EVENT SPAWN
EVENT_SPAWN is a Game Event.
This event is triggered when the attributes of actor are defined by the game. It applies to most sprite that appear on the map (projectiles excluded), this is, both due to the spawn (similar to EVENT_EGS) command on whenever the actor was already part of the map (similar to EVENT_LOADACTOR but later in the process). This is useful to modify an enemy as it works for both cases.
Chronologically, this event is triggered after EVENT_EGS or eventloadactor.
