Base Scenario Event
======================

.. code-block:: csharp

  public abstract class BaseScenarioEvent : IScenarioElement

Base class for a condition which can trigger a scenario. Add your own by deriving from it - new subclasses automatically appear in the Scenario Editor's **Events** dropdown.

Built-in event types:

================================  ==============
Event                             Description
================================  ==============
**MatchStartedEvent**              Fires once, when the match starts. No parameters.
**UnitSelectedEvent**               Fires when a unit owned by a specific player (``PlayerId`` + ``CompareMode``) is selected.
**UnitDiedEvent**                   Fires when a unit matching a configured ``UnitTarget`` dies.
**TriggerZoneEvent**                Fires when a unit enters or exits a :doc:`trigger_zone` (``Type``, a ``ZoneTriggerType`` of ``Enter``/``Exit``). Reacts to every Trigger Zone in the scene - there is no per-zone filtering yet.
================================  ==============

Hooking up a custom event subclass to a real game event still requires a small code change of your own - see ``ScenariosSystem.MakeBuiltInSubscriptions`` for how the built-in ones are wired up.
