ProjectEditorCore

Shared editor abstractions for decoupled plugin communication.

Purpose

Provides delegates and interfaces that editor plugins can use without depending on each other directly. This follows the Dependency Inversion Principle (DIP) from SOLID.

Delegates

FDefinitionEvents::OnDefinitionRegenerated()

Broadcast when a definition asset (UObjectDefinition or other definition assets) is regenerated from JSON.

#include "DefinitionEvents.h"

// Subscribe (in ProjectPlacementEditor)
FDefinitionEvents::OnDefinitionRegenerated().AddUObject(
    this, &UDefinitionActorSyncSubsystem::OnDefinitionRegenerated);

// Broadcast (in ProjectDefinitionGenerator)
FDefinitionEvents::OnDefinitionRegenerated().Broadcast(TypeName, Asset);

Architecture:

ProjectEditorCore (this plugin)
+-- FDefinitionEvents::OnDefinitionRegenerated()
         ^                    ^
         |                    |
ProjectDefinitionGenerator    ProjectPlacementEditor
(broadcasts)                  (subscribes)

Dependencies

None - this is a leaf module that other editor plugins depend on.

Adding New Delegates

1. Declare delegate type in a new header (e.g., FOnSomethingHappened)
2. Add static accessor in a class (pattern from DefinitionEvents.h)
3. Document in this README
4. Add to plugin dependencies in consuming modules
