Utility Nexus Admin

v0.0.0-beta.3 - Chunk Pregeneration System

Added

• Chunk pregeneration system with progress persistence — pregenerates chunks when no players are online
• Commands: /una pregen start, stop, pause, resume, status
• Configuration commands: /una pregen config enabled <0|1>, center <x> <z>, radius <value>, chunksPerTick <1-200>, dimension <namespace:id>
• Auto-pause when players join, auto-resume when last player leaves — runs only on empty server
• Progress saved to utility_nexus_admin/pregen_progress.json — persists across server restarts
• Configurable center (default 0,0), radius (0 = infinite), chunks per tick (default 50), target dimension
• Logging every 30s with chunks generated, current position, percentage complete

Technical Changes

• ChunkPregenerator — Core pregeneration engine with async chunk generation
• PregenerationCommand — Brigadier command implementations
• Progress tracking with PregenerationProgress (generated chunks, current position, dimension)
• Uses targetLevel.getChunk() for chunk generation with ChunkStatus.FULL
• Event handlers: PlayerLoggedInEvent (pause), PlayerLoggedOutEvent (resume), ServerTickEvent.Post (generate)

Configuration

Default config at config/utility_nexus_admin.toml:

• pregen.enabled = false — Enable/disable pregeneration
• pregen.startX = 0, pregen.startZ = 0 — Center chunk coordinates
• pregen.radius = 0 — Radius in chunks (0 = infinite)
• pregen.chunksPerTick = 50 — Chunks generated per server tick
• pregen.dimension = "minecraft:overworld" — Target dimension

Progress File

Saved at utility_nexus_admin/pregen_progress.json (game directory root):

• Generated chunks list with coordinates
• Current chunk position for resume
• Last updated timestamp
• Dimension, center, radius settings
