EventBus Pro - Thread Safe Events

Stop Writing Spaghetti. Start Building Systems. Every growing Unity project hits the same wall: components calling each other directly, fragile references breaking on prefab changes, and event spaghetti that is impossible to debug. Unity EventBus solves this with a clean, production-ready event-driven architecture that keeps your systems completely decoupled and your codebase maintainable at any scale. Why Developers Choose Unity EventBus Zero Allocation on the Hot Path Events are structs dispatched through a pre-built snapshot array. No boxing, no per-frame heap allocations, no GC spikes even under thousands of events per second (see the StressTest sample). Type-Safe by Design Strongly-typed events via the IEvent interface catch mismatches at compile time, not at runtime. Thread-Safe Out of the Box Publish from background threads, Jobs, or async tasks using PublishFromThread or the EventQueue system. Events are buffered and safely dispatched to the main thread every frame, no manual marshalling required. Async/Await Support Wait for a specific event without coroutines or polling. Full cancellation token support keeps async flows clean and leak-free. Automatic Memory Safety Owner-tracked subscriptions are automatically cleaned up when a MonoBehaviour is garbage-collected. Live Editor Debugger The built-in Event Bus Debugger window shows every registered event type, live subscriber counts, and a rolling publish log all in real time. Debug event flow without adding a single line of instrumentation code. Event Filtering Subscribe with a predicate to receive only the events that matter to a specific system. Filter by player ID, team, damage type, or any field on the event. What is Included The package ships with a complete runtime system covering the core bus, thread-safe event queues, owner-tracked bindings, and automatic lifecycle management. Editor tools include a live debug window and editor bridge for custom workflows. Four sample scenes with full source code cover every major use case: Basic - publisher/subscriber fundamentals, ideal starting point Arena - full gameplay demo with decoupled player, drone, and HUD systems StressTest - high-frequency performance validation under heavy event load Threaded - safe event dispatch from background threads Built for Professionals Full C# sourcecode. Assembly definitions keep compile times fast and project structure clean. Compatible with Unity 2021.3 LTS through Unity 6. No external dependencies.
