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 three new entities:
- Rocket Trooper: anti-armor infantry with shoulder-mounted guided rocket
- Constructor: unarmed tracked builder to replace lost commander build capacity
- Advanced Vehicle Plant: 4×4 factory with doubled production bays
Update AI composition weights and counter logic for the new units. Fix
byDef map to use Object.create(null) so the "constructor" key doesn't
shadow Object.prototype.constructor and silently poison gap calculations.
Add procedural art shapes for all three, register proc shapes in TARules,
update sprite frame assignments, and add core-structures assets.
