Listening

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

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

    @Override
    public void handle(int index, ArchetypeChunk<EntityStore> chunk,
                       Store<EntityStore> store, CommandBuffer<EntityStore> commandBuffer,
                       MoonPhaseChangeEvent event) {
        int phase = event.getNewMoonPhase();

        // Example: trigger special behavior on full moon
        if (phase == FULL_MOON) {
            triggerFullMoonEvent();
        }
    }
}

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