c# - Set delay time to spawn object -

i have spawnscript (below) want create function within spawn, can put minimum , maximum delay time object can created inspector.

 using system.collections; using system.collections.generic;  public class spawncontroller : monobehaviour {      public float maxwidth;     public float minwidth;      public float mintime;     public float maxtime;      public float ratespawn;     private float currentratespawn;      public gameobject tubeprefab;      public int maxspawntubes;      public list<gameobject> tubes;      // use initialization     void start ()     {           (int = 0; < maxspawntubes; i++) {             gameobject temptube = instantiate (tubeprefab) gameobject;             tubes.add (temptube);             temptube.setactive (false);          }          currentratespawn = ratespawn;      }      // update called once per frame     void update ()     {          currentratespawn += time.deltatime;         if (currentratespawn > ratespawn) {             currentratespawn = 0;             spawn ();         }     }      private void spawn ()     {          float randwitdh = random.range (minwidth, maxwidth);          gameobject temptube = null;          (int = 0; < maxspawntubes; i++) {             if (tubes [i].activeself == false) {                 temptube = tubes [i];                 break;             }         }          if (temptube != null)             temptube.transform.position = new vector3 (randwitdh, transform.position.y, transform.position.z);         temptube.setactive (true);     } } 

you use time.realtimesincestartup timestamps - kinda fit way atm. or use coroutines unity , 1 better learns use them late. or use invoke shortest way of doing it.

edit: ratespawn = random.range(mintime, maxtime); inside if statement in update, fit current approach most.
