How to stop co-routine?

问题

When two co-routines are running, how do you stop the first co-routine?

GLOBALS.stableTime = 5;

IEnumerator StableWaittingTime ()
{
        yield return new WaitForSeconds (1f);
        if (GLOBALS.stableTime == 0) {
                GameManager.instance.LevelFaildMethod ();
        } else {
                GameManager.instance.stableWaittingTime.text = GLOBALS.stableTime.ToString ();
                GLOBALS.stableTime--;
                StartCoroutine ("StableWaittingTime");
        }
}

@Imapler answer is almost all you need. I would just add that StopCoroutine method of MonoBehaviour is overloaded and has 3 types of parameters, so it is possible to stop many coroutines of same name. For your need here, just use yield break; like this:

void Start () 
{
    StartCoroutine (StableWaittingTime ());
}

IEnumerator StableWaittingTime ()
{
    yield return new WaitForSeconds (1f);
    if (false) 
    {
        // do something
    } 
    else 
    {
        // do something
        StartCoroutine (StableWaittingTime ());
        yield break;
    }
}

There are three ways to stop coroutines. First is to call StopAllCoroutines. The second is to call StopCoroutine. And the third is to do a yeild break from within the coroutine.

StopAllCoroutines stop all coroutines, StopCoroutine stop all coroutines with a give name and yeild break stops that coroutine. Worth noting is that both StopAllCoroutines and StopCoroutine can only stop a coroutine when the coroutine reaches a yield return.

So if you have two coroutines with the same name and you want to stop the one you are executing in you do yeild break. Interestingly, if you want to stop every other coroutine than the one you are executing in you call StopCoroutine from within that coroutine.
