Plan-first chunk pre-generation for Paper 1.21.11 — shows what will generate before it starts.

FastWorldGen 1.0.0

Initial release.

  • Plan-first pipeline: /fwg plan shows total chunks, existing chunks, chunks to generate, and region count before any generation happens.
  • /fwg start begins generation immediately after planning; works with just a world name (uses a configurable default radius) or explicit radius/bounds + optional center.
  • Existing chunks are skipped by default; pass --fresh to force regeneration.
  • Work is grouped into 32×32 chunk regions and batches, ordered for spatial locality.
  • Adaptive throughput throttles generation based on live server tick time (MSPT).
  • /fwg status shows live progress, speed, ETA, region/batch counts, and MSPT.
  • Detailed logging: per-region and per-batch completion lines as generation runs, plus a full summary (chunks generated/failed, elapsed time, average speed) when a job finishes.
  • /fwg pause / /fwg resume / /fwg cancel, all graceful — in-flight chunk operations are allowed to finish rather than being interrupted.
  • Job state survives server restarts; the world is re-inspected on startup rather than trusting stored progress.
  • Full permission set, all defaulting to op.

Requirements: Paper 1.21.11, Java 21+.
