How to create an event that would fire just once?

[nachinus]

I've just started to fiddle with the EUR/EU3 code and being used to the old HoI/EU2 one, I'm a bit lost with how the new event system works. I'm wondering how to make an event that will only fire only once in the whole game, and once it fires no other country can get it.

I know how to make an event fire only once for a given country, using flags (in fact I would also like to know if there's any other way than this one, I don't like filling the world with country_flags), but I have no idea if there is in the new EU3/EUR engine any kind of event that fires only once, like old HoI or EU2 events, or any trigger or special modifier that can be added so that it is an unique event.

i would do this:
1. use the trigger "ai = no", so the event fires only for the player. with the switches you can modify the event in a way, that it is working for all countries/provinces/characters as you want.
2. use a country-flag for the players country, so its exclude that the event fires a second time. 1 country_flag should be ok.

Mmm, good thinking, mate. But sadly I'd like that the event could fire for the AI too.

hmm...my suggestion: the event should trigger a "flag" for the triggering nation what would not allow the same nation to trigger it again... of course this would make the event trigger once PER nation o

You could make the event trigger another event for all other countries which tells them that the unique event has taken place somewhere else. This secondary one would give those countries the flag which prevents the unique event from firing.

I'm sure there's a way to give every country a flag when an event fires, not just the receiving country, though.

but this would mean a LOT of flags...and a possibility on crashing

next thought:

shouldn´t a trigger like

NOT = {
   any_country = { has_country_flag = blabla }
}

prevent the event from fireing, if ONE flag to ONE country is given?

Can't you set a global flag?

Oh! That's a good one!. I hadn't think about it, thanks!
