GregTech Calculator Board
by Amvermain
GregTech Calculator Board is a Forge and NeoForge tool for drawing recipe flowcharts in-game, so a production line can be planned without leaving Minecraft.
What it does
Players build flowcharts as a visual node graph where each machine's inputs and outputs link to the next step. The chart can be balanced and simulated across an entire production line, using recipes from GregTech CEu Modern. Required machines and multiblock parts are totaled automatically, and the resulting bill of materials can be exported to EMI Recipe, or copied to the clipboard with Tree JEI++.
Teams can work on the same chart together. Shared workspaces update in real time, and collaboration relies on FTB Teams, Phoenix Guilds or Vanilla Scoreboards for membership. The mod is client-side only, so only the player's client needs it and a server can run without it. It is released under the MIT License, and its source code and issue tracker are public. Required dependencies are Applied Energistics 2, Create, Create: New Age, Greate, GregTech CEu Modern, Thermal Expansion and Thermal Foundation. Recipe viewing works with EMI, which is recommended, or Just Enough Items (JEI).
Key features
Visual flowcharts
Machine inputs and outputs are placed as nodes and linked together, then the whole chart can be balanced and simulated.
Bill of materials export
Required machines and multiblock parts are aggregated into a list that can be exported directly to EMI or copied to the clipboard.
Shared workspaces
Several players can edit one chart at the same time, with changes shown live.
Recipe viewer support
Recipes pull from EMI or JEI, so the chart is built from the same recipe data the player already browses.
