📖About Contagious Effects

Contagious Effects

A Minecraft Fabric mod that enables status effects to spread between nearby players.

Overview

Contagious Effects adds a new layer of interaction to multiplayer Minecraft by allowing potion effects to propagate between players within a configurable range. When a player carries a status effect, nearby players have a chance to contract the same effect, simulating a form of proximity-based transmission.

Features

Configurable Range: Set the distance over which effects can spread (default: 2 blocks)
Spread Intervals: Control how frequently the mod checks for effect transmission (default: every 10 ticks)
Cooldown System: Prevent constant re-application with a configurable cooldown period
Smart Overwriting: Option to only replace existing effects if the incoming effect is stronger or longer-lasting
Player State Filtering: Automatically exclude spectators and creative mode players from both spreading and receiving effects
In-game Configuration: Full integration with ModMenu and Cloth Config for easy adjustment of all settings
