Detailed Description

[AI] Represents an event media action (a discrete event) parsed from script/scene data (SI files).

[AI] This class extends MxDSMediaAction to provide event functionality (used for signaling or discrete scriptable events) in the LEGO Island engine's data-driven object system. The event action can be cloned and supports polymorphic type identification.
