Modding historical events

[Prinz Wilhelm]

Hi y'all! I'm modding the historical events of HoI2 (Marco Polo bridge incident, pearl harbor) and I am wondering, will this make the event fire on the specified date?

#########################################################################
#  Marco Polo Bridge Incident (Japan, China)
#########################################################################

event = {
	id = 20
	random = no
	country = JAP

	# Historical event July 1937
        # http://ibiblio.org/pha/monos/144/144chap2.html

	name = EVT_20_NAME
	desc = EVT_20_DESC
	style = 0
	picture = "Marco_Polo"

	trigger = {
            exists = CHI
		NOT = {
			war = { country = JAP country = CHI }
			puppet = { country = JAP country = CHI }
			war = { country = JAP country = CSX }
			puppet = { country = JAP country = CSX }
			war = { country = JAP country = CGX }
			puppet = { country = JAP country = CGX }
			alliance = { country = JAP country = CHI }
			alliance = { country = JAP country = CSX }
			alliance = { country = JAP country = CGX }
			alliance = { country = CHI country = SOV }
			alliance = { country = CHI country = USA }
			alliance = { country = CHI country = ENG }
			control = { province = 1205 data = JAP } 
			war = { country = JAP country = SOV }
		}
	}

        date = { day = 7 month = july year = 1937 }

	action_a = {
		name = EVT_20_ACTA
		ai_chance = 100
		command = { type = war which = CHI }
		command = { type = war which = CSX }
		command = { type = war which = CGX }
		command = { type = belligerence which = JAP value = -50 } #The DoWs above is for free
		command = { type = relation which = USA value = -10 }
		command = { type = relation which = ENG value = -10 }
		command = { type = relation which = SOV value = -10 }
		command = { type = relation which = CHI value = -50 }
		command = { type = relation which = CSX value = -50 }
		command = { type = relation which = CGX value = -50 }
		command = { type = dissent value = -10 }
		command = { type = domestic which = interventionism value = 1 }
		command = { type = domestic which = defense_lobby value = 2 }
		command = { type = manpowerpool value = 50 }
		command = { type = trigger which = 21 }

	}
	action_b = {
		ai_chance = 0
		name = EVT_20_ACTB
		command = { type = dissent value = 3 }
		command = { type = belligerence which = JAP value = -50 } #Peace, Love and Understanding
		command = { type = domestic which = interventionism value = -1 }
		command = { type = domestic which = defense_lobby value = -1 }
	}
}

Please help a noob at event making.

Anyone?

Hey!

Hiya, there. Just for your information: The problem with events, as I've been told, is that sometimes the engine doesn't load them up right on the first day they're supposed to go off. That's why most historical events have a period of some fifteen to thirty days when they can be activated, even if they only happened on one, specific day.

So, you might wanna put a 'deathdate' in there for a month later, but beyond that, your event looks pretty solid, to me. You also might wanna plug in an offset - such as 3, say:

        date = { day = 7 month = july year = 1937 }
        offset = 3
	deathdate = { day = 7 month = august year = 1937 }

Of course, I'm relatively inexperienced with modifying dates and offsets, but beyond that, it looks like you've got things well in hand.
I might've missed something - anyone else wanna give this a shot?

In Victoria, to make an event happen on a specific date, remove offset and deathdate. If the triggers aren't met on that specific date, the event never happens.

Looks good, but day should be 6, so that event triggers on the 7th not on the 8th.

Thank you, forgot about that one. Always comes and haunt you.
