instantiated gameobject problems c# (naming/creating)

Questions & Answers

The script i built up is supposed to create gameobjects in a loop, in this case, 10 gameobjects; but only one is created, and i can’t access it’s name… I’ve searched and my code looks right to me, so, any idea what’s wrong with it?

public string systemName = "Yulu";
public Color sunColor = Color.white;

public Transform planetPrefab;
private int planetAmount = 10;
private int planetOffset = 81920;
private float tempPos = 81920;

ArrayList planets = new ArrayList();

void Start ()
{
	sunColor = new Color(Random.Range(0f, 1f), Random.Range(0f, 1f), Random.Range(0f, 1f), 1f);
	
	for (int i = 0; i < planetAmount; ++i)	//10 is the max planet amount, this can't be more.
	{
		print (i);
		if (Random.value <= 0.5f)
		{
			GameObject planet = (GameObject)Instantiate(planetPrefab, new Vector3(0, 0, tempPos), Quaternion.identity);
			planet.name = systemName + "-" + i;
			planets.Add(planet);	//network
			planet = null;
		}
		
		
		
		tempPos += planetOffset;
	}
}

And yes, i dragged the prefab to the script in the inspector.

Nevermind i found the solution, i had to instantiate it as Transform, then using GameObject bla = thattransform.gameObject; and it worked.
