Choose a Random Tag

Question

Basically, I have five GameObjects each with a tag that is a number between 1 and 5. I'm trying to set the tagNumber integer = a random integer between 1 and 5. Then, I want it to set the target variable equel to a GameObject with the randomly selected tag. Any help is much appreciated.

 Transform target;
 public int tagNumber;
 
 
 void Awake () {
         tagNumber = Random.Range (1, 5);
         target = GameObject.FindWithTag (tagNumber).transform;
 
     }

GameObject.FindWithTag(string tag) needs a string parameter, not an int.

Create a string array to hold your tags e.g. string[] tagsArray = new string[5] //to hold 5 tags
You can declare the array as public and enter the tag strings in the Inspector, or declare them in the array initializer.
Use Random.Range to get a random index for the array e.g. for 5 tags the array length is 5, with indeces 0 to 4. So, use randomIndex = Random.Range (0, 5) //5 is excluded
Then: string randomTag = tagsArray[randomIndex]
Finally, target = GameObject.FindWithTag (randomTag).transform

At which point do I declare the "randomIndex" variable?

Sorry I overlooked that. You can declare it inline, i.e. int randomIndex = Random.Range (0, 5);
