UI-Utils CevAPI 2.4.0 - Minecraft 1.21.11

This repository is a fork of UI-Utils updated specifically to support Minecraft 1.21.11.

This fork was created and shared with the blessings of MrBreakNFix.

What it is

UI-Utils adds extra in-GUI utilities for debugging and testing inventory/container interactions, including tools for controlling packet sending behavior and fabricating GUI-related packets.

Key features

• In-GUI buttons + a text field when you open inventories/containers
• Close GUI without sending a close packet
• Client/server GUI de-sync tools
• Toggle sending GUI click packets on/off
• Delay packets and flush them later
• Save the current GUI for later access via keybind
• Packet fabrication tools:
  • ClickSlotC2SPacket
  • ButtonClickC2SPacket
• Copy GUI title JSON
• Chat/command box usable while inside a GUI
• Optional resource pack bypass/deny tools (server-dependent)

Note: Some features may be unreliable on macOS (especially packet fabrication UI).

Compatibility

• Minecraft: 1.21.11
• Loader: Fabric
• Requires: Fabric API

Usage

Open any inventory/container in-game and you should see UI-Utils controls on the screen.
(See the upstream documentation/screenshots for full feature explanations.)
