ChatFlex
Overview
This mod introduces a customizable chat system, allowing server owners to create and manage multiple chat channels with specific settings. The mod can operate with or without the LuckPerms mod, providing flexibility in permissions management.
Key Features
Custom Chat Channels: Define multiple chat channels with unique settings, including:
- ID: Unique identifier for each channel.
- Name: Display name of the channel.
- Format: Customizable message format for the channel.
- Prefix: Character(s) used to identify the channel when sending messages.
- Range: The distance (in blocks) that the channel is active. Use
-1for global channels. - Permissions: Control access to channels using LuckPerms or OP-level checks.
- Cooldown: Time in seconds that players must wait before sending another message in the channel.
- Default Channel: Specify a default channel for messages that do not match any prefix.
LuckPerms Integration:
- If LuckPerms is available, the mod will use it to manage permissions for each channel.
- If LuckPerms is not found, the mod defaults to OP-level permission checks.
Configuration
Channels are configured in a JSON file located at config/chatflex/channels.json. The mod will create a default configuration if the file does not exist.

"id": "global",
