Building Shift

Holding Shift normally stops a click on a functional block from opening its interface, which gets in the way when a builder wants to place a block against one. Building Shift cancels that interaction without the key, and a toggle bound to G by default switches the behavior from the controls menu. A sound plays after each placed block, and a row of rapidly placed blocks no longer produces repeated spam in the way it does in vanilla.

The mod shows a small indicator beside the crosshair so the player can see which placement state is active. Placement depends on which side of a block is targeted and on the direction the player is facing, and the mod keeps those values in step with the world. Fabric API is required, and the mod is published for Fabric and Quilt only, across seven release versions in the 1.20 – 1.21.1 range. The latest files, 1.2.0 for 1.21.1, date from 2024-09-01.

The mod works on either side, and neither the server nor the client needs it. Installing it on both sides gives the fullest set of features, while a client that joins a server without the mod can still use the client-side parts through a command. Some minor bugs related to missing client-side code are known, and the Known bugs section of the project lists them. The license is a custom one, and the code is not open source, though the source and an issue tracker are public.
