Vector2.Dot
static function Dot(lhs: Vector2, rhs: Vector2): float;
static float Dot(Vector2 lhs, Vector2 rhs);
static def Dot(lhs as Vector2, rhs as Vector2) as float
Description

Dot Product of two vectors.

Returns lhs . rhs.

For normalized vectors Dot returns 1 if they point in exactly the same direction; -1 if they point in completely opposite directions; and a number in between for other cases (e.g. Dot returns zero if vectors are perpendicular).

For vectors of arbitrary length the Dot return values are similar: they get larger when the angle between vectors decreases.
