Replaced direct access to GameMain.Server.ConnectedClients with array snapshots in multiple server-side classes to prevent concurrent modification issues during parallel updates. Also updated PhysicsBody and LevelTrigger to avoid static/shared state in parallel contexts, improving thread safety and reliability.
Refactors event, entity, and physics management to use thread-safe and lock-free data structures (Immutable collections, ConcurrentQueue, ConcurrentDictionary, Channel) for improved concurrency and performance. Replaces O(n) queue lookups with O(1) set/dictionary checks, ensures atomic updates for shared state, and optimizes queue draining and deferred action processing. Updates related code to use new APIs and patterns, and adds documentation for thread safety and workflow.
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.
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.
