AutoEMC
Managing a massive "kitchen-sink" modpack in Minecraft often leads to a broken economy within ProjectE. Manually assigning Energy-Matter Covalence (EMC) values to thousands of items from dozens of mods is an impossible task for most server administrators. This is where AutoEMC steps in as a vital Forge mod designed to bridge the gap between complex recipe trees and a functional transmutation system. By automatically scanning your loaded mods and deriving logical values, it ensures every item has a price without requiring hours of manual configuration.
How AutoEMC Solves the Pricing Puzzle
The core philosophy of this tool is simple: never replace existing values, only fill the voids. When your server or single-player world starts, the mod analyzes every registered recipe. If an item lacks an EMC value but its ingredients are priced, AutoEMC calculates the output cost based on the total input divided by the yield. This recipe-solving method is the preferred approach because it grounds the economy in actual gameplay mechanics rather than arbitrary numbers.
In newer iterations supporting Minecraft 1.20.1, the system runs multiple solving passes. This allows chains of dependencies to resolve in stages; for instance, it can price an ingot, then use that value to price a block, and finally a machine component. For older versions like 1.16.5, it utilizes bundled mapping data from ProjectE Integration to treat non-standard conversion mechanics as valid recipes, ensuring even obscure industrial items get accurate valuations.
Intelligent Fallback Systems
Not every item in a modpack has a crafting recipe. Some are generated via world generation, boss drops, or complex machine processes that the mod cannot trace. In these scenarios, the mod switches to a sophisticated fallback hierarchy. It first checks bundled baseline values for popular mods like Botania, Mekanism, and Create. If no specific baseline exists, it analyzes material tags.
For example, if the system encounters an unknown copper variant, it identifies the forge:ingots/copper tag and assigns a value relative to standard copper ingots. It understands that a storage block should be worth roughly nine ingots, while a nugget is one-ninth. As a last resort, it employs a rarity and tier-based system. This prevents powerful late-game items like Draconic or Allthemodium gear from being undervalued as common junk, assigning them "Very Strong" or "OP" tiers to maintain economic balance.
If you are looking to streamline this entire process, the foxygame.net launcher offers a unique advantage by featuring a curated add-on catalog where you can find AutoEMC with one-click installation and automatic version compatibility checks. This eliminates the hassle of manually matching mod loaders and ensures your pack launches with the correct dependencies immediately.
Safety Features and Economy Protection
Automated systems carry risks, but AutoEMC is built with strict safety rails to prevent economic collapse. A fundamental rule is that it will never intentionally lower a value set by ProjectE or a pack author. It only fills gaps or raises its own previous estimates if new recipe evidence justifies a higher cost. To prevent creative-only technical items from becoming infinite money glitches, any item with no recipe and flagged as creative-only is locked to a single EMC point by default.
Furthermore, the mod includes large-drop protection. If a scan suggests a drastic price change that exceeds a configurable ratio, the change is blocked and logged to a quarantine report instead of being applied silently. This ensures that a weird recipe interaction doesn't suddenly make diamonds worthless or iron infinitely expensive. The system also tracks ownership, distinguishing between values it generated and those manually defined, allowing it to update its own guesses in future scans without overwriting human intent.
Handling NBT Data and Variants
Modern modpacks frequently use NBT data to differentiate items, such as enchanted books, potions, or materials with specific attributes. AutoEMC includes a pluggable NBT material resolver framework that prices these variants based on their embedded content rather than treating them as generic items. This is crucial for mods like Avaritia, where singularities must be priced based on their constituent materials plus a multiplier. To prevent performance issues, users can cap the number of variants generated per item ID, ensuring the scan remains efficient even in huge packs.
Installation and Configuration
To get started, you need to download AutoEMC and place it in your mods folder alongside ProjectE and ProjectE Integration. The mod supports Minecraft 1.16.5 and 1.20.1 on the Forge loader. Once installed, the first startup may take several minutes as the mod scans thousands of items and recipes. Patience is key here; the console logs will show progress, and a completion message will appear when the custom_emc.json file has been successfully written.
Configuration is handled via the autoemc-common.toml file. Users can toggle features like solveRecipes, adjust the maxRecipePasses, or disable fallback pricing entirely for stricter control. For server admins running version 1.20.1, there is even a /autoemc rescan command to force a fresh calculation without restarting the server. Detailed logs are generated in the config folder, allowing you to audit exactly why specific values were assigned, tracing sources from baseline data to rarity fallbacks.
By automating the tedious math of modded economies, this tool allows players to focus on exploration and engineering rather than spreadsheet management. Whether you are running a lightweight tech pack or a behemoth collection of hundreds of mods, integrating this solution ensures a balanced and enjoyable transmutation experience for everyone.
