    Post Loops at same time c++ vrkiller

    Hello i was wondering about how i could make a loop that like runs on the same time

    if m=1
    cout << "lol";
    if get_key(space)

    remember this is just a example!

    would you please explain more! ? it somehow vague to me !(an possibly the others)
    you mean you are planning to make an infinite loop?

    it seems you'd like to do 2 things simultaneously.

    two ways:
    1. use threads
    2. use asynchronous processing (for example timers)
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.

    Or perhaps you could use non-blocking input (OS-specific).
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

    So is your goal to write 'lol' while the spacebar is held down?

    If so, you need to use an input method that doesn't wait for you to press a key, but instead just returns the answer immediately telling you if the key is currently down or not. That's "non-blocking input".
    Then you only have one loop. Pseudocode:
    while (true)
        if (key_is_down(KEY_SPACEBAR))
            cout << "lol";
    Of course you shouldn't make a busy-loop like this though.
