Three Players One Body

3-in-1 Player Plugin - Feature Overview

What This Plugin Does

This plugin allows 3 players to control 1 character simultaneously. All three control players are conjoined inside the movement player - they occupy the same body and see what the main player sees!

The Three Roles

ATTACK Role (Player 1)

- Controls: Combat and attacking - Can Do: - Punch/attack mobs and other players (if PvP enabled) - Use swords and weapons - Swing animations - Visibility: INVISIBLE (hidden inside the main player) - Collisions: Non-collidable; avoids pushing and prevents aim jitter - Perspective: Sees what the movement player sees (camera follows main player)

BREAK_PLACE Role (Player 2)

- Controls: Block interaction - Can Do: - Break/mine blocks - Place blocks - Use tools - Visibility: INVISIBLE (hidden inside the main player) - Collisions: Non-collidable; avoids pushing and prevents aim jitter - Perspective: Sees what the movement player sees (camera follows main player)

MOVE Role (Player 3 - Main Player)

- Controls: Movement and position - Can Do: - Walk around and move the character - Sprint and jump - Use elytra (if creative) - Interact with the world physically - Visibility: VISIBLE (the only visible character) - Perspective: The main character everyone perceives

Shared Resources

All three players share: - Health: If one takes damage, all see the damage - Hunger: All three players have the same hunger level - Saturation: Eating food affects all three - Inventory: Items are synchronized - if one player adds an item, all see it - Body Position: All three occupy the exact same location (inside the main player) - Camera/Crosshair: All three see the same view as the movement player

How It Works in Practice

Example Scenario: Fighting a Mob

1. Player 3 (MOVE) walks up to a Creeper using their movement 2. Player 1 (ATTACK) punches the Creeper repeatedly 3. Player 2 (BREAK_PLACE) is doing something else (breaking a nearby tree) 4. The Creeper takes damage from Player 1's attacks 5. If the Creeper explodes, all three players take damage equally 6. If any player needs to heal, all three eat from the shared inventory

Example Scenario: Mining

1. Player 3 (MOVE) walks to a mine 2. Player 2 (BREAK_PLACE) breaks blocks and collects ore 3. Player 1 (ATTACK) fights off any mobs that appear while mining 4. The ore goes into the shared inventory that all three can see
