ChainTogether Mod (Minecraft Forge) Functional Specification Document

Mod Overview

ChainTogether is a multiplayer interaction enhancement mod tailored for the Minecraft 1.20.1 Forge environment. By introducing a player-to-player leash binding mechanism, it strengthens the team connection experience in collaborative multiplayer scenarios. The core design follows a closed-loop logic of Visualized Binding - Collaborative Status Synchronization.

Core Functional Modules

1. Bidirectional Player Binding Mechanism

   • Supports establishing a binding relationship between two players via item interaction (right-click the target player while holding a leash) or command triggering. In non-Creative Mode, the binding operation consumes 1 leash item.
   • A single player can only maintain a binding relationship with one other player at a time to avoid redundant association logic.

2. Visualized Binding Feedback

   • Upon successful binding, a real-time dynamic chain effect is rendered between the two players. Its visual properties (length, angle) automatically adapt to the relative positions of the bound players. The chain’s length multiplier and transparency parameters can be adjusted via commands.

3. Collaborative Status Synchronization

   • Bound players share their spawn point settings, ensuring collaborative continuity for team members in Survival Mode.

4. Status Management Functionality

   • Supports two unbinding modes: active unbinding (triggered by commands) and passive unbinding (when the distance between players exceeds the threshold). In both scenarios, Chinese prompt messages are pushed to the associated players.

Command System Specification

Command Format	Function Description
/chain bind <player1> <player2>	Establish a binding relationship between two specified players
/chain unbind <player>	Terminate the current binding relationship of the specified player
/chain length <multiplier>	Adjust the multiplier parameter of the chain’s visual length
/chain transparency <10~100>	Set the rendering transparency of the chain (value range: 10-100)
/chain list	View the list of all active binding relationships on the server
/chain reload	Reload the mod’s configuration files

Operation Specifications & Compatibility Notes

1. Operation Workflow

   • Binding: Obtain a leash → Right-click the target player while holding the item → Receive the prompt message "Successfully bound to [Player Name]"
   • Unbinding: Trigger the unbind command / Exceed the maximum distance threshold → Receive the prompt message "Successfully unbound from [Player Name]"

2. Restriction Rules

   • Distance Limit: A maximum distance threshold is set between bound players; the binding will be automatically terminated if the threshold is exceeded.
   • Relationship Limit: A single player can only be part of one binding relationship at a time.

3. Compatibility

   • Only compatible with the Minecraft 1.20.1 Forge server and client environments.
