unity3d - Unity 5.0.1 Completely Stopping a Coroutine -

alright running slight issue, basically, have coroutine contains for-loop. can call stopcoroutine , startcoroutine methods successfully, of course, pauses , unpauses coroutine. there way stop , restart it? end-goal here able start coroutine, kill @ user's discretion, , restart beginning time, @ user's discretion. accomplishable? thanks.

to "rewind" coroutine, call coroutine method again same parameters. if want save these parameters, can use closures:

public class coroutineclosureexample : monobehaviour {     private system.func<ienumerator> createcoroutinefactory(int someint, float somefloat)     {         return () => coroutineyouwant(someint, somefloat);     }      private ienumerator coroutineyouwant(int someint, float somefloat)     {         for(int = 0; < someint; i++)         {             yield return new waitforendofframe();         }     }      private system.func<ienumerator> m_currentcoroutinefactory;     private ienumerator m_currentcoroutine;      public void setcoroutineparameters(int someint, float somefloat)     {         m_currentcoroutinefactory = createcoroutinefactory(someint, somefloat);     }      public void restartcurrentcoroutine()     {         if (m_currentcoroutine != null)         {             stopcoroutine(m_currentcoroutine);             m_currentcoroutine = null;         }         if (m_currentcoroutinefactory != null)         {             m_currentcoroutine = m_currentcoroutinefactory();             startcoroutine(m_currentcoroutine);         }     } }
