Offhand Tweaks

Holding a torch, lantern or lamp in the offhand normally places it when a player right-clicks a block. Offhand Tweaks can stop that placement, so right-clicks reach the world for other uses such as opening chests or working machinery. The same switch can block right-click use of shields, food and other item types, and a global option can restrict placement of any unlisted block or item from the offhand slot. Each setting is toggled separately, so a player can keep one interaction while disabling another.

The mod is built for players who want the offhand to stay equipped without accidental effects. Settings can be adjusted from the usual Forge configuration screen, or by opening the config file in a text editor. Each player sets their own preferences, and the settings apply on that player's client. Ghost blocks, fake hand-swing animations and wasted items are the side effects the mod is meant to prevent, and it synchronizes each change with the server through a custom network packet so both sides cancel the event together.

Offhand Tweaks is published for Forge only, for 1.20.1, with 1.1.0 as the latest file. Installation covers the server and each player's game. The code is under the MIT License and is open source.
