How do I check a List[0], when it's nothing?

I have made this function (inspired by the bugzerg arcade hack’n’slash tutorial)

		public static GameObject ClosestGameObject (string searchTag, Transform ClosestTo)
		{
			List<Transform> outPutList = new List<Transform>(); 
			outPutList.Clear();
			GameObject[] go = GameObject.FindGameObjectsWithTag(searchTag);
			foreach(GameObject goes in go)
			{
				outPutList.Add(goes.transform);
			}
			outPutList.Sort(delegate(Transform t1, Transform t2) {
					return Vector3.Distance(t1.position, ClosestTo.position).CompareTo(Vector3.Distance(t2.position, ClosestTo.position));
			});
			GameObject output = outPutList[0].gameObject;
			return output;
		}

But if I feed it a searchTag that isnt on any of the gameObjects in the scene, it gives me an error at line 13: Argument is out of range. Is there any way to check if the go variable contain anything? I know I can’t just simply write

GameObjecy[] go = GameObject.FindGameobjectsWithTag("Bleh");
if(go != null)
{
    // do stuff
}
else
{
    return null;
}

-thanks in advance :slight_smile:

if(go.Length > 0){
// do stuff
}else{
return null;
}

Just check to see how many items are in the array. If it returns 0, then there aren’t any.
