How to Build a Simple Computer Game Using Batch Script

Batch Script is a basic scripting language that runs on any Windows or MS DOS operating system, the functions are based on the commands for the command lines in these operating systems. Also its pretty cool! Making a game with this script is not that difficult, all it takes is a little time and creativity. Please note: In order for this project to work properly, you will need Windows 2000 or higher, as this will not work in earlier versions of Windows or MS DOS, since MS DOS is not compatible with modern batch scripts.

    Decide on a game. Before deciding to make a shoot-em-up game or point-and-click game, know that even with MS DOS 8, batch script has serious limitations to its capabilities. You will not be able to create more of a game than a text-based game. It can be a quiz or a scenario game, but you will have only text. As to whether or not you want to have ASCII graphics is up to you, but the game will still be based entirely on text input.

    Learn the script. The script is not that hard to learn, you may even learn it simply by looking at a program. To know any scripting language you may need to know some basic commands in your computer's command line. For this command line, the basic commands that you will need are:
    • echo
    • color
    • title
    • goto
    • if
    • set
    • labeling (not a command, but how to label)

    Learn how to use the above commands.
    • The echo command is used to print out text to the console. Below, the echo command prints out "Hello, world!":

    • The color command is used to change the color of the text in the command line. This isn't very useful, and probably shouldn't be focused on until you have finished the game itself, but the results of the color change can be quite appealing. Colors in DOS command lines are numbered, there is a table of the colors at the end of this article. The following command will change the text color to black background with green text:

    • The title command simply changes the name of the window on the title bar and task bar, and is by no means useful, however, it can make your program look professional. Using it like so will change the title of the window to "Fun Program":

    • The goto command is used to go to a certain part of the program. You will be using it to determine what will happen when certain answers are chosen from questions. To use the goto command to go to a label called "WRONG":

    • The if command is used to determine what will happen if a certain event occurs. After the if statement (if [something]), a command follows. At the if statement, if a certain event is true, the command in the statement will be carried out. You will be using this statement to determine which goto command is to be used. This if statement will be true if the input is equal to 12:

    • The set command is actually quite complicated, since it may be used in many ways. As for now, all you need it for is to get the computer to receive input. To do this:
      Image titled 610238 3b6
    • Finally, labeling. Labeling can name certain parts of the program so that you may use the goto command. You can name certain sections of the program anything, so long as the name isn't a command. To label a section "main", type the following:

      • Labeled sections include the label itself and all code that follow it until another label is present or the file reaches the end! Make sure you place the label before the section being labeled, and another label following it so that the computer understands what section is labeled! Example below:

         @echo off :LABEL1 echo THIS IS A TEST OF TEXT set/p input=THIS IS A TEST INPUT_ if %input%==1 goto LABEL1 goto LABEL2 :LABEL2 echo TEST 
      • The first line of the above program may have been confusing to you. This line turns off the display of the code inside the file, so it doesn't look like it was all typed out on a console. As of now that is unimportant, right now you should be determining what the above program will do(ignore the first line). The program will display text saying "THIS IS A TEST OF TEXT", then it will prompt for input. If the input is "1"(meaning you typed in 1), the program will return to LABEL1 and the commands below it will repeat. If the condition in the if statement is not met, the computer will print text to the console "TEST". Copy the above program into two different windows running notepad. In one, save it as TEST1 in any folder and run it. Notice how the text is displayed. In the second window, erase the first line and save it as TEST2 and run it. Notice the difference?
    • Once you have a general understanding of how the above commands may be used, you may move on to the next step.

    Start scripting your game. It is suggested that a beginner use notepad, but if you would like to use MS DOS EDIT, that's fine, too. It is also suggested to a beginner to begin with a basic quiz game, so this is what this article will show you how to do. Remember to start by turning off the echo. Then introduce your game with some text through the echo command, then use set to allow input with the goto command. This may sound confusing, so look above (Note: the command REM creates comments, i.e. notes for the developer that won't show in the final result):

    Work on the instructions page. At this point, you should save your file(save as something.bat), and put it in a folder that you created for the game. After saving it, run it and make sure it works.
    • From this point on you will be having multiple files per game (especially if you want to have ASCII graphics). You can get the batch script to print out the contents of any file on the screen with the type command. The below will print the contents of TEST.txt:
      Image titled 610238 5b1
      • It's important to remember to include the file extension, or the command may not work properly.
    • Create an instructions page in notepad. It should say something like:
      Image titled 610238 5b2
    • Save this as INST.txt in the folder of the batch file, then make it so that your game will print the text to the console on the instructions page:
      Image titled 610238 5b3
    • Run the program and make sure it works.
      Image titled 610238 5b4

    Work on the contents of the game itself. This is where most of your creativity/research, work, and time is spent working on the game, as well as where most of the game's scripting should be. There should be a place that you go when you get an answer wrong, and a way to advance to the next question when you get the answer right. The above will have basic questions about the exterior of a car. You may replace them with what you like.
    • Run the program and make sure it works.

    Create a winning screen. Creating a winning screen is as simple as the instructions screen. Create a text document with praise for winning and save it as WIN.txt in the batch folder. Add the following lines to the end of your game for the winning screen:

    Your game should now look like the code above:
    • Run the program and make sure it works.
  9. Image titled 610238 9 1
    Touch up your file. Start by going to each label and placing the cls command after it. This will clear the screen at each label so you don't have a screen full of unnecessary information.

    Correct grammar where appropriate. If you want, make all of the answers on the list complete sentences. NOTE THAT YOU SHOULD AVOID CONTRACTIONS IN THE BATCH SCRIPT ECHO COMMAND! You should also avoid slashes and greater than/less than symbols, stars, percent symbols, and any other unusual symbols. These symbols will create a syntax error that causes the program to stop, lag, or crash.
  11. Image titled 610238 11 1
    Create graphics for the game if you would like. Generate ASCII art in separate text documents and use the type command to display them in the program:
  12. Image titled 610238 12 1
    Correct any typing errors that you can find. Think of your own things to correct. Then add your color with the color command. It is suggested that you place it at the beginning of the program so that the whole program is of this color. Here is the explanation of how to use it directly from the command line:

    Sets the default console foreground and background colors.

    COLOR [attr]

    attr Specifies color attribute of console output

    Color attributes are specified by TWO hex digits -- the first corresponds to the background; the second the foreground. Each digit can be any of the following values:

    0 = Black 8 = Gray 1 = Blue 9 = Light Blue 2 = Green A = Light Green 3 = Aqua B = Light Aqua 4 = Red C = Light Red 5 = Purple D = Light Purple 6 = Yellow E = Light Yellow 7 = White F = Bright White

    If no argument is given, this command restores the color to what it was when CMD.EXE started. This value either comes from the current console window, the /T command line switch or from the Default Color registry value.

    • In other words, if you wanted a bright white background and black text:

       @echo off color f0 :MAIN cls echo.

    Congratulations, you have just created a basic computer game with batch script!


  • If you want to save something as a batch file but don't want to finish it just yet, you can edit the file again by right-clicking and selecting "Edit".
  • Batch is a fun way to start writing programs. To move onto something just a tiny bit harder but much more powerful try the python programming language.

You can find free videos on youtube to learn any programming language.

  • When saving, make sure you to change the drop down menu under the file name input box from "text (txt) document" to "All files". After doing that, ensure that your file name always ends with .bat.
  • Save frequently. You may regret it if you don't.
  • If you have got multiple programs that work hand in hand, you can use the "call" command to start a different batch file from within the one you're running.
  • Try creating many versions of the game as you go so you can compare them and see if there are any errors. Don't worry about how much space it will take, batch files are very small.
  • You can set variable by putting "set variable name=value", or you can get users to set variables by putting "set /p input=Input text:". "Input text" can be replaced with anything you want them to see when setting this variable.


  • NEVER put any MS DOS commands in the echo command, as they will be carried out. Remember that everything displayed by the command line is an echo!
  • NEVER put any MS DOS commands in the text files that are typed out to the console. Text files solve some problems, such as the slashes and stars, but commands in them will still be carried out by the system.
  • It is often times said that it is illegal to send batch files over the internet. By no means is this true, but be aware of the fact that you may get in trouble for sending dangerous batch files over the internet(e.g.: batch files that crash the computer, delete vital system files, etc...). They are not called viruses, but they are still harmful and you can get in serious trouble for them.
  • Be wary of the "del" command. Although it can be used to delete, for example, users for a longer game, it is unrestricted and can be used to delete anything, including vital files. NEVER use this command until you really know what you're doing with it.
