EventBus API

This page summarizes the public EventBus surface area as used by Event Monitor. Names and signatures follow the Unity package; always verify in your installed version.

Namespace: EventMonitor.Runtime

Runtime settings

Member	Purpose
`IsRecording`	When `false`, new records are not appended.
`EnablePayloadCapture`	When `true`, payload capture paths are active (toolbar + `TagPayload`).
`CaptureStackTraces`	When `true`, new records may include stack traces (higher overhead).
`CaptureInvokeTiming`	When `true`, IL-injected Begin/End timing records `DurationMs` on INVOKE rows and emits Profiler markers.

Editor session persistence of these flags is handled by Editor-only settings code.

Manual recording (advanced)

These are safe to call from custom tooling or tests. Game code usually relies on ILPP instead.

Method	Use
`RecordSubscribe(eventName, ownerType, ownerInstanceId, subscriberType, subscriberMethod)`	Append a SUB row and update live state.
`RecordUnsubscribe(...)`	Append an UNSUB row and update live state.
`RecordInvoke(eventName, ownerType, ownerInstanceId, subscriberCount, parameters, parameterNames)`	Append an INVOKE row with optional parallel parameter names.

Payload tagging

Method	Use
`TagPayload(params object[] args)`	Attach argument values to the next invocation on this thread when payload capture is enabled. Names use UI fallbacks unless set via `TagPayloadWithNames`.
`TagPayloadWithNames(string[] names, object[] args)`	Attach named payload to the next invocation (used by ILPP; available for custom dispatch).

Injected entry points (do not call from gameplay)

ILPP injects calls to static helpers such as:

RecordSubscribeDelegate(string eventName, string ownerType, int instanceId, Delegate handler)
RecordUnsubscribeDelegate(...)
RecordInvokeDelegate(string eventName, string ownerType, int instanceId)
BeginInvokeTiming(string eventName) / EndInvokeTiming(string eventName) — bracket instrumented Invoke() for duration capture.

They are not intended for manual use; they exist so rewritten IL can report activity with stable signatures.

Warning: Relying on injected methods from hand-written code is fragile and may break across package updates.

UI integration

Member	Purpose
`OnRecordAdded`	Raised when a record is appended (Editor window repaints).

Stats and queries

The package exposes counters and ring-buffer stats (for example total records, invoke counts) for the Stats tab and toolbar. Exact property names may vary by version — inspect EventBus in your IDE.

Leak detection

Member	Purpose
`EventMonitorLeakDetector.DetectedLeaks`	Read-only list of detected subscription leaks.
`EventMonitorLeakDetector.LeakCount`	Number of unique detected leaks.
`EventMonitorLeakDetector.ScanNow()`	Force a leak scan (tests / manual refresh).

Exception breadcrumbs

Member	Purpose
`EventMonitorExceptionBreadcrumbs.GetBreadcrumbs()`	Read captured Play Mode exceptions with preceding timeline records.
`EventMonitorExceptionBreadcrumbs.BreadcrumbCount`	Number of stored exception entries.

Subscriber growth alerts

Member	Purpose
`EventMonitorSubscriberGrowthMonitor.RecentWarnings`	Read recent growth warnings.
`EventMonitorSubscriberGrowthMonitor.WarningCount`	Number of warnings in the recent list.
`EventMonitorSubscriberGrowthMonitor.Threshold` / `MinGrowthStreak`	Runtime thresholds (Editor UI persists via EditorPrefs).
