checks before every commit to ensure consistent feature coverage.

Build

• cargo build succeeds with no errors
• cargo build --bin mudtool succeeds

Server Startup

• Server starts: RUST_LOG=info ./target/debug/mudserver
• World loads all rooms, NPCs, objects, races, classes (check log output)
• Database opens (or creates) successfully
• Tick engine starts and logs tick rate

Character Creation

• New player SSH → gets chargen flow (race + class selection)
• Chargen accepts both number and name input
• After chargen, player appears in spawn room with correct stats
• Player saved to DB after creation

Player Persistence

• Reconnecting player skips chargen, sees "Welcome back!"
• Room, stats, inventory, equipment all restored from DB
• Status effects do NOT persist across sessions (cleared on login)
• Verify with: sqlite3 mudserver.db "SELECT * FROM players;"

Movement & Navigation

• go north, n, south, s, etc. all work
• Invalid direction shows error
• Room view shows: NPCs (colored by attitude), objects, exits, other players
• Cannot move while in combat (combat lockout)

NPC Interaction

• examine <npc> shows description, stats, attitude label
• talk <friendly> shows greeting dialogue
• talk <hostile> shows snarl message
• Dead NPCs don't appear in room view

Combat - Tick-Based

• attack <aggressive/hostile npc> enters combat state
• Can't attack friendly/neutral NPCs
• Combat rounds resolve automatically on server ticks (not on command)
• Player receives tick-by-tick combat output (damage dealt, damage taken)
• Default combat action is "attack" if no other action queued
• defend / def sets defensive stance (reduced incoming damage next tick)
• NPC death: awards XP, shifts attitude -10, shifts faction -5
• Player death: respawns at spawn room with full HP, combat cleared
• NPCs respawn after configured time
• Combat lockout: can only attack/defend/flee/look/use/quit during combat
• flee queues escape attempt — may fail based on stats
• use <item> in combat queues item use for next tick
• Multiple ticks of combat resolve correctly without player input
• Combat ends when NPC dies (player exits combat state)
• Combat ends when player flees successfully

Combat - NPC AI

• Hostile NPCs auto-engage players who enter their room
• Aggressive NPCs do NOT auto-engage (only attackable, not initiating)
• NPC attacks resolve on tick alongside player attacks
• NPCs in combat continue attacking even if player sends no commands

Combat - RNG

• Damage varies between hits (not identical each time)
• Multiple rapid attacks produce different damage values

Items

• take <item> picks up takeable objects
• drop <item> places item in room
• equip <weapon/armor> works, old gear returns to inventory
• use <consumable> heals and removes item (immediate out of combat)
• use <consumable> in combat queues for next tick
• inventory shows equipped + bag items

Status Effects

• Poison deals damage each tick, shows message to player
• Regeneration heals each tick, shows message to player
• Status effects expire after their duration (in ticks)
• stats command shows active status effects and remaining duration
• Multiple status effects can be active simultaneously
• Status effects cleared on player death/respawn

Passive Regeneration

• Players out of combat slowly regenerate HP over ticks
• Regeneration does not occur while in combat
• HP does not exceed max_hp

Tick Engine

• Tick runs at configured interval (~2 seconds)
• Tick processes: NPC AI → combat rounds → status effects → respawns → regen
• Tick output is delivered to players promptly
• Server remains responsive to immediate commands between ticks
• Multiple players in separate combats are processed independently per tick

Attitude System

• Per-player NPC attitudes stored in DB
• examine shows attitude label per-player
• Killing NPC shifts attitude (individual -10, faction -5)
• Verify: sqlite3 mudserver.db "SELECT * FROM npc_attitudes;"

Admin System

• Non-admin can't use admin commands (gets error)
• Set admin via mudtool: mudtool players set-admin <name> true
• admin help shows admin command list
• admin promote <player> grants admin (verify in DB)
• admin demote <player> revokes admin
• admin kick <player> disconnects target player
• admin teleport <room_id> warps to room (shows room list on invalid)
• admin registration off blocks new player creation
• admin registration on re-enables it
• admin announce <msg> broadcasts to all players
• admin heal heals self; admin heal <player> heals target
• admin info <player> shows detailed stats + attitudes
• admin setattitude <player> <npc> <value> modifies attitude
• admin list shows all players with online/offline status

Registration Gate

• With registration open (default), new players can create characters
• With registration off, new SSH connections get rejection message
• Existing players can still log in when registration is closed

MUD Tool - CLI

• mudtool players list shows all players
• mudtool players show <name> shows details
• mudtool players set-admin <name> true works
• mudtool players delete <name> removes player + attitudes
• mudtool settings list shows settings
• mudtool settings set registration_open false works
• mudtool attitudes list <player> shows attitudes
• mudtool attitudes set <player> <npc> <value> works

MUD Tool - TUI

• mudtool tui launches interactive interface
• Tab/1/2/3 switches between Players, Settings, Attitudes tabs
• Arrow keys navigate rows
• 'a' toggles admin on Players tab
• 'd' prompts delete confirmation on Players tab
• Enter edits value on Settings and Attitudes tabs
• ←→ switches player on Attitudes tab
• 'q' exits TUI
