Changelog

Version: 0.0.10
Date: 2026-10-08
  Bugfixes:
    - Flyers could not be picked as priority targets in regular turrets: the turret only lists what it can attack, and flyers in the air are only for anti-air. Regular turrets now list the flyers (on the ground), and anti-air turrets keep listing them as before. Picking one still covers every state of that flyer the turret can hit.

Version: 0.0.9
Date: 2026-10-05
  Bugfixes:
    - Flyers placed by a player (for example from the map editor) were never handled by the mod: in the air they never landed, so no turret could ever hit them. They are now handled like any other flyer, and the ones already in a save are picked up when the mod updates.
    - Flyers attacking something big (a turret, a nest) now count it as close by its edge, not its centre, so they land to attack it sooner.

Version: 0.0.8
Date: 2026-10-04
  Bugfixes:
    - The capture robot rocket still could not target flyer nests when fired by a player, a rocket turret or a spidertron (only biter and spitter spawners were valid targets). Flyer nests are now valid targets too.

Version: 0.0.7
Date: 2026-10-04
  Features:
    - Captive flyer spawner: the capture robot rocket (Space Age) now works on flyer nests and turns them into a captive flyer spawner, with its own graphics (the flyer nest held by the capture machinery, with its working animation). It works like the captive biter spawner: it needs food and lays biter eggs. If it starves, it becomes a wild flyer spawner again.
  Bugfixes:
    - Flyer nests could not be captured with the capture robot rocket.

Version: 0.0.6
Date: 2026-10-04
  Bugfixes:
    - Hardened the flyers against cases like the 0.0.5 crash: their attack group or target changing or disappearing during a landing or take-off, the game not placing the flyer back, or the enemy force being removed by another mod. In all of them the flyer now carries on (or is dropped quietly) instead of stopping the game. Also turret target priorities set by another mod in an unexpected way.

Version: 0.0.5
Date: 2026-10-04
  Bugfixes:
    - Fixed a crash when a flyer was taking off on its way to something that was destroyed meanwhile (for example a nest being destroyed). It now just carries on with its own orders.

Version: 0.0.4
Date: 2026-10-03
  Bugfixes:
    - Fixed a crash when a flyer in the air was hit by something that can't be attacked, such as the explosion from another mod's anti-air shells. Flyers now only chase what they can attack.

Version: 0.0.3
Date: 2026-10-02
  Graphics:
    - The flyer nest has new graphics, closer to the game's own nests: its colour, the darker inside of its openings, and its shadow (now right under it). Its death animation too.

Version: 0.0.2
Date: 2026-09-29
  Changes:
    - Flyer nests are now added next to existing enemy bases instead of taking the place of a vanilla nest. The map is generated exactly as without the mod, and removing the mod leaves every enemy base with its vanilla nests (no gaps).
    - Adding the mod to a game in progress: flyer nests are added once to the existing enemy bases, far from the start and never within 50 tiles of anything built by a player.
    - Newly generated map areas and bases founded by enemy expansion also get flyer nests.

Version: 0.0.1
Date: 2026-09-29
  Features:
    - Flyers: flying biters in four evolution tiers (small, medium, big, behemoth), in the vanilla art style.
    - They fly straight over walls, water and cliffs; they land when they wait, walk around their spot and fight on the ground, with their own take-off and landing animations.
    - While flying they can only be hit by turrets that declare they can shoot at air targets. On the ground every turret can hit them. If an anti-air turret shoots one, it flies to that turret, lands beside it and attacks it.
    - Flyer nest: a new enemy spawner, mixed into enemy bases a bit further from the start. Its flyers hatch airborne.
    - Turret priority lists: pick a flyer once and it counts both in the air and on the ground.
  Modding:
    - To make a turret able to shoot flyers in the air, add "flying-robot" (or "air-unit") to its attack_target_mask in data.lua or data-updates.lua.
