HotbarReplace (Unofficial port)
by rinke
HotbarReplace refills a hotbar slot from the inventory once the block placed from it runs out, using a block of the same type.
What it does
When the last block in a hotbar slot is placed, the slot is topped up with another block of the same type taken from the inventory, so building can continue without reaching into the inventory screen. The mod is an unofficial port of the original project, and its source code is public. It is a client-side only mod, so only the player's client needs it, and it is published for Fabric alone under the MIT License, which makes it open source. Files cover 1.21.6 – 26.2 across 10 release versions, and the latest Fabric file is 1.26.1 for 26.2.
Key features
Hotbar refill
A hotbar slot holding placeable blocks is refilled from the inventory when its last block is placed.
Same-type matching
Only blocks of the same type are used to refill the slot, so the hotbar keeps its current block.
Inventory-based supply
The refill is taken from the player's inventory, letting a long build continue with no manual reloading.
