You want to change the same text's colour? Or print a new thing in a different colour every second?

same texts color

For the timing part, PeriodicTimer is probably the way to go For changing colour, Console.ForegroundColor To replace the text, you'd need to delete the current text and write the new text, or overwrite the old text Look into setting the position of the cursor

And the issue is...? With my solution, that is

krazycayOP•3y ago

it would make me reposition the cursor and then make me type where i want to change the color lol

Angius•3y ago

Ah, you want the text that user enters to change colour?

krazycayOP•3y ago

nono i want the logo lizthux to be color changing rainbow

Ah, huh It'll require hooking a little deeper into the console, then Probably Look into existing libraries like Spectre.Console Maybe they'll be helpful

krazycayOP•3y ago

Would it be transferrable across machines without downloading stuff on their machine?

Angius•3y ago

Of course When you publish a project, all the dependencies are compiled with it

krazycayOP•3y ago

ah i thought it was like a custom terminal you had to download and replace cmd prompt terminal with it not a c# library

Angius•3y ago

No, it's just a C# library that makes it a bit easier to work with console

krazycayOP•3y ago

alrighty how would i import it

Angius•3y ago

https://spectreconsole.net/quick-start As described in the documentation Or if you use Visual Studio (not Code) you can just open the package manager UI And search for spectre.console

krazycayOP•3y ago

where do i find package manager ui lmao

ahh i got it so how could i do the rainbow text?

Angius•3y ago

Check the documentation of Spectre.Console The Live thing should be of help

@Angius how would i do this lol

Angius•3y ago

.Live() takes a Widget So you'd use one of the Spectre.Console widgets Rows for example

krazycayOP•3y ago

You'll want something like this

await AnsiConsole.Live(new Markup("[red]uwu[/]")).StartAsync(async ctx =>
{
    while (true)
    {
        ctx.UpdateTarget(new Markup("[blue]uwu[/]"));
        ctx.Refresh();
        await Task.Delay(1000);

        ctx.UpdateTarget(new Markup("[green]uwu[/]"));
        ctx.Refresh();
        await Task.Delay(1000);

        ctx.UpdateTarget(new Markup("[red]uwu[/]"));
        ctx.Refresh();
        await Task.Delay(1000);
    }
});

await AnsiConsole.Live(new Markup("[red]uwu[/]")).StartAsync(async ctx =>
{
    while (true)
    {
        ctx.UpdateTarget(new Markup("[blue]uwu[/]"));
        ctx.Refresh();
        await Task.Delay(1000);

        ctx.UpdateTarget(new Markup("[green]uwu[/]"));
        ctx.Refresh();
        await Task.Delay(1000);

        ctx.UpdateTarget(new Markup("[red]uwu[/]"));
        ctx.Refresh();
        await Task.Delay(1000);
    }
});

This will swap between colors every second. I don't know how well this works with writing to the console simultaneously, though
