Listening

ECS events are handled by EntityEventSystem subclasses, not by getEventRegistry().register().

public class MyPrefabEntityHandler extends EntityEventSystem<EntityStore, PrefabPlaceEntityEvent> {
    @Override
    public Query<EntityStore> getQuery() {
        return MY_COMPONENT_TYPE;
    }

    @Override
    public void handle(int index, ArchetypeChunk<EntityStore> chunk,
                       Store<EntityStore> store, CommandBuffer<EntityStore> commandBuffer,
                       PrefabPlaceEntityEvent event) {
        int prefabId = event.getPrefabId();
        Holder<EntityStore> holder = event.getHolder();

        // Example: track entities spawned by prefabs
        trackPrefabEntity(prefabId, holder);
    }
}

// Register in plugin setup():
getEntityStoreRegistry().registerSystem(new MyPrefabEntityHandler());
