1st. Ok I am trying to set up this script made by blizzard and I was wondering how do I go about making it so when you select the skill option from the menu it takes you to the skill learning menu aka Scene. I know to call it you use $scene = Scene_SkillChange.new but where do I place it so it displays that and not the regular skill menu.
2nd. Is there a way to make the skills you set for this system have requirements? What I am trying to say is, is it possible to make it so in order to learn certain skills you have to have learned some prerequisit skills?
