Encumbering stone

Once a stone is activated, the player stops picking up items from the world. Items that are on the exception list still get picked up, so a player can keep specific items flowing into the inventory. Activation happens by right-clicking with the stone in hand, and holding Shift while right-clicking opens the screen for managing exceptions. The mod is described as a Terraria-inspired encumbrance mechanic, and it changes how far a player can carry before the inventory takes priority.

Stones can be stacked and crafted in quantity, and each extra stone in the inventory makes the player heavier, slowing movement by 50 percent per stone until the player stops moving entirely. Stones can also be placed in a hopper, where they stop the hopper from picking up and passing items, with exceptions still applied. The mod runs on Fabric and needs Fabric API. It is client and server, so both the server and every player need it. Files cover game versions 1.21 – 26.2 and are released under All rights reserved, so the mod is not open source, although its source code is publicly available.
