[0.2.40] - 2026-04-18

Added — Full i18n / Localization overhaul

The mod now fully integrates with Minecraft's translation system. Players with any interface language see all text in their own language — no hardcoded strings remain in player-facing output.

• ~53 Java files fixed — replaced Component.literal("text") with Component.translatable("key") and I18n.get() throughout all GUI screens, game logic, network packets, and event handlers
• 224 translation keys per language file, covering all UI screens, HUD strings, chat messages, tooltips, and admin menus
• Added ~80 new translation keys to en_us.json and uk_ua.json: PvP HUD strings, lobby/portal/boundary messages, PlayerSettings, HudEdit, HudLayout presets, AdminMenu, server-side game messages, wave/round/match events, completion rewards
• 6 new language files (complete translation of all 224 keys):
  • 🇩🇪 de_de.json — Deutsch
  • 🇫🇷 fr_fr.json — Français
  • 🇪🇸 es_es.json — Español
  • 🇵🇱 pl_pl.json — Polski
  • 🇧🇷 pt_br.json — Português (Brasil)
  • 🇨🇳 zh_cn.json — 简体中文
• WaveManager.java — added broadcastToLocation(String, Component) overload; changed endSessionForLocation to accept a Component directly; all 30+ broadcast calls converted to Component.translatable()
• HudLayout.Preset — enum now stores a translation key instead of a raw display string; preset buttons rendered via Component.translatable()
• WaveActionsScreen — tooltip system refactored from text-matching to Map<Button, String> (works correctly regardless of active language)
• HudOverlay — PvP HUD status lines (pvp.buy_phase, pvp.round_active, pvp.waiting) converted from hardcoded Ukrainian to i18n keys
• PlayerSettingsScreen, HudEditScreen, AdminMenuScreen, CompletionRewardScreen — all labels, buttons, hints, and error messages converted to translatable keys
• KeyBindings.java — "leaving location" and "shop unavailable in spectator" messages converted
• All network packets (PurchaseItemPacket, TeleportPacket, ImportLocationPacket, ExportLocationPacket, AdminTeleportPacket) — server responses now use Component.translatable(), resolving client-side in the player's language

Fixed — Scroll buttons in 8 admin screens (critical UI bug)

Scroll buttons (▲/▼) in 8 admin screens were registered via addRenderableWidget() and fell under the scissor clip — they became invisible and unclickable when a list appeared.

Fixed (addRenderableWidget → addStatic):

• AdminMenuScreen — location list
• CompletionRewardScreen — reward list
• WaveConfigScreen — wave list
• PlayerMenuScreen — location list for player
• PlayerShopScreen — item list
• MobSelectionScreen — mob list
• WaveMobsEditorScreen — wave mob list
• LocationEditorScreen — mob spawn point list

Fixed — Memory leak on player disconnect

When a player disconnected while inside a location, playerData, playerBackups, and reEntryCooldowns were not cleaned up. Added a PlayerLoggedOutEvent handler in EventHandler: on logout, surrenderPlayer() is called, properly restoring inventory and clearing all internal maps.

Fixed — reEntryCooldowns memory leak

Entries in reEntryCooldowns (UUID → timestamp) accumulated indefinitely. Added automatic removal of expired entries once per minute (every 1 200 ticks).

Fixed — PurchaseItemPacket (TOCTOU + NPE)

• References to ShopPoint, sourceList, and ShopItem are now captured atomically
• Added null checks at every step (guards against NPE when an admin edits the shop concurrently)

Fixed — ImportExportScreen rebuild race

rebuildWidgets() could run after the screen was already closed (packet arrives while the player has opened a different screen). Added a minecraft.screen == this guard before rebuild.

Optimization — getPlayersInLocation() per-tick cache

The method was called 40+ times per tick, each time iterating over all playerData (O(n) per call). It now builds a shared Map<String, List<ServerPlayer>> once per tick; all subsequent calls are O(1) lookups. The cache is invalidated on player join/leave.

Optimization — HudOverlay rendering

• Eliminated duplicate mc.font.width() calls (previously computed separately for each line)
• Block width is now calculated in a single pass
