Class EventBus

Namespace

Core

Assembly

Core.dll

High-performance event bus for decoupled system communication Features: Type-safe events, zero-allocation processing, frame-coherent batching Performance: ZERO allocations during gameplay (no boxing), batch event processing

Architecture: Uses typed EventQueue{T} wrapper to avoid boxing and reflection See: Assets/Archon-Engine/Docs/Engine/data-flow-architecture.md

Methods

Clear()

Clear all events and listeners - useful for scene changes

public void Clear()

Dispose()

public void Dispose()

Emit<T>(T)

Emit an event - queued for frame-coherent processing ZERO ALLOCATION: Event stays as struct T in EventQueue{T}

public void Emit<T>(T gameEvent) where T : struct, IGameEvent

Parameters

gameEvent T

Type Parameters

T

LogDebugInfo()

Debug information for editor

public void LogDebugInfo()

ProcessEvents()

Process all queued events - call once per frame Frame-coherent processing ensures consistent event ordering ZERO ALLOCATION: No boxing, events stay as struct T throughout

public void ProcessEvents()

IDisposable

Type Parameters

T

Unsubscribe<T>(Action<T>)
