Question by DoctorSauce · Jan 21, 2014 at 03:52 AM · gameobjectdestroyforeach

Checking to see if there are no more of a certain object in the scene?

So I have a script, which I will only share a small part of, but basically when this function is called I want it to delete all the objects with the tag "ground" and then once those are deleted, I want it to debug "done deletin' shiz". Here's the function:

 void DestroyLevel(){
     GameObject[] dungeons = GameObject.FindGameObjectsWithTag("ground");
     foreach (GameObject col in dungeons){
         Destroy (col);
         GameObject dungeon = col;
         if (dungeon != null){
             Debug.Log ("Still deletin' " + dungeon);
         }
         else {
             Debug.Log ("Done deletin' shiz");
         }
     }
 }

When I do this, I just get "still deletin' _" a bunch of times but I never reach "Done deletin' shiz" which is my goal. Any idea what is wrong with this script, I feel like I have tried everything but maybe I'm being an idiot. Any help is appreciated.

You have the right idea, but there is an issue here. You don't get a foreach cycle where 'col' will be null:

 void DestroyLevel() {
     GameObject[] dungeons = GameObject.FindGameObjectsWithTag("ground");
     foreach (GameObject col in dungeons) {
         Destroy (col);
         Debug.Log("Still deletin' " + dungen);
     }
     Debug.Log("Done deletin' shiz");
 }

I had tried this before, but calling another function in the place of "Done deletin' shiz" didn't work. But now I realize the error must be in the other function, so thank you.
