Question by MoiseC · Jul 20, 2021 at 02:59 PM · randomization

Shuffle the positions of objects

Hi ! I try to make a shuffle function to Shuffle the positions of objects with an array. I made this little code work but it only shuffle the order of the elements in the array but not the positions of the objects themselves. I would really appreciate help for this ;) !

 public class GMTrace : MonoBehaviour
 {
 
     [SerializeField] Transform[] Starts = new Transform[4];
     
     [SerializeField] Transform[] Ends = new Transform[4];
     
     private void Start()
     {
         
         ShuffleStarts();
     }
 
 
     
     private void ShuffleStarts()
     {
         for(int i =0; i<Starts.Length; i++)
         {
             int rnd = Random.Range(i, Starts.Length);
             Transform temp = Starts[i];
 
             Starts[i] = Starts[rnd];
             Starts[rnd] = temp; 
         }
     }
 }

If you want to swap the positions, then:

  • the temp variable should be a Vector3 and should store Starts[ i ].position

  • do Starts[ i ].position = Starts[ rnd ].position;

and Starts[ rnd ].position = temp;

That will "shuffle" the positions.
