Scripted trigger

is_house_head

is_house_head = yes

game/common/scripted_triggers/00_dynasty_triggers.txt, line 3 (11 lines). No parameters.

is_house_head is a scripted trigger in Crusader Kings III, written at line 3 of its file. It takes no parameters: is_house_head = yes (or no). The game's script calls it in 194 places, among them Command Family to Attend Examinations (decision), Commission Artifact (decision) and Consult Heaven (decision). Patch 1.20.1.2, from game/common/scripted_triggers/00_dynasty_triggers.txt.

What it checks

  • If

    a check the game hides

    Then

    • Their house:
      • house_head = scope:house_check

• the game's own tooltip text · ◦ our reading of the script line · code the script where neither exists

“They” is whatever it runs on (the scope it is called in). The scripted triggers and effects it calls link to their own pages; $PARAMETERS$ stay as written: each call fills them in.

The script as written (11 lines of game script)

		limit = {
			exists = this
		}
		save_temporary_scope_as = house_check
		house ?= {
			house_head = scope:house_check
		}
	}
}
