Question by joshuakeedy · May 06, 2019 at 05:50 PM · gameobjectdestroy objectpublic variabledestroy-clones

(Help) I need this script to destroy all game objects in a scene.

Hello, I am trying to make the following script destroy all the balloon clones in the scene but it is not working. If I use the line Destroy(Balloons) it gives me the error Destroying Assets is not permitted to avoid data loss.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using System.Linq;
 
 public class WipeOut : MonoBehaviour
 {
     //public GameObject WipeOutCounterInternal;
     NumOfWipeOutsCounter WipeOutCounterInternal;
     public GameObject WipeOutPrefab;
     public GameObject Balloons;
     bool allowWipeOut = false;
     public NumOfWipeOutsCounter numOfWipeOutsCounter;
     GameObject temp;
 
     // Start is called before the first frame update
     void Start()
     {
         numOfWipeOutsCounter = WipeOutCounterInternal.GetComponent<NumOfWipeOutsCounter>();
         temp = GameObject.Find("Balloons" + "(Clone)");
     }
 
     // Update is called once per frame
     void Update()
     {
         if (numOfWipeOutsCounter.WipeOuts >= 0)
         {
             allowWipeOut = true;
         }
 
         if (allowWipeOut = true && Input.GetKeyDown("space"))
         {
             Instantiate(WipeOutPrefab);
             numOfWipeOutsCounter.WipeOuts--;
             Destroy(temp);
 
             if(numOfWipeOutsCounter.WipeOuts == 0)
             {
                 allowWipeOut = false;
                 numOfWipeOutsCounter.WipeOuts = 0;
             }
         }
     }
 }

Many thanks, Josh Keedy.

Hello.

First, this line is not correct:

 temp = GameObject.Find("Balloons" + "(Clone)");

you forget the space, it should be with a space betweeen baloons and (Clone)

temp = GameObject.Find("Balloons" + " (Clone)");

Hello, I have made that change but I am still getting the error NullReferenceException: Object reference not set to an instance of an object and nothing is happening in the game.
