✅ 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

dragonOP•3mo 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•3mo ago

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

dragonOP•3mo ago

like this?

Kouhai•3mo ago

Yeah

dragonOP•3mo ago

Kouhai•3mo ago

Also

dragonOP•3mo ago

it doesnt change the colour yeah?

Kouhai•3mo ago

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

dragonOP•3mo 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•3mo ago

Show your full code please 😅

dragonOP•3mo ago

oh sure

Kouhai•3mo 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•3mo ago

The problem is most likely with ColourList

dragonOP•3mo ago

oh i see can you explain why?

Kouhai•3mo 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("█");

}

dragonOP•3mo ago

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

Kouhai•3mo ago

No, what you have is literally what I copy pasted

dragonOP•3mo ago

OH WAIT I SE

Kouhai•3mo 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•3mo ago

Yes, the problem is with it

dragonOP•3mo ago

it prints out this

Kouhai•3mo ago

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

dragonOP•3mo ago

colourlist does that

Kouhai•3mo ago

Yes, and that's the problem

dragonOP•3mo ago

oh Oh i se

Kouhai•3mo ago

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

dragonOP•3mo ago

its set to white after running

Kouhai•3mo ago

ForegroundColor is getting set to i

dragonOP•3mo ago

and its not set back to dark red

Kouhai•3mo ago

Yup

dragonOP•3mo 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•3mo ago

It's all good

dragonOP•3mo ago

ill be back after running some tests ig

Kouhai•3mo 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

dragonOP•3mo 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•3mo ago

Because it's outside the console screen 😜

dragonOP•3mo ago

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

Kouhai•3mo ago

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

dragonOP•3mo ago

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

dragonOP•3mo ago

drew a frog w it
