Changelog

Version: 0.1.6
Date: 2026-04-13
  Optimisations:
    - Removed redundant per-spawner ore proximity check during chunk generation (chunk ore threshold is sufficient).
    - Single unit-spawner type query replaces two separate biter-spawner + spitter-spawner queries.

Version: 0.1.5
Date: 2026-04-13
  Bugfixes:
    - Fixed ore spawners being placed by map generator via inherited autoplace settings. Spawners now only appear via control.lua logic, respecting the 'Allow ore biters on surface' setting.

Version: 0.1.4
Date: 2026-04-12
  Features:
    - Added custom Ember Biter sprites replacing default base game biter appearance.
    - Standalone mode: Ember Biters now spawn on the surface near coal patches when used without Mineshafts mod.
    - With Mineshafts mod: Surface spawning controlled via "Allow ore biters on surface" setting (default off).
    - Mineshafts is now an optional dependency.
  Bugfixes:
    - Fixed sprite loading for multi-file sprite sheets (filenames array support).
    - Fixed circular dependency error when used together with Mineshafts mod.
    - Fixed Factorio 2.0 API compatibility: game.active_mods replaced with script.active_mods.
    - Fixed biters incorrectly spawning on mineshaft underground surfaces.
    - Fixed spawners being replaced far from ore patches. Spawners now only convert when matching ore is within 32 tiles.
