Well, when I type "-1**2" into Python, it returns -1. If I run "1**2 +
-1**2" it returns 0. So, is there a bug in Python then? Running 2.6.6
on Ubuntu 10.10.
Removing the if statement from get_angle fixed the angle problem for
me, because of this.

Your mistake basically was that you assumed that -1 ** 2 == -1 which
is not.
Hi again
def get_angle(self):
if (self.get_length_sqrd() ==0):
return 0
return math.degrees(math.atan2(self.y,self.x))
Well the 0 length check is ok, since a 0 length vector does not really
have an angle. But I guess you see it now.
