Random Optimization

Description

This mod implements the following features to significantly optimize game performance and fix existing bugs. All features can be toggled via the configuration file.

• Fixes MC-249136: This bug causes severe server lag (hangs) when players attempt to locate Buried Treasure (most notably), or when opening/breaking chests containing maps, or using the /locate command. This mod employs simple checks to drastically reduce the enumeration required during structure searching, thereby optimizing speed.
• Deterministic Item Drops: The mod de-randomizes the spawn position of dropped items. This makes designing Redstone contraptions much simpler and easier. Additionally, by reducing the usage of RNG (Random Number Generation), it improves game performance.
• Optimized Resource/Data Pack Loading: Improves the loading speed of Resource Packs and Data Packs.
• Boat Fall Damage Fix: Fixes an issue where boats take fall damage when falling from specific heights. This aligns behavior with the MC-Wiki description and newer Minecraft versions, while also improving performance.
• DFU Optimization: Defers (lazy loads) the DataFixerUpper (DFU) to improve game startup speed.

Compatibility & Replacements

This mod completely or partially replaces the functionality of the following mods:

• MC-249136 Fix: This mod fundamentally optimizes the structure search algorithm. In contrast, other mods often move the task to a separate thread to mask the lag. While technically not conflicting, using this mod usually provides sufficient optimization, making the other mod unnecessary. If you strictly require asynchronous loading, Async Locator is recommended instead, as it supports more structures and has a better implementation.
• Shipwreck/Buried Treasure Fixes: This mod shares the same essential optimization logic for MC-249136. There is no need to use those mods if this one is installed.
• Vertical Fall: This mod completely replaces all functionality of this mod.
• Drizzleproof: Partially replaced. If you only need deterministic item drops, you do not need Drizzleproof. However, if you require granular configuration for entity mechanics, please continue using Drizzleproof.
• Quick Pack: Both mods cache resource pack reading. This mod's optimization is less aggressive than Quick Pack but is more memory-efficient. If Quick Pack is detected, this mod's corresponding feature will be automatically disabled.
• Boat Break Fix: This mod completely replaces the functionality of this mod.
• DFU Loading Optimizations (e.g., LazyDFU): This mod completely replaces the functionality of these mods.
