- Add HP text readout to battle animations showing 1-10 scale HP
(matching Advance Wars' classic HP display), with smooth tweening
- Extract cursor drawing into procedural texture, keeping it independent
of the UI sheet
- Add advancewars-ui.png sprite sheet and update artwork config
Introduce a new battle background spritesheet (advancewars-battlebg) that
displays context-appropriate backdrops behind each fighter during battle
cut-ins. The backdrop is selected based on the terrain/building type the
fighter is standing on (city, base, airport, port, plain, wood, mountain,
sea, reef, shoal, river, bridge, road, hq).
- Add battleBgSheet to artwork.json and asset manifest
- Implement playBattleAnim() backdrop system with terrain lookup
- Provide procedural fallback matching the real sheet's frame map for
art-free playability
- Mirror defender backdrops to match mirrored defender sprites
- Document the 14-frame sheet spec in sprites.md (256×256 cells, 5 cols)
Introduce a unit unlock system that progressively grants access to new
unit types as the player advances through the campaign. Each mission
specifies which units each army can build, starting with basic units
and unlocking MD Tanks, Rockets, Anti-Air, Missiles, Lander, Cruiser,
and eventually the full armory.
- Add unit sprite sheet (advancewars-units.png) and artwork config
- Implement unlock validation in production and build options
- Add tutorial dialogue from Ethel explaining new mechanics and units
- Balance AI difficulty by reducing skill levels and aggression
- Adjust capture weights for more balanced AI behavior
- Add introductory city capture mechanic in first mission
- Update verification tool to support unlockedUnits
Implement a full Advance Wars clone with campaign (20 missions) and
War Room skirmish mode. Includes:
- Headless game engine (AdvanceWarsLogic) with complete AW1 rules:
terrain movement, combat, capture, production, transports, fuel,
fog of war, CO powers, and multiple objective types
- AI opponent (skill 1-5, aggression/capture tuning) with BFS
pathfinding, threat evaluation, production counter-tables, and
fog trap awareness
- Canvas-rendered map view with procedural stand-ins that can be
replaced by drop-in painted spritesheets (no code changes)
- 11 playable COs with unique day-to-day modifiers and powers
(Hyper Repair, Lightning Strike, Tsunami, Meteor Strike, etc.)
- Campaign briefings with typewriter text and opponent portraits
- Comprehensive headless verification suite (rules, combat formula,
pathfinding, economy, capture, fog, CO powers, soak tests)
- New assets: terrain/building sheets, adventure music tracks,
game icon frame 86
- Refactor SpireClimb and SWDBG to use the shared soundtrack service
