    var nums: Transform;

function Start () {


function OnMouseDown () {
	  this.rigidbody.AddExplosionForce(force, obj.transform.position, 5);
	  Instantiate(nums, transform.position, transform.rotation);


When posting questions here, it’s best to be more specific. Because this issue is obvious from the code, it’s not a big deal, but typically “here’s code, please help” is not a question that will be answered.

rigidbody.AddForce(Random.OnUnitSphereforce, ForceMode.Impulse);*
