How could I convert the y axis in a Vector 3 into a float?

[Chickenator]

Here’s my script :

#pragma strict

var forwardSpeed : float = 20;
var leftRotate : float = 5;
var rightRotate : float = 5;
var upLift : Vector3;
var number : float = 0;

function Update () {

upLift = transform.InverseTransformDirection(rigidbody.velocity);
  
if (Input.GetKey(KeyCode.Space)) {

	rigidbody.AddForce (transform.forward * forwardSpeed);

}


}

So I want the y axis of upLift to be turned into a float and used in the variable “number”

[jgodfrey]

number = upLift.y;
