❔ 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.
SI tried this:
and this
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.
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.

Adid a quick test and that code seems to work
Aregarding 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

FIs this
system.windows.input.keyboard.iskeydown?FPerhaps it works the same as Unity and it returns true the frame it was pressed?
FI 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.FNot sure how to explain this, but I am pretty sure I had this issue before and I had the exact same scenario
Ayes
Aive got no clue about unity
Ai read his text as like he didnt even tried it yet since he doesnt understand it
FYou just gave me three answers while my whole message was aimed at @SantiJLM
SI think I already tried this and didn't work
SLemme try it again
FYou 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.SI 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.
SI 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.
SThe 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?
AWas this issue resolved? If so, run
/close- otherwise I will mark this as stale and this post will be archived until there is new activity.
