✅ How to make program wait before executing next print line?

Console.WriteLine("This is line one");
// sleep 2 seconds
Console.WriteLine("This is line two");
// sleep 2 seconds
Console.WriteLine("This is line three");

Console.WriteLine("This is line one");
// sleep 2 seconds
Console.WriteLine("This is line two");
// sleep 2 seconds
Console.WriteLine("This is line three");

how do I get the program to wait in between each print statement? I know in Python its import time time.sleep() but this isn't python lol Thanks.

Thread.Sleep Method (System.Threading)

Suspends the current thread for the specified amount of time.

Yes

Mekasu0124OP•2y ago

I'm like no where near a beginner yet lol how would I do that?

Pobiega•2y ago

Thread.Sleep(2000) for now.

Mekasu0124OP•2y ago

ok bet. tyvm one more question please. How do I exit the program based off user's input?

if (userInput == "y")
{
  // continue program by calling necessary function to run again
}
else
{
  // exit program back to desktop
}

if (userInput == "y")
{
  // continue program by calling necessary function to run again
}
else
{
  // exit program back to desktop
}

I read over the link, but I'm not sure how to apply it to my code?

using System;
using System.Threading;

namespace MeksMathGame
{
    class Program
    {

        static void EndGame()
        {
            Console.WriteLine("You've Answered All The Questions! Would You Like To Play Again? Y/N");

            string userOption = Console.ReadLine();

            if (userOption.ToLower() == "y")
            {
                Console.WriteLine("You Selected To Play Again. Re-Launching Application!\n");
                Thread.Sleep(3000);
                DifficultySelection();
            }
            else
            {
                Console.WriteLine("You Selected To Not Play Again. Closing Application!\n");
                Thread.Sleep(3000);
            }
        }

                Thread.Sleep(3000);
            }
        }

I'd appreciate some more help please ❤️

Where is the key register supposed to go Where 'y' is ?

Mekasu0124OP•2y ago

in the else statement. It's just a little check to ask if you want to keep playing or not. If the user enters y or Y, then it recalls the game after 3000ms, otherwise i triggers the else part and closes the game so the part

else
{
  Console.WriteLine("You Selected To Not Play Again. CLosing Application!\n");
  Thread.Sleep(3000);
  // close entire application here
}

else
{
  Console.WriteLine("You Selected To Not Play Again. CLosing Application!\n");
  Thread.Sleep(3000);
  // close entire application here
}

Pink Elsa💖•2y ago

Well in this case you want the main game method to run in the while key isn't available loop

Mekasu0124OP•2y ago

I could give you the full code, but it's over 500 lines

Pink Elsa💖•2y ago

'''cs Console.WriteLine("Press ESC to stop"); do { while (! Console.KeyAvailable) { // here you just wait with rest of game }
} while (Console.ReadKey(true).Key != ConsoleKey.Escape); '''

Mekasu0124OP•2y ago

you're using apostrophes instead of back ticks, and that while loop doesn't make any sense to me

Pink Elsa💖•2y ago

Phone atm Can't seem to find them

Mekasu0124OP•2y ago

touch and hold teh apostrophe button to get the backtick if you're on apple

Pink Elsa💖•2y ago

Ahh

Mekasu0124OP•2y ago

on android, it should be it's own button https://pastebin.com/Ui9GMUr1 this is the full code

Pink Elsa💖•2y ago

I believe to run end game in the do while etc Since you're just waiting for a key press

Mekasu0124OP•2y ago

how can I do that when the EndGame() is triggered based off how many questions are left numberOfQuestions not waiting for a key press. waiting for a yes or no response

Pink Elsa💖•2y ago

Well a key doesn't take a "yes or no" it listens for whenever a key is pressed

Mekasu0124OP•2y ago

yes, I know. Again, not waiting for a key press. waiting for an entry of yes y or no n then the game either continutes (if part) or ends (else part)

Pink Elsa💖•2y ago

You can have a string set to the console.readline and check for that ? Oh you did that It's hard to see on phone but I think it goes within after you check for y

Mekasu0124OP•2y ago

the game closes in the else part of the if statement when the user enters anything but y. If the user enters y, it will restart the game. I need the part for the if statement so that if the user enters anything other than y, then it ends the game and closes the screen

Pink Elsa💖•2y ago

!= means not equal to If the user Input != "y" do something else quit I'm really bad at explaining code to people xd

Mekasu0124OP•2y ago

static void EndGame()
{
  // ask user if they want to play again
  Console.WriteLine("You've Answered All The Questions! Would You Like To Play Again? Y/N");
  // get user input
  string userOption = Console.ReadLine();
  // if the user enters 'y' for yes to play again
  if (userOption.ToLower() == "y")
  {
    // let them know that the game is restarting
    Console.WriteLine("You Selected To Play Again. Re-Launching Application!\n");
    // do a fake sleep to simulate game restarting
    Thread.Sleep(3000);
    // recall the first menu in the game
    DifficultySelection();
   }
   // if the user enters 'n' for no, or anything other than 'y'
   else
   {
      // tell them they selected to exit the game
      Console.WriteLine("You Selected To Not Play Again. Closing Application!\n");
      // fake simulation of game closing down
      Thread.Sleep(3000);
      // close the game
    }
}

static void EndGame()
{
  // ask user if they want to play again
  Console.WriteLine("You've Answered All The Questions! Would You Like To Play Again? Y/N");
  // get user input
  string userOption = Console.ReadLine();
  // if the user enters 'y' for yes to play again
  if (userOption.ToLower() == "y")
  {
    // let them know that the game is restarting
    Console.WriteLine("You Selected To Play Again. Re-Launching Application!\n");
    // do a fake sleep to simulate game restarting
    Thread.Sleep(3000);
    // recall the first menu in the game
    DifficultySelection();
   }
   // if the user enters 'n' for no, or anything other than 'y'
   else
   {
      // tell them they selected to exit the game
      Console.WriteLine("You Selected To Not Play Again. Closing Application!\n");
      // fake simulation of game closing down
      Thread.Sleep(3000);
      // close the game
    }
}

I just cannot find a working line of code to put after // close the game in the else part of the statement

Pink Elsa💖•2y ago

To quit the app?

Mekasu0124OP•2y ago

yes. it's a console based game. So when they do not want to play again, it should close the screen altogether

Pink Elsa💖•2y ago

Environment.Exit(0);

Mekasu0124OP•2y ago

I kept finding Application.Exit() lol idk why I kept finding that, but I never found anything to do with environment

Pink Elsa💖•2y ago

Try that

Mekasu0124OP•2y ago

I am currently doing that. Thank you so much for your help. I'll ping back if I run into anymore trouble 🙂 ❤️

Pink Elsa💖•2y ago

Did it work ?

Mekasu0124OP•2y ago

I haven't made it that far yet. Once I'm able to test it, I'll let you know

Pink Elsa💖•2y ago

Alright sure thing

Mekasu0124OP•2y ago

so I haven't gotten a chance to test out that code yet, but I have a noobie question. I generated this project through Visual Studio. In python, you can run a terminal command pip freeze > requirements.txt and that will create a file of all the dependencies inside your workspace if you're doing a virtual environment, and if not in a venv then it'll make the file of all your global libraries that you have pip installed. How do I do this in C#? I'm wanting to list the required dependencies in my read me file, but I'm not sure how to find them. I see a dependencies folder in my projects workspace, but when I expand those lists (folders), then expand for quite a bit, so how can I appropriately list the needed dependencies that the user will need to have installed if they clone the project from my git repo and try to compile and run themselves? The Environment.Exit(0); works, but it doesn't close the window. Instead it still waits for a keypress. Like it exits the game, and gives that message to press enter or any key to exit this window instead of just closing the window

kunio_kun•2y ago

It only happens when you are debugging if i remember correctly When you build or publish your application, all required libraries are included on the output directory. So references are actually specified in the project file, .csproj if its c# When they clone your repo, all packages from nuget can be restored with dotnet restore command, which the IDE usually does during project open, so you dont actually need to do the steps like you did in python
