⚙️ Utility Core Admin

Server administration utilities for Minecraft servers.

---

Overview

Utility Core Admin provides essential server administration utilities for Minecraft servers. All features are individually toggleable via config/utility_core_admin-common.toml (or the in-game mod menu).

Features

Spawn Schematic

• Pastes a Sponge/WorldEdit .schem structure at world creation (X=0, Z=0)
• Configurable height placement: SURFACE (aligns to highest ground block + offset) or FIXED (absolute Y)
• Includes basic lobby schematic embedded; supports external file at utility_core/spawn_schem/schematic_spawn.schem
• Sets world spawn inside structure
• Permanent build protection (blocks, explosions) + optional mob spawn prevention
• Runtime toggle: /utilitycore spawnprotection on|off|status

Automatic Chunk Pre-generation (ChunkGen)

• Generates chunks in spiral from (0,0) when server is empty
• Duty cycle: configurable load seconds / rest seconds (wall-clock)
• Pauses automatically when players join (configurable)
• Persists progress to disk (utility_core/chunk_pregen/utility_core_chunk_gen.json)
• Independent per dimension: Overworld, Nether, End
• Commands: /utilitycore chunkgen status|start|pause|stop|reset

Server Rules Enforcement

• Applies game rules from utility_core/server_rules.json on server start
• Idempotent: only changes rules that differ from config
• Format: { "rules": { "ruleId": "value" } }
• Command: /utilitycore rules apply|status

Data Pack Folder Loader

• Auto-loads all datapacks (.zip or folders) from <game-dir>/datapacks/ into every world
• Works on dedicated servers and single-player
• No per-world enabling needed

Configuration

Via utility_core_admin-common.toml:

# Spawn Schematic
enableSpawnSchematic = false
spawnSchematic.heightMode = "SURFACE"
spawnSchematic.surfaceOffset = 70
spawnSchematic.fixedY = 64
spawnSchematic.preventMobSpawns = true
spawnSchematic.protectionEnabled = true

# ChunkGen
chunkGen.enabled = false
chunkGen.chunksPerTick = 100
chunkGen.maxRadius = 0
chunkGen.runWithPlayers = false
chunkGen.dimensionOverworld = true
chunkGen.dimensionNether = false
chunkGen.dimensionEnd = false
chunkGen.loadSeconds = 600
chunkGen.restSeconds = 300

# Data Pack Folder
dataPackFolder.enabled = false
dataPackFolder.path = "datapacks"

---

Spawn Schematic File

• External: Place at utility_core/spawn_schem/schematic_spawn.schem (takes priority)
• Embedded: Basic lobby included in mod resources
• Format: Sponge Schematic v2/v3 or legacy WorldEdit (Materials=Alpha)

---

Requirements

Requirement	Version
Minecraft	26.2 (1.21.1)
NeoForge	26.2.0.37-beta+

Important: Set pause-when-empty-seconds=-1 in server.properties so the server doesn't pause while empty.
