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
.schemstructure 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.jsonon 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 (
.zipor folders) from<game-dir>/datapacks/into every world - Works on dedicated servers and single-player
- No per-world enabling needed
Commands
/utilitycore chunkgen status|start|pause|stop|reset
/utilitycore rules apply|status
/utilitycore spawnprotection on|off|status
/utilitycore help
