MtnEnderFix v1.1.2 — Performance Overhaul & Critical Bug Fixes

A major update focusing on zero-lag performance, resolving false positives on wall decorations, preventing pearl loss, and introducing full dual-language support (English & Spanish).

Bug Fixes & False Positive Corrections

• Wall Decoration False Positives Fixed: Fixed an issue where wall torches, redstone torches, wall signs, wall banners, player heads/skulls, and coral wall fans were falsely identified as solid walls due to a broad name check. Wall glitch detection now strictly targets actual wall blocks (*_WALL).
• Point-Blank Pearl Refund: Fixed an issue where cancelled point-blank throws permanently consumed the player's Ender Pearl even when refund-pearl: true was enabled. Cancelled throws now properly refund the item to the player's inventory (or drop it at their feet if full).
• Head-Level Suffocation & Clipping Prevention: hasAdjacentWallOverlap previously only checked feet-level blocks. It now validates both feet (Y) and head (Y+1) heights across all 8 cardinal and diagonal directions, completely preventing head-suffocation in stairs, overhangs, and diagonal corners.
• Long-Distance / TP Desync Protection (>120 blocks): If a player throws a pearl and is teleported far away before it lands (e.g., via /rtp, /tpa, /home), the plugin now verifies whether the pearl landing spot is safe. If unsafe or inside a wall, the teleport is safely cancelled with a refund, preventing players from suffocating or glitching into claims.

Performance & Server TPS Optimizations

• Zero Synchronous Chunk Loading: All block lookups and path raytraces now perform bitwise chunk loaded checks (isChunkLoaded) before querying blocks, ensuring the main thread never stalls waiting for chunk generation or loading.
• Massive Garbage Collector (Heap) Reduction:
  • Replaced repeated .clone().subtract(...) and .clone().multiply(...) chains inside backtracking loops with primitive double coordinate calculations.
  • Replaced to.clone().add(0, 1, 0).getBlock() with direct relative block fetching (feetBlock.getRelative(BlockFace.UP)).
  • Converted adjacent face arrays into a cached static final BlockFace[] constant, eliminating array re-allocation on every collision.
• Faster Math: Replaced Math.pow(dx, 2) + Math.pow(dz, 2) with direct primitive multiplication dx * dx + dz * dz.
• Raytrace Distance Capping: Capped isPathClear checks to a maximum of 6 blocks, discarding unnecessary world raytracing calculations.

Dual-Language & Clean-up

• English & Spanish Localization: Full native language files (en.yml and es.yml).
• Empty Prefix Bug Fixed: Resolved an issue where disabled or empty messages still displayed the plugin prefix in chat.
• Command Help Localization: Added {label} placeholder support and localized help strings for /mtnenderfix.
• Memory Leak Clean-up: Properly invalidated static instance references in onDisable().
