Replacing this code with a more C++ friendly version would require
drastic changes everywhere in the engine, and be more of a pain than a
benefit. I haven't yet done much vector math in HL2, but I do believe
that the Vector class has C++ style functions for this?
Half-Life 1's vector.h has this in CVector:
inline Vector Normalize(void) const
{
float flLen = Length();
if (flLen == 0) return Vector(0,0,1); // ????
flLen = 1 / flLen;
return Vector(x * flLen, y * flLen, z * flLen);
}
Half-Life 2 has no equivalent. However whereas in HL1, vector.h was not
shared with the engine, in HL2 it is, so this functionality cannot
simply be added in. The closest thing in functionality is called
NormalizeInPlace() which just called VectorNormalize() internally and
works the exact same way. This doesn't satisfy my desire to have a
Normalize() that returns a Vector as Normalize() of Half-Life 1 did.
The only way I can think of I would be able to have this is if I created
a subclass of Vector just for Normalize(). Ick!
