Vanish++

Added

• can_throw VRule: New personal rule controlling whether vanished players can throw items (eggs, snowballs, ender pearls, potions, bows, crossbows). Default: false. Fully integrated with interactive chat buttons ([Allow 1m], [Allow permanently], [Hide notifications]).
• Staff Glow Indicator: Vanished players now render with a glowing outline for staff with vanishpp.see. Uses packet-level metadata injection — non-staff never see it. Enabled by default (vanish-appearance.staff-glow: true).
• Vanish State Resync Engine: New resyncVanishEffects() system that reapplies all vanish state (team, prefix, metadata, fly, night vision, collision, mob targeting, visibility, glow) without touching storage. Triggered automatically on respawn, world change, and gamemode change.
• Respawn Handler: Vanish state (fly, invisibility, glow, collision) is now fully restored after death and respawn.
• World Change Handler: Nether/End portal transitions no longer break vanish state.
• Gamemode Change Handler: Changing gamemode (e.g., /gamemode survival) while vanished no longer disables flight.
• [Unvanish] Button: All blocked-action messages now include a convenient [Unvanish] button alongside [Allow 1m], [Allow permanently], and [Hide notifications].
• Fast Sync Loop: Heartbeat task now runs every 10 ticks with visibility fix, team/prefix reapply, glow metadata resend, and mob targeting — ensuring all vanish features stay in sync continuously.
• Explicit Glow Metadata Packets: Staff glow is now sent via direct ProtocolLib ENTITY_METADATA packets rather than relying on entity respawn metadata, ensuring the glow appears instantly.
• Multi-Stage Join Prefix: Tab prefix is now reapplied at 2, 20, and 60 ticks after join — catches TAB plugin async overrides at different pipeline stages.
• Snapshot Silent Chests: Barrels and containers are now opened as inventory snapshots (copy of the real inventory). Changes sync back on close. This eliminates Container.startOpen() entirely, preventing animation and sound at the source.
• Reload Resync: /vreload now refreshes team prefix and resyncs all online vanished players' effects.
• Setup Advisor (Config Sanity Checker): On startup, Vanish++ now scans the active configuration and warns if:
  • hooks.simple-voice-chat.enabled is true but SimpleVoiceChat is not installed.
  • hooks.essentials.simulate-join-leave is true but EssentialsX is not installed.
  • Any message string contains a PlaceholderAPI placeholder (%token%) but PlaceholderAPI is not installed.
  • Warnings are printed to the console and shown in-chat to all players with vanishpp.see on their next login, making it easy to spot setup issues without reading logs.
• Comprehensive Automated Test Suite: 143 unit tests across 6 test classes covering every feature — commands, event listeners, storage, permissions, rules, and integration scenarios. All tests pass on clean build.
• Full Localization (i18n): Complete multi-language support.
  • All messages and system reports moved to lang/en.yml.
  • Automatic fallback system for missing keys.
  • Simplified config.yml with a new language toggle.
• Rich Text Support: Integrated MiniMessage for modern, easy-to-read chat formatting using tags (e.g., <red>, <bold>, <click>).
• PlaceholderAPI Integration: Full support for dynamic placeholders in all plugin messages and the Action Bar.
• Folia Support: Rewritten scheduler and event handling to support Folia's multi-threaded region architecture.
• Config Reload: Added /vreload command to apply configuration and language changes instantly without server restarts.
• Interactive Reports: Professional clickable components in all command outputs.
• Titan Stealth Engine: Absolute packet-level invisibility for vanished administrators. The server now acts as if the vanished player does not exist in the network data.
  • Tab List & Info Filtering: Blocked PLAYER_INFO and PLAYER_INFO_UPDATE packets to prevent any tab list flicker or presence detection.
  • Ghost-Proof Spawning: Intercepted SPAWN_ENTITY and NAMED_ENTITY_SPAWN to ensure vanished players are never spawned on unauthorized clients.
  • Absolute Metadata & Update Blocking: High-priority interceptors for ENTITY_METADATA, ENTITY_EQUIPMENT, ANIMATION, ENTITY_EFFECT, ENTITY_STATUS, and ENTITY_SOUND_EFFECT to ensure zero data leakage.
  • Movement & Velocity Filtering: Blocked ENTITY_VELOCITY, REL_ENTITY_MOVE, ENTITY_LOOK, ENTITY_TELEPORT, and ENTITY_HEAD_ROTATION to eliminate coordinate-level leaks.
  • Action Scrubber: Intercepted COLLECT (item pickups) and SET_PASSENGERS (mounting) to scrub vanished names even when they are not the primary entity.
  • Team Scrubbing: Intercepted SCOREBOARD_TEAM to remove vanished names from any raw team packets sent to non-staff.
• Plugin Hiding: "Vanishpp" is now hidden from /plugins (or /pl) for non-OPs. Administrators see a filtered list with a delayed interactive notification to temporarily unhide or acknowledge the feature.
• Strict Command Permissions: All commands now enforce strict permissions in plugin.yml. Unauthorized players cannot see commands in Tab-Complete.
• Config Logic: vanishMessage, unvanishMessage, fakeJoinMessage, and fakeQuitMessage logic updated. Setting these to "false", "none", or leaving them empty in config.yml now properly disables the message.
• Persistence: Acknowledging the plugin hiding warning now saves the preference to data.yml specifically for the current version.

Changed

• Silent Chest Architecture: Replaced the spectator-mode workaround with a snapshot inventory system. Vanished players now open a copy of the container, and edits sync back on close — no animation, no sound, full item interaction.
• Throwable Blocking: Throwables (eggs, bows, ender pearls, etc.) are now governed by the can_throw VRule instead of being unconditionally blocked. Players can toggle this rule like any other.
• Spawn Egg Messages: Spawn eggs now use the standard sendRuleDeny system with can_throw, providing interactive buttons instead of a static message.
• Sound Suppression: Silent chest sound listener now covers both NAMED_SOUND_EFFECT and CUSTOM_SOUND_EFFECT packets with robust multi-offset coordinate detection.
• Config Structure: Significant cleanup of config.yml. Legacy message blocks removed in favor of lang/*.yml.
• Performance: Optimized visibility checks and metadata handling for better server performance.

Fixed

• DiscordSRV Join/Quit Suppression: DiscordSRV now fully suppresses join and quit announcements on Discord for players who rejoin with persisted vanish state. Previously, only chat suppression worked — Discord join messages leaked through.
• Barrel/Shulker Silent Opening: Opening barrels and shulker boxes while vanished no longer leaks the open/close animation or sound to nearby players. Previously, the Container.startOpen() call triggered both.
• Join Prefix Delay: The vanish tab prefix ([V]) now appears within ~100ms of joining instead of taking 3+ seconds. Multi-stage reapplication handles TAB plugin async overrides.
• Throwable Items Leaked Position: Throwing eggs, snowballs, ender pearls, and shooting bows while vanished created visible projectile entities that revealed the player's position. Now blocked by default via the can_throw rule.
• Spawn Egg Rule Bypass: The CAN_INTERACT rule had no effect on spawn eggs due to incorrect check ordering. Spawn eggs are now properly governed by can_throw.
• Vanish State Lost on Respawn: Dying and respawning while vanished caused loss of fly, invisibility, glow, collision settings, and night vision.
• Vanish State Lost on World Change: Entering nether/end portals broke vanish state (visibility, fly, glow, prefix).
• Flight Lost on Gamemode Change: Running /gamemode survival while vanished disabled fly mode permanently until re-vanishing.
• Reload Didn't Resync: /vreload previously only reloaded config files without resyncing active vanish effects for online players.
• Mob Targeting on Vanish: Mobs that had already acquired a player as their target before /vanish was used would continue attacking. Fixed by explicitly clearing all matching mob targets within 64 blocks the moment a player vanishes.
• Console Staff Notification: Console was silently excluded from vanish/unvanish staff notifications. It now receives the same message as staff players with vanishpp.see.
• Fly Mode Logic: Improved flight persistence on unvanish when configured.
• Dependency Resolution: Fixed an issue where the ProtocolLib dependency was not correctly detected on first install.
