This is a updated version of the original Sync mod by iChun. We have permissions to port and update the mod as we want.

Sync provides clones, or as we like to call it, "shells". These shells are basically a new individual, with their own inventory, experience level, and even gamemode.

However, what they lack, is a mind to control them. That’s where the player comes in. Each shell is biometrically tied to the player who’s sample is used to create it, and will allow the player to “sync” their mind to the other shell, essentially creating multiple player instances.

Place a shell constructor down and right click it to provide a sample (warning, this hurts!). The shell constructor cannot work without power, so put a treadmill down next to it and lure a Pig or a Wolf to the center of the treadmill to generate Piggawatts. A lead will help out out with this (you will get it back). The shell constructor will begin building a shell.

Once the shell is constructed, you need to place down a shell storage unit and supply redstone power to it. The indicator will switch to green and you can walk into the storage unit to activate it. You will see a radial menu pop up with the list of available shells and their positions. Select the shell in the constructor (labelled with the “Done” indicator) and watch as you are synced into the new shell.

Shell syncing works cross dimensional too! Get to the nether and back through a shell! However, you cannot enter or leave shells in The End due to…. technical difficulties.

By default, shells provide an “extra life” to the player. When the shell you are using dies, you will immediately resync to the nearest shell available. You can mark a preference shell by right clicking a storage unit with a bed, labelling it as a home storage unit. You can also name storage units with a name tag. This “extra life” feature works in Hardcore mode, so if you have an active backup shell you will not be forced to abandon a hardcore world, but instead resync to another shell.

Sync - Create Multiple Bodies, One Mind

Ever wanted to be in two places at once? Now you can.

What is Sync?

Sync enables you to create shells - physical clones of yourself with independent inventories, experience levels, and gamemodes. Transfer your consciousness between shells instantly across any dimension.

Originally created by iChun, this NeoForge port brings the beloved mod to modern Minecraft while preserving all its unique features.

✨ Features

• Multiple Bodies - Create and maintain several shells across your world
• Cross-Dimensional Travel - Instantly transfer between shells in different dimensions
• Death Insurance - When a shell dies, return to another shell instead of respawning
• Individual Stats - Each shell has its own inventory, XP, and gamemode
• Biometric Lock - Shells are tied to their creator
• Automation Support - Use hoppers for automatic shell equipment management
• Color Coding - Organize shells with dyes
• Energy System - Powered by adorable animals on treadmills (piggawatts!)
• Highly Configurable - Customize every aspect via config

🎮 Quick Start

1. Create a Shell Constructor

Craft a Shell Constructor and right-click it to provide a genetic sample.

⚠️ Warning: Default config costs 20 HP (40 HP in Hardcore). Use golden apples or totems!

2. Generate Energy

Place a Treadmill adjacent to the Shell Constructor and lure a pig or wolf onto it.

3. Build Shell Storage

Craft a Shell Storage, power it (redstone or energy), and walk inside when doors open.

4. Transfer Minds

Use the radial menu to select and transfer into your desired shell!

💡 Pro Tips

• Organization: Color-code Shell Storages with dye
• Monitoring: Use comparators to track construction progress
• Safety: Mine Shell blocks with Silk Touch only
• Automation: Connect hoppers to shells for inventory management
• Power: Shell Storages need constant power (configurable)
• Dimensions: Works with custom dimensions!
