Dot(Vector2, Vector2)

Calculates the dot product of two vectors.
public static float Dot(Vector2 lhs, Vector2 rhs)

Parameters

lhs

Vector2
The first vector.

rhs

Vector2
The second vector.

Returns

Type

Description

floatThe dot product of 
lhs
and 
rhs
.

Remarks

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.
