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's 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's 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
