Changing how random an event actually is?

[tuore]

If I make a random event, can I change how random it will be? If I'd like it to have a 50% chance of firing?

Or, if nothing else, can I make ONE events that fires for EVERY nation during one week?

Or, if nothing else, can I make ONE events that fires for EVERY nation during one week?

That's certainly possible. Here are some events that I made for all revolters so I can actually see them once in awhile...

event = { 
	id = 12000119
	trigger = { 
	NOT = { exists = ALG }
	NOT = { local_flag = ALGInd }
        ai = yes
        control = { province = 949 data = -1 }
		NOT = {
			country = FRA
			country = ITA
			country = VIC
			country = ENG
			country = ub2
			country = ARA
		}			
	}
	random = no
        persistent = yes
	name = "AI_EVENT"
	desc = "AI_EVENT"
       picture = "Uprising"
	style = 0

	date = { day = 1 month = january year = 1936 }
	offset = 14
	deathdate = { day = 29 month = december year = 1999 }
	
	action_a = { 
		ai_chance = 85
		name = "Keep these lands" 
		command = { type = local_setflag which = ALGIND }
		command = { type = dissent value = 5 }
		command = { type = belligerence value = 10 }
	}
	action_b = { 
		ai_chance = 3
		name = "Make Independent" 
		command = { type = independence which = ALG value = 0 }
		command = { type = belligerence value = -5 }
		command = { type = set_relation which = ALG value = 180 }
		command = { type = vp value = 10 }
	}
	action_c = { 
		ai_chance = 12
		name = "Make Puppet" 
		command = { type = independence which = ALG }
		command = { type = dissent value = 2 }
		command = { type = alliance which = ALG }
		command = { type = make_puppet which = ALG }
		command = { type = set_relation which = ALG value = 200 }
	}
}

It fires for any ai country ( except the ones excluded ) that controls Algiers. Just leave out the "country = " line, set your trigger conditions and your event will fire for every country that meets those trigger conditions.
