GregTech Calculator Board

[2.0.0-alpha.9] - 2026-08-26

Added

• Native EMI Recipe Transfer ([+]) Button & Drag-and-Drop Integration (BoardEmiRecipeHandler, BoardEmiDragDropHandler, CalcBoardEmiPlugin):
  • Clicking EMI's native [+] button while viewing recipes with the Calculator Board open now directly instantiates and adds the recipe as an active node onto the canvas.
  • Supports dragging recipes directly from EMI onto the board canvas to place new nodes.
• Multiblock Construction Bill of Materials (BOM) System (RFC-003, MultiblockBOMCalculator, MultiblockStructureCatalog, MultiblockBOMDialog, MultiblockBOMEmiRecipe, MultiblockBOMTest):
  • Added dedicated global/per-page BOM calculation dialog opened via hotkey B or the [📦 BOM] toolbar button.
  • Categorizes structure parts into Casings, Coils, Hatches/Buses, and Controllers with precise stack and remainder formatting (e.g. 3 stacks + 48 (240)).
  • One-click [★ Register in EMI] button to register the aggregated construction parts as a virtual root recipe in EMI's crafting tree for effortless ingredient tracing.
  • Added [📋 Copy List] clipboard text export functionality.
  • Real-time dual lower-tier energy hatch toggle (⚡ 1x Normal Energy Hatch ↔ 2x 1-Tier Lower Energy Hatches).
• Energy Hatch & Dynamic Hybrid Hatch Override System (RFC-004, GTEnergyHatchAddon, GTHatchAddon, EnergyHatchHelper, GTHatchHelper):
  • Determines multiblock voltage tier and amperage (1A, 2A, 4A, 16A, etc.) through equipped energy hatch addons with automatic tier overclock ceiling clamping.
  • Dynamically calculates needed I/O bus and hatch counts based on slot capacities (1x, 4x, 9x, 16x) and enforces Distillation Tower single-fluid hatch constraints.
• Horizontal Node Flip (RecipeNode, NodeCardRenderer, BoardHotkeyHandler, NodeFlipTest):
  • Hotkey Alt + F or card flip button ([⇄]) horizontally mirrors input (left) and output (right) slot layout to minimize wire crossings in dense process layouts.
• Lifecycle Event Bus & Addon Hooks System (RFC-001, RecipeNodeEvent, FlowGraphEvent, MachineCatalogEvent, LifecycleEventBusTest):
  • Standardized Forge event bus hooks notifying external listeners on node lifecycle stages (create, modify, delete, pre/post calculation, and catalog build).
• GregTech Large Multiblock Steam Boilers & Throttle Control (GTBoilerTier, GTCEuRecipeHandler, GTCEuModAdapter, MachineConfigDialog):
  • Accurately parses Large Boiler recipes (gtceu:large_boiler), calculating baseline steam production (\(800\text{ mB/t} = 16,000\text{ mB/s}\)) and water consumption (\(5\text{ mB/t} = 100\text{ mB/s}\), 1:160 ratio) for the Large Bronze Boiler.
  • Multi-tier speed scaling for large boilers: L-Bronze \(1.0\times\) (\(800\text{ mB/t}\)), L-Steel \(2.25\times\) (\(1,800\text{ mB/t}\)), L-Titanium \(4.0\times\) (\(3,200\text{ mB/t}\)), and L-Tungstensteel \(8.0\times\) (\(6,400\text{ mB/t}\)).
  • Integrated 25% ~ 100% Throttle slider and preset buttons in MachineConfigDialog and node cards, dynamically scaling duration, fuel burn rate, and steam output.
• Canvas Group Frame Selection Model, Clipboard & Undo/Redo Integration (BoardSelectionModel, CanvasGroupFrameRenderer, CanvasInteractionHandler, NodeClipboard, BoardCommand, CanvasGroupFrameTest):
  • Full marquee box selection and Shift/Ctrl multi-selection support for group frames.
  • Comprehensive clipboard support (Ctrl + C, Ctrl + V, Ctrl + X, Ctrl + D, Delete) for frames and contained nodes, preserving relative layout coordinates upon paste.
  • Complete history tracking (Undo / Redo) for frame creation, deletion, movement, and resizing.
  • Prevented duplicate delta application (Double-Delta) when dragging multiple selected frames and nodes.
• Create: New Age Carbon Brushes Generator Coil & Magnet BOM Aggregation (MultiblockBOMCalculator, CreateNewAgeModAdapter, IModAdapter, CreateNewAgeTest):
  • Extended IModAdapter.populateExtraBOMParts SPI to automatically include 1x Generator Coil (create_new_age:generator_coil) per Carbon Brushes machine under the COIL category in the BOM.
  • Automatically aggregates all installed singleblock and kinetic addons (up to 12 magnets per generator, thermal augments, threading helixes) into the BOM multiplied by machine count.
  • Classified MAGNET items under the COIL category, properly displaying them in the Coils and All BOM tabs.
• Muffler & Maintenance Hatch Catalog and BOM Support (MultiblockStructureCatalog, MultiblockBOMCalculator, GTCEuModAdapter):
  • Added Muffler Hatches (LV~MAX) and Maintenance / Auto-Maintenance Hatches to the catalog and BOM construction blueprints.
• Star Technology Sterile Cleaning Maintenance Hatch Support (StarTAddonCrawler, StarTModAdapter, MachineAddonTest):
  • Added start_core:sterile_cleaning_maintenance_hatch to the maintenance addons catalog with full localization support.

Changed & Improved

• Background Data Indexing & Memory Footprint Optimization:
  • Optimized recipe search token caching and indexing throughput, eliminating frame drops and reducing memory allocation during startup and recipe search.
• Flow Graph JSON Serialization Payload Optimization (FlowGraphSerializer):
  • Omitted default field values during graph serialization to significantly minimize blueprint and NBT data size.
• UI Layout and Toolbar Margin Polish (BoardScreen, ToolbarWidget):
  • Refined toolbar button boundaries and padding, improving Favorites Dock placement and responsiveness.
• Magnet & Multi-Stackable Addon Click Interaction (MachineConfigDialog, CreateNewAgeModAdapter):
  • Left-clicking catalog cards now stacks addons (+1) up to 12 slots, while Shift + Left-Click fills remaining slots (+12) or batch-replaces them.
  • Right-clicking uninstalls 1 copy (-1), and the top Clear Magnets button resets all installed magnets.
• Deferred Addon Tooltip Rendering (MachineConfigDialog):
  • Resolved UI layering bug where lengthy addon descriptions were clipped by dialog boundaries.

Fixed

• Auto Connect Duplicate Bypass Wire Prevention (ToolbarWidget):
  • Prevented redundant direct bypass wires from being created between producers and consumers that are already routed through a reroute junction hub.
• Large Boiler Recipe Double-Acceleration Duration Bug (GTCEuRecipeHandler, GTCEuModAdapter):
  • Fixed an issue where singleblock boiler speed multipliers were redundantly applied to large boiler recipes, distorting cycle duration down to 0.05s (1 tick) and vastly overconsuming fuel.
• HP Steam to Electric Singleblock Machine Icon Recovery Bug (CategoryCapabilityMatrix, GTCEuModAdapter, GTCEuSteamProcessingTest):
  • Fixed an issue where disabling HP Steam mode unexpectedly promoted singleblock machines to multiblock icons instead of restoring the original tier-specific singleblock workstation.
