Astatine 1.12.2
A lightweight Minecraft mod offering performance tweaks, visual enhancements, and gameplay adjustments.

Features

Performance Tweaks

Fast Random (Experimental)
Optimizes random number generation for smoother gameplay. May improve performance but use with caution—untested edge cases could cause instability.
This is a backport of Francium mod.
FastLang
Accelerates language switching by reloading only language files (no full resource reload like F3+T) and using a faster parser.
FastLang mod implemented the first featrue,only load neccessary resources.
Chunk Caching
Reduces lag by intelligently caching frequently loaded chunks. Customize retention time, cleanup intervals, and cache size, see the configure file for details.

Visual Improvements

Starfield Overhaul
Redesigns the night sky! Adjust star count, size, randomness algorithms, and set a custom RNG seed.
Star Twinkling
Adds dynamic twinkling stars using a sine-based brightness curve. Tweak frequency, amplitude, and base brightness for your ideal sky.
Force ASCII Font
Fixes font rendering issues that game always render text as Unicode-style if their language has non-ASCII characters.
ForseASCIIFont mod did the same thing.Thanks!

Gameplay Adjustments

Eating Anytime
Bypass hunger checks to eat food anytime you want. Configurable for creative mode or just remove the checks completely.
World Time Scaling
Slow down the day-night cycle by updating world time every N ticks.
Item Stack Merging
Merge stacks beyond stack limits (e.g., 1024 cobblestones) to reduce ground item lag.This would not affect the actual stack limit!
Rendering Skip
Boost FPS by ignoring distant entities/tile entities beyond a set render distance.
A backport of Out Of Sight mod.
Projectile Hiding
Reduce visual clutter by hiding newly thrown projectiles (arrows, eggs, etc.) until they’ve existed for a configurable time.

Configuration

File: config/astatine.properties (generated automatically with comments).
Warning: Configs load once at startup—no in-game reloading. A planned migration to a dynamic system (ConfigAnyTime) will add real-time editing.

Planned Features

To be actual implemented would be a far time.

Rework rain/snow effects for better performance or aesthetics.
Migrate current configuration system to the ConfigAnyTime Mod which support runtime configuration modifying and visual config screen.Incompatible with current configuration file syntax.

These features are in development/under consideration.

Stats System Removal
Completely remove player statistics tracking.Potentially breaks advancements!
Smart Chunk Saving
Save only chunks with high inhabitTime (player activity). Villages will be generated in new structures every times(even on same seed).Regenerating a chunk within the scope of a village will reveal this issue, causing structural chaos (conflicts between saved chunks and unsaved structures).

Misc Optimizations
Replace other unimportant things (e.g., HashSet<Long> → LongOpenHashSet,a faster data collection) for memory/performance gains. Toggle via miscOptimization options.
