Changelog

Version 5.3.0

- CHANGED: Waves now gather existing enemy units near a lab and command them to attack it,
  instead of finding distant chunks-with-spawners
  * Biters that can actually walk to your base get sent; attacks land more reliably
  * Wave engages anything in its way (distraction = by_anything)
- CHANGED: Wave size formula is now max(3, floor(sqrt(base_points) * 1.5)) * multiplier
  * Smoother scaling from early to late game; sqrt prevents runaway endgame waves
  * base_points = research_unit_count * sum_of_ingredient_amounts
- CHANGED: Search starts at the lab's chunk (was 25 chunks out) and caps at 50 chunks
  (1600 tiles, was 800 chunks). Biters past 50 chunks rarely make it home anyway.
- ADDED: Big waves split into unit-groups of 200 (vanilla soft cap)
- FIXED: Active tasks now persist across save/load via `storage` (was a module local;
  in-flight tasks were lost on save+load and could desync multiplayer clients on join)
- FIXED: Task IDs no longer collide after a task is removed (used #active_tasks + 1)
- PERFORMANCE: on_tick handler is unregistered while idle; mod consumes zero
  per-tick cost when no wave is in flight
- PERFORMANCE: Lab chunk coordinates cached on the task instead of recomputed
  every gather tick
- PERFORMANCE: Per-chunk search area reuses a scratch table instead of
  allocating fresh tables on every find_entities_filtered call
- PERFORMANCE: Skip redundant validity checks on units freshly returned from
  find_entities_filtered (re-validation still happens at dispatch time)
- INFO: Setting key `nest_count_multiplier` is unchanged (so existing saves keep their
  configured value); the display label is now "Wave Size Multiplier"
- INFO: info.json `/n` -> `\n` typo, and dependency `base >= 1.1.0` -> `base >= 2.0.0`
- REMOVED: Dead `math.randomseed` call (mod never used math.random)

Version 5.2.0

- FIXED: Critical bug - was processing attacks per player instead of per surface
  * Research is force-wide, so this caused duplicate attacks (4 players = 4x attacks)
  * Now correctly processes once per surface that has labs
  * Fixes attack scaling issues in multiplayer
- FIXED: Locale files still referenced removed pollution settings (v5.1.0 cleanup)
- FIXED: Settings cache now properly cleared on mod load to prevent stale values
- IMPROVED: Chunk search now starts at radius 25 (800 tiles) to skip cleared base area
  * Significantly reduces time spent searching empty chunks near labs
  * Finds spawners faster and more efficiently
- IMPROVED: Increased max search radius from 300 to 800 chunks (25,600 tiles)
  * Better coverage for large bases and endgame scenarios
  * Research takes ~10 minutes in endgame, so thorough search is prioritized over speed
- IMPROVED: Better validation consistency throughout codebase
- IMPROVED: More explicit nil checks in chunk search initialization
- NOTE: All fixes maintain backward compatibility

Version 5.1.0

- REMOVED: Pollution feature completely removed (obsolete)
- REMOVED: Pollution-related settings (pollution_enabled, attack_pollution_multiplier, flat_pollution_points)
- SIMPLIFIED: Code now focuses solely on triggering biter attacks
- SIMPLIFIED: State machine reduced from 4 states to 3 states (removed POLLUTING_CHUNKS)
- IMPROVED: Cleaner codebase without pollution-related logic
- NOTE: Mod now only triggers attacks, no pollution generation

Version 5.0.1

- CHANGED: Pollution is now disabled by default
- NOTE: Players can still enable pollution in mod settings if desired
- NOTE: Attacks remain enabled by default

Version 5.0.0

- MAJOR: Complete code refactoring and UPS optimization
- PERFORMANCE: Work now processes incrementally over multiple ticks to maintain >55 UPS
- FEATURE: Task queue system for handling multiple concurrent research events
- OPTIMIZATION: Chunk finding limited to 8 chunks per tick
- OPTIMIZATION: Pollution application limited to 10 chunks per tick
- OPTIMIZATION: Attack triggering limited to 2 chunks per tick
- IMPROVED: Better error handling and entity validation throughout
- IMPROVED: Modular code structure with clear separation of concerns
- IMPROVED: More efficient chunk search algorithm
- FIXED: Chunk array caching for attack system to reduce overhead
- FIXED: Surface and entity validity checks during processing
- ARCHITECTURE: State machine-based task processing system
- ARCHITECTURE: Incremental processing prevents UPS drops during large operations
- NOTE: All functionality preserved, now optimized for performance

Version 3.0.0

- STABLE: Final release version
- Added: Separate toggle settings for pollution and attacks
- Added: Comprehensive configuration options
- Improved: Better performance and compatibility
- Fixed: Math.floor() issue in chunk calculation
- Added: Proper locale support for English and German
- Feature: Pollution generation can be disabled independently
- Feature: Biter attacks can be disabled independently
- Setting: pollution_enabled - toggle pollution on/off (default: true)
- Setting: attacks_enabled - toggle attacks on/off (default: true)
- Setting: attack_pollution_multiplier - adjust pollution strength (default: 1.0)
- Setting: flat_pollution_points - add fixed pollution amount (default: 0)
- Setting: nest_count_multiplier - control number of attacked chunks (default: 1)

Version 2.0.0

- FEATURE: Existing enemy units are now grouped and commanded to attack
- COMPATIBILITY: Better mod compatibility with existing game structures
- IMPROVED: No unit spawning - uses naturally generated enemies only
- CHANGED: Attack system now groups existing biters instead of spawning new ones
- PERFORMANCE: More efficient unit gathering and command system
- BALANCE: Attacks scale with naturally available enemy forces
