Array index is out of range when spawning prefabs randomly

Questions & Answers

FYI: I am newish to Unity

I found a bit of code on the internet and tweaked it a little bit. To me, everything looks like it should be working, but I keep receiving an ‘IndexOutOfRangeException: Array index is out of range’.

After assigning the script, I set the size to 7 and then attach my prefabs respectively.

What am I overlooking to keep receiving this error message?

#pragma strict
var spawnObjects : GameObject[];
var newSpawn : Transform; 
 
function Start () 
	{	
	 	//initialize spawning points array
 	 	spawnObjects = GameObject.FindGameObjectsWithTag("Respawn");
	}
 
// Starting in 0.5 seconds, a projectile will be launched every 0.3 seconds
InvokeRepeating("LaunchProjectile", 0.5, 0.3);
 
function LaunchProjectile () 
	{
 		//randomly return position of a spawn point
 		var spawnPos = spawnObjects[(Random.Range(0, spawnObjects.length))].transform.position;
 
 		Instantiate(newSpawn, spawnPos, Quaternion.identity);
	}

I’m guessing you don’t have any gameobjects correctly tagged with Respawn. One frequent cause of that is to accidentally put them on a layer rather than tag them.
