- Add `flight` blocks to Fighter, Bomber, and Hover Constructor in rules JSON
defining height, takeoff time, and landing time
- Implement purely cosmetic altitude system: units ease upward when given
orders and settle back down when idle, using smoothstep easing
- Shadow stays pinned to ground position, fades in and shrinks as altitude
increases — the gap between body and shadow sells the height
- Health/build bars move with the lifted body; selection ring stays on ground
- Add production dials (progress pies) on the player's own factories:
top-left shows whole queue progress, top-right shows unit on the bench
- Pass real delta time to render() for framerate-independent takeoff animation
- Update sprites.md with flight system docs and art implications
- Add stub scene support and comprehensive verification tests
Introduce a two-layer domain system (ground/air) that separates units into
independent simulation layers. Air units ignore the nav grid, never collide
with ground units, and can only be targeted by weapons listing "air" in their
targets. Hover units gain water-crossing ability via the move class cost table.
New content:
- Fighter (air interceptor with AA cannons)
- Bomber (ground-attack aircraft with bomb rack)
- Hover Constructor (water-crossing builder)
- Airfield (produces all three air units)
AI gains air superiority management: interceptors hunt enemy aircraft instead
of joining ground pushes, and the production mix auto-counters observed enemy
air. Ground anti-air (rocket troopers/tanks) also gain targeting weight.
Rendering adds a dedicated depth band for aircraft above all ground actors,
plus a displaced shadow sprite for altitude perception. HUD tooltips display
domain and weapon targeting information.
Validation ensures domain/moveClass agreement, requires at least one anti-air
weapon when air units exist, and excludes air classes from corridor generation.
Comprehensive test fixtures cover domain separation, collision, splash, and
order handling.
Idle builder units now automatically repair damaged allied structures
and units within their build range. A priority system ensures defensive
buildings are repaired before factories and other buildings. Auto-heal
orders are marked as non-player-assigned so explicit player orders
always take precedence. Builders can re-prioritize targets on a
retargeting cadence, similar to combat target acquisition.
Includes visual asset updates for TA arm and core units/structures.
Adjusts test to isolate passive self-heal from the new auto-heal mechanic.
- Introduce configurable victory modes: "commander" (default, kill enemy commander) and
"annihilation" (fight until army can no longer produce)
- Add Laser Tower (1x1, hitscan) and Missile Launcher (2x2, guided with min-range dead zone)
as buildable defensive structures with new towerlaser and towermissile weapons
- Units now hold at weapon range when attacking buildings instead of closing to point-blank,
controlled by new engageHoldFraction constant (0.45)
- Replace center-to-center distance with surface distance for building targets; buildings are
treated as rectangles with true half-extents, improving combat accuracy
- Buildings (towers) now freely traverse and aim in all directions regardless of art orientation
- Commander unit flagged with isCommander; victory conditions validate presence of commanders
- Update campaign missions to use destroyCommander objective; reseed m02 (old seed unwinnable
after combat balance changes)
- Add skirmish setup UI for selecting victory conditions
- Update AI skill ladder verification thresholds to account for engage hold behavior
- Add comprehensive tests for victory conditions and defensive structures
Allow builders to repair damaged friendly units and buildings by
right-clicking them. Repair cost and duration are proportional to the
damage healed (X% HP restoration costs X% of build cost and takes X%
of build time).
Key changes:
- New 'repair' order type with validation (own units only, must be
damaged, requires a builder)
- Separate _repairPower accumulator so repairing a damaged factory
doesn't silently speed up its production queue
- Repair drains energy/mass through the same economy machinery as
construction, including brownout throttling
- HUD hints guide players to right-click damaged allies to repair
- Repair order auto-clears when complete; unqueued orders interrupt it
while queued orders wait behind it
- Visual waypoint color for repair orders
- Comprehensive test coverage in verifyTotalAnnihilation.js
- Initialize lastDamagedTick to -1e9 for fresh units (finite sentinel to avoid JSON.stringify null)
- Add lastDamagedTick to serialize/deserialize so the pause timer persists across save/load
- Add comprehensive tests for self-heal behavior:
- Rate verification (~33% max HP/min)
- 30s pause after damage and clock restart on new hits
- Sustained fire suppression
- No overhealing
- Non-selfHeal units don't regenerate
- Damage clock survives save/load round-trip
- Queue multiple orders per unit by holding CTRL (matching original game)
- Draw colored waypoint chains on the minimap/world for each queued order
- Display queued order count in selection detail panel
- Limit queue overlay to MAX_QUEUE_LINES to avoid clutter in large selections
- Use distinct colors per order type (move, attack, patrol, build, etc.)
- Update hint text and placement UI to mention queueing behavior
- Add verification tests for queue append/replace semantics, consumption order,
and queued build orders
