So i am making an enemy that goes towards player's initial direction but player can move away from that direction

float speed = 3f;//speed of object
GameObject player; //Reference of player
// float waitTime;//Time to wait
// public float startWaitTime;
Vector2 playerPos;//To know position of player

private void Start()
    player = GameObject.FindWithTag("Player");
    playerPos = new Vector2(player.transform.position.x,player.transform.position.y);
    Debug.Log("Took pose");

private void FixedUpdate()
    transform.Translate(playerPos * speed * Time.deltaTime);
    Debug.Log("Moving towaeds player");

it doesnt go anywhere
