The angles might be straddling 0 and 360. Try adding
Code:

---

temp.pan = ang(temp.pan);  // EDIT: I put x instead of pan... shouldn't matter though :P
temp.tilt = ang(temp.tilt);

---

right after you scale temp. This changes it so the angles are -180 to 180, so he'll turn in the right direction.

Thanks a lot, this code works fine!
