Steam Deck Native Controls for Minecraft (Java Edition)

This mod gives Minecraft Java Edition native support for the Steam Deck's inputs, bypassing all of Steam Input.

Features

• Gyro and flick stick camera controls as designed by Jibb Smart
• Twin-stick aiming using left joystick and right trackpad
• Mouse controls for GUIs
• On-screen keyboard using trackpads

Installation

This is a Forge mod. Place the JAR in the mods/ directory.

You will also need to configure Steam Input to use an empty configuration in order to avoid conflicts.

Touchscreen

In order to enable this mod's touchscreen controls, you need to create a file /etc/udev/rules.d/51-deck-touchscreen.rules with contents

SUBSYSTEMS=="input", ATTRS{name}=="FTS3528:00 2808:1015", ATTRS{phys}=="i2c-FTS3528:00", RUN="/usr/bin/setfacl -m u:deck:rw %N"

How it works

This mod opens the Steam Deck's hidraw device and reads raw input reports (independently / in parallel with anything Steam does). These inputs are injected into Minecraft by calling into the existing keyboard and mouse handler code.
