How can i add properties for each element in array of gameobject ?

           if (parent)
               objInstance.transform.parent = this.transform;

       }

       createdObjects = GameObject.FindGameObjectsWithTag(objname);

       if (objname == "Teleportation Booth")
           UpdateList(false);
   }

   private void UpdateList(bool destroy)
   {
       GameObject go = GameObject.Find("Main Camera");
       var list = go.GetComponent<PatrolOverTerrain>().Targets;
       if (destroy == false)
       {
           list.AddRange(createdObjects);
           go.GetComponent<PatrolOverTerrain>().Targets = list;
       }

       if (destroy == true)
       {
           list.Clear();
           go.GetComponent<PatrolOverTerrain>().Targets.Clear();
       }
   }
}

Instead attaching the script to every gameobject i will want to clone i want to use array of objects.

For example let’s say i have in the array 2 objects now i want in the inspector to have under each element it’s own properties. And when i will set the properties as children for each element it will take effect for the specific element only.

Instead general properties for all the elements to make this properties from Y Offset until the last Set Rand Scale Z Max to be children for each element. So i can set the properties per element.

So i can expand each element and see his properties.

Btw: How can i change the random for example that: Set Rand Scale X Min and Set Rand Scale X Min will be on one line and not two lines ? Like:

Set Rand Scale X Min Max Set Rand Scale Y Min Max Set Rand Scale Z Min Max

I don’t think you can expand a game object to see its properties. Maybe a custom drawer could be used to expand an object if it had a certain script you want to look at (I don’t know for sure, but sounds plausible).

If you’re talking about the same line in the inspector, you could make those Rand Scale X,Y,Z a Vector3 and it would show up on 1 line, if that’s what you were asking.
