PermaEfe Extreme Survival

This update introduces a comprehensive optimization and modernization pass for the PermaEfe datapack to ensure full compatibility with version 1.21 syntax and standards. We successfully integrated and scaled vanilla structures such as Bastions, Ancient Cities, Mineshafts, and Desert Pyramids within the custom dimension while resolving height limit block entity errors by adjusting End Gateway NBT data and implementing a custom placed feature to restrict vertical sculk generation. Server performance was significantly improved by migrating heavy, fast-clock commands into efficient tick-based scoreboard timers and schedule loops, ensuring safe entity clearing that protects minecarts, boats, and utility mobs. The environmental hazard system, featuring toxic rain, deep-layer darkness, Nether heat, and End fatigue, was completely rewritten using staggered timers to apply and clear status effects fluidly without causing server lag spikes. We completely overhauled the Enderman loot table to natively handle custom ender pearl behavior and dimension-specific echo shard drops that now scale accurately with the Looting enchantment. Additionally, an absolute anti-cheat mechanism was implemented to prohibit bucket crafting from day 17 onwards by replacing the recipe with a dummy item that instantly executes lethal magic damage upon the player. Finally, the nightmare teleportation system was thoroughly refactored utilizing chunk force-loading and precise player tagging, guaranteeing flawless transitions to the dark dimension and safe returns to the bed marker without accidentally triggering the generation of standard obsidian escape portals.
