Divide each component by the vector's magnitude:

You don't want to do it as separate Functions., as it slows the code down (see: Array Performance Thread)
But yeah...

Type Vector
X As Float
Y As Float
Z As Float
EndTyp

Function VectorNormalise( Vec Ref As Vector )
Local Length As Float
Length = Sqrt( Vec.x * Vec.x + Vec.y * Vec.y + Vec.z * Vec.z )
Vec.x = Vex.x / Length
Vec.y = Vec.y / Length
Vec.z = Vec.z / Length
EndFunction

Weirdly GetVector3Normalize( ) isn't one of the Math Functions., mind it seems like an after thought Command Library anyway.
