Hi guys. I'm kind of new to this. I want cubes to spawn randomly in the game every, let's say, 5 seconds. I have this code so far:

var object:Transform;
var x = 12;
var z = 12;
var y = 5;

function Update () {    

    var position = Vector3(Random.Range(-x, x), y, Random.Range(-z, z));
    Instantiate(object, position, Quaternion.identity);

}

I tried using yield WaitForSeconds(5.0) but it messed things up... Thank you in advance.

you can't use yield in Update(). you should do it in start(), Awake() or custom functions like this:

function Start(){
  DoInstantiate();

}
function DoInstantiate(){
  while (true){
    yield WaitForSeconds(5.0);
    var position = Vector3(Random.Range(-x, x), y, Random.Range(-z, z));
    Instantiate(object, position, Quaternion.identity);
  }

}

C# code I would recommend:

public GameObject spawnObject;
public float xRange;
public float zRange;
public float y;
public float spawnRate;

void Awake ()
{
    InvokeRepeating("Spawn", 0f, spawnRate);
}

void Spawn () 
{
    Instantiate(spawnObject, new Vector3(Random.Range(-xRange, xRange), y, Random.Range(-zRange, zRange)), Quaternion.identity);
}

ok in java script for unity this is how you get the script to spawn a item and when it gets destroyed to let it spawn agein.

var bullet : GameObject;

var bulletbackup : GameObject;

function Update () { if( Input.GetButton(“fire1”))

{bulletbackup = Instantiate(bullet, transform, rotation,))}

}

Now to make a spawn time on a object is like this

var spawntime : float = 1;

var resetnumber : float = 10;

function Update (){Time.deltaTime * ++spawntime;

}

That might help but the best way Ive made a spawn time is by useing the animation tool

But I hope this helps.

Oh and im not for sure on the script with the spawn time but that is done in Java
