Unity provides some commonly used static variables in the Scripting Reference (Figure
2-33
).

Vector2 static variables described in the Unity Scripting Reference
Replace
myVector
with
Vector2.up
in the
Debug.Log
statement to confirm that you get (0, 1) as the
output in the Console. If you are wondering why there isn't a
.down
or
.left
, you just use
-.up
and
-.right
for their opposites.
The length of a vector is called its
magnitude
. You may or may not remember using the Pythagorean
Theorem in geometry class to find the distance between two points, but Unity steps in here for you
with
Vector2.magnitude
when you need to determine the distance between game objects. Click on
“magnitude” to take a quick look at the description of
Vector2.magnitude
(Figure
2-34
).
