Inifinite Runner Testing Phase

I started to learn how to code in Unity and was able to control the player with the A and D keys going left and right as it goes down the track.

This is the code that I typed in Microsoft Visual Studio

public class PlayerMovement2 : MonoBehaviour {

public Rigidbody playerRB;

public int speed;

// Use this for initialization

void Start() {

}

// Update is called once per frame

void FixedUpdate() {

float newSpeed = speed * Time.deltaTime;

playerRB.AddForce(0, 0, newSpeed);

if(Input.GetKey("d"))

{

playerRB.AddForce(20, 0, 0);

}

if(Input.GetKey("a"))

{

playerRB.AddForce(-20, 0, 0);

}

}

}
