@Future Pilot: As far as i know:
1. FINISH_BEACON is called from any and every exit beacon event. If i recall correctly it's an eventList that contains some generic events. I haven't found a way to set up a specific event for the exit beacon of a sector.
2. I doubt it. The only way to jump to a sector with events is by using the <secretSector/> element. It jumps you to a sector called "CRYSTAL_HOME". It doesn't count as an additional sector, instead its exit advances you to the next one.
Basically: if you're in sector 1 and jump to the crystal sector, when you reach its exit you'll be transported to any of the available sector 2's.
The first sector in a game will be the one defined in the STANDARD_SPACE sectorDescription tag found in sector_data.xml.
This sector is also used whenever the game tries to load a missing or faulty sector. You can modify the first sector by STANDARD_SPACE to your liking, but the name of the first sector of a game will always be "Civilian sector". It seems to be hardcoded.
3. I dunno. ¯\_( ·_· )_/¯
maybe... just maybe... you could define a sector 2, though.
I mean, if you do this:
- rename the original FINISH_BEACON eventList to else, let's say OLD_FINISH
- make a new empty eventList called FINISH_BEACON
- put this child element in it: <event load="OLD_FINISH"/>
- now make the exit event that you want and give it a name, let's say "HOLY_BALLS"
- put this attribute in your event: unique="true"
- put like 20 of these child elements in the FINISH_BEACON list: <event load="HOLY_BALLS"/>
What should happen is that the game draws HOLY_BALLS first, then it doesn't draw it anymore because it's unique! Since all the options but one lead to HOLY_BALLS, the game will only be able to draw from that one, and in this case it's the old eventlist. This cannot not work!!!
I've once tried to do this same thing even with one HOLY_BALLS and one OLD_FINISH, and
the game seemed to always draw the unique option first..! (translation: i'm a stupid primate that can't understand chaos theory. OOHK OOK OOOHHK!!)
But yeah, the point is: if HOLY_BALLS sends you to CRYSTAL_HOME, and you set up STANDARD_SPACE, you can basically define what sector 1 and 2 will be! ...prob'ly!
This will remove the crystal sector though, so you should probably remove some vanilla events or something. >_>
