Correctly changing the angle of a monster?

[Ghost_Fang]

I have a monster sending out a traceline, and when the traceline is interupted by a wall i want the monster to face the wall at the correct angle. ive tried many combinations of vectoangles and trace_plane_normal. Is their something i didn't do right?


traceline (self.origin + '0 0 20', self.origin + '0 0 20' + v_forward*50, TRUE, self);
if(vlen(self.origin + '0 0 20' - trace_endpos) < 30)
{
self.angles_y = vectoangles(trace_plane_normal);
}

mankrip: maybe I should have been more explicit, but I didn't mean to read exhaustively. What you're doing is more or less how I got it: play a bit, read a bit, repeat. However, without a bit of reading, it's very difficult to understand just what information a dot product or cross product gives you. It's for that reason I recommend doing some reading.
