ZombieApocalypseSSS

[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.
