This refactors weapon/enemy combat systems to support per-weapon cooldowns,
fire modes (auto/semi), and data-driven damage rolls via ammo types. Guards
now use the pistol's stats for ranged attacks and can be stunned by non-lethal
hits. The level editor now includes a directional facing picker for newly placed
enemies and displays enemy orientation as arrows instead of dots.
Key changes:
- Logic: Replaced single weaponCooldownMs with per-weapon cooldowns map; added
prevFireHeld for semi-auto trigger-edge detection; guards now reference real
weapon definitions via rangedWeapon; projectiles carry ammoType and resolve
damage at hit time using rollDamage(); non-lethal ranged hits apply stunMs to
enemies, freezing their AI until it expires.
- Rules: Added ammoTypes array with damageMin/damageMax; weapons now specify
fireMode and ammoType (projectiles) or damage (melee); enemy definitions
include stunMs and reference weapon IDs instead of hardcoded projectile stats.
- Editor: Added FACING_DIRS constants and drawFacingPicker() overlay that lets
users click N/S/E/W neighbor cells to set a just-placed enemy's facing;
enemies now render as directional arrows showing their spawn orientation;
pendingFacingEnemy state tracks the in-progress pick across tool switches,
undo/redo, and level resets.
- View: Added GUARD_FRAME.stunned (frame 9) which takes visual priority over
all other states when e.stunMs > 0, ensuring the flinch pose displays even if
the enemy's internal state still reads 'attack' or 'chase'.
- Data: Expanded level-e1m1 to 19x21 grid with repositioned doors/enemies/exit;
bumped SAVE_VERSION to 2 since player.cooldowns and prevFireHeld are new
required fields absent from v1 saves.
- Tests: Added coverage for semi-auto trigger-edge behavior, stun application
and duration, melee non-stun behavior, damage roll range bounds, and guard
projectile ammo type/cooldown spacing; updated existing tests to use new
cooldowns/ammoType fields and toggle fireHeld for repeated shots.
Add computeRooms + alertEnemiesInPlayerRoom: a gunshot now alerts every
idle guard sharing the player's room regardless of range/LOS/cone. A
door cell is always treated as a room boundary for this purpose, even
when fully open — two rooms joined only by a doorway stay distinct
("gunfire carries through the room, not through doorways").
Fix _guardFacing side-walk/side-idle flip: was `rel > 0`, read
backwards in-game, now `rel < 0`.
Cover with three verifyWolfenstein cases: same-room alert fires,
behind-closed-door does not, through-open-door does not (door forced
slide=1 / wall zeroed to exercise the slide-independent path).
- Implement 90° field-of-view check for idle/patrolling guards (only alerts when player is within cone, in range, and has clear line of sight)
- Change patrol behavior: 0-1 waypoints ping-pong, 2+ waypoints form a one-way loop (home → nodes → home → ...)
- Reduce patrol speed to 50% of chase speed for natural movement
- Update editor to display loop closing line when 2+ patrol nodes exist
- Add new weapon sprite images (gattling, machinegun, plasma, rocket, shotgun)
- Extend map parser to support patrol route definitions via `opts.patrols`
- Add patrol routes to e1m1 (guard at 2.5,18.5) and e1m2 (guard at 9.5,8.5)
- Add comprehensive tests for vision cone (inside/outside edge cases) and patrol loop/ping-pong behavior
