BackSlot by Flike
by FlikeID
BackSlot gives Fabric players a back slot for weapons and other items, with a configurable render position and a button to swap items into it.
What it does
The mod draws an item held in the back slot behind the player's body, so a weapon or lantern stays visible while the player uses the hands for other things. Each item's position and rotation can be adjusted with commands, or with buttons while in game. Settings come from four configuration layers, and the client, world, server and player data can each carry additional customization in NBT form.
BackSlot uses the Trinket back slot, so it works alongside other mods that rely on that slot. An active trinket slot lets a button bind replace an item with the one in the back slot, and the render transformation can be copied to another item. Server owners can place the mod in a modpack and adjust item rendering for every player on the server.
The server must run the mod, while players may add it to see items rendered behind the back. Files are published for Fabric only, for 1.20.1, with version 1.1 as the latest file. The mod is released under the GNU Lesser General Public License v3.0 or later and is open source, with public source code, an issue tracker and a wiki.
Key features
Back slot rendering
Items placed in the back slot are drawn behind the player, with a fixed vertical offset so armor does not clip them.
Adjustable transformations
Commands and buttons change the position and rotation of each rendered item, and custom transformations can be set for individual items.
Active slot binding
A button bind can swap the held item with the item in the active back slot.
Russian and English text
Interface text is available in Russian and English.
