Just Calculator UI
by lixiao_li
Just Calculator UI adds a calculator page to the in-game interface that works out the materials a recipe needs, so players can plan bulk crafting.
What it does
Players open the calculator page and enter a recipe to see the total of each input it requires, which helps when a large batch of items has to be gathered first. The page works from recipe data already in the game, and the mod is published for Forge only, with files for 1.20.1 – 1.20.6 and 1.1.0 for 1.20.6 as the latest release. It runs on the client alone, so a server does not need to install it.
Key features
Recipe material calculation
The calculator page totals the materials a chosen recipe needs, including the quantities for bulk crafting.
Calculator page in the interface
The calculator is a screen opened from the game interface rather than a chat command, keeping the calculation in view.
Recipe-based input totals
Each ingredient is counted from the recipe, so the list reflects what a craft consumes, not what the player happens to hold.
