✅ Is it possible to ask check for a keypress without pausing the whole console?

Kinda new to c# so i dont rlly know alot, but i started a project and i literally have no clue how to ask for a keypress w out pausing and waiting for one, ive seen examples on stack like
Task.Factory.StartNew(() => Console.ReadKey(true)).Wait(TimeSpan.FromSeconds(0.2)); but i cant assign that to var key to use as controls etc, if anyone wants to check through my code more i can send screenshtos or try open a git

Check Console.KeyAvailable before calling Console.ReadKey

dragon•3w ago

uhh lemme try that kinda worked the code runs smoothly but i dont think it takes input ima go check it out some more

Kouhai•3w ago

It gets input Console.KeyAvailable returns true if there's data in stdin, and Console.ReadKey will read a key from stdin

dragon•3w ago

like this?

Kouhai•3w ago

Yeah

dragon•3w ago

Kouhai•3w ago

Also

dragon•3w ago

it doesnt change the colour yeah?

Kouhai•3w ago

You don't need if (Console.KeyAvailable == true) you can just do if (Console.KeyAvailable)

dragon•3w ago

fair point hold on im gonna go use breakpoints and see if that is ever true brb its always false im trying to make mspaint in console atm bc im bored at school and had no idea what to do

Kouhai•3w ago

Show your full code please 😅

dragon•3w ago

oh sure

Kouhai•3w ago

If it's too long $paste

i took some stuff from stack overflow, like to know where cursor is etc but i hard coded parts so you might need to change the numbers for ur screen its prolly insanely inefficient but this is js a first draft for school atm also thank you sm kouhai ALSO I LITERALYL STARTED MAKING IT TODAY SO NOT MUCH HAS BEEN MADE i think my code killed them

Kouhai•3w ago

The problem is most likely with ColourList

dragon•3w ago

oh i see can you explain why?

Kouhai•3w ago

Well

for (int i = 0; i < Colours.Length; i++) // Iterate from 0 to Colours.Length which is 16, meaning the last value of i will be 15
{
    if (i % 2 == 0)
    {
        Console.SetCursorPosition(2, (Console.WindowHeight / 2 - Colours.Length / 2) + i);
    }
    else { Console.SetCursorPosition(4, (Console.WindowHeight / 2 - Colours.Length / 2) + i); }
    Console.ForegroundColor = (ConsoleColor)(i); // Set the foreground color to i, which means the last color would be white
    Console.WriteLine("█");

}

for (int i = 0; i < Colours.Length; i++) // Iterate from 0 to Colours.Length which is 16, meaning the last value of i will be 15
{
    if (i % 2 == 0)
    {
        Console.SetCursorPosition(2, (Console.WindowHeight / 2 - Colours.Length / 2) + i);
    }
    else { Console.SetCursorPosition(4, (Console.WindowHeight / 2 - Colours.Length / 2) + i); }
    Console.ForegroundColor = (ConsoleColor)(i); // Set the foreground color to i, which means the last color would be white
    Console.WriteLine("█");

}

dragon•3w ago

yeah um i have it so you can go back and forth tho

Kouhai•3w ago

No, what you have is literally what I copy pasted

dragon•3w ago

OH WAIT I SE

Kouhai•3w ago

void ColourList()
{

    for (int i = 0; i < Colours.Length; i++)
    {
        if (i % 2 == 0)
        {
            Console.SetCursorPosition(2, (Console.WindowHeight / 2 - Colours.Length / 2) + i);
        }
        else { Console.SetCursorPosition(4, (Console.WindowHeight / 2 - Colours.Length / 2) + i); }
        Console.ForegroundColor = (ConsoleColor)(i);
        Console.WriteLine("█");

    }
}

void ColourList()
{

    for (int i = 0; i < Colours.Length; i++)
    {
        if (i % 2 == 0)
        {
            Console.SetCursorPosition(2, (Console.WindowHeight / 2 - Colours.Length / 2) + i);
        }
        else { Console.SetCursorPosition(4, (Console.WindowHeight / 2 - Colours.Length / 2) + i); }
        Console.ForegroundColor = (ConsoleColor)(i);
        Console.WriteLine("█");

    }
}

I REPEATED MYSELF IN THE CODE THANK YOU SM WAIT NO im dumb this is for a seperate thing uhh hold on

Kouhai•3w ago

Yes, the problem is with it

dragon•3w ago

it prints out this

Kouhai•3w ago

You're setting ForegroundColor to i to display the colors, but ForegroundColor is not being reset to the previous color

dragon•3w ago

colourlist does that

Kouhai•3w ago

Yes, and that's the problem

dragon•3w ago

oh Oh i se

Kouhai•3w ago

Let's say before exeuting the method that ForegroundColor is DarkRed We enter the function

dragon•3w ago

its set to white after running

Kouhai•3w ago

ForegroundColor is getting set to i

dragon•3w ago

and its not set back to dark red

Kouhai•3w ago

Yup

dragon•3w ago

so when console prints other things hold on ah okay ill go figure how to get it to stay thank you so so much kouhai im a bit dum at times

Kouhai•3w ago

It's all good

dragon•3w ago

ill be back after running some tests ig

Kouhai•3w ago

Also, your program will crash here Console.SetCursorPosition(defPnt.X * Console.WindowWidth / 1919, defPnt.Y * Console.WindowHeight / 1079); Because sometimes the cursor will be outside the console screen

dragon•3w ago

yeah it only crashes if i hover over x like the red close tab otherwise it runs fine so it doesnt rlly matter for rn

Kouhai•3w ago

Because it's outside the console screen 😜

dragon•3w ago

yeah lol but if ur goin on X your shutting the program down anyways

Kouhai•3w ago

Well...a program shouldn't crash because the user is hovering over X

dragon•3w ago

ill fix it after i get everything else working thats like my lowest priority problem rn 😭 OKAY IT WORKS

dragon•3w ago
