What's new

Release v1.2.1

This update improves the configuration system and enhances the internal logic for better stability. This version is designed to be a standalone, lightweight alternative for preventing slime spawning in Superflat worlds.

New Features and Improvements

  • Real-time Changes: All configuration categories now support changes during runtime without requiring a game restart.
  • Check Cache: Implemented a 5-second verification cache to reduce unnecessary world-type queries.
  • Thread Safety: Core operations and statistics tracking now use atomic operations for better consistency.
  • Statistics System: Added an in-game command interface to monitor blocked spawns in real-time.
  • Expanded Config: Organized settings into two dedicated categories: General and Performance.

Technical Implementation

  • Memory Management: Optimized to maintain a minimal footprint by using a temporary cache and atomic counters.
  • Processing: Logic is designed to exit as early as possible if conditions aren't met, ensuring minimal impact on game ticks.
  • Thread-Safe Counters: Lock-free statistics tracking for better performance in multi-threaded environments.
  • GC-Friendly: Reduced object creation during spawn events to keep the garbage collector load low.

How to Use

  • For Players: Install the mod and access settings via Mods > No Slime Superflat > Config. You can use the /noslimesuperflat command to verify status.
  • For Debugging: Enable "Debug Logging" in the config to track configuration reloads and blocked spawns in the logs. Use /noslimesuperflat stats for live data.

Compatibility

  • Minecraft: 1.12.2
  • Forge: 14.23.5.2847 or higher
  • Environment: Fully compatible with both Client and Server environments.
