AirPlace

A precision building aid for players who are tired of eyeballing floating structures.

Press a hotkey and every placeable spot in the space around you lights up red. Look around, and whichever one you're aiming at turns green — that's exactly where your next block will land. Right-click to place it, no supporting block required.

Whether you're building a floating island, a detached bridge span, or fine-tuning a tricky diagonal, AirPlace shows you the grid before you commit.

Features

• 🎯 See before you place — the exact target cell is always highlighted, so there's no more guessing whether your crosshair lines up
• 🧱 Place in open air — no need for scaffolding, water, or temporary blocks to place against; works in true air
• ⌨️ Rebindable hotkey — toggle or hold mode, your choice, changeable from Options → Controls
• ⚙️ Fully configurable — workspace size, targeting reach, strict-air-only mode, and outline colors all live in the config file
• ✅ Survival-friendly — consumes items, plays placement sounds, and fires advancements exactly like a normal placement
• 🔒 Server-safe — every placement is re-validated server-side, so it respects build permissions, spawn protection, and claim plugins/mods

How it works

A configurable-size workspace (5x5x5 by default) stays centered on you. Every replaceable air cell inside it outlines in red; the one your crosshair is on turns green. Right-click with a block in hand to place it there.

Configuration

Found at config/airplace-common.toml after first launch:
