Decisions can be modded into the game. They are optional actions that count rulers or above may take.

Location[edit | edit source]

Decisions belong in .txt files in the mod's common\decisions folder. Each text file may contain multiple decisions.

Structure[edit | edit source]

Decisions may be defined like so:

my_decision = {

	# Put keys, etc. here


Keys/blocks[edit | edit source]

The table below shows keys and blocks that may be defined. "Boolean" values may be either yes or no.

Key/block Type Description Example
picture String (file name) Sets the image of the decision.
picture = ""
major Boolean
ai_goal Boolean
ai_check_interval Integer How many months to go between each check of this decision. Has to be set, except if ai_goal = yes is set. An interval of 0 means the AI will never check this decision
is_shown This determines the conditions required for the decision to appear in the decisions tab.
is_valid_showing_failures_only Is the interaction valid to be selected in it's current setup, trigger only displays failures
cost Block Sets the cost of the decision in terms of gold, piety and prestige. The default value for each resource is zero. Not every resource has to be defined.
cost = {
	gold = 42
	piety = 42
	prestige = 42
ai_potential The willingness for the AI to take the decision. ai_potential = {

always = yes


ai_will_do Guarantees the AI will take the decision. ai_will_do = {

base = 1000



Basic example[edit | edit source]

custom_decision = {
	picture = ""
	desc = custom_decision_desc
	selection_tooltip = custom_decision_tooltip

	is_shown = {

		# Put conditions for the decision to show up here.


	effect = {

		# Add effects of the decision here.


	ai_check_interval = 0 # Change this value if you want the AI to consider this decision.

Decision ID[edit | edit source]

Each decision uses an internal ID for reference within the game's files. The internal name of a decision in the game's files can be found by following these steps:

  • Take the decision's name.
  • Turn all letters into lowercase (A...Z->a...z).
  • Replace spaces ( ) with underscores (_).
  • Add _decision to the end.

Decisions with in-game names that do not match their internal name are included in the table below:
