About This Documentation

These docs were generated with AI assistance and are continuously improved.

Your buildings have enemies! Here's what can hurt them.

Every hazard below is a config setting. They're all on by default, and your server admin can turn any of them off.

💥 Explosions (TNT & Creepers)

BOOM! Explosions are the scariest thing for buildings.

  1. Direct hit — blocks are destroyed.
  2. Nearby blocks — get cracked and weakened.
  3. Weakened blocks — might collapse on their own a moment later.

Tough blocks (obsidian, netherite, deepslate) shrug off blasts. Glass and sand shatter easily.

Watch Out!

A creeper near your house can weaken walls without destroying them. They may come down on their own.

🔥 Fire

Fire slowly cooks your building.

A flammable block touched by flame chars away fast. Any block next to fire or lava heats up slowly — so a long enough fire can even cook a stone or metal frame down.

Block How Fast It Weakens
Wood, wool, leaves Super fast — burns away
Stone, brick Very slow
Iron, copper Slow (heats up, loses strength)
Obsidian, netherite Almost fireproof

Put it out!

Water and rain extinguish fire. A fire with nothing flammable next to it (like a flame on bare stone) has no fuel and burns out on its own after about 30 seconds. Keep the fire fed and it'll keep eating the wall.

🏹 Projectiles (Arrows, Fireballs, Ram Strikes)

Flying things damage walls by their kinetic energy — how heavy and how fast they are.

Light arrow:
🏹 ──────→ *crack* [WALL]   (tiny scratch)

Heavy trident / fireball:
●═════════→ *SMASH* [WALL]  (punches through!)

Faster + heavier = more damage. A slow arrow barely scratches; a fast trident bores in.

One projectile, one hit

A projectile only damages a wall once, when it lands. An arrow stuck in a block just sits there — it does not keep chipping away. Want more damage? Fire more shots. Ten light hits can break a wall that one can't.

Hits don't always resolve the same instant they land — during a heavy volley, the server may settle them a tick later so it never freezes. You won't notice in normal play.

🌧️ Weather

Mother Nature can hurt your buildings too. Only blocks with open sky above them are affected — interiors are safe. Weather effects arrive over a few seconds, not all at once.

Rain ☔

Rain makes exposed blocks 5% weaker while it's falling. Usually not a big deal — but a structure already at its limit can tip over.

Thunder ⛈️

A thunderstorm makes exposed blocks 12% weaker, and lightning can send a random stress spike through a building.

Thunder is dangerous

A building that's already stressed can collapse in a thunderstorm.

Snow ❄️

In cold biomes, snow piles up on exposed blocks and slowly adds weight, up to about 30% of a block's capacity. A flat roof in a snowy place can sag and fall.

Stay safe from snow

  • Build sloped roofs so snow can't pile up.
  • Clear the snow off now and then (removing the snow above relieves the load).

🧍 Standing on Weak Floors

You and every mob have weight. Standing on an already-weak block can be the last straw.

   🧍 You (weight: 2.0)
    ↓
   [Cracked Floor]  ← already heavily loaded

   load + your weight = TOO MUCH → 💥

Healthy floors don't care

Your weight only matters on a block that's heavily stressed (70%+) or already damaged (50%+). Walking on a healthy floor is completely safe.

🪂 Falling From High Up

Jumping onto a weak floor from height hits much harder than walking — the impact grows with how far you fall.

Fall Distance Effect on a weak floor
Under 2 blocks Ignored
2–5 blocks Might break it
10 blocks Probably breaks it
20+ blocks Almost certainly breaks it

Like standing weight, this only affects floors that are already weak. A healthy floor takes the landing fine.

📦 Heavy Storage

A full chest, barrel, or shulker box is heavy. The block it sits on holds that weight, just like a floor holds you.

   📦 Full chest (heavy!)
   ───────────────────
   weak floor block
   ───────────────────
   load + chest weight = TOO MUCH → 💥

An empty chest barely weighs anything. The more loot you pile in, the heavier it gets — a chest packed to the brim weighs the most.

[!TIP] Like standing weight, this only matters on a block that's already weak (70%+ stressed or 50%+ damaged). A heavy chest on a healthy floor is totally fine. But don't stack a full chest on a cracked floor over a long drop!
