if (type==Type.Bomb){

Collider[] DestroyedObjects = Physics.OverlapSphere(this.transform.position,1.5f);
Instantiate(BombExplosion, this.transform.position, BombExplosion.transform.rotation);
foreach(Collider Blocks in DestroyedObjects){	
if(Blocks.tag == "Block"){
Destroy(Blocks.gameObject);}
if(Blocks == Bomb){
Instantiate(BombExplosion, Blocks.gameObject.transform.position, BombExplosion.transform.rotation);
Destroy(Blocks.gameObject);}}
Destroy(gameObject);}

Bomb → Is my prefab object.

BombExplosion → Is an explosion prefab.

First Instantiate creates BombExplosion at position of Type.Bomb as it needs to. Second Instantiate, Does NOTHING.

How can I make, if Bomb is in radius… Instantiate BombExplosion at position of Bomb, rotation to be same as prefab BombExplosion.

Why don’t you use tags on the bombs as well?

if(Blocks.tag == "Bomb")
{
    // Do bomby stuff
}

Otherwise, if there’s no way to remove a bomb without exploding it, why don’t you put the explosion stuff in the Bomb’s OnDestroy() callback?
