aiGuard chapter 7

Hey, I use to have a problem with aiguard (use Advanced 3D GP All in One by Kenneth C. Finney)the guard just turning, and not shooting, and aiguard dont loose health. i look up here and found the answer to get my aiGuards working (about their being typos in the cd and book, and me have to add player.cs to aiguard.cs and changing some of the coding to make sure the guards loose health when shot at). The problem is my teacher want me to tell what i had to do to change to get them to work (i forget what i did), when i came back to try to find thread or forums. i couldent find it.

can someone tell me which thread it was called.
