Decision modding

Decisions are national scripted effects which become visible under certain conditions and then available for selection when additional conditions are met.

Decision Script Layout

country_decisions = {
	decision name = {
		potential = {
			[triggers which determine the visibility of the decision]
		}
		highlight = {
			scope:province = {
				province_id = [province number]
			}
		}
		allow = {
			[triggers which allow the decision to be chosen]
		}
		effect = {
			[what the decision does upon selection]
		}
	}
}

Formable Country Example

Below is the script for forming Macedon. It becomes potentially available is a Macedonian culture nation has a capital in Macedonia or Greece and is not already Macedon or formable-Macedon. Then provinces are highlighted which, if owned, makes the decision available for selection. Selecting the decision then grants the effects of changing the country name, color, capital, and gives bonus effects.
