I spent a lot of time teaching myself c# script in order to adjust the character behaviors to my liking for my final project. In my scene, one of my characters approach you, then proceed to follow right behind you as you walk through the scene. Although I had no idea how to do this at first, I knew that I wanted to animate this in order to achieve a realistic effect. I looked up tutorials to write c# scripts for an "AI Enemy Follow" effect. It took a lot of time, but I was really happy when I finally got it (never had I imagined that I would be excited that a creepy man is following me). After this, I was then more comfortable with editing scripts and adjusting variables to achieve the full effect of my scene. I watched the videos I'd linked below, as well as reading Unity forums and tutorials.
