Season System

Season System 1.1.1 - Fabric 26.2

Version 1.1.1 focuses heavily on multiplayer performance, improved winter behavior, better cave handling and several fixes for snow and ice placement.

Performance Improvements

• Significantly optimized seasonal environment calculations.
• Reduced expensive block and height scans around players.
• Replaced several vertical block scans with Minecraft heightmap checks.
• Heavy seasonal calculations are now distributed across players instead of running for every player at the same time.
• Optimized snow and ice protection checks.
• Removed unnecessary registry, string and reflection checks from frequently executed block update paths.
• Optimized crop and terrain checks.
• Reduced unnecessary season synchronization traffic.
• Regular season synchronization interval increased from 1 second to 5 seconds.
• Season changes and player joins are still synchronized immediately.

Summer Changes

• Players inside proper underground caves will no longer receive summer heat debuffs.
• Being underneath a tree, roof or small structure does not count as being inside a cave.
• The system now checks whether the player is sufficiently below the terrain surface.

Winter Changes

• Holding a torch in the main hand or off-hand now provides warmth.
• Players holding a torch receive a small movement speed bonus during winter.
• Held torches prevent the normal cold movement penalties.
• Regular Torches, Soul Torches and supported Copper Torch variants are recognized.

Snow Placement Fixes

• Snow will no longer be placed on Carpets.
• Snow will no longer be placed on Chests.
• Snow will no longer be placed on Ender Chests.
• Snow will no longer be placed on Trapped Chests.
• Snow will no longer be placed on Anvils.
• Snow will no longer be placed on Enchanting Tables.
• Snow will no longer be placed on Brewing Stands.
• Snow will no longer be placed on Fences.
• Existing protection for unsuitable blocks such as slabs, stairs, trapdoors, walls and similar blocks remains active.
• Invalid seasonal snow placement can now be cleaned up more reliably.

Water Freezing Improvements

• Only full source water blocks can now freeze into ice.
• Flowing water will no longer freeze.
• Partial flowing water levels will no longer incorrectly turn into full ice blocks.
• Water near torches will no longer freeze.
• Torch heat checks use a limited nearby radius to avoid introducing new performance issues.
• Regular Torches, Wall Torches, Soul Torches, Soul Wall Torches and supported Copper Torch variants can protect nearby water.

Bug Fixes

• Fixed several cases where seasonal calculations could cause unnecessary server tick load with multiple players.
• Fixed snow being generated on unsuitable functional and decorative blocks.
• Fixed flowing water incorrectly being converted into ice.
• Fixed water freezing directly next to heat-providing torches.
• Improved seasonal environment handling for multiplayer servers.

Recommended update:
This version is especially recommended for multiplayer servers, particularly servers with several players online at the same time.
