Changelog

Version: 0.3.29
Date: 2026-03-15
  Fix: define rotated-layer direction-count normalizer at file scope so patrol boat graphics patching does not crash during data stage.

Version: 0.3.29
Date: 2026-03-15
  Fixes:
    - Fixed patrol boat cargo-wagon rotated sprite layers so every layer uses the same direction_count.
    - Normalized copied and stripped patrol boat rotated layers after applying custom graphics to prevent prototype load failure.

Version: 0.3.28
Date: 2026-03-15
  Fixes:
    - Fixed patrol boat prototype load error caused by mismatched animation layer max_advance values.
    - Kept stripped patrol boat overlay layers animation metadata in sync to prevent duplicate ghost rendering after entering the vehicle.

Version: 0.3.27
Date: 15. 03. 2026
  Bugfixes:
    - Fixed Patrol Boat custom graphics duplicating visible animation layers after entering the vehicle.
    - Cleared inherited tint/mask-style overlay state from Patrol Boat custom sprites to stop the semi-transparent ghost split.

Version: 0.3.27
Date: 14. 03. 2026
  Bugfixes:
    - Fixed Aircraft Carrier hidden power pole startup compatibility when another mod adds a substation upgrade chain.
    - Cleared inherited upgrade metadata from the hidden carrier power pole so Factorio 2.0 no longer rejects it as non-minable.

Version: 0.3.25
Date: 12. 03. 2026
  Features:
    - Added the Aircraft Carrier ship type with two mounted roboports and a long-range delivery landing pad.
    - Aircraft Carrier roboports now draw power from ship fuel even while the ship is stationary.
    - Increased Aircraft Carrier roboport range to 10x vanilla and moved the two roboports into a forward inline deck layout.
    - Aircraft Carrier deck attachments now use visual proxies drawn above the hull so roboports and the landing pad stay visible in every ship orientation.
    - Increased Aircraft Carrier roboport charging throughput, expanded onboard roboport battery capacity, and added exhaust smoke while the ship is generating electric power.
    - Improved Aircraft Carrier generator fuel efficiency by 10x and restricted electric generation fuel draw to the ship engine burner inventory instead of the cargo hold.
  Compatibility:
    - Added a hard dependency on Long range delivery drones (fork) and expect the fork patch that tracks moving carrier landing pads via live entity positions.

Version: 0.3.24
Date: 01. 03. 2026
  Bugfixes:
    - Fixed patrol boat rail variant graphics setup so the waterway cargo-wagon now uses a valid rotated sprite definition derived from the independent boat.
    - Hid the Patrol Boat missile turret more completely by stripping additional Factorio 2.0 turret render fields (`folding_animation`, `graphics_set`, `water_reflection`).
  Improvements:
    - Patrol Boat placed on waterways now matches the independent Patrol Boat visual style more closely.

Version: 0.3.23
Date: 26. 02. 2026
  Bugfixes:
    - Fixed accidental global `is_stopped` function declaration in runtime control logic.
  Improvements:
    - Reduced patrol turret runtime sync work by skipping position/direction resync when the patrol boat has not moved.
    - Throttled patrol turret force resync similarly to battleship turrets to lower per-tick overhead.

Version: 0.3.22
Date: 25. 02. 2026
  Improvements:
    - Reduced Patrol Boat escort movement step size to smooth out visible teleport jumps.
    - Heavy escort loop no longer directly moves escort boats; movement is handled by the per-tick visual escort step.
    - Kept heavy escort loop for avoidance calculations and cached offsets only.

Version: 0.3.21
Date: 25. 02. 2026
  Improvements:
    - Patrol Boat escort movement now performs a light follow step every tick for smoother motion behind Battleships.
    - Heavy escort logic (avoidance/path decisions) remains throttled; avoidance vector is cached and reused between updates.
    - Avoided double movement on heavy escort ticks by skipping visual escort step on those ticks.

Version: 0.3.20
Date: 25. 02. 2026
  Improvements:
    - Applied runtime rendering proxy visuals to Patrol Boat missile turret (smooth attachment during movement).
    - Moved Patrol Boat turret sync to the visual tick loop (every tick) while keeping ammo/radar logic throttled.
    - Added Patrol Boat proxy cleanup on destroy/invalid entity paths.

Version: 0.3.19
Date: 25. 02. 2026
  Improvements:
    - Replaced visible Battleship artillery entities with a runtime rendering proxy (smooth visual attachment during movement).
    - Real artillery turrets remain active as hidden logic entities (ammo, targeting, firing behavior preserved).
    - Added defensive rendering API fallbacks to avoid crashes on incompatible setups.

Version: 0.3.18
Date: 25. 02. 2026
  Improvements:
    - Split Battleship turret visual sync from heavy maintenance logic: turret attachment now updates every tick, while maintenance stays throttled.
    - Improved Battleship artillery turret attachment smoothness on cargo ships by syncing to sub-tile positions at runtime.
    - Added safe fallback to 0.5-tile snapping when a surface/entity refuses exact teleport (compatibility mode).
    - Battleship artillery turrets now attempt to sync direction with ship turns for better visual alignment.

Version: 0.3.17
Date: 21. 02. 2026
  Improvements:
    - Switched tuning settings from runtime-per-user to runtime-global (per map).
    - Added map-wide tuning cache in control.lua for lower runtime overhead.
  Bugfixes:
    - Hardened cargo-ships remote interface registration (safe add_ship/add_boat checks).
    - Fixed undefined player fallback in patrol escort assignment path.
    - Stopped mutating base cargo_ship prototype when tinting independent battleship visuals.
    - Added missing English locale entries for battleship-debug-global.

Version: 0.3.16
Date: 20. 02. 2026
  Features:
    - Added runtime-per-user tuning settings for patrol follow, escort behavior, ammo refill, radar charting, and force sync.
  Bugfixes:
    - Applied tick-based throttling for ammo refills and escort updates (configurable per player).
