Rigidbody2d Moving up and Down but not left and right

Questions & Answers

Hello guys,

Fresh unity user here,

My RigidBody2D (pong game) is correctly moving up and down, but not left and right. The code seems simple, but i can’t understand why it’s not moving.

I have set the controls to the correct KeyCode.

Can you explain what mistake i have made?

There is my code :

var moveUp : KeyCode; 
var moveDown : KeyCode;
var moveLeft : KeyCode;
var moveRight : KeyCode;

var speed : float = 12;

function Update () {

	if (Input.GetKey(moveUp))
	{
		GetComponent.<Rigidbody2D>().velocity.y = speed;
	}
	else if (Input.GetKey(moveDown))
	{
		GetComponent.<Rigidbody2D>().velocity.y = -speed;
	}
	else if (Input.GetKey(moveLeft))
	{
		GetComponent.<Rigidbody2D>().velocity.x = -speed;
	}
	else if (Input.GetKey(moveRight))
	{
		GetComponent.<Rigidbody2D>().velocity.x = speed;
	}
	else
	{
		GetComponent.<Rigidbody2D>().velocity.y = 0;
	}

	GetComponent.<Rigidbody2D>().velocity.x = 0;

}

Thanks a lot.

You are resetting x velocity to 0 in line 31. So, you set speed correctly, but then you set it to 0 in the end.

Something like this would be better:

function Update ()
{
 
     GetComponent.<Rigidbody2D>().velocity.y = 0;
     GetComponent.<Rigidbody2D>().velocity.x = 0;

     if (Input.GetKey(moveUp))
         GetComponent.<Rigidbody2D>().velocity.y = speed;

     if (Input.GetKey(moveDown))
         GetComponent.<Rigidbody2D>().velocity.y = -speed;

     if (Input.GetKey(moveLeft))
         GetComponent.<Rigidbody2D>().velocity.x = -speed;

     if (Input.GetKey(moveRight))
         GetComponent.<Rigidbody2D>().velocity.x = speed;

 }
