GTToolMapper: GregTech & ProjectE Integration

GTToolMapper is a specialized compatibility addon that bridges the gap between GregTech CEu Modern and ProjectE.

By default, ProjectE cannot "see" recipes inside complex GregTech machines (like the Assembler, Chemical Reactor, or Fluid Extractor). This means complex components like Electric Motors, Circuits, and Cables often have no EMC value, breaking the progression in high-power modpacks like Monifactory.

This mod acts as a custom EMC Mapper, scanning GregTech's internal recipe registries and teaching ProjectE how to calculate costs for machine-only items.

⚠️ Important Note: This is a Mapper Only

This mod is a Recipe Calculator, not a Value List.

• It calculates the EMC of complex items (like Robot Arms) by adding up the cost of their ingredients.
• It does not assign arbitrary EMC values to raw base materials (like Raw Rubber, Chrome, or Naquadah).

For this mod to work, your base materials must already have EMC. If you are playing a custom pack, you may need to add those base values yourself or install a complementary mod like GTmoreEMC to provide the starting values for GregTech materials.

Key Features

• Machine Recipe Scanning: Automatically maps recipes from the Assembler, Chemical Reactor, Fluid Extractor, Wiremill, and more.
• Fluid EMC Support: Successfully calculates EMC for GregTech fluids (e.g., Molten Iron, Rubber, Soldering Alloy) by tracing them back to their solid ingot/dust forms.
• Recursive Calculation: Fixes the "missing link" in recipe chains. If a Cable needs Molten Rubber, and Molten Rubber comes from Sulfur, this mod connects the dots so the Cable gets an EMC value.
• Exploit Prevention: Includes standard checks to prevent infinite EMC loops, compatible with ProjectE's built-in exploit logging.

How It Works

1. Install the Mod: Drop the .jar into your mods folder alongside GregTech CEu Modern and ProjectE.

2. Launch the Game: The mapper runs automatically during the server startup/recipe registration phase.

3. Check Your EMC: Items that were previously un-mappable (like Cables, Rotors, and huge pipes) should now have valid EMC values derived from their raw materials.

Requirements

• Minecraft Version: 1.20.1
• Dependencies:
  • GregTech CEu Modern
  • ProjectE

This mod is designed for the community and is open for inclusion in any modpack.
