Help with having certain attacks delay turns.

Hey guys, I working on a turn based combat system much like the ATB system from final fantasy. I want to be able to have certain abilities cause a delay in the battle timer for one turn until it fills again. I have gone over a load of ways to get this done but nothing works.

Could anyone offer any insight to a possible solution?

The load bar is titled "Progress Bar"

Code (CSharp):

1. void UpgradeProgressBar()
2.     {
3.         cur_cooldown = cur_cooldown + (Hero.currentAgility + 1 * Time.deltaTime);
4.         float calc_cooldown = cur_cooldown / max_cooldown;
5.         ProgressBar.transform.localScale = new Vector3(Mathf.Clamp(calc_cooldown, 0, 1), ProgressBar.transform.localScale.y, ProgressBar.transform.localScale.z);
6.         if (cur_cooldown >= max_cooldown)
7.         {
8.             currentState = TurnState.Addtolist;
9.         }
10.     }
