This page is about modding Agendas.

They are defined at "common/agendas/xxx.txt".

Data Structure[]

weight_modifier - Modifies how likely should a leader have this Agenda.
modifier - A block of Modifiers to be applied to the Empire for as long as this leader remain on the ruler's seat.

Whenever a leader becomes the ruler or a candidate of an Empire with an Authority that has has_agenda = yes, if the leader doesn't have an Agenda, a random Agenda is chosen for the leader and they will preserve the Agenda for their lifetime and will never change to another.

Unlike Mandates, the Agendas don't have some sort of on_term_started. All an Agenda can be relevant to the game is its Modifiers.

There are neither Conditions to check the Agenda nor Effects to change the Agenda.

(However, it is still possible for modders to nearly ensure that a desired custom agenda is selected, as shown in the second example below.)

Example of Default Agenda[]

Science Leap[]

agenda_science = {
	weight_modifier = {
		weight = 100
		modifier = {
			factor = 1.5
				from = {
					has_ethic = ethic_materialist
				}
			}
		modifier = {
			factor = 2
				from = {
					has_ethic = ethic_fanatic_materialist
				}
			}
		modifier = {
			factor = 1.5
			leader_class = scientist
		}
	}
	
	modifier = {
		all_technology_research_speed = 0.10
	}
}

Example of Modded, Near-Guaranteed Agenda[]

Modded Agenda[]

agenda_modded_agenda = {
	weight_modifier = {
		weight = 100000000      #Such a high weight means this agenda will almost certainly be selected, unless ruled out by the modifier below.
		modifier = {
			factor = 0.0        #This modifier section will reduce the chance of getting this agenda to zero.
			from = {
				NOT = {
    					has_civic = civic_custom_civic     #Thus, any empire that does not have this civic has zero chance of getting this agenda, while any empire with this civic probably will.
				}
			}
		}
	}

	modifier = {
		all_technology_research_speed = 0.05
		pop_happiness = 0.05
		species_leader_exp_gain = 0.10
	}
}

In this latter example, each new leader (including the leader at game start) is very likely to be assigned this agenda, for as long as the empire retains the key custom civic.
