Auto Surround

Hold one key -> obsidian around your feet. Release -> your weapon is back in your hand.

Auto Surround is a lightweight client-side Fabric mod for crystal PvP and anchor PvP. While you hold the key (default J) it keeps the four blocks around your feet filled with obsidian and instantly re-places anything that gets blown up – the classic surround / self-trap, as a small standalone mod instead of a hacked client.

Features

Hold to surround – places up to 4 blocks per tick and keeps refilling broken blocks for as long as you hold the key
Edge-aware – standing on a block edge? It surrounds all 2-4 blocks your feet overlap, not just one
Floor fill – puts a block under you when the floor is missing (can be turned off)
Optional head layer – full 2-block self-trap with one config switch
Silent swap – switches to obsidian, places, and gives you back exactly the item you were holding; no visible hotbar flicker
Inventory pull – no obsidian in the hotbar? It takes it from your main inventory and puts it back afterwards
Safe placing – never right-clicks respawn anchors, beds, chests, doors, buttons… while placing, so it can’t blow up an anchor in your face
Silent rotations – tells the server where it "looks" for every placement, which most anti-cheats expect
Lightweight – client-side only, Fabric API is the only dependency, no HUD clutter

How to use

Carry obsidian anywhere in your inventory.
Hold J (rebind in Options -> Controls -> Auto Surround).
Let go to instantly get your sword / crystal / totem back in hand.

Configuration

Everything lives in config/autosurround.json and can be changed in game:

/autosurround – show current settings and how much obsidian you carry
/autosurround below <true/false> – also fill the block under your feet (default: true)
/autosurround headlayer <true/false> – also surround at head height, full 2-block trap (default: false)
/autosurround blockspertick <1-16> – blocks placed per game tick (default: 4)
/autosurround delay <0-20> – ticks to wait between placement bursts (default: 0)
/autosurround rotate <true/false> – send silent look packets towards each placement (default: true)
/autosurround inventory <true/false> – pull obsidian from the main inventory (default: true)
/autosurround notify <true/false> – action-bar warning when you run out (default: true)
/autosurround blocks add <id> – add fallback blocks, e.g. ender_chest or crying_obsidian (default: obsidian only)
/autosurround blocks remove <id> / /autosurround blocks reset – manage the block list
/autosurround reload – reload the JSON file

Compatibility

Minecraft 1.21.8 – 1.21.11, Fabric Loader 0.16+, Fabric API, Java 21
Client-side only – nothing to install on the server
Works great together with Auto crystal PVP and Auto-Anchor (same author – see my other projects)

Notes

Automated block placement counts as a macro on many PvP servers and may be bannable – check the rules of the server you play on and use at your own risk. If a strict anti-cheat rolls your blocks back, try /autosurround blockspertick 2 and /autosurround delay 1.
