### ✨ Natural spawning — all 7 structures Added `StructureHelper.levelFoundation()`: before any other building happens, it now levels the footprint to a flat pad at the resolved ground Y — filling gaps below (so floors don't float over a dip) and clearing bumps above (so a mound or tree stump can't poke through a wall), capped at 6 blocks either way so a badly out-of-range forced spawn can't dig an enormous hole. Wired into all 7 structures' `spawn()`. #

## [4.6.0] — Full Bug Sweep + New Structures 10 bugs found and fixed via full manual code review of every source file (not a targeted diff — every `.java` file was read end-to-end), plus 2 new structures. ---

## [4.5.2] — Bug-Fix Release ### 🔴 Critical Fixes #### BUG-1 · Boss Zombie drops Diamond Armour on death - **File:** `ZombieSpawnService.java` — `spawnBossZombie()` - **Root cause:** `setArmorContents()` was called without setting drop chances to 0. Bukkit's default drop chance is ~8.5%, so players could farm Diamond Helmet / Chestplate by killing the Boss. - **Fix:** Added explicit `setHelmetDropChance(0f)`, `setChestplateDropChance(0f)`, `setLeggingsDropChance(0f)`, and `setBootsDropChance(0f)` after every armour assignment, including the custom-model-data head path. #### BUG-2 · Boss HP inconsistent — `evolveZombie()` multiplier overridden - **File:** `ZombieSpawnService.java` — `spawnBossZombie()` - **Root cause:** `spawnCustomZombie()` internally called `evolveZombie()` which applied a tier health multiplier (up to ×2.5 for ABERRANT), but `spawnBossZombie()` then hard-reset the attribute to `boss.health` config value, discarding the tier scaling entirely. - **Fix:** `spawnBossZombie()` now sets `bossHealth` first, *then* calls `evolveZombie()` so the tier multiplier compounds on top of the intended base. Boss HP in late-game now scales correctly with the threat level. --- ### 🟡 Medium Fixes #### BUG-3 · ABERRANT zombies appear ~35 days too early - **File:** `ZombieEvolutionService.java` — `determineTier()` - **Root cause:** The `else` branch covered `threat >= 30`, but the class-level comment stated *"Threat > 50: Aberrant possible"*. Players hit ABERRANT-tier enemies during Phase 3 (Day ~15) instead of Phase 5 (Day ~25+). - **Fix:** Inserted an explicit `threat < 50` bracket (no ABERRANT, Mutated max) and moved ABERRANT to `threat >= 50` only, matching the original design intent. #### BUG-4 · `/zapoc infect` shows hardcoded `"10m"` regardless of config - **File:** `ZombieApoc.java` — `onCommand()` case `"infect"` - **Root cause:** `incubationTicks` was read from config but immediately discarded; the player message used the literal string `"10m"`. - **Fix:** `timeDisplay` is now derived from `incubationTicks / 20` seconds so the displayed time always reflects the actual configured value. #### BUG-5 · ZombieBehaviorTask batch-skipping uses `hashCode() % 2` (uneven distribution) - **File:** `ZombieBehaviorTask.java` — `run()` - **Root cause:** `UUID.hashCode()` is a 32-bit hash with no uniformity guarantee. In practice this can result in 70 % of zombies processed on one tick and 30 % on the other, defeating the purpose of two-bucket batching. - **Fix:** Changed the modulus operand to `UUID.getLeastSignificantBits()` which is a raw 64-bit random value from the UUID v4 spec, giving near-perfect 50/50 split. #### BUG-6 · `HallucinationListener` double-registration on `/zapoc reload` - **File:** `ZombieApoc.java` — `startTasks()` - **Root cause:** `startTasks()` checked `if (hallucinationListener == null)` before creating a new instance, but `cancelAllTasks()` already set it to `null`. In specific edge cases (e.g. `psychological-horror.enabled` toggled via config between reloads) the old instance could survive unregistered yet the new instance would be registered on top. - **Fix:** `startTasks()` now unconditionally calls `HandlerList.unregisterAll()` and nulls the field before constructing a fresh `HallucinationListener`, making the lifecycle explicit and immune to ordering issues. #### BUG-7 · `WorldEventTask` blood-moon maps leak UUID entries for unloaded worlds - **File:** `WorldEventTask.java` - **Root cause:** `bloodMoonStates` and `bloodMoonRolledDay` used world UUIDs as keys but never removed entries when a world was unloaded (e.g. on map rotation or `/mv unload`). Over time this created an unbounded set of stale entries. - **Fix:** `WorldEventTask` now implements `Listener` and handles `WorldUnloadEvent` to remove both maps' entries for the unloaded world. The task is registered and unregistered as a listener in `startTasks()` / `cancelAllTasks()`. --- ### 🟢 Minor Improvements #### PERF-1 · ZombieBehaviorTask reads 7 YAML values every 10-tick cycle - **File:** `ZombieBehaviorTask.java` - **Root cause:** `moanEnabled`, `moanChance`, `moanVol`, `moanPitch`, `mutationEnabled`, `mutationInterval`, and `breakingEnabled` were fetched from `FileConfiguration` on *every* call to `run()`. - **Fix:** All seven values are now cached as class-level fields alongside the existing sun / screamer caches and refreshed once every 100 ticks inside `reloadSunConfigCache()`. #### PERF-2 · `handleExplosive()` reads `explosive.power` from YAML at explosion time - **File:** `ZombieBehaviorTask.java` - **Fix:** Added `cachedExplosivePower` field, populated in `reloadSunConfigCache()`. #### PERF-3 · `CampfireManager.isInsideSafeZone()` reads `check-radius` from YAML per call - **File:** `CampfireManager.java` - **Root cause:** `plugin.getMechanicsConfig().getInt("campfires.check-radius", 100)` was called on every invocation. `isInsideSafeZone()` is called once per second per online player from `PlayerStatusTask`, making this a hot path. - **Fix:** Added `cachedCheckRadius` field, initialised in the constructor and refreshed in `reload()`. #### DEPRECATION-1 · `TurretListener` used legacy `ChatColor` string API - **File:** `TurretListener.java` - **Fix:** All player messages converted to `net.kyori.adventure.text.Component` using `NamedTextColor` and `TextDecoration`, the standard approach on Paper 1.16+. #### DEPRECATION-2 · `ZombieApoc.sendActionBar()` used BungeeCord spigot bridge - **File:** `ZombieApoc.java` - **Fix:** Replaced `player.spigot().sendMessage(ChatMessageType.ACTION_BAR, ...)` with the Paper-native `player.sendActionBar(Component)` call. Removed unused `net.md_5.bungee.api.*` imports. ---

## [4.5.1] - 2026-05-20 - Critical Bug Purge III ### Fixed - **Turret system completely non-functional — Adventure vs. Legacy API mismatch (BF-16)** — The crafting recipe assigned the "Sentry Turret" display name via the Adventure API (`meta.displayName(Component.text(...))`). `TurretListener.isTurretItem()` read the name with the deprecated Legacy API (`meta.getDisplayName()`), which always returns an empty string when the name was set via Adventure — so the check never matched and `TurretManager.createTurret()` was never called. Placing a crafted turret had no effect. `isTurretItem()` now reads the Adventure `displayName()` component first, serialises it to plain text, and falls back to the legacy accessor for pre-migration items. - **`onDisable()` never called `turretManager.cleanup()` — turret data loss on restart (BF-17)** — `CampfireManager.shutdown()` was called in `onDisable()` but the analogous `TurretManager.cleanup()` call was absent. `cleanup()` is responsible for cancelling the internal firing task and flushing `turrets_data.yml`. Turrets placed during a session without a prior auto-save were silently lost on server restart. `turretManager.cleanup()` is now called from `onDisable()`. - **`/zapoc reload` wiped all zombie custom AI — missing `scanExistingZombies()` call (BF-19)** — `loadConfig()` (called by `loadAllConfigs()` at the start of every reload) called `trackedZombies.clear()`. `ZombieBehaviorTask` iterates that collection each tick; after a reload it was empty, so every living custom zombie lost its AI (no moans, no screaming, no sun effect, no mutation) until the zombie died or new ones spawned. `scanExistingZombies()` is now called at the end of the reload handler to repopulate the map immediately. - **`/zapoc reload` did not rebuild `TurretManager` — config changes had no effect (BF-18)** — `TurretManager` reads `range`, `damage`, and `fire-rate-ticks` only in its constructor. After a reload the old instance kept running with stale values. The reload handler now calls `turretManager.cleanup()` and recreates a fresh `TurretManager`, matching the pattern already applied to `StructureManager`. - **Feign-Death zombie permanently invulnerable and AI-less after server restart (BF-20)** — When a Feign-Death zombie "died", the code set `invulnerable=true` and `AI=false`, then scheduled a `BukkitRunnable` to revive it after 3–5 s. If the server restarted during that window, the task was discarded but the entity flags persisted in NBT — leaving an immortal, motionless zombie that could never be killed. A new PDC key `feign_active` is set at the start of feign-death and cleared on revive. `ZombieCleanupListener.onChunkLoad` now detects this key and immediately invokes the shared `SpecialZombieListener.reviveZombie()` method, which also handles the scheduled revive path. - **`CampfireManager.damageCampfire()` triggered a full YAML write on every zombie hit (BF-21)** — `saveCampfires()` (atomic file I/O on the main thread) was called each time a zombie attacked a campfire. With multiple zombies attacking multiple campfires simultaneously during a Blood Moon, this caused significant main-thread stalls. Replaced with a dirty flag: damage marks the campfire data as dirty, and the periodic task flushes to disk at most once every ~5 seconds. Immediate saves are still performed when a campfire is destroyed. - **`ZombieBehaviorTask.handleScreamer()` read 6 YAML values per zombie per 0.5 s (BF-23)** — Every invocation of `handleScreamer()` called `getZombiesConfig().getDouble/getString/getInt()` six times. With 20 Screamer zombies that is 120 YAML map lookups per 500 ms. All six values (`scream-chance`, `particle`, `particle-count`, `scream-range`, `darkness-duration`, `message`) are now cached in the same 5-second refresh cycle used by sun-effect config. - **`ZombieBehaviorTask.handleBreaker()` read `success-chance` from YAML per zombie per 2 s (BF-24)** — `zombie-breaking.success-chance` was fetched from `FileConfiguration` inside the per-zombie loop every 40 ticks. Now cached alongside the other task-level values. - **`PsychologicalHorrorTask.activeHallucinations` used entity ID (`int`) as map key (BF-25)** — Entity IDs are 32-bit integers reused by the server after an entity despawns. Using `entity.getEntityId()` as the map key could cause stale `HallucinationData` entries to collide with or shadow new entries sharing the same recycled ID. The key type is now `UUID` (`entity.getUniqueId()`), which is guaranteed unique per entity. - **Campfire heal task used 3×3 chunk scan instead of 5×5 (BF-22)** — `isInsideSafeZone()` and `onSpawn()` were already corrected to 5×5 in a prior release, but the heal loop inside `startTask()` still searched only 3×3 chunks (~32 block reach). Tier-3 campfires have a 40-block radius, so players near the edge of the safe zone were not receiving the Regeneration effect. The heal loop now uses 5×5, consistent with all other campfire range checks. ### Notes - No config file changes are required. All existing `data.yml`, `campfires.yml`, and `turrets_data.yml` files are fully compatible with 4.5.1. - Any turrets placed **before this update** that were saved in `turrets_data.yml` will load and function normally. Turrets placed during a session that ended with a 4.5.0 server stop without an intermediate save may have been lost — this is the bug being fixed. ---

## [4.4.0] - 2026-04-17 - Bug Purge & Correctness Update ### Fixed - **`SurvivalGuideListener.PAGE_KEY` NPE on startup** — `static final NamespacedKey PAGE_KEY` was initialised at class-load time before the plugin instance existed, causing a `NullPointerException` on every server start. `PAGE_KEY` is now an instance field initialised in the constructor. *(BF-01)* - **`InfectionListener` ignored `infection.enabled` config** — infection spread on every zombie hit regardless of `infection.enabled: false` in `config.yml`. `ZombieBehaviorService` already checked the flag but `InfectionListener` did not, making the config option partially ineffective. *(BF-02a)* - **`InfectionListener` ignored `zapoc.immune` permission** — players with `zapoc.immune` could still receive infection points. The permission is now checked in both `InfectionListener` and `ZombieBehaviorService`. *(BF-02b)* - **Day-based spawn-rate (`shouldSpawn()`) was completely bypassed** — `ZombieBehaviorService` runs at `EventPriority.HIGH` and cancelled natural spawns before `SpawnListener` ran, so the phase-based rates (40% / 70% / 90% / 100%) never took effect — zombies always spawned at 100% regardless of server age. `shouldSpawn()` is now called directly inside `ZombieBehaviorService.onCreatureSpawn`. *(BF-03)* - **`TurretManager` could permanently delete `turrets_data.yml`** — the save code called `dataFile.delete()` before `renameTo()`. If the rename failed the data file was gone permanently. Replaced with `Files.move(ATOMIC_MOVE)` and a non-atomic fallback. *(BF-04)* - **Sanity config multipliers loaded but never applied** — `sanityDrainBase`, `nightMultiplier`, `infectedMultiplier`, `lowHealthMultiplier`, and `nearbyZombiesMultiplier` were read from `mechanics.yml` but `updateSanity()` used hardcoded constants. Editing these values in config had no visible effect. All five multipliers are now applied correctly. *(BF-05)* - **`whisperPhrases` config key loaded but never used** — `handleWhispers()` used an internal hardcoded array instead of the phrases from `mechanics.yml`. Player-configured phrases including `phrases-vi` / `phrases-en` are now displayed correctly. *(BF-06)* - **`hg.no-netherite-drop` bypass via corpse zombie** — the death handler stripped netherite from `event.getDrops()` but then re-equipped the corpse zombie with raw armour including netherite. A player could kill the corpse to recover the items. Netherite is now stripped from the corpse's equipment when the option is enabled. *(BF-07)* - **Tank zombie `ENTITY_RAVAGER_STEP` sound spam** — `handleTank()` fired a full-volume step sound every 0.5 s with no throttle, flooding clients when multiple Tank zombies were active. A 10% per-call chance now limits the frequency. *(BF-08)* - **`panicCooldowns` HashMap memory leak** — UUID entries were added on `/zapoc panic` but never removed on disconnect. Entries are now removed in `onPlayerQuit`. *(BF-09)* - **Stalker spawn used zombie's world for player's Y lookup** — `getHighestBlockYAt()` was called on the zombie's world; if the target player had recently changed worlds the Y could be wrong. Player's own world is now used for the lookup. *(BF-10)* ### Performance - **`handleSunEffect()` YAML reads inside per-zombie loop eliminated** — seven `FileConfiguration.get*()` calls per zombie per tick removed. All sun-effect config values are now cached at task level and refreshed every 5 s. Eliminates ~1,400 redundant map lookups per second at 200 tracked zombies. *(BF-11)* - **`Math.random()` replaced with `ThreadLocalRandom` throughout** — 20+ usages replaced across `CampfireManager`, `ZombieApoc`, `ZombieBehaviorService`, `ZombieBehaviorTask`, `PlayerStatusTask`, `WorldEventTask`, `ZombieEvolutionService`, and `SpecialZombieListener`. *(BF-12)* ### Notes - No config changes required. All existing `data.yml`, `campfires.yml`, and `turrets_data.yml` are fully compatible. ---

# ZombieApocalypseSSS – Bug Fix Report (v4.3.2 → v4.3.3) ## Custom Items Retained - **Bandage** – stops bleeding - **Antivirus** – cures infection - **Adrenaline** – speed/strength boost (60s cooldown, crash effect after) - **ZombieCamo** – zombies ignore you for 60s - **Radio** – detect next supply drop location (5min cooldown) --- ## Bug Fixes | # | Severity | File | Description | |---|----------|------|-------------| | 33 | 🔴 | ZombieSpawnService | Zombie names encoded as `§c§lSCREAMER` → fixed to `§c§lSCREAMER`. Affected: SCREAMER, Stalker, Crawler, Feign Death, Boss. Names were rendering as garbage text on all servers. | | 34 | 🔴 | ZombieApoc (onEnable) | `registerRecipes()` was never called — comment `RECIPES REMOVED` was accidentally left after feature re-enable. All 6 vanilla crafting recipes (bandage, antivirus, adrenaline, zombie camo, radio, turret) were silently unavailable. | | 35 | 🔴 | BandageItem | `create()` read `custom-model-data` from `getPluginConfig()` (config.yml) instead of `getItemsConfig()` (items.yml). Bandages would always spawn without CustomModelData, breaking resource packs. | | 36 | 🔴 | SurvivalGuideListener | `SurvivalGuideHolder.getInventory()` returned `null` — violates `InventoryHolder` contract. Fixed: holder stores and returns its own `Inventory` reference. | | 37 | 🔴 | MilitaryCheckpoint | `spawnTowerSniper()` re-rolled random offset/height instead of using the cached `towerBase`/`towerHeight` computed in `cacheTowerPosition()`. Tower snipers could spawn anywhere except the actual tower. | | 38 | 🟠 | AdrenalineItem | `onInteract()` lacked `RIGHT_CLICK_AIR / RIGHT_CLICK_BLOCK` guard. Item could trigger on `LEFT_CLICK_BLOCK` in edge cases. | | 39 | 🟠 | ZombieApoc (TabComplete) | `/zapoc give camo` was listed in tab-complete but the switch-case expected `"zombie-camo"`. Fixed to `"zombie-camo"` in both places. | | 40 | 🟠 | CrashedSupplyPlane | `setMaxHealth()` deprecated since Bukkit 1.16. All mob health now uses `Attribute.GENERIC_MAX_HEALTH.setBaseValue()`. Affected: pilot, supply guard, medic, soldier zombies. | | 41 | 🟠 | MilitaryCheckpoint | Same `setMaxHealth()` deprecation fix for heavy soldiers, commanders, and tower snipers. | | 42 | 🟠 | AbandonedHospital | `WHITE_BED` placement ignored required `BlockData` facing direction — bed failed silently. Replaced with `WHITE_WOOL` as visual equivalent. | | 43 | 🟠 | RadioItem | Lore cooldown update only scanned main hand + off hand. If player moved radio to any other slot the cooldown label stayed stale forever. Fixed to scan full inventory. | | 44 | 🟡 | Structure types (×5) | `isReplaceable()` and `isValidMobSpawn()` copy-pasted in 5 classes. Extracted to new `StructureHelper` utility class. | | 45 | 🟡 | AbandonedHospital, AbandonedOutpostPro, SurvivorCamp | Structure zombies used vanilla `world.spawnEntity()` — bypassing custom AI, tier evolution, sun effects, and tracking. Now use `ZombieSpawnService.spawnCustomZombie()`. | --- ## New Utility Class **`StructureHelper`** (`structure/StructureHelper.java`) - `isReplaceable(Material)` — shared replaceable-block check - `isValidMobSpawn(World, Location)` — 3-block column spawn validation - `setBlockSafe(World/Location, Material)` — convenience block-place wrapper ## [4.3.3] - 2026-04-13 - Bug Purge & Structure Overhaul ### Fixed - **Zombie name encoding** — SCREAMER, Stalker, Crawler, Feign Death, and Boss zombies displayed garbage text (`§c§lSCREAMER`) on all servers due to source-file encoding corruption. All names now render correctly. - **Recipes never registered** — all 6 crafting recipes (Bandage, Antivirus, Adrenaline, Zombie Camo, Radio, Sentry Turret) were silently missing. `registerRecipes()` is now correctly called in `onEnable`. - **Bandage CustomModelData** — `BandageItem.create()` read CMD from the wrong config file (`config.yml` instead of `items.yml`). Bandages now respect resource-pack model overrides. - **SurvivalGuide GUI crash** — `SurvivalGuideHolder.getInventory()` returned `null`, violating the `InventoryHolder` contract. The holder now stores and returns a proper `Inventory` reference. - **Tower sniper spawn position** — `MilitaryCheckpoint` snipers re-randomised their spawn offset on every call instead of using the cached tower position from `cacheTowerPosition()`. Snipers now always spawn on the tower platform they are supposed to guard. - **AdrenalineItem left-click trigger** — added missing `RIGHT_CLICK_AIR / RIGHT_CLICK_BLOCK` guard; item could fire on left-click in edge cases. - **`/zapoc give zombie-camo`** — tab-completion listed `"camo"` but execution expected `"zombie-camo"`. Both are now consistent. - **`setMaxHealth()` deprecation** — replaced all deprecated `LivingEntity.setMaxHealth()` calls in `CrashedSupplyPlane` and `MilitaryCheckpoint` with `Attribute.GENERIC_MAX_HEALTH.setBaseValue()`. - **AbandonedHospital beds** — `WHITE_BED` placement requires directional `BlockData` not set during procedural generation, causing silent failures. Replaced with `WHITE_WOOL` as a visual equivalent. - **RadioItem stale cooldown lore** — cooldown label in item lore only updated when the radio was in the main hand or off hand. Now scans the full inventory so the label always reflects the real cooldown. ### Changed - **Structure zombies now use plugin AI** — `AbandonedHospital`, `AbandonedOutpostPro`, and `SurvivorCamp` spawned plain vanilla zombies that bypassed custom AI, tier evolution, sun effects, and the tracking map. They now call `ZombieSpawnService.spawnCustomZombie()`, so all structure zombies scale with server difficulty like any other custom zombie. Thematic equipment (hospital gown, outpost guard gear, survivor leather) is applied on top of the custom zombie. ### Added - **`StructureHelper` utility class** — `isReplaceable(Material)`, `isValidMobSpawn(World, Location)`, and `setBlockSafe()` were copy-pasted identically across 5 structure classes. This shared utility eliminates the duplication. All structure implementations now delegate to `StructureHelper`. ### Notes - No config file changes required for this update. Existing `data.yml`, `campfires.yml`, and `turrets_data.yml` are fully compatible. - This release is recommended for all servers running 4.3.x. ---

## [4.1] — 2026-03-14 🔧 *The Bug Purge Update* > 23 bugs fixed across all severity levels. This release focuses entirely on > correctness, stability, and developer experience — no new gameplay features, > just a rock-solid foundation. --- ### 🔴 Critical Fixes #### 🏰 Turrets lost on every server restart *(BUG-02)* `loadTurrets()` and `saveTurrets()` were both empty `// TODO` stubs. Every turret placed by players vanished after a restart. **Fix:** Full persistence implemented via `turrets_data.yml` using atomic write (`.tmp` → rename) to prevent data corruption on crashes. --- #### 📦 Supply Drop loot table was never loaded *(BUG-03)* `spawnSupplyDrop()` read `supply-drop.loot` from `config.yml`, but this section is defined in `events.yml`. The config section was always `null`, so every Supply Drop fell back to a hardcoded 5-item list, ignoring all admin configuration. **Fix:** `spawnSupplyDrop()` and all related methods now read exclusively from `eventsConfig` (events.yml). Admin-configured loot tables are now respected. --- #### 🌕 `blood-moon.chance` config had no effect *(BUG-04)* The `bloodMoonChance` field was loaded from config (default 5%) but never referenced in `checkBloodMoon()`. Blood Moon triggered at 100% probability every N days instead of the configured 5% chance. **Fix:** `Math.random() < bloodMoonChance` check added in `checkBloodMoon()`. Blood Moon now correctly triggers by chance each eligible night. --- #### 💥 `NullPointerException` when Molotov reached max range *(BUG-05)* `ProjectileHitEvent` fires when a projectile expires at max range, at which point both `getHitBlock()` and `getHitEntity()` return `null`. The handler assumed at least one was non-null, causing a server-crashing NPE. **Fix:** Three-way null check: hit block → hit entity → projectile location (fallback). --- ### 🟠 High Severity Fixes #### 🩸 Bleeding damage triggered every 40 seconds instead of 2 *(BUG-06)* `PlayerStatusTask` runs every 20 ticks (1 second). The bleeding check used `tickCount % 40 == 0`, which fires every 40 *runs* = every **40 seconds**. Players with bleeding could regenerate faster than they took damage. **Fix:** Changed to `tickCount % 2 == 0` → bleeds every 2 seconds as intended. --- #### ⚠️ No combined cap on zombie difficulty multipliers *(BUG-07)* Three independent scaling systems stacked without a total ceiling: - Global difficulty multiplier (capped at ×3.0 ✓) - Evolution tier multiplier (Aberrant ×2.5 ✓) - Per-player `daysSurvived` scaling (**no cap** ✗) On a 100-day server, the combined multiplier could reach ×26×, making zombies practically unkillable. **Fix:** `daysSurvived` scaling is now capped — health ≤ ×3.0, speed ≤ ×2.0, spawn count ≤ 5 per spawn event. --- #### 🔫 Gun reload lock persisted through player relog *(BUG-08)* `RELOAD_COOLDOWN_KEY` and `FIRE_COOLDOWN_KEY` were stored in `player.getPersistentDataContainer()` as Unix timestamps. If a player disconnected mid-reload and reconnected, the stale future timestamp would lock them out of firing/reloading until the original timer expired. **Fix:** Both cooldowns moved to `ConcurrentHashMap<UUID, Long>` in-memory maps. Cleared automatically when the player disconnects. --- #### 👻 Hallucination Villager stood completely still *(BUG-09)* `updateHallucinations()` called `mob.setTarget(player)` to make hallucinations chase their target. While `Zombie` entities respond to `setTarget()` by pathfinding toward the player, `Villager` ignores it (Villagers don't attack). **Fix:** Villager hallucinations now use `getPathfinder().moveTo(player, 1.15)` with periodic re-pathfind if the current path becomes null. --- #### 👁️ Players who joined late could see hallucination entities *(BUG-10)* `spawnHallucination()` called `hideEntity()` only for players online *at spawn time*. Any player joining after a hallucination spawned would see a phantom zombie/villager wandering around with no explanation. **Fix:** The existing `onPlayerJoin()` handler correctly hides all active hallucinations for new joiners. Spawn-time hiding loop now also reliably covers all current online players. --- ### 🟡 Medium Severity Fixes #### 🪓 Weapon upgrade chain used hardcoded CustomModelData values *(BUG-11)* `FeaturesListener` hardcoded CMDs like `3004`, `3011`, `3005` directly in Java. Changing any `custom-model-data` in `items.yml` would silently break upgrade chains with no error or warning. **Fix:** CMDs are now read from `items.yml` and `mechanics.yml` at runtime. Upgrade chains survive config customization. --- #### 🔥 Campfire data corrupted if world name contained `_` *(BUG-12)* Save keys used `worldName_x_y_z` format. Loading split on `_` and took `parts[0]` as the world name. A world named `my_world` would produce 5 parts instead of 4, causing `parts[0] = "my"` → `Bukkit.getWorld("my") = null` → all campfires lost. **Fix:** Keys now use `worldUUID_x_y_z` (UUID with hyphens stripped = always 32 hex chars, no ambiguous underscores). Legacy world-name keys are still parsed as a migration fallback. #### 🌙 `blood-moon.enabled` / `supply-drop.enabled` read from wrong config *(BUG-14)* Both keys are defined in `events.yml`, but `WorldEventTask.run()` read them from `config.yml`. Since `config.yml` doesn't contain these keys, the fallback `true` was always used — neither event could be disabled. **Fix:** All `WorldEventTask` config reads now use `eventsConfig` consistently. --- #### ☠️ Corpse reanimation could not be disabled *(BUG-15)* When a player died, items were cleared and a zombie "corpse" was spawned wearing their gear. There was no config toggle — servers running minigames or PvP arenas had no way to opt out of this mechanic. **Fix:** Gated behind `corpse-reanimation.enabled` in `mechanics.yml` (default: `true`). --- #### 💬 Misleading comment in `ZombieBehaviorTask` *(BUG-16)* Comment said `// Every 20 ticks = 1s` next to `tickCounter % 2 == 0`. The actual math (task runs every 10 ticks; `%2` = every 2 runs = every 20 ticks = 1s) was correct but the comment was confusing enough to invite accidental breakage. **Fix:** Comment updated to explain the full calculation chain. --- #### 🎆 Default Screamer particle `"PORTAL"` is invalid in Paper 1.21 *(BUG-17)* `Particle.valueOf("PORTAL")` throws `IllegalArgumentException` in Paper 1.21+. The exception was caught and logged, but the screamer ability silently failed every time on unmodified configs. **Fix:** Default changed to `"ENTITY_EFFECT"` in both code and `zombies.yml`. --- ### 🟢 Code Quality | # | Change | |---|---| | 🗑️ BUG-18 | Deleted `manager/ZombieManager.java` — 532 lines of dead code never instantiated. Contained a severe anti-pattern (one `BukkitTask` per zombie). | | 🗑️ BUG-19 | Deleted `manager/EventManager.java` — 739 lines of boilerplate never registered as a Listener in `onEnable()`. | | 📐 BUG-20 | Added missing constants to `ZombieConstants`: AI ranges, noise radii, bleed values, day-scaling caps. Magic numbers reduced across codebase. | | 🏷️ BUG-21 | Renamed `trapKey` / `is_trap` PDC key to `engineeringItemKey` / `is_engineering_item` in `EngineeringTableManager`. Ammo is not a trap. | | 🏷️ BUG-22 | Renamed `ZombieUtils.applyAI()` → `applyFollowRange()`. The method only sets follow range to 40 blocks — the old name implied far more than it did. | | 🧹 BUG-23 | `ZombieCleanupListener` now removes zombies from the tracking map on chunk unload, freeing strong references to de-activated entities and reducing memory pressure on long-running servers. | --- ### ⚙️ Config Changes **`mechanics.yml`** — new keys: ```yaml corpse-reanimation: enabled: true # Set false to disable zombie corpse on player death infection: natural-decay: enabled: true chance-per-second: 0.033 # ~1 point per 30s; 3× faster in Campfire safe zones ``` **`events.yml`** — new key: ```yaml blood-moon: cycle-days: 7 # (moved from config.yml) eligible cycle in days ``` **`zombies.yml`** — changed default: ```yaml screamer: particle: ENTITY_EFFECT # was: PORTAL (invalid in Paper 1.21) ``` --- ### 🧩 API Changes ```java // ✅ Fixed api.isInfected(player) // now correctly returns true when infected // ✅ New api.getInfectionLevel(player) // int 0–5 api.getInfectionPoints(player) // int 0–100 api.setInfectionPoints(player, n) api.getThreatLevel() // double api.getZombieTier(zombie) // ZombieTier enum api.isInSafeZone(location) // boolean api.spawnZombie(world, loc, type) // ⚠️ Deprecated api.infectPlayer(player, ticks) // use setInfectionPoints() instead ``` ---

## [4.0] - 2026-03-12 - Update Checker + Version Bump ### ✨ New Features - **Modrinth Update Checker** — The plugin now checks for new versions on Modrinth during server startup. - Runs fully **async**; won't lag the main thread even if the network is slow. - If an update is available: Prints a clear console notification showing current vs. latest version. - Admins with the `zapoc.admin` permission receive a chat notification upon joining (delayed by 2 seconds to avoid being buried by other login messages). - Can be completely disabled via `update-checker: false` in `config.yml`. - Class: `UpdateChecker.java` — implements `Listener` to hook into `PlayerJoinEvent`. ### 🐛 Bug Fixes - **Messages never loaded (Critical)** — `loadConfig()` called `saveResource("messages_vi.yml")`, but the file is located at `language/messages_vi.yml` inside the JAR. `saveResource` threw a startup exception, leaving `messagesConfig` empty—resulting in every `getMessage()` call returning `§cMissing key: ...`. Fixed by using the correct sub-path and ensuring parent directories are created if missing. - **`/zapoc panic` spawned vanilla zombies** — The command called `ZombieSpawnService.transformZombie(z, "random")`, but `"random"` is not a valid key in the `zombieTypes` map. This caused `data == null`, making the method return immediately without applying stats, AI, or types. All 15 panic zombies were plain vanilla. Fixed by calling `ZombieSpawnService.randomizeZombie(z)`. - **Supply drop interval ignored config** — `WorldEventTask.calculateNextDrop()` attempted to read `plugin.getPluginConfig().getLong("supply-drop.interval")` from `config.yml`, but the key is actually defined in `events.yml`. The interval always defaulted to the hardcoded 18,000 ticks. Fixed by reading from `plugin.getEventsConfig()`. - **Sun effect settings ignored config** — `ZombieBehaviorTask.handleSunEffect()` attempted to read `sun-effect.mode`, `sun-effect.light-threshold`, and related keys from `plugin.getPluginConfig()` (`config.yml`), but those keys reside in `sun-effect.yml`. Sun slow/burn modes always used hardcoded defaults. Fixed by reading from `plugin.getSunEffectConfig()`. ### ⚠️ Minor Fixes - **Bleeding tick check unreliable** — `PlayerStatusTask` used `Bukkit.getCurrentTick() % 40 == 0` to throttle bleeding damage to every 2 seconds. Because the server tick counter and task invocation aren't perfectly aligned, the check fired inconsistently. Replaced with a local `tickCount` field incremented on each run. - **`canSpawnMutated()` allowed 2 Mutated per chunk** — The method returned `count < 2` despite a comment explicitly stating the design cap is 1 per chunk. Adjusted to `count < 1`. - **`ZombieApocRefactored.java` removed** — Cleaned up a dead-code class from a previous refactor attempt. It was never used as the main class and contained inverted command logic. Deleted entirely.
