Do you know what the line "((goalVec.SafeNormalize()).SqDistance(goalVec) > 1.0f)" should mean?
I don't understand it's meaning neither why it calls Normalize() a second time, to me codewise it could also be done with goalDist only:
`dist(goalVec, normalize(goalVec))^2 = ((normalize(goalVec) . goalVec) - 1)^2 = (length(goalVec) - 1)^2 = (goalDist -1)^2`
