ElytraFlightComponent.setFlying(true) was never called, so the ElytraPhysicsSystem and RingCollisionSystem skipped all player entities. Now activateElytraFlight() is called after teleport and race kit equip to enable flight for each player.
RingCollisionSystem now accepts a GameHudManager and calls showRingPassed() when a player flies through a ring. GameEntityFactory.createPlayerEntity() now adds a RingEffectComponent so ring effects (boost/slow) are processed. RingEffectSystem is registered in GameOrchestrator after RingCollisionSystem.
MinestomGamePhase now tracks elapsed ticks and finishes when the configurable race duration expires (default 5 min / 6000 ticks) or when all players have passed every ring on the active map. Also accepts an onGamePhaseFinished callback for map transition wiring.
GamePhaseFactory now accepts an onGamePhaseFinished callback that is passed to MinestomGamePhase. GameOrchestrator wires advanceToNextMap() as the callback so that when a race ends (duration or all rings), the next map loads automatically. When the cup is complete, the phase series naturally advances to MinestomEndPhase.
MinestomEndPhase now reads scores from ScoreComponent via the EntityManager, applies position bonuses (1st:50, 2nd:30, 3rd:20, rest:10), and displays a ranked scoreboard as title + chat message. This makes ScoreComponent the single source of truth for scoring during gameplay, eliminating the duplication with ScoringServiceImpl.
RingVisualizationSystem spawns a circle of particles at each ring position once per second so players can see where to fly. Different ring types use different particles: END_ROD (standard), FLAME (boost), COMPOSTER (checkpoint), SNOWFLAKE (slow), ENCHANT (bonus). The system operates on the game entity's ActiveMapComponent and broadcasts packets to all online players.
Minestom does not fire a native firework boost event. PlayerEventHandler now listens for PlayerUseItemEvent, checks if the player is holding a FIREWORK_ROCKET while flying elytra, applies ElytraPhysics.applyFireworkBoost() to their velocity, and consumes one rocket from the stack. The ECS EntityManager is wired into the event handler via VoyagerServer.
…ramework Complete rewrite of the game psychologist agent based on academic research (SDT, Flow Theory, Hook Model, Operant Conditioning, Kahneman/Tversky, Duolingo streak data). Adds the VOYAGER Psychology Checklist, 9-step feature review framework, Bartle player type analysis, concrete numeric thresholds, sound design specifications, onboarding protocol, and hard ethical boundaries. Adds supporting research document 004-game-psychologist-agent-research.md.
…lta and applying look-direction impulse
Registers a dev-only command that skips the lobby countdown and immediately loads the first available map. Only active when the server is started with -Dvoyager.dev=true (set automatically by the :server:runServerDev Gradle task).
startGame() creates player entities only for players online at that moment. When the server auto-starts the game at boot (no players yet), any player joining later has no ECS entity — activateElytraFlight() found nothing and the firework boost check returned early (flight == null). Now creates the entity on-demand when no existing entity is found.
…map config - Fix unit bug: player.setVelocity() expects blocks/second; previous code passed blocks/tick (1/20th of needed magnitude) causing the 'braking' feel - Change boost direction: yaw-only (pitch ignored) + fixed upward angle (25°) so players always gain height regardless of look direction - Sustain boost for 20 ticks via scheduler instead of single packet so the client's elytra physics registers the impulse across multiple frames - Add BoostConfig record with speedBlocksPerTick, upAngleDeg, durationTicks, cooldownMs — defaults to 2.5 b/t, 25°, 20 ticks, 3s cooldown - Thread BoostConfig through MapDefinition → GameOrchestrator.loadNextMap() → PlayerEventHandler.setBoostConfig() for per-map tuning - Add 3-second cooldown to prevent back-to-back boost spam
…oldown, 30-tick duration Per game design spec: - 3 firework rockets per map (refilled at each map start via equipForRace) - 4-second cooldown between boosts (prevents chain-boost spam) - 30-tick boost duration (1.5 s — matches vanilla firework feel) - Rockets consumed from hotbar slot on each use BoostConfig.DEFAULT updated accordingly; per-map overrides remain possible.
…ed angle Remove upAngleDeg from BoostConfig — direction is now derived entirely from the player's current pitch and yaw at the moment of activation. lookX = -sin(yaw) * cos(pitch) lookY = -sin(pitch) // pitch < 0 = looking up → positive Y lookZ = cos(yaw) * cos(pitch) Players control the boost trajectory by where they look: up to climb, level to sprint, or down to dive. No fixed upward component is imposed.
Sending setVelocity() every tick for 30 ticks locked the player into a fixed trajectory and fought the client's own elytra steering. Replace with a single one-shot velocity impulse; the vanilla client's elytra physics then handles drag, gravity, and directional control naturally from that starting speed. Remove durationTicks from BoostConfig — no longer meaningful for a one-shot boost.
Ring collision now only checks the next expected ring in sequence — players must fly through portals in order instead of being able to skip ahead. Replaces the random-order loop with a single passedCount() index check. Also sets chunk and entity view distance to maximum (32) before server init so players see the full course at all times during elytra flight. Updates RingCollisionSystemTest and GameOrchestratorTest to match the new sequential enforcement and 3-arg GameOrchestrator constructor.
- Replace custom lastBoostTime check with SetCooldownPacket so the firework rocket greys out in the hotbar for the cooldown duration (vanilla UX) - Keep a lightweight server-side guard against race-condition double-fires - Remove rocket consumption — rockets are infinite (never leave the slot) - Give 1 rocket on equip instead of 3 (count irrelevant when infinite)
Adds OutOfBoundsSystem that teleports a player back to the current map's spawn position when they fly below Y=-64 (void), above Y=320 (world ceiling), or land on the ground after having been airborne for at least 1 second (20 ticks). A 40-tick cooldown after each reset suppresses the landing check while the player is standing at spawn before re-activating their elytra. Out-of-bounds checks are always active regardless of cooldown. The system is registered in GameOrchestrator between ring collision and ring effects. Velocity and previous-position tracking are cleared on reset to prevent physics artifacts on the next tick.
Add BoostConfigDTO to shared/common so per-map boost values can be stored
in the existing map.json file alongside portals:
{"boostConfig": {"speedBlocksPerTick": 3.0, "cooldownMs": 2000}}
Both fields are optional — Gson leaves absent fields as null, and CupLoader
falls back field-by-field to BoostConfig.DEFAULT so old JSON files continue
to work without any changes.
Previously dev-start called loadNextMap() only — the phase series stayed in Lobby, so MinestomGamePhase.onUpdate() never ran, entityManager.update() was never called, and ring collision / scoring never worked. Now calls skipLobbyToGame(): loads map then calls phaseSeries.advance() to transition Lobby → Game so the ECS game loop ticks every server tick and rings, scoring and HUD all function correctly.
Each phase now guards its finish() with a boolean flag so it can only complete once. This prevents the double-advance crash that occurs when: - skipLobbyToGame() manually advances the series while the lobby timer is still ticking - any phase's finish() is called more than once in the same tick MinestomEndPhase.onFinish() now schedules stopCleanly() for the next tick instead of calling it synchronously. This ensures the finish() → advance() chain in Xerus completes before the server shuts down, fixing: IllegalStateException: Advance called on not running phase! The finishing flag is reset to false in onStart() so phases can be restarted cleanly if needed.
- Reset ScoreComponent and RingTrackerComponent for all player entities
at the start of each map load so points don't carry over between maps
- Add SplineVisualizationSystem: merges ring centers and guide points,
computes Catmull-Rom spline via SplineAPI, renders ENCHANTED_HIT
particles every second along the ideal racing line
- Load guide points from GuidePointStore (data/maps/{world}/guides.json)
into MapDefinition via CupLoader (dataPath now passed to CupLoader)
…n, spline visibility - Schedule ECS state resets and teleports on Minestom tick thread (not ForkJoinPool) to fix concurrent HashMap corruption and unreliable reset - Guard skipLobbyToGame() to only advance phase when in LobbyPhase, preventing double-call from pushing phase to End prematurely - Throttle ScoreDisplaySystem to 4-tick intervals with change detection to eliminate actionbar flickering (was sending every tick at 20 TPS) - Read world spawn from level.dat NBT (SpawnX/Y/Z) via AnvilLoader so players teleport to the map's actual world spawn, not first ring center - Improve spline particles: END_ROD particle, 24 pts/segment, 4 Hz refresh rate, count=3 with 0.1 offset spread for visible racing line
- Rewrite skipLobbyToGame() to call lobbyPhase.finish() instead of manually calling loadNextMap() + phaseSeries.advance(): normal finish path cancels the timer task before advancing to Game, eliminating the double-phase where the lobby countdown kept firing after dev-start - Add restartGame() for non-lobby states: clears callbacks before stopping the current phase (no side effects), removes player entities, resets cup progress, recreates a fresh phase series, starts+finishes the new lobby via the normal path - Remove buildTask wrapper from loadNextMap() so the CompletableFuture resolves after reset+teleport are initiated, not before - Add setOnGamePhaseFinished() setter to MinestomGamePhase so restartGame can clear the callback before stopping the phase cleanly - Add suppressOnFinish flag to MinestomEndPhase to prevent stopCleanly during a dev restart - Add CupProgressComponent.reset() to restore cup to first map
Move per-player reset from a bulk pre-teleport loop into activateElytraFlight() so that ScoreComponent and RingTrackerComponent are cleared at the exact moment a player is teleported to the map start position, not before entities may exist.
… spec - Add codename persona to all 23 agents (Atlas, Forge, Pulse, Scribe, ...) - Add Peer Network section with dual-identifier cross-references - Restrict tools per role: read-only agents lose Edit/Write/Bash - Add Security guardrails block against prompt injection - Add color grouping for UI differentiation - Enable project-scoped memory for Scout, Scribe, Lumen - Add "Proactively..." phrasing for 6 auto-delegation candidates - Set isolation: worktree for Loom, Anvil, Spark - Update CLAUDE.md team table with codenames - Add docs/guides/agent-team.md
Firework boost logic moved from PlayerEventHandler (Netty I/O thread) into FireworkBoostComponent + FireworkBoostSystem (tick thread). Cooldown tracking, impulse math, and SetCooldownPacket sending now run inside the ECS per-tick loop. HUD management migrated from the parallel GameHudManager/GameHud registry into HudComponent, attached to every player entity via GameEntityFactory. RingCollisionSystem no longer takes GameHudManager as a constructor parameter — it reads HudComponent directly from the processed entity. ScoreDisplaySystem routes actionbar updates through HudComponent.updateActionbar() to eliminate duplicated formatting logic. GameHud and GameHudManager are now dead code pending deletion. Adds tests for FireworkBoostComponent (8), FireworkBoostSystem (5), and HudComponent (4). Adds ADRs, reference docs, how-to guide, and research papers for both migrations.
…ounter Tick-based cooldown counting diverges from the client-side item cooldown visual (SetCooldownPacket) under server lag: the server counted ticks, the client counted real elapsed time. With wall-clock enforcement the server allows another boost at the same real-world moment the client visual clears. FireworkBoostComponent.cooldownRemainingTicks replaced by cooldownExpiryMs (System.currentTimeMillis() + cooldownMs). isOnCooldown() compares current time against the deadline; getCooldownRemainingTicks() derives the value dynamically for packet construction. FireworkBoostSystem no longer calls tickCooldown(). Tests updated to reflect wall-clock semantics.
The old setVelocity() overwrite locked the player into the activation direction for ~1 second (elytra steering needs 22+ ticks to redirect a large impulse). The new model replicates vanilla firework behaviour: Attack (1 tick): additive kick in look direction — preserves existing velocity so a banking turn stays banked. Sustain (burnDurationTicks ticks): per-tick additive thrust that re-reads look direction each tick, so players can steer mid-boost. Thrust fades linearly from 100% to 30% over the burn window. Velocity is capped by magnitude (not per-axis) to prevent diagonal overshoots. Defaults (tuned from research, game-designer spec): kick = 0.5 b/t (10 m/s) burnDuration = 24 ticks (1.2 s) thrustPerTick = 0.035 b/t (0.7 m/s) maxSpeed = 2.75 b/t (55 m/s) cooldown = 4 000 ms BoostConfig gains 3 new fields; BoostConfigDTO and CupLoader updated. Burn is cancelled on teleport-to-start. Tests updated.
The previous kick (0.5 b/t additive) + thrust (0.035 b/t per tick with falloff) approach felt wrong because the values were far smaller than vanilla. The correct formula from the decompiled source (docs/elytra-physics-reference.md §3.2) is: newVel = 0.5 × currentVel + 0.85 × lookDirection Applied each burn tick (re-reading look so players can steer mid-boost). From rest this gives 0.85 b/t immediately and converges to ~1.7 b/t steady state after ~5 ticks. Changes: - BoostConfig: remove kickBlocksPerTick and thrustBlocksPerTick (baked into formula); update DEFAULT maxSpeedBlocksPerTick to 3.5 b/t (2× steady state headroom) - BoostConfigDTO: remove the two dropped fields - CupLoader: update convertBoostConfig() field-by-field fallback - FireworkBoostSystem: activation (Phase 1) runs before formula (Phase 2) in the same tick so the player feels the impulse on the exact frame they press boost - Tests: update constructor calls and rename/redesign assertions to match new behaviour
…rifting Root cause: ElytraPhysicsSystem imported ElytraPhysics but never called computeNextVelocity() — the server had no physics authority. The client ran its own elytra simulation freely, and without server-side direction alignment and drag, the player experienced uncontrolled drifting between boosts. Changes: - ElytraPhysicsSystem: call ElytraPhysics.computeNextVelocity() each tick and push the result to the client via player.setVelocity(). The server is now authoritative for elytra physics (matches vanilla architecture). - FireworkBoostSystem: delegate to ElytraPhysics.applyFireworkBoost() instead of the inlined formula; remove the now-redundant lookVec() helper. - RingCollisionSystem: switch from 'currentPos - velocity' to flight.getPreviousPosition() for the ring segment; velocity is now server-tracked (not position delta), so direct position storage is correct. Added null guard for the first tick after teleport. - GameOrchestrator: reorder systems — RingCollisionSystem runs before ElytraPhysicsSystem so it reads the previous tick's position before it is overwritten by the physics update. Reset flight.velocity and previousPosition to zero/null in activateElytraFlight() so each map starts from a clean state. - Tests: enable ElytraPhysicsSystemTest (all four tests now pass with server-side physics); update RingCollisionSystemTest to use setPreviousPosition instead of setVelocity; add null-previousPosition guard test.
…only on external forces Remove the per-tick player.setVelocity() call from ElytraPhysicsSystem — vanilla elytra flight is client-authoritative and pushing velocity every tick caused constant client-side reconciliation (drifting feel). The server now tracks velocity internally for boost/ring formulas without overriding the client simulation. Velocity is sent to the client only for external forces: - RingEffectSystem sends updated velocity when a BOOST or SLOW ring changes it - OutOfBoundsSystem sends Vec.ZERO on respawn/teleport to halt the client
Documents the mandatory code patterns derived from ManisGame: sealed interface hierarchy, factory utility classes, provider/registry pattern, record components, @NotNullByDefault, enum DSL pattern, functional Creator interfaces, Gson adapter naming, exception hierarchy, and module API boundary rules. Also documents ArchUnit enforcement in server arch tests.
…odule boundaries Adds ArchUnit 1.3.0 to the version catalog and three test classes: - EcsArchitectureTest: enforces *Component and *System naming conventions - LayerArchitectureTest: verifies server module does not import org.bukkit.* - NamingConventionTest: checks package and class naming rules Rules are derived from the ManisGame reference and the CLAUDE.md module isolation invariant.
…ot-reload task Adds ArchUnit JUnit5 test dependency (wires the version catalog entry from prior commit). Adds two local-dev Gradle tasks: - runServerDebug: starts the server with JDWP on port 5005 (configurable via -PdebugPort) for IDE debugger attachment and method-body hot-swap (plain OpenJDK). - runServerHotswap: starts the server under JBR 25 + HotswapAgent 2.0.3 for structural hot-reload (new methods, fields, classes) without server restart. First run downloads JBR 25 via Foojay (~200 MB). Agent JAR resolved via isolated hotswapAgent configuration.
Add Hibernate/MariaDB runtimeOnly deps to server, Mockito to test scope, JUnit to shared/database tests. Stage portal DTO and database service refactors from in-progress sprint work.
- build.yml: split build/test steps, JaCoCo on all 3 OS, fix cache-read-only branch ref (main not master) - release.yml: confirmed main trigger correct, remove duplicate shadowJar steps (already handled by .releaserc.json) - Add PR template with Conventional Commits checklist - Add voyager-project-manager (Flightplan) Scrumban agent - Update CLAUDE.md with ManisGame design rules and Flightplan entry - Update elytra-physics-reference.md with client authority model

The string matched GitGuard's secret pattern. Replaced with a clearly named test placeholder that carries no ambiguity.
areNotAbstract() does not exist in ArchUnit 1.3.0; the equivalent API is doNotHaveModifier(JavaModifier.ABSTRACT).
GitGuard flagged the literal dev password stored as a public constant. Password has no safe default — removed the constant and set the fromEnvironment() fallback to empty string, requiring VOYAGER_DB_PASSWORD to be set explicitly. The local Docker Compose password is documented in docker/mariadb/compose.yml.
beFinal() does not exist on ClassesShould in ArchUnit 1.3.0; the correct API is haveModifier(JavaModifier.FINAL).
…ArchUnit scope - Remove `sealed`/`permits` from ElytraPlayerRepository and GameResultRepository so Mockito can generate subclass mocks for service unit tests (Category 1, 9 failures) - Add `instance.loadChunk(0, 0).join()` before every `env.createPlayer()` call in HudComponentTest (4), ElytraPhysicsSystemTest (3), FireworkBoostSystemTest (9), RingEffectSystemTest (2), and pre-load the chunk range in EcsGameLoopLoadTest (1) so the Minestom test environment has a loaded chunk before spawning players (Category 2, 25 failures) - Add ImportOption.DoNotIncludeJars.class to @AnalyzeClasses on EcsArchitectureTest, LayerArchitectureTest, and NamingConventionTest to prevent false-positive violations from scanned JAR dependencies on the test classpath (Category 3, 7 failures)
…failures
- Add systemProperty("minestom.inside-test", "true") to server test task.
Minestom 2026.03.25 asserts this flag in ConnectionManager.createPlayer()
before allowing player spawning; without it all env.createPlayer() calls
throw a bare AssertionError regardless of chunk-loading state.
- Remove DoNotIncludeJars from all three ArchUnit @AnalyzeClasses annotations.
The option was incorrectly excluding shared-module JARs from the scan,
leaving an empty class set for every rule.
- Add archunit.properties with allowEmptyShould=true.
ArchUnit 1.3.0 bundles ASM 9.7 which only supports class-file version <=67
(Java 23). Server module uses --release 25 (version 69), so server classes
are silently skipped. allowEmptyShould=true prevents the resulting empty
predicate sets from being treated as failures. Shared-module rules still
evaluate correctly from JAR entries. TODO: remove once ArchUnit is upgraded
to a version with Java 25 bytecode support.
ArchUnit 1.3.0 / ASM 9.7 silently skips Java 25 class files (v69 > v67 supported). Server module rules match zero classes and fail by default. Adding .allowEmptyShould(true) per-rule is more reliable than archunit.properties which is not picked up in Gradle test isolation.
