Debugging

Purpose

This section explains how to debug event flow and diagnose issues in Reactive SO. You will learn to use the built-in debugging tools and troubleshoot common problems.

Available tools

Reactive SO provides the following debugging tools.

Tool	Purpose
Event Monitor	Real-time event tracking with caller information
Action Monitor	Real-time tracking of action executions
Variable Monitor	Real-time variable state monitoring
Runtime Set Monitor	Real-time runtime set monitoring
Asset Browser	Browse, search, and manage all Reactive SO assets
RES Table View	View, edit, and save ReactiveEntitySet data in table format
Dependency Analyzer	Static analysis for scenes and prefabs
Manual Trigger	Test events and actions from Inspector without code
Subscribers List	View active subscribers during Play Mode

Question	Tool
Is my event firing?	Event Monitor (Monitor Window)
Did my action execute?	Action Monitor (Monitor Window)
What’s the current variable value?	Variable Monitor (Monitor Window)
What objects are in my runtime set?	Runtime Set Monitor (Monitor Window)
Who’s subscribed to this event?	Subscribers List
Where is this asset used?	Dependency Analyzer
Can I test without playing?	Manual Trigger
Which code raised this event?	Event Monitor (Monitor Window - Caller column)
Do I have memory leaks?	Subscribers List (scene transitions)
Are all assets assigned?	Dependency Analyzer
What value was passed with event?	Event Monitor (Monitor Window - Value column)

Common debugging scenarios

Event not firing

Problem Button click does not trigger expected behavior.

Steps

Open Event Monitor (Window > Reactive SO > Monitor)
Ensure “Show In Event Log” is enabled on the event channel
Click the button in your game
Check if the event appears in the log

Diagnosis

Event appears: Problem is in subscriber. Check Subscribers List.
Event does not appear: Problem is in publisher. Check event channel assignment and RaiseEvent() call.

Action not executing

Problem A quest reward or effect defined in an Action does not trigger.

Steps

Open Action Monitor (Window > Reactive SO > Monitor)
Ensure “Show In Monitor” is enabled on the action asset
Trigger the logic in your game
Check if the action execution appears in the log

Diagnosis

Action appears: Check the action’s C# implementation for logic errors.
Action does not appear: Check the code calling Execute() and verify the asset is assigned.

Event fires but nothing happens

Problem Event appears in Event Monitor but expected behavior does not occur.

Steps

Check #L column in Event Monitor (listener count)
If #L = 0, nobody subscribed
Select the event channel and check Subscribers List
Verify expected MonoBehaviours are listed

Diagnosis

Subscriber exists: Check subscriber method logic
Subscriber missing: Check OnEnable/OnDisable subscription code
Wrong subscriber: Check event channel assignment

Debug settings

Each asset has debug options in the Inspector.

Show In Monitor / Event Log

When enabled, activities appear in the Monitor Window during Play Mode.

Show In Console

When enabled, activities output to Unity Console. Use for traditional Debug.Log-style debugging.
