Why would this while loop crash Unity?

[POLYGAMe]

I have the following code. It runs fine when I don’t put it inside a while loop, but I need to as I need to try spawning another car if the one attempted is active already. I can’t see anywhere that this would cause an infinite loop…

It’s being called in OnTriggerEnter, not within update.

function SpawnCar()
{
	while (!bCarSpawned)
	{
		for (var i = 0; i < iRandom; ++i)
		{
			iIndex = Random.Range(0, AICarArray.Length); 
			iRandomDir = Random.Range(1, 3);
			
			//print(Vector3.Distance(transform.position, SpawnerArray*.transform.position));*

•  	if (!AICarArray[iIndex].active)*
  

•  	{*
  

_ AICarArray[iIndex].transform.position.x = SpawnerArray*.transform.position.x; // Set car pos to spawner pos*_
_ AICarArray[iIndex].transform.position.y = SpawnerArray*.transform.position.y + 1;
AICarArray[iIndex].transform.position.z = SpawnerArray.transform.position.z;
AICarArray[iIndex].transform.rotation = SpawnerArray.transform.rotation;*_

* if (iRandomDir == 1)*
* {*
* AICarArray[iIndex].transform.tag = “AI_North”;
_ AICarArray[iIndex].transform.localEulerAngles.y -= 180;
AICarArray[iIndex].transform.position.x += 2; // Put on right side of the road*
//AICarArray[iIndex].rigidbody.velocity = transform.forward * -fInitialSpeedBoost; // Give initial boost_
* }*
* else*
* {*
* AICarArray[iIndex].transform.tag = “AI_South”;
_ AICarArray[iIndex].transform.position.x += -2; // Put on left side of road*
//AICarArray[iIndex].rigidbody.velocity = transform.forward * fInitialSpeedBoost; // Give initial boost_
* }*

* AICarArray[iIndex].SetActive(true);*
* bCarSpawned = true;*
* }*
* }*
* }*
}

Unity is not crashing. Unity is running like crazy carrying out your infinite loop. Line 34 will never trigger if all of the AICarArray items are already active.

A better solution would be to use a for loop to iterate through the entire collection looking for an inactive object. If none is found then a new one should be created or an error thrown.
