Civillis

The land remembers your presence.

Where players build, monsters yield.

What is Civillis?

Have you ever wished your base just _felt_ safe — without flooding every surface with torches or carpeting the ground with slabs?

Civillis makes that happen. It recognizes the signs of civilization you naturally create — a campfire burning, a bed placed, a workbench humming — and silently pushes hostile mobs away. The more your settlement grows, the stronger the protection. No commands, no rituals, no new mechanics to learn — just play, and the land responds.

Leave for too long, and nature slowly reclaims its ground. But a well-established city never truly falls.

How It Works

The mod evaluates a 240×240×48 block area (configurable) around each potential spawn point and computes a civilization score based on nearby structures. Blocks that reflect human presence — furnaces, beds, campfires, beacons, workstations, and others like them — are what the mod looks for.

• Settle and grow → safer land. A thriving city can push monsters back ~90 blocks from its borders.
• Leave for a while → gradual decay. Over time without visits, protection weakens — but a large settlement still keeps a ~40-block safe perimeter.
• A small cabin → modest protection. A lone outpost won't create a fortress, but it helps.

_That's millions of blocks evaluated per spawn attempt — and it happens every time, everywhere in the world. See the Wiki to learn how the shard-based civilization engine keeps this at constant time._

Features

The blocks you already use to build your world are what keep you safe. Campfires, beds, furnaces, crafting tables — the things that make a place feel _lived in_ — are exactly what the mod looks for. Build the home you've always wanted, and safety follows.

Hostile mobs inside civilized zones try to leave. In normal situations they drift toward less civilized ground, and in highly civilized city centers they may even give up fighting and retreat. This behavior follows your suppression settings and gives settlements a more believable defensive feel.

The world doesn't stay tamed forever. Unvisited areas gradually lose their protection over time, creating a living, breathing sense of territory that rewards active presence. Offline time in singleplayer doesn't count — your civilization picks up right where you left off.

Want a mob farm in the heart of your city? Build the structure to carve out a pocket of open wilderness inside your civilization. Mobs spawn freely within it, ignoring the surrounding score. Place mob heads inside to attract specific types. _Hint: crying obsidian, a soul campfire burning on top, and a bone to sacrifice._

Scan your local civilization level with a sonar pulse. Carry a portable detector (compass + emeralds) for quick on-the-go checks, or place a bell on a lodestone for a more powerful stationary sweep. Color-coded boundaries and custom sound cues tell you exactly how safe (or exposed) your surroundings are.

In high-civilization areas, you can build a small altar and activate it with a totem to create a one-time emergency revival point. If death would occur, you're pulled back to the podium and revived with totem-style effects (regeneration, absorption, and fire resistance) without consuming a totem in hand.

Civillis is built to be tuned by datapacks. Block weights, mob-head attraction lists, zone and dimension policies, and spawn-gate entity lists all load from data files, so packs can reshape how civilization behaves without code. Modpack authors can also assign custom blocks to tiered tags like #civil:high_civilized or #civil:low_civilized to give whole groups of blocks a civilization weight at once.
