Questions & Answers

I want create a function that take any array of game Objects and return a random game object. I wrote these:

public GameObject[] items;

items = Resources.LoadAll<GameObject>("Game_Items") as GameObject[]; 

public GameObject getRandomItem()
{
	int randomIndex = Random.Range(0, items.Length);
	return items[randomIndex];
}

It works, but only for one array: Items. I want to know how can I modify this function that getRandomItem() takes any array, and return a random item from that array?

There you go:

public GameObject getRandomItem(GameObject[] items)
{
    return items[Random.Range(0, items.Length)];
}
//example of use:
void SomeFunction()
{
    GameObject[] someItems;
    someItems = Resources.LoadAll<GameObject>("Game_Items");
    GameObject randomItem = getRandomItem(someItems);
}
