Question by NorthernEagle · Dec 30, 2013 at 08:18 PM · c#instantiate

Potential 4.3.1f1 bug Instantiate c#

Is this a potential bug, for the life of me I can't see the error in the code. Everytime I run it, Unity editor freezes and I need to force-quit. Any help would be greatly appreciated. Thanks

 using UnityEngine;
 using System.Collections;
 
 public class Enemy_Movement : MonoBehaviour
 {
     public GameObject enemy;
     public GameObject enemyClone;
     public GameObject playerToAttack;
     public int maxEnemies = 10;
 
     void Start ()
     {
         CreateEnemy ();
     }
 
     void CreateEnemy ()
     {
         for (int count = 0; count <= maxEnemies; count++)
         {
             GameObject enemyClone = (GameObject) Instantiate (enemy, new Vector3 (0, 2, 0), Quaternion.identity);
         }
     }
 }

Can you instantiate at different position ins$$anonymous$$d of same point like

 float spaceBetweenEnemies = 5.0f;
 
  void CreateEnemy ()
 {
     for (int count = 0; count <= maxEnemies; count++)
     {
       enemyClone = (GameObject) Instantiate (enemy, new Vector3 (count*spaceBetweenEnemies, 2.0f, 0), Quaternion.identity);
     }
 }

     CreateEnemy ();
     }
      
     void CreateEnemy ()
     {
     for (int count = 0; count <= maxEnemies; count++)
     {
     //GameObject enemyClone = (GameObject) Instantiate (enemy, new Vector3 (0, 2, 0), Quaternion.identity);
     //don't use a class back of a variable when you use GameObject then it need different variable name.
     enemyClone = Instantiate (enemy, new Vector3 (0, 2, 0), Quaternion.identity) as GameObject;
     }
     }
     }

Cool, thanks for the explanation. Problem is it still crashes Unity editor. The code works with debug.log, as soon as I uncomment the instantiate line, hard freeze. Is this a bug maybe?

Update: I split the EnemyGenerator and EnemyMovement scripts into 2 separate scripts and attached both to a LevelStatus empty gameobject and all works now. The C# code above works fine, looks like the script can't be on the same gameobject it links.

Thanks again.
