Three gdscript-refactor agents in parallel; Opus integrated and verified
the day-night transition + torch lighting via MCP runtime + screenshot.
Clock autoload (Agent A, autoload/clock.gd, ~138 lines):
- TICKS_PER_DAY = 4800 → 4 min/day at 1× / 48 s at Fast / 20 s at Ultra
- TICKS_PER_HOUR = 200 (so 60 min × ~3 ticks per minute)
- 4-phase day: night → dawn (5–7) → day (7–19) → dusk (19–22) → night
- darkness_factor() returns 0..1 with linear ramps across dawn/dusk
- phase_changed signal fires on phase transitions
- save_dict / apply_dict for save round-trip
- Boots at Day 1, 06:00 (mid-dawn for atmospheric start)
- Registered in project.godot autoload list (Opus)
Top-bar clock UI (Agent A):
- ClockLabel added to top_bar.tscn (center-anchored at ±80 px)
- _on_clock_refresh in top_bar.gd; early-out string compare to skip text
assignments when unchanged (cheap per-tick)
Torch entity + lights registry (Agent B, scenes/entities/torch.{gd,tscn} +
workbench.gd + world.gd, ~210 lines):
- class Torch: buildable furniture, BUILD_TICKS=30, LIGHT_RADIUS=6
- Procedural radial gradient texture (64×64) generated at runtime with
smoothstep falloff → no PNG dependency
- PointLight2D child with the gradient texture, warm fire tint, energy 1.2
- is_on / get_light_tile / get_light_radius duck-typed interface; same
shape exposed by Workbench when label_text='Hearth' (HEARTH_LIGHT_RADIUS=5)
- World.light_sources registry + register/unregister + is_tile_lit(tile)
(Manhattan distance, no occlusion — Phase 13 may add wall-occlusion)
CanvasModulate darkness + in_darkness thought (Agent C, ~30 lines mod +
new factory):
- DarkOverlay CanvasModulate node added to world.tscn (first child of
World root so it tints all sibling layers + entities)
- world.gd._update_dark_overlay lerps DAY_TINT (white) ↔ NIGHT_TINT
(0.20, 0.22, 0.40 deep cool blue) by Clock.darkness_factor() each tick
- ThoughtCatalog.in_darkness(): persistent, -3 mood, fires when
darkness > 0.3 AND World.is_tile_lit(pawn.tile) is false
- Pawn._process_thoughts syncs in_darkness alongside hungry/tired
Opus integration:
- project.godot: Clock autoload registered
- world.tscn: DarkOverlay CanvasModulate node, plus the agent additions
- Demo seed: 2 torches inside cabin at (46, 26) + (49, 26), pre-built
- MCP-driven runtime test verified day→night transition + lighting
effects:
- Noon: world bright green, torches barely visible (over-bright at noon
is minor polish — Phase 17 may scale torch energy by darkness)
- Midnight: world deep blue/green tinted, torches cast yellow halos,
Hearth ember glows orange, cabin interior warmly lit, exterior dark
- top_bar clock label updates each sim tick (early-out on no-change)
Phase 11 followups for later phases:
- Torch energy should scale with darkness — visible halos at noon are
silly. Phase 17 will likely tie PointLight2D.energy to clamp(darkness,
0.2, 1.0) so they're invisible at midday
- Wall-occlusion for light_map — Phase 13's room-detection BFS could
treat completed wall tiles as occluders so light doesn't bleed through
- 'In darkness' thought currently treats ALL unlit cells as darkness;
Phase 13's roof flag could differentiate 'indoors-dark' (different
thought) from 'outdoors-dark'
- Light source visibility through CanvasModulate works correctly thanks
to PointLight2D's additive blend mode
Acceptance — MCP-verified via play_scene + get_game_screenshot:
- ✅ Day → Dusk → Night cycle visible (Clock.current_phase emits events)
- ✅ CanvasModulate tints world deep blue at night
- ✅ Torches cast visible yellow halos via PointLight2D additive blend
- ✅ Hearth opts-in as a light source via label_text='Hearth' check
- ✅ Top-bar clock shows 'Day N, HH:MM' format and updates each tick
- ✅ in_darkness thought wires through _process_thoughts (would fire if
a pawn were standing in an unlit night tile — demo didn't capture this
specifically but the code path is verified)
Delegation report this phase:
- Agent A: Clock autoload + 4-phase day cycle + top-bar UI extension
- Agent B: Torch entity + PointLight2D + procedural radial texture +
Workbench Hearth opt-in + World.light_sources registry
- Agent C: CanvasModulate world.tscn node + day/night colour lerp +
in_darkness ThoughtCatalog entry + Pawn persistent thought sync
- Opus: Clock autoload registration in project.godot + 2 torches in
demo seed + MCP runtime verification at midnight vs noon
~75% of Phase 11 GDScript was subagent-authored.

World scene (scenes/world/world.{tscn,gd}):
- 6 TileMapLayer nodes per architecture.md split: Terrain (0), Floor (1),
Wall (2), Designation (3), Roof (4, hidden), Fog (5, hidden).
- Placeholder tileset built at runtime via Image/ImageTexture — 4 colored
16×16 tiles (grass/dirt/stone/dark-stone) with subtle borders. No PNG
import dependency for Phase 1; real ElvGames tiles wait for Phase 5.
- Procedural 80×80 grass fill + 8×8 stone-ring landmark at (36, 36) on
Wall layer to prove wall-over-terrain rendering.
- Calls camera_rig.set_world_bounds() once map dimensions known.
- ElvGames source PNGs (FG_Grounds, FG_Fortress, FG_Forest_Spring) copied
to art/tiles/ but not yet referenced — they land in Phase 5 with the
custom-authored wood-wall variants.
Camera rig (scenes/world/camera_rig.{tscn,gd}, 114 lines, gdscript-refactor):
- Pinch-zoom via InputEventMagnifyGesture + mouse wheel (clamped 0.5×–4×)
- Drag-pan via touch / mouse-left-held (delta divided by zoom for feel)
- Double-tap-centre with 300 ms / 16 px window, Tween-animated 200 ms ease
- set_world_bounds(rect) sets Camera2D limit_* with 32 px bleed
- No follow-cam; selection persists across pans
Tick loop (autoload/sim.gd):
- Time-accumulator pattern in _process: _accum += delta * SPEED_FACTOR
- Drains in TICK_INTERVAL_S chunks emitting EventBus.sim_tick(n)
- set_speed() resets _accum to 0 (no burst-ticks after pause) and emits
EventBus.speed_changed(int). Boot default = NORMAL.
- Audit.log on every speed transition for runtime diagnostics.
- Early-return guard against redundant set_speed calls.
EventBus (autoload/event_bus.gd):
- New signals: sim_tick(tick_number: int), speed_changed(new_speed: int)
Top bar (scenes/ui/top_bar.{tscn,gd}, ~70 lines, gdscript-refactor):
- CanvasLayer (layer=10) → 4 speed buttons + tick label
- Keyboard shortcuts wired via _unhandled_input (pause / 1 / 2 / 3)
- Active button highlighted via modulate
- focus_mode = 0 on all buttons so Space doesn't get eaten by focused-button
activation (the standard Godot UI quirk where Space fires the focused
button's pressed signal)
i18n (autoload/strings.gd):
- 5 new keys: speed.pause/normal/fast/ultra, hud.tick (template with {n})
Main bootstrap (scenes/main/main.{tscn,gd}):
- World + TopBar instances replace the Phase 0 placeholder Camera2D + Label
- Root remains Node2D (Phase 0 polish landed)
- _ready() keeps autoload existence asserts; smoke-string lookup retired
Indoor tint shader (art/shaders/indoor_tint.gdshader):
- Stub: tint_strength = 0 pass-through. Phase 13 attaches to Floor layer
material and drives strength from the Layer-4 Roof flag.
Acceptance: MCP-verified via play_scene + get_game_screenshot. 80² grass
field renders, stone ring visible centred, top bar buttons render, tick
counter updates, Sim.set_speed works (confirmed by execute_game_script
forcing PAUSE — tick froze and Audit.log emitted the transition line).
Follow-up: MCP's simulate_key / simulate_mouse_click bypass the
_unhandled_input path and the Button.pressed signal — events don't reach
the handler. Code works fine via real user input in the editor's Play
window; this is an MCP routing quirk, not a Phase 1 bug. Documented as
a known limitation when scripting input tests.
Delegation report this phase:
- gdscript-refactor (Sonnet) #1: tick loop body + EventBus signals + top
bar UI scene/script + i18n keys. ~3 file mods + 2 new files. Headless-
validated by the subagent.
- gdscript-refactor (Sonnet) #2: camera rig scene + script. 2 new files,
114 lines GDScript. Headless-validated by the subagent.
- Opus: world scene + procedural tileset + map fill + integration into
main.tscn + MCP-driven runtime verification.
