Introduce active diplomacy where rival leaders approach the player with
requests, demands, trades, and gifts rather than passively waiting.
New CivilizationDiplomacy.js module handles:
- 9 request kinds (joinWar, breakTreaty, borderUltimatum, demandGold,
demandTech, techTrade, ceasefire, peace, alliance) with initiative
tiers so urgent calls to arms aren't drowned out by filler offers
- Cooldowns per (leader, target, kind) plus a per-leader gap so a
leader can't spam different requests to bypass rate limits
- Frustration grudge (0-100) raised by refusals, decaying each turn
and dragging attitude toward hostility through the ordinary war path
- Escalation: frustrated leaders demand compensation, then renounce
treaties at breaking point, with ordinary hostility finishing the job
- Border ultimatum promises checked when pledges expire (double penalty
for broken word)
- Unprompted gold/tech gifts from leaders with high attitude
- Staleness validation so requests the world invalidated are dropped
- AI-to-AI requests resolve immediately through the same pipeline
UI changes:
- AI requests queued on state.pendingRequests, presented via audience
popup at the start of the human turn (one per turn, configurable)
- Diplomacy screen shows ACCEPT/REFUSE with consequence hints until
answered; unanswered requests lapse with half-weight penalties
- New event types: treatyRenounced, pledgeBroken/pledgeKept, aiGift
- Leader dialogue for demands, refusals, gifts, and renouncements
- Tetris Attack menu gets a title art backdrop
Data/infra:
- diplomacyRequests tuning in civilization-rules.json (thresholds,
cooldowns, attitude weights, per-request config)
- Frustration, requestCooldown, lastRequestTurn, pledges fields on
civ state — all backward-compatible with old saves
- Full verification suite covering eligibility, resolution, cooldowns,
frustration arc, serialization, and fuzz testing
- Implement per-character voice clip system (match, supermatch, win, lose) that
loads lazily per round and falls back gracefully when clips are missing
- Queue voices to play after arcade cues, with intelligent interruption handling
so only one line plays at a time
- Rename ensureRoundBackgrounds to ensureRoundAssets to handle both images and audio
- Reduce background music volume from 0.8 to 0.4
- Update character sprite sheet and document voice clip structure in sprites.md
Refactor Stage Clear narrative from battling opponents to helping friends.
Update character poses: friends cheer on clears and fret during danger.
Implement multi-line intro cutscenes with step-by-step progression and random background art.
Switch dialog to randomized arrays (introLines, winLines, loseLines).
Add new sound effects for Beth and Jerry.
Update validation and documentation to match new data structure.
Introduce temporary emotional reactions for the host portrait that hold
for a duration before reverting to a resting pose. The setPose method
now accepts an optional holdMs parameter; when provided, the pose is
applied temporarily and transitions back to the base (danger-driven)
pose once the timer elapses. This prevents the host from remaining in
a reaction pose indefinitely after events like scoring or opponent
clears.
Detect when a player shortcuts across geometry and skips checkpoint gates
by monitoring the spline projection delta. When the player jumps past
the configured skip threshold, they are teleported back to the last
legitimate checkpoint, shown a blinking "CHECKPOINT MISSED" banner,
and given a brief invulnerability window.
- Add checkpointMissSkip and checkpointMissMs config values
- Implement delta-based gate-skipping detection in kart logic
- Add HUD banner and sound feedback for missed checkpoints
- Make player sprite blink during the correction window
- Add verification tests for detection, correction, and clean-race false positives
- Make Tetris Attack portrait frame half-transparent
Restructure Tetris Attack Stage Clear from "clear all target panels" to a
multi-stage round system with a sliding boundary line.
Gameplay changes:
- Each character now has 5 stages instead of a single match
- A CLEAR line appears after a set number of rows rise, then rides the
stack upward; the objective is to clear everything above it
- Clearing a stage advances to the next: same board, faster speed, fresh line
- Stage progress is saved to localStorage; characters unlock sequentially
- Added a stage select screen with progress squares per character
Logic changes:
- Replaced `targetsTotal` with `clearLine` tracking and `countAboveLine`
- Added `advanceStage()` to resume play on the same stack one speed level higher
- Win condition now checks `countAboveLine() === 0` instead of target count
- Removed `target` flag from panels; panels below the line are irrelevant
- Continuous speed ramp via fractional `speed` per stage
UI changes:
- Clear line drawn as a pulsing bar with "◀ CLEAR" label outside the board
- "CLEAR LINE!" announcement on appearance, "STAGE N CLEAR!" banner on win
- HUD shows stage number instead of panel count
- Game over offers "Retry Stage", "Stage Select", or "Menu"
Asset changes:
- Backgrounds renamed to `background-{hero}-r{stage}.png` (5 per character)
- Lazy-load backgrounds per round instead of preloading all 30 images
- Updated tetrisattack.json with `stagesPerRound`, `stageSpeedStep`, and
per-character `clearLineRows`
Tests:
- Rewrote stage clear soak tests for the new mechanic
- Added stage round progression, speed ramp, and board preservation tests
Implement the full Tetris Attack clone with three game modes:
- Endless: clear panels as the stack rises, speed increases with levels
- Stage Clear: defeat 6 character opponents (Beth, Jerry, Michael, Steve, Victor, Klaxon) in sequence
- Puzzle: solve 24 pre-vetted puzzles within move limits
Core engine (src/games/tetrisattack/TetrisAttackLogic.js) is a pure, deterministic
state machine with match detection, chain propagation, gravity, and scoring tables
matching the SNES original. Includes a headless verifier (verifyTetrisAttack.js)
testing match detection, chains, gravity invariants, top-out, puzzle solvability,
and seeded determinism.
Art is fully optional via drop-in spritesheets (spec: sprites.md); procedural
fallbacks draw 16-bit-style panel icons with distinct shapes for colorblind access.
Puzzle bank generated by genTetrisAttackPuzzles.js and verified as solvable within
optimal move counts.
Shared nintendo soundtrack reused via soundtrack overrides.
