CursedAddons

Description

CursedAddons is a Minecraft Fabric mod that enhances chat functionality with keybindings, aliases, chat notifiers, and the ability to view onClick actions for rich messages.

Features

  • Command Keybindings: Define custom hotkeys and key combinations (e.g., Shift+F1) to instantly send predefined chat messages or commands.
  • Command Aliases: Create shortcuts for frequently used commands or messages (e.g., /s → /say or /about → Hello, my name is John Smith).
  • Click Events Preview: When hovering over clickable text in chat, preview what actions will occur (opening URLs, running commands, copying to clipboard, etc.) before clicking.
  • Image Hover Preview: Preview images directly in chat by hovering over image URLs. Supports PNG, JPG, GIF, and WebP with domain whitelisting.
  • Chat Notifications: Set up custom notifications for specific chat messages using string matching or regex patterns. Notifications can play sounds, set window titles, or execute commands when triggered.
  • Fake Chat Messages: Send custom formatted messages to chat using tellraw JSON syntax, including colors, links, and interactive elements.
  • Fixes MC-122477: Fixes a bug on Unix systems where the key to open commands and/or chat can sometimes be doubled when pressed.

Installation

Prerequisites

  • Minecraft Java Edition 1.21.11 (currently supported; future versions may be supported in updates)
  • Fabric Loader 0.18.2 or newer
  • Fabric API 0.141.3+1.21.11 or newer

Steps

  1. Install Fabric Loader: If you haven't already, download and install the Fabric Loader for Minecraft 1.21.11 from the Fabric website.
  2. Download Fabric API: Download the Fabric API for 1.21.11 from its Modrinth page.
  3. Download CursedAddons
  4. Place Mods in mods folder:

    • Locate your Minecraft installation directory.
    • Navigate to the mods folder. If it doesn't exist, create one.
    • Place the downloaded fabric-api-*.jar and cursedaddons-*.jar files into the mods folder.
  5. Launch Minecraft: Start the Minecraft launcher, select the Fabric profile, and launch the game.

Usage

CursedAddons can be configured through its configuration screen, accessible in two ways:

  • Via ModMenu: If you have ModMenu installed, go to Mods → CursedAddons → Config
  • Via Command: Type /cursedaddons in chat to open the configuration screen

For per-feature setup instructions, see the Feature Guide.

Regex Tester

For debugging ChatNotifications regex patterns, use the online regex tester. It allows you to:

  • Test patterns against Minecraft chat messages with § color codes
  • See capture groups in the same format used by the mod ($0, $1, etc.)
  • Preview how color codes will appear visually
  • Convert & color codes to § automatically (like the mod does)
