Implements power level management system with tick-based power-up loop.
Players can raise PL toward max_pl (costs stamina per tick), lower PL
instantly, set exact PL targets, and cancel ongoing power-ups.
- Add Where: header with zone description
- Add Location: line with quadrant and coordinates
- Add Nearby: line showing entities in viewport (not on player's tile)
- Add Exits: line showing available cardinal directions
- Replace 'Here:' with individual entity lines showing posture
- Replace 'Portals:' with individual 'You see {name}.' lines
- Add look <thing> routing to examine command
- Add comprehensive tests for new structured output
- Update existing tests to match new output format
Player objects were removed from the players dict on quit/disconnect
but never removed from zone._contents, leaving ghost * markers on
other players' maps.
Implements a TDD-built 'use' command that lets players invoke
object verbs with optional targets:
- use X - calls X's use verb
- use X on Y - calls X's use verb with Y as args
- Proper error messages for missing objects/verbs
- Tests cover all edge cases including inventory/ground search
Also fixes type checking issue in verb dispatch where get_verb
could return None.
Implements a global examine/ex command that shows detailed descriptions
of objects. Searches inventory first, then ground at player position.
Works with Things, Containers, and Mobs.
Look command now displays portals separately from ground items.
Portals at the player's position are shown after ground items with
the format "Portals: name1, name2". This separates portals from
regular items since they serve a different purpose in gameplay.
Implements portal-based zone transitions with the enter command.
Players can enter portals at their position to move to target zones
with specified coordinates. Includes departure/arrival messaging to
nearby players and automatic look output in the destination zone.
Portals are matched by partial name or exact alias match.
Containers now display their state when viewed:
- Closed containers show "(closed)"
- Open empty containers show "(open, empty)"
- Open containers with items show "(open, containing: item1, item2)"
This applies to both ground items in the look command and inventory items.
Added _format_thing_name helper to both look.py and things.py to handle
the display formatting consistently.
Implements a module-level zone registry for looking up zones by name.
Includes register_zone() and get_zone() functions with comprehensive
tests covering single/multiple zones, unknown lookups, and overwrites.
Inventory saved as JSON list of thing template names in an inventory
column. Migration adds column to existing databases. load_player_data
returns inventory list, save_player serializes Thing names from contents.
Object.move_to() handles containment transfer: removes from old location's
contents, updates location pointer and coordinates, adds to new location.
get/drop commands use move_to to transfer Things between zone and inventory.
Supports name and alias matching for item lookup.
- Removed world module-level variable from look.py
- look.cmd_look() now uses player.location.get_viewport() instead of world.get_viewport()
- look.cmd_look() uses zone.contents_near() to find nearby entities instead of iterating global players/mobs lists
- Wrapping calculations use zone.width/height/toroidal instead of world properties
- Added type check for player.location being a Zone instance
- Removed look.world injection from server.py
- Updated all tests to remove look.world injection
- spawn_mob() and combat commands also migrated to use Zone (player.location)
- Removed orphaned code from test_mob_ai.py and test_variant_prefix.py
Removed module-level world variable and replaced all world.wrap() calls
with player.location.wrap(). Added Zone assertion for type safety,
matching the pattern in movement.py. Updated tests to remove fly.world
injection since it's no longer needed.
Movement commands now access the zone through player.location instead of
a module-level world variable. send_nearby_message uses
zone.contents_near() to find nearby entities, eliminating the need for
the global players dict and manual distance calculations.
Tests updated to create zones and add entities via location assignment.
- _find_story() now compares path.stem.lower() so "lostpig" matches "LostPig.z8"
- Server no longer writes its own prompt in IF mode (game handles prompting)
- Suppress phantom game output on restore (saved PC past sread causes garbage)
- Route .z5/.z8 files to EmbeddedIFSession now that V5+ is supported
Replaces the async _do_restore() (called after thread launch) with a
synchronous _try_restore() called before the thread starts. This
eliminates the race condition where restore mutates z-machine state
while the interpreter thread is running.
The restore prefix message is now part of start()'s return value
instead of being sent separately in play.py.
EmbeddedIFSession runs the hybrid interpreter in a daemon thread,
bridged to the async MUD loop via threading.Event synchronization.
.z3 files use the embedded path; other formats fall back to dfrotz.
- MUD ZUI components: MudScreen (buffered output), MudInputStream
(thread-safe input), MudFilesystem (quetzal saves), NullAudio
- save/restore via QuetzalWriter/QuetzalParser and :: escape commands
- state inspection: get_location_name(), get_room_objects()
- error reporting for interpreter crashes
- fix quetzal parser bit slice bug: _parse_stks used [0:3] (3 bits,
max 7 locals) instead of [0:4] (4 bits, max 15) — Zork uses 15
When starting an IF game, check for existing save file and restore
if present. Shows 'restoring saved game...' message and broadcasts
restored game state to spectators.
Also cleaned up redundant tests that didn't properly mock the
auto-save functionality now present in ::quit and stop().
- server.py: broadcast IF output to spectators after each input (skip :: escape commands)
- server.py: broadcast leave message when player exits IF mode
- play.py: broadcast game intro text when player starts a game
Spectators at the same x,y coordinates now see formatted output with
[PlayerName's terminal] header and game text.
Helper function sends messages to all players at the same x,y coordinates
as the source player, skipping the source player themselves. Used for IF
spectator broadcasting.
Phase 6: spawn command creates mobs at player position from loaded
templates. Server loads mob templates from content/mobs/ at startup,
injects world into combat/commands module, and runs process_mobs()
each game loop tick after process_combat().
Phase 3: look command now collects alive mob positions using the same
wrapping-aware relative position calc as players, and renders them as *
with the same priority as other players (after @ but before effects).
