Eventloadactor
The eventloadactor blocks run when an actor is loaded into the map -- despite the name, it is not a game event but rather an entirely separate type of block ended with enda. It is most often used for moving settings out of a sprite's hitag or lotag and into a gamevar before they have undesirable hardcoded effects.
