I need to destroy an instantiated prefab

Questions & Answers

My script goes as follows

private void Explode()
{
Collider thingsWeHit =
Physics.OverlapSphere(transform.position,
explosionRadius,
explosionDetectionMask);

	for(int i = 0; i < thingsWeHit.Length; i++)
	{
		Rigidbody hitRigidbody = thingsWeHit*.rigidbody;*

  •   	if(hitRigidbody != null)*

  •   	{*

  •   		hitRigidbody.AddExplosionForce(explosionForce,*

  •   		                               transform.position,*

  •   		                               explosionRadius,1f,ForceMode.Impulse);*

  •   		if(hitRigidbody.gameObject.layer == LayerMask.NameToLayer("Enemy"))*

  •   		{*

  •   			Destroy(hitRigidbody.gameObject, .75f);*

  •   		}*

  •   		else if(hitRigidbody.gameObject == null)*

  •   		{*

  •   			Destroy(this.gameObject, 2f);*

  •   		}*

  •   	}*

  •   }*

I want it to destroy itself after 2 seconds if it doesnt collide with any rigidbody so it doesnt fly on forever. Any help would be appreciated

Try this

private void Explode() { 
Collider[] thingsWeHit = Physics.OverlapSphere(transform.position, explosionRadius, explosionDetectionMask);

    for(int i = 0; i < thingsWeHit.Length; i++)
    {
       Rigidbody hitRigidbody = thingsWeHit*.rigidbody;*

if(hitRigidbody != null)
{
hitRigidbody.AddExplosionForce(explosionForce,
transform.position,
explosionRadius,1f,ForceMode.Impulse);
if(hitRigidbody.gameObject.layer == LayerMask.NameToLayer(“Enemy”))
{
Destroy(hitRigidbody.gameObject, .75f);
}
}
}
if(thingsWeHit.length == 0)
{
Destroy(this.gameObject, 2f);
}

}
–EDIT-- This code will destroy your object when u call explode function and an abject doesn’t hit any enemy at this moment

why not just put

void Start()
{
Invoke("SomeMethod", 2.0f);
}

void SomeMethod()
{
Destroy(gameObject); //if you want the script to be destroyed
// put 'Destroy(this);' instead
}

anywhere in your script pretty much. This should get the job done.
