中文名：[Fabric]等价交换:重置版
Minecraft 1.21.1 Fabric Edition

Overview

ProjectEF is a modern Fabric port inspired by the classic Equivalent Exchange 2 and ProjectE systems.

The project focuses on bringing the complete EMC-based transmutation experience to Minecraft Fabric, including item value systems, transmutation devices, collectors, condensers, powerful matter tools, and alchemical equipment.

ProjectEF is designed for Minecraft 1.21.1 Fabric while maintaining compatibility with the original ProjectE data structure where possible.

Forge Config API Port and fabric-permissions-api are included inside the ProjectEF JAR.

Building from Source

Clone the repository:

git clone https://github.com/wchiway/ProjectEF.git

cd ProjectEF

Build the project:

./gradlew build

Windows:

gradlew.bat build

Build output:

build/libs/

Run the Fabric development client:

./gradlew runClient

The development recipe viewer defaults to JEI. The recipe_viewer property accepts jei, emi, rei, hybrid, or none.

To use EMI or REI:

./gradlew runClient -Precipe_viewer=emi
./gradlew runClient -Precipe_viewer=rei

Compatibility Notes

ProjectEF keeps the original ProjectE mod identifier:

projecte

This allows compatibility with:

• Existing configuration files
• Existing resource paths
• Existing world data

Accessory slots are provided through Trinkets. Install it to equip rings, amulets, charms, and Klein Stars in the hand/ring and chest/necklace slots. ProjectEF works without it; the accessories simply stay regular inventory items.

The following integrations from the NeoForge version are not included:

• CraftTweaker
• The One Probe
• Curios (replaced by Trinkets on Fabric)

• ProjectEF version
