How to Create a Rock-Paper-Scissors Game Using CMD


Rock-Paper-Scissors is a classic game that can be played anywhere, anytime. With CMD, you can create a simple text-based version of the game. In this article, we'll guide you through the steps to create a Rock-Paper-Scissors game using CMD.

Step 1: Understanding the Basics
Before we dive into the project, let's cover some basics:

- CMD (Command Prompt) is a command-line interpreter that allows you to interact with your operating system.
- Batch scripting is a way to automate tasks using CMD.
- Rock-Paper-Scissors is a game where two players simultaneously throw one of three hand signals: rock, paper, or scissors.

Step 2: Setting Up the Environment
To create our Rock-Paper-Scissors game, we'll need:

- A text editor (e.g., Notepad)
- CMD (Command Prompt)

Step 3: Creating the Game Script
Open a new file in your text editor and save it as "rock_paper_scissors.bat". This will be our batch script. Add the following code:
```
@echo off
set /a player_score=0
set /a computer_score=0

:game_loop
echo Welcome to Rock-Paper-Scissors!
echo Player score: %player_score%
echo Computer score: %computer_score%
echo.
echo 1. Rock
echo 2. Paper
echo 3. Scissors
echo.
set /p player_choice=Enter your choice (1, 2, or 3):

if %player_choice%==1 (
    set player_throw=Rock
) else if %player_choice%==2 (
    set player_throw=Paper
) else if %player_choice%==3 (
    set player_throw=Scissors
) else (
    echo Invalid choice. Please try again.
    goto game_loop
)

set /a computer_throw=%random%%%3 + 1
if %computer_throw%==1 (
    set computer_throw=Rock
) else if %computer_throw%==2 (
    set computer_throw=Paper
) else if %computer_throw%==3 (
    set computer_throw=Scissors
)

echo Computer throws: %computer_throw%
echo.

if %player_throw%==%computer_throw% (
    echo It's a tie!
) else if %player_throw%==Rock (
    if %computer_throw%==Scissors (
        echo Rock crushes Scissors! You win!
        set /a player_score+=1
    ) else (
        echo Paper covers Rock! You lose.
        set /a computer_score+=1
    )
) else if %player_throw%==Paper (
    if %computer_throw%==Rock (
        echo Paper covers Rock! You win!
        set /a player_score+=1
    ) else (
        echo Scissors cuts Paper! You lose.
        set /a computer_score+=1
    )
) else if %player_throw%==Scissors (
    if %computer_throw%==Paper (
        echo Scissors cuts Paper! You win!
        set /a player_score+=1
    ) else (
        echo Rock crushes Scissors! You lose.
        set /a computer_score+=1
    )
)

echo.
echo Do you want to play again? (y/n)
set /p play_again=

if %play_again%==y (
    goto game_loop
) else (
    exit
)
```
Let's break down the script:

- `@echo off` turns off command echoing.
- `set /a player_score=0` and `set /a computer_score=0` initialize the scores.
- The `game_loop` label marks the start of the game loop.
- The script prompts the player to enter their choice (rock, paper, or scissors).
- The script generates a random computer throw (rock, paper, or scissors).
- The script determines the winner based on the game rules.
- The script updates the scores and asks if the player wants to play again.

Step 4: Running the Script
Save the script and navigate to the folder containing your script. Run the script by typing "rock_paper_scissors.bat" in CMD.

Step 5: Play the Game!
After running the script, you'll be prompted to enter your choice (rock, paper, or scissors). Enter your choice and see if you win or lose. Play again to try your luck!
