Accurate Fast Block Placement
by Luc1fer1o
Accurate Fast Block Placement makes holding right-click place blocks more consistently, without requiring precisely timed clicks.
What it does
While the use key is held, the mod checks which block the crosshair targets after each Minecraft update to the hit result. When the target changes to a fresh block and a block item is held, it sends a normal placement attempt at the right moment, so repeated placement stays smooth. The approach aims to reproduce the feel of earlier Accurate Block Placement style mods built for NeoForge 1.21.1.
Building rows, bridges, walls or other repeated block layouts is where the mod helps most, because the crosshair can sweep across fresh targets while placements keep going. Only the client needs the mod. Accurate Fast Block Placement uses the normal block-use actions, so the server receives regular placement attempts and needs no changes of its own. Some servers treat fast placement helpers as restricted, so the server rules should be checked before use. The mod is released under All rights reserved and is not open source.
Key features
Consistent held placement
Holding right-click places blocks at a steady pace, without the player timing each click.
Target tracking
The mod watches the block under the crosshair and places onto each new target as the crosshair moves.
Normal block-use actions
Placements go through the standard item use path, so they behave like ordinary clicks on the server.
Lightweight design
The implementation adds no new blocks, items, commands or world data.
