I am trying to make a Plane Shooter game.The part that i need help is enemy movement.

Code (CSharp):

1. using UnityEngine;
2.  
3. public class EnemyMovement : MonoBehaviour
4. {
5.     public float speed;
6.     public bool MoveRight;
7.  
8.  
9.  
10.  
11.     void Update()
12.     {
13.  
14.  
15.         if (MoveRight)
16.         {
17.  
18.             transform.Translate(2 * Time.deltaTime * speed, 0, 0);
19.             transform.localScale = new Vector2(-6, 8);
20.         }
21.         else
22.         {
23.  
24.             transform.Translate(-2 * Time.deltaTime * speed, 0, 0);
25.             transform.localScale = new Vector2(6, 8);
26.         }
27.  
28.        
29.  
30.     }
31.  
32.     void OnTriggerEnter2D(Collider2D trig)
33.     {
34.  
35.  
36.         if (trig.gameObject.CompareTag("Wall"))
37.         {
38.  
39.             if (MoveRight)
40.             {
41.  
42.                 MoveRight = false;
43.  
44.             }
45.             else
46.             {
47.  
48.                 MoveRight = true;
49.  
50.             }
51.         }
52.  
53.  
54.     }
55.  
56.  
57.  
58.  
59.  
60. }
61.  

Error is : "Tag : Wall is not defined"

 

You're using CompareTag for "Wall" but you haven't defined Wall as a tag. When you click a gameObject and look at the inspector, the top has a tag drop down. You should have Wall there, and if not, you need to create it.

 

Edit/Project Settings...


And then select the game objects what you want to tag as "Wall" and tag here:

 

Yeah you are right.I made a layer instead of tag.Thank you for helping

 

Sorry, I didn't saw yours.Thank you too.
