Error with code, cannot figure out solution...

Question

A few errors are popping up in unity when I tried to compose a simple movement script to move the player right and left. Can someone identify the problem and/or present me with an open solution?

Here is my code:

 using UnityEngine;
 using System.Collections;
 
 public class Movement : MonoBehaviour {
     
     public int speed = 5;
     
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
         if(gameObject.tag == "Player") {
             if(Input.GetKeyDown(KeyCode.A)) {
                 transform.Translate(Vector3(-1, 0, 0) * Time.deltaTime * speed);
             }
         }
 
         if(gameObject.tag == "Player") {
             if(Input.GetKeyDown(KeyCode.D)) {
                 transform.Translate(Vector3( 1, 0, 0) * Time.deltaTime * speed);
             }
         }
     }
 }

Thanks in advance!

When creating a new Vector3, you need the 'new' keyword in C# (not necessary in Javascript). Also you use GetKeyDown(). This will only fire for a single frame, so it only move once for each key press. If you want continuous movement, use GetKey() instead. And as @Loius indicated, the tag comparison is not necessary.

 using UnityEngine;
 using System.Collections;
  
 public class Bug16 : MonoBehaviour {
  
     public int speed = 5;
  
     // Use this for initialization
     void Start () {
  
     }
  
     // Update is called once per frame
     void Update () {
        //if(gameObject.tag == "Player") {
          if(Input.GetKeyDown(KeyCode.A)) {
           transform.Translate(new Vector3(-1, 0, 0) * Time.deltaTime * speed);
          }
        //}
  
       // if(gameObject.tag == "Player") {
          if(Input.GetKeyDown(KeyCode.D)) {
           transform.Translate(new Vector3( 1, 0, 0) * Time.deltaTime * speed);
          }
        //}
     }
 }
