How to assign Rigidbody2d to a player using Javascript

Questions & Answers
1

I am trying to connect Rigidbody2d to a cube named Player so that it is able to jump. This is my code so far…
#pragma strict

function Start () {

}

function Update () {
if (Input.GetKeyDown(KeyCode.Space)); {
GetComponent(Rigidbody2D).velocity = new Vector2(0,10);
}
}
When I try to play my game this comes up…

MissingComponentException: There is no ‘Rigidbody2D’ attached to the “Player” game object, but a script is trying to access it.
What do I do to fix this. I am using Javascript.

Either add a Rigidbody2D component to the cube in the Editor, or put this in the script:

function Start()
{
    AddComponent(Rigidbody2D);
}
