Destroy within a certain radius?

Hello. When a condition happens, I want to destroy all objects with a certain tag that are within a certain radius of another object immediately, how would I do this? Thank you

There are several ways you could do this. Here is 1 example:

if(condition == true) {
     Collider[] nearObjects = Physics.OverlapSphere(somePosition, radius);
     //Return an array of all the colliders within a certain radius of some obj.

     foreach (Collider object in nearObjects) {
     //Iterate through the array

          if(object.tag == someTag) //Does the object have a certain tag.
              Destroy(object.gameObject);
              //If yes, then Destroy the gameObject the collider is attached to
     }

}

Or you could use Vector3.Distance. It would work very similarly, but you would first find an array of all the tagged objects, then check their distance from a desired point. The biggest advantage to this method would be that you don't have to have a collider attached to each object.
