    Maybe I've asked this before, maybe someone did, but I can't find the answer.

    How can I break out of a coroutine in C# and JavaScript? Not yield for a frame or a time interval or whatever. Just halt execution entirely. I think I've been doing it in a baad way.

    Thank you
    -Jon

    Code (csharp):
    1.  
    2. return;
    3.  
    Just place a return; whereever you want to break out of the coroutine. This will end execution of the coroutine completely. Similar to how return ends execution of a normal function.

    That's probably for JavaScript. That doesn't work in C#. How about:

    Code (csharp):
    1. yield break;
    ?

    edit: Googling and I think this is it. Now to change everything from yield return null; (Nasty!)

    ...from page 128 of the C# 4.0 Pocket Reference (which I highly recommend to anyone, beginner or pro):

    "The yield break statement indicates that the iterator block should exit early, without returning more elements..."

    So yes, yield break; is exactly what you should use. =)

    You cannot return from a coroutine, write yield break;
