The setFactionAttackableAbove native AI script function sets the group as being attackable or not by players having their fame matching the specified condition.

()setFactionAttackableAbove(Faction: s, Threshold: f, Attackable: f) // setFactionAttackableAbove_sff_ 

• Faction (string): The faction against which player fame will be tested.
• Threshold (float): The test threshold above which players will be able to attack.
• Attackable (float): Tells whether the group is attackable or not (0 meaning not attackable, 1 meaning attackable).

()setFactionAttackableAbove("TribeNightTurners", 0, 1);

This example code sets the group as attackable by players with positive "TribeNightTurners" fame.
