this part of the script stops working after 19 cycles because of the error.
the error is on this line.

if (ownTowers*.gameObject.GetComponent<TowerControler>().typeOfTower == TowerControler.towerType.broken)*

and here is the whole iEnummerator
IEnumerator TowerCheck ()

  • {*

  •  yield return new WaitForSeconds (0.5f);*

  •  GameObject [] ownTowers;*

  •  resourceManager RM = resourceManager.GetComponent<resourceManager> ();*

  •  ownTowers = GameObject.FindGameObjectsWithTag ("EnemyBT");	*

  •  Debug.Log ("own Towers: " + ownTowers.Length);*

  •  upResourceTimer ++;*

  •  upTowersTimer ++;*

  •  if (upResourceTimer >= 120 && resourceUpgrades < upResourceTo )*

  •  {*

  •  	RM.AIResourceRate -= 0.2f;*

  •  	upResourceTimer = 0;*

  •  }*

  •  if (ownTowers.Length >= 1f)*

  •  {	*

  •  	for (int i = 0; i <= ownTowers.Length; i++)*

  •  	{*

_ if (ownTowers*.gameObject.GetComponent().typeOfTower == TowerControler.towerType.broken)_
_ {_
_ RepairTeam = true;_
_ }_
_ }_
_ yield return new WaitForSeconds (5f); _
_ }_
_ StartCoroutine(TowerCheck());_
_ }*_

“ownTowers” is the array whose index goes out of range.

Probably due to this line:

for (int i = 0; i <= ownTowers.Length; i++)

Instead of “<=” use “<”.

for (int i = 0; i <= ownTowers.Length; i++)

Should be

        for (int i = 0; i < ownTowers.Length; i++)

Remember computer programmers start counting at 0, not 1. So the last index of an array with 20 elements is actually 19.
