Create Toolbox Input Fix

A tiny client-side fix mod for Create on Fabric 1.20.1.

This mod fixes the annoying Toolbox bug where the Toolbox GUI opens twice during a single key press:

• once when pressing the key
• again when releasing it

The issue happens because Create receives both press and release input events and incorrectly opens the Toolbox menu twice.

What this mod does

This mod patches Create's Toolbox input handler and allows the Toolbox GUI to open only once per key press.

Fixed behavior

• Toolbox opens normally on key press
• Releasing the key no longer reopens the GUI
• No more stuck Toolbox menu
• No need to press ESC to close it

Features

• Client-side only
• Lightweight
• No config required
• No gameplay changes
• Safe for existing worlds
• Compatible with Create 6.0.8.1 on Fabric 1.20.1

Compatibility

• Minecraft 1.20.1
• Fabric Loader
• Create Fabric 6.0.8.1
• Fabric API

Technical details

The mod injects into:
ToolboxHandlerClient.onKeyInput

It filters duplicate release-triggered open events while preserving normal key behavior.

Notes

This mod only affects Toolbox input handling.
It does NOT modify:

• inventory behavior
• chat
• other GUI screens
• gameplay mechanics

Funny backstory

I am not a mod developer at all.
I actually made this fix with the help of ChatGPT and Cursor because my perfectionism absolutely could NOT tolerate the Toolbox opening twice every single time.

After spending way too many hours testing configs, removing mods, changing keybinds, reinstalling Create, and searching for fixes that did not exist, I ended up making a tiny fix mod myself just to restore my sanity.

So if this bug was driving you crazy too — you're welcome.
