Trouble with Tag not being defined.

Hi,

in the following code:

Code (CSharp):

1. public string enemyTag = "Enemy";
2.  
3. void UpdateTarget()
4.     {
5.         GameObject[] enemies = GameObject.FindGameObjectsWithTag(enemyTag);
6.         float shortestDistance = Mathf.Infinity;
7.         GameObject nearestEnemy = null;
8.         foreach (GameObject enemy in enemies)
9.         {
10.             float distanceToEnemy = Vector3.Distance(transform.position, enemy.transform.position);
11.             if (distanceToEnemy < shortestDistance)
12.             {
13.                 shortestDistance = distanceToEnemy;
14.                 nearestEnemy = enemy;
15.             }
16.         }
17.  
18.         if (nearestEnemy != null && shortestDistance <= range)
19.         {
20.             target = nearestEnemy.transform;
21.         }
22.         else
23.         {
24.             target = null;
25.         }
26.  
27.     }

I would receive an error on line 5: UnityException: Tag: Enemy is not defined.

How ever by creating a public string called enemyTag = "Enemy"; where Enemy is an object in the game. Calling it from GameObject.FindGameObjectsWithTag(enemyTag); seems to not work.

While the same principe works from different scripts running in the game.


(This script is from a tower defense tutorial on youtube. Im trying to learn basics and best systems for these types of games and am manualy typing the code provided by the video. I checked for typo's and errors by comparing the video's project and mine. But no differences.)

P.S. The code is slimmed down theres allot more i can post here but i will do if required for extra clearance.


Thanks in Advance

Did you create a tag called "Enemy"?

In your scene, click on pretty much anything. In the inspector, you'll see tag. Use the drop down and check that you have an Enemy tag.

 

You have that variable as public, so it's possible it's empty in the inspector, which will overwrite your initialized value of "Enemy" potentially. So double check you have an Enemy tag created, and double check your inspector value.

 

I feel silly. @Brathnann i forgot... Thats like basics if you point to a tag then you shouldve created a tag...

 

Thank you!
