[XP] Friendship System

I would like a short system where I can call on a script to add an amount of friendship linked between the characters. Also, I would like it if someone made it so that when a character uses an item on another ally, the friendship between them grows. I would use this system for a short aftermath of the game between the characters, and call on different special events in it. I would like the max friendship to be 1000, and I want decreased friendship to be available the same way as to add it.

I would be very happy if someone made this for me. Credit will obviously be given. I don't have a deadline, so you can relax on it.

Thanks.

Just FYI, you can do this through a simple event system, if you wanted to keep it simple of course.   I have a similar system right now in my own game, that keeps track of your fane points, and good/evil points..

But I forgot to mention an extra option in the menu that let's you connect to different allies to see how friendly they are, kinda like the Affinity chart in Xenoblade. Would that work as well?

As far as I am aware, there is no way to make an event change your menu options like that..
