Accurate Fast Block Placement

Accurate Fast Block Placement is a client-side NeoForge mod for Minecraft 1.21.1 that makes holding right click feel much more consistent when placing blocks quickly.

Instead of relying on perfectly timed clicks, the mod watches your current block target and sends normal placement attempts when your crosshair moves to a fresh block. The result is smoother fast placement for building rows, bridges, walls, and other repeated block patterns.

Features

• Hold right click to place quickly without needing to manually time every click.
• More accurate fast placement when moving your crosshair across new block targets.
• Client-side only behavior using normal block-use actions.
• NeoForge 1.21.1 support.
• Lightweight implementation with no added blocks, items, commands, or world data.

Client-Side Only

This mod only needs to be installed on the client.

Multiplayer

• The server does not need to install this mod.
• The mod sends regular placement attempts from the client.
• Some servers may consider fast placement helpers against their rules, so check server rules before using it.

Singleplayer

• Works in singleplayer the same way it works on a client.
• No world conversion, datapack, or server setup is required.

How It Works

When you hold the use key, usually right click, the mod checks the block your crosshair is targeting after Minecraft updates the hit result. If the target is fresh and your held item is a block, it performs a normal startUseItem placement attempt at the right time.

This approach is intended to replicate the feel of Accurate Block Placement style mods while being built for NeoForge 1.21.1.
