Changelog

Version: 2.1.2
Date: 2026-08-26

  Features:
    - Every radar looks around itself now. Its spiral is centred on the chunk it stands on, so a radar far from the base opens the map near that radar instead of the map near the map origin.
    - A chunk that the radar generated for nothing is deleted again, so looking for ore does not grow the save file. The chunk is kept when any force has charted it or has anything built there, and chunk generation depends only on the map seed, so walking there later gives the same map.
    - Added a setting to keep those empty chunks instead of deleting them.
    - The map generator requests, the deletions and the cleanup of the lists now run in a background worker that does one single step per tick. The worker is only subscribed while it has something to do, an idle game pays nothing.
  Bugfixes:
    - Fixed that a radar of one force could take a chunk away from another force: the list of chunks belongs to a single radar now, and only the force of that radar decides whether a chunk counts as revealed. Whether a chunk may be deleted still asks every force.
    - Fixed that every radar of a surface shared one spiral, so a second radar continued the walk of the first one instead of searching its own surroundings.
    - Fixed that a radar on a space platform kept walking its spiral and asking the map generator for chunks. A platform holds no resources, the radar does nothing there now.
    - Fixed that a radar which was moved to another surface kept working on the old one. It follows its entity now, and a new place starts a new spiral.
    - Fixed that clearing a surface left the spiral in the middle of its walk instead of starting over.
    - Fixed that a scan could walk through a long row of dead entries in one go. It drops at most four of them now and hands the rest to the worker.
    - Fixed that the check for resources used the full chunk box, which touches the first tile of the next chunk, so a chunk next to a patch could count as a patch itself.
  Changes:
    - The chunk positions are stored instead of the bounding boxes of the chunks.
    - A new radar starts with what another radar of the same force on that surface knows already.
    - The data of a radar is dropped when it is mined or destroyed.

Version: 2.1.1
Date: 2026-08-25
  By:
    - darkfrei
  Features:
    - A scan that has nothing left to reveal now asks the map generator for the next point of a phyllotaxis spiral, so the radar keeps opening new map instead of going idle. One of the following scans reveals what was found there.
    - Added a runtime setting for the size of that spiral, the distance between its points, six chunks by default.
    - A spiral point that is generated already is checked right away, so the radar also works in a save where it was added later.
  Bugfixes:
    - Update to Factorio 2.0 and 2.1: the mod stored its data in the removed global table, the recipe used the removed result field and the short ingredient form, and the entity repeated graphics of 1.1 that no longer exist.
    - Fixed that a mined out chunk was removed from the wrong table, so it stayed in the list forever and kept wasting scans.
    - Fixed that a chunk which was revealed already could be picked again instead of an unrevealed one.
    - Fixed that the data of deleted surfaces was kept forever, and that surfaces were tracked by name instead of by index.
  Changes:
    - The entity is now a copy of the radar of the game, so it follows its graphics instead of repeating file names.
    - The radar of the game is no longer fast replaceable by the ore radar.
    - On a limited map the spiral stops once the map is covered.
