Random event

I want to make an event which can occur, but not necessarily. Let's say I want it to occur in 60% of the games. How to code that?

I want to make an event which can occur, but not necessarily. Let's say I want it to occur in 60% of the games. How to code that?

My suggestion involves 2 events, assumes that there is a specific country this event should occur for, and is completely untested:

event = {
	id = 100001 # change this 
	random = no
	country = HOL # change this too, probably.

	trigger = { 
		random = 60 # the 60% chance...
                NOT = { event = 100001 } # if we haven't fired
                NOT = { event = 100002 } # if the never fire side hasn't fired
	}

	name = "Hey, 60% hit!" 
	desc = "This event should only occur in 60% of the games!"

	date = { day = 1 month = january year = 1936 }
	offset = 30
	deathdate = { day = 30 month = december year = 1947 }

	action_a = {
		command = { type = delete_unit which = -1 } # or whatever
	}
}

event = {
	id = 100002 # change this 
	random = no
	country = HOL # change this too, probably.

	trigger = { 
		random = 40 # the 40% chance...
                NOT = { event = 100001 } # if the main event hasn't fired
                NOT = { event = 100002 } # if we haven't fired
	}

	name = "Hey, 40% hit!" 
	desc = "This event should only occur in 40% of the games!"

	date = { day = 1 month = january year = 1936 }
	offset = 30
	deathdate = { day = 30 month = december year = 1947 }

	action_a = {
		command = { type = delete_unit which = -1 } # or whatever
	}
}

Basically, as soon as the game starts 2 events start being tested each month, one with a 60% chance and one with a 40% chance. As soon as one of them fires, the other will never fire.

Main drawback is that an event will fire to symbolize that the other will never happen, which is somewhat annoying.

If this event can fire once, for whichever country hits it first, I would replace "country =" with "invention = yes", remove the date / offset / deathdate, and add a global flag instead of testing on the events.

If this event can fire once per country for all countries, I would replace "country =" with "invention = yes", remove the date / offset / deathdate, and add a local flag instead of testing on the events.

trigger = {
random = 60
}

date = { day = 2 month = january year = 1936 }


60% chance on Jan 3rd (or any other fix date)

Thanks, I supposed that "random = x" is the key, but I have seen some events with random = 40 and they occured almost every time.
Perhaps it was just a coincidence.

No, some events are checked more than once, then the X is not the real percentage.

trigger = {
random = 60
}

date = { day = 2 month = january year = 1936 }


60% chance on Jan 3rd (or any other fix date)

This event will either fire on 1936-1-3, or never...

With the date / offset / deathdate parameters, the events get multiple chances to hit the random number.

If you make

name = "AI_EVENT"

Then the message should only appear to the player who gets the event. If you're any other country, then it should just take place without letting you know.
