Spawning objects around a point

Hi!

First create that "cube made of smaller cubes" and put it into a prefab.

Next, copy the code below (this is a code I found on unity answers too and just modified it, credits to the owner of the code and I forgot who he/she is) and paste it into a new JS script.

Then, create an empty game object and drag the JS script in it.

Select the prefab that you've created and add a rigidbody on it.

Once the prefab has a rigidbody, click the empty game object with the script, apply the prefab that you've created to that script.

Make sure that the "cube made of smaller cubes" you've made is positioned at (0,0,0)

 var timer : float = 0.0;
 var spawning : boolean = false;
 var prefab : Rigidbody;
 var spawn1 : Transform;
 
   
 function Update () {
  //check if spawning at the moment, if not add to timer
  Debug.Log(Application.loadedLevelName);
  if(!spawning){
   timer += Time.deltaTime;
  }
  //when timer reaches 2 seconds, call Spawn function
  if(timer >= 2){
   Spawn();
  }
 }
  
 function Spawn(){
  //set spawning to true, to stop timer counting in the Update function
  spawning = true;
  //reset the timer to 0 so process can start over
  timer = 0;
  
  //select a random number, inside a maths function absolute command to ensure it is a whole number
  var randomPick : int = Mathf.Abs(Random.Range(1,3));
  
  //create a location 'Transform' type variable to store one of 3 possible locations declared at top of script
  var location : Transform;
  var thingToMake : Rigidbody;
  //check what randomPick is, and select one of the 3 locations, based on that number
  if(randomPick == 1){
   location = spawn1;
  
   Debug.Log("Chose pos 1");
  thingToMake = Instantiate(prefab, location.position, location.rotation);
   
  
  }
  
  
  //halt script for 1 second before returning to the start of the process
  yield WaitForSeconds(1);
  //set spawning back to false so timer may start again
  spawning = false;
 }
