Replaced static entity lists (e.g., HullList, GapList, MapEntityList, etc.) with thread-safe copy-on-write wrappers to improve concurrency and prevent race conditions. Updated usages and related methods to support the new thread-safe collections, ensuring atomic operations and lock-free reads throughout the codebase.
Refactored multiple components to defer Farseer physics transform operations using PhysicsBodyQueue, preventing unsafe calls from parallel contexts. This change addresses thread safety issues with Farseer's DynamicTree and ensures transforms are executed in a safe context. Also increased the spawn amount limit in DebugConsole from 100 to 100000.
Introduces a thread-safe queue for deferring physics operations (such as body creation and transforms) to the main thread, ensuring Farseer Physics is not accessed from parallel contexts. Updates Holdable, Item, MapEntity, and GameScreen to use the new PhysicsBodyQueue for safe physics operations during parallel updates, and refactors PhysicsBodyQueue to support general deferred physics actions.
Introduces PhysicsBodyQueue to safely defer physics body creation to the main thread, addressing thread-safety issues with Farseer Physics during parallel updates. Updates LevelResource, TriggerComponent, BallastFloraBehavior, and MapEntity to use the queue for all physics body creation and refresh operations, ensuring they are processed outside of parallel loops. Also adds cleanup of the queue at round end.
Refactored various collections (lists, dictionaries, queues, and caches) in AI, character, animation, and item component systems to use thread-safe patterns and concurrent data structures. This includes introducing copy-on-write wrappers, ConcurrentDictionary, ConcurrentQueue, and ThreadLocal where appropriate to ensure safe concurrent access and mutation, improving stability in multi-threaded scenarios.
Replaced static lists and dictionaries with thread-safe ConcurrentDictionary or ThreadLocal collections for various item components and systems. Updated all relevant code to use snapshots (ToArray, ToList) for safe iteration, and added helper methods for marking and clearing changed connections. These changes improve thread safety and prevent potential concurrency issues in multi-threaded scenarios.
Replaces static Item.ItemList and related collections with thread-safe data structures using ConcurrentDictionary and ImmutableHashSet. Adds thread-safe helpers for marking items for deconstruction and managing item lists. Updates all usages of Item.ItemList and DeconstructItems to use new APIs, improving performance and safety in multi-threaded contexts. Also refactors MeleeWeapon and Projectile impact queues to use ConcurrentQueue, and updates related logic throughout the codebase.
