❔ Stop a loop when a key is pressed
I'm making an app with a while loop that is supposed to repeat over and over until the user hits a key. I alredy have a Key instance with the key I need.

I tried this:
bool loop = true;
while (loop)
{
//Loop Stuff
if (IsKeyDown(myKey))
{
loop = false;
}
}
and this
while (loop)
{
//Loop Stuff
if (IsKeyDown(myKey))
{
break;
}
}
But they didn't work.
Also, saw this in StackOverflow:
while(!Console.KeyAvailable)
{
//do work
}
But apparently that won't work unless I use a Console Application.
A few days ago I tried the code in this StackOverflow post, but I see it too complicated, and don't understand anything. ¿Could someone explain? I hate the idea of just pasting a piece of code I don't even understand.
did a quick test and that code seems to work
regarding your SO snippet
basicly what it does is that when the view opens the onloaded method gets called
in there is a loop that only fnishes when the cancelationtoken is set
the cancelationtoken get set on the onkeydownevent where before getting set it get checked if its the A key
Is this
system.windows.input.keyboard.iskeydown?
Perhaps it works the same as Unity and it returns true the frame it was pressed?
I believe this has something to do with your cancellation token not properly cancelling and not really because of your key being pressed. async void has no proper context and I get the feeling it straight up loses it, causing your cancellation token to not properly cancel.
Not sure how to explain this, but I am pretty sure I had this issue before and I had the exact same scenarioyes
ive got no clue about unity
i read his text as like he didnt even tried it yet since he doesnt understand it
You just gave me three answers while my whole message was aimed at @SantiJLM
I think I already tried this and didn't work
Lemme try it again
You should get used to debugging the problem a little better. Check using logging if
Keyboard.IsKeyDown(Key.A) ever reaches true, and see why it does not respond to it.I think I know why it does not work. The looping action includes a few System.Thread.Threading.Sleep. Probably that's why it doesn't get called.
I read in SO that I could make a timer, similar to Unity's update, and detect if my key is pressed every 100ms. That's when I realised how big my problem is.
The code I l'm making is going to be executed every time a button in the UI is pressed, so everything I do is inside of an event handler. Any idea of what I could do?
