Cauldron Optimization│煉藥鍋優化
by Special_TT
Cauldron Optimization changes how cauldrons behave: liquid stays in a cauldron after the block is destroyed, and water and powder snow cauldrons stop harming players.
What it does
Normally a cauldron that is broken loses the liquid inside it. With Cauldron Optimization installed, the water, lava or powder snow stays in place after the cauldron is destroyed, so a player can keep a filled cauldron without rebuilding it. Standing in a water cauldron normally causes harm, and a powder snow cauldron normally freezes the player; the mod removes both effects.
The mod is open source under the MIT License and needs TT's Lib│特特的庫 to run. The server must run it, while players may add it but do not have to. Files are published for Fabric, Forge, NeoForge and Quilt, covering 1.21 – 1.21.11 in 12 release versions, and the latest file targets 1.21.11. Snapshot builds are not mentioned.

A powder snow cauldron no longer freezes the player who stands in it.

Use cases
Keeping filled cauldrons
Players who fill a cauldron as a water or lava source can break and move it without losing the liquid.

Who it’s for: Server owners and players on Fabric, Forge, NeoForge or Quilt who want cauldrons to keep their contents and stop harming players.
