2d walking script not working

import UnityEngine;

public var walkSpeed : float = 15f;

function Update () {

if(Input.GetKey(KeyCode.D))
{	
transform.Translate(new Vector3(walkSpeed, 0, 0) * Time.deltaTime);
}


if(Input.GetKey(KeyCode.A))
{	
transform.Translate(new Vector3(-walkSpeed, 0, 0) * Time.deltaTime);
}

}

transform.position not transform.Position

Capitalization is important.

Try transform.Translate instead of transform.Position

Your script has many errors. I highly recommend you being by following some tutorials: Learn Game Development Without Coding Experience | Unity

At a glance:

  • input needs to be Input
  • Position needs to be position
  • new Vector2.forward(Vector2.forward * walkSpeed * Time.deltaTime) should be just Vector2.forward * walkSpeed * Time.deltaTime
  • The whole lot should be inside Update(), not Start()

I think you need to set it equal to the new position:

transform.position = new Vector2(Vector2.forward * walkSpeed * Time.deltaTime);
