# NeoSync<\/p>\n
> **One mind. Many bodies.**<\/p>\n
NeoSync brings the legendary **Sync** experience to **NeoForge 1.21.1**.<\/p>\n
Grow extra bodies, or *shells*, each with its own inventory, experience level, and gamemode. Swap your consciousness between them at will. Die in a shell? You wake up in another.
\n Leave one parked in the Nether while you mine the Overworld. Keep a spare set of enchanted gear loaded in a shell halfway across the server. The possibilities are yours.<\/p>\n
—<\/p>\n
## How it works<\/p>\n
1. **Craft a Shell Constructor** and place it down.
\n 2. **Provide a genetic sample** \u2014 right-click with an empty hand.
\n > \u26a0\ufe0f With default config this costs **20 HP** (40 in hardcore). Hold a totem, eat a golden apple, or flip `warnPlayerInsteadOfKilling` in the config if you’d rather not die
\n for science.
\n 3. **Power the Constructor.** Place a **Treadmill** next to it, lure a pig or wolf onto the front block, and piggawatts flow. Or hook it up to any Forge Energy source from your
\n favourite tech mod.
\n 4. **Craft a Shell Storage**, place it, and feed it **redstone** or **FE**.
\n 5. Walk into an open Shell Storage and a **radial shell menu** appears \u2014 pick your destination body and **sync**.<\/p>\n

## Features<\/p>\n
– **Cross-dimensional syncing.** Park shells in the Overworld, Nether, End, or any modded dimension and sync between them instantly.
\n – **Per-shell inventory, XP, and gamemode.** Each shell is a fully independent body with its own loadout and progression.
\n – **Death handoff.** If a shell dies, you auto-sync back to your original body or to a random remaining shell if the original is gone. Shell deaths **don’t** count toward your
\n death counter.
\n – **Automation support.** Pipe armor and tools into a Shell Storage to equip the parked shell, or pull gear back out.
\n – **Dye your storages.** Right-click a Shell Storage with dye to color-code it makes spotting “the mining shell” across a dozen containers easier.
\n – **Configurable sync priority.** On death, auto-sync to the `NATURAL`, `NEAREST`, or dye-color-matched shell of your choice.
\n – **Flexible power.** Shell Storages accept raw redstone signal **and\/or** FE. Treadmills output FE to any energy-accepting block.
\n – **Comparator output.** Containers emit signal based on either **build progress** or **inventory fullness** \u2014 right-click with a wrench (stick by default) to toggle.<\/p>\n

## Blocks & Items<\/p>\n
| Block \/ Item | Purpose |
\n | — | — |
\n | **Shell Constructor** | Consumes FE to grow a new shell from your genetic sample. |
\n | **Shell Storage** | Houses a shell; walking in opens the radial selector. Needs power to keep the shell alive. |
\n | **Treadmill** | Two-block structure. Lure an animal on; it walks; FE flows. |
\n | **Sync Core** | Key crafting ingredient \u2014 combine with gray concrete to make either shell container. |<\/p>\n
—<\/p>\n
## Mod Integration<\/p>\n
– **JEI** \u2014 in-depth info panels on every sync block explaining the workflow, plus a *Treadmill Energy Sources* category
\n listing every supported entity and its FE\/tick output.
\n – **Jade** \u2014 crosshair tooltips for Shell Constructors, Storages, and Treadmills showing owner, build progress, color,
\n powered state, and energy.<\/p>\n
Both are optional. NeoSync runs fine without them.<\/p>\n

## Configuration<\/p>\n
Everything is tunable in `config\/neosync-common.toml`. A taste of the knobs:<\/p>\n
| Key | Default | Effect |
\n | — | — | — |
\n | `enableInstantShellConstruction` | `false` | Instant shell builds in creative. |
\n | `warnPlayerInsteadOfKilling` | `false` | Don’t kill low-HP players on fingerstick. |
\n | `fingerstickDamage` \/ `hardcoreFingerstickDamage` | `20` \/ `40` | HP consumed per shell sample. |
\n | `shellConstructorCapacity` | `256000` | FE needed to finish a shell. |
\n | `shellStorageCapacity` \/ `shellStorageConsumption` | `320` \/ `16` | FE buffer + per-tick drain to keep a shell alive. |
\n | `shellStorageAcceptsRedstone` | `true` | Accept raw redstone signal as power. |
\n | `shellStorageMaxUnpoweredLifespan` | `20` | Ticks a storage holds a shell without power. |
\n | `energyMap` | chicken=2, pig=16, player=20, wolf=22, villager=25, creeper=80, enderman=160 | FE\/tick each entity generates on a treadmill. |
\n | `syncPriority` | `NATURAL` | On-death auto-sync target: `NATURAL`, `NEAREST`, or any dye color. |
