How to get a random from an array????

Hi all,

I have an array, and I need to get a random index from it. The random method from javascript does not work in Unity, so what can I use instead??

Thank you... 8)

 

Something like...

Code (csharp):

1. var randIndex : int = Mathf.RoundToInt(Random.Range(0, maxIndex));

 

You don't need RoundToInt; Random.Range does integers by itself.

Code (csharp):

1. var randIndex = Random.Range(0, maxIndex);

(Assuming maxIndex is an int.)

If you were instantiating a random prefab from a list of prefabs assigned in the inspector, is this the method you'd use?

Always wondered about this.

Yep.

Code (csharp):

1. var somePrefabs : GameObject[];
2.  
3. function Start () {
4.    Instantiate(somePrefabs[Random.Range(0, somePrefabs.Length)]);
5. }

Thanks Eric thats totally cool 8)
