Mind Snake - Game

This is a simple Snake game created using Processing core and Java. It was created as part of my experiment to see how much can be done in one night and this is the result. The development took few days actually but core of the game, music, graphics and design was done in one night, everything else was just polishing and making game stable. I hope you will enjoy. If you want to download the project and work on it, please read Development Note bellow.

About development

As already said, game was developed using Processing core libraries and Java inside Eclipse IDE. Since Processing is not developed to be used for creating complex GUIs, this project turned out to be very complex and complicated but at the same time very interesting. First of all project started with a blank page, therefore first step was to create typical components like buttons, input fields, layout managers and so on. Next step was to create game area and game mechanics. I decided to divide game area into grid and create tick engine that will move snake in the game area and apply game rules. After this was done, I created system that will manage user profiles and scoring system that will keep track of all games that user have played, best score, play time and so one. With this done, only thing left was to make music and sound effects and to design elements to look decent. In my blog I will go into detail about game development.

How to play

Here is a short video showing you how to use the game.

Download Executable

To run game on you computer you will need to download an executable from Dropbox and then follow steps bellow for your system. Please make sure to run and use only JARs provided on this github page!

Windows

  • Download and install Oracle Java 8.
  • To confirm that installation was successful open cmd and type: java -version. System should respond with something like this:
    java version "1.8.0_191"
    Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
    Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)
  • After this unpack the .zip downloaded from Dropbox and double click on the app_windows.bat or mind-snake.jar.
  • If previous step did not work, open cmd or PowerShell and move to directory where you have unpacked the ZIP file.
cd /path/to/mind-snake/
  • In here, run the following command: java -jar mind-snake.jar

Linux

  • Go to Oracle website and follow the instructions.
  • Now add installed JRE as JAVA_HOME.
  • Go to profile vim /etc/profile, add next lines and save file.
    # Change _USER_ to your system user.
    export JAVA_HOME="/home/_USER_/path/to/jdk"
    export PATH=$JAVA_HOME/bin:$PATH
  • Reboot you system. After this, if you execute the command java -version system will echo Java version installed.
    java version "1.8.0_191"
    Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
    Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)
  • After this unpack the .zip downloaded from Dropbox to Documents and try to double click on app_linux.
  • If this does not work, open terminal and run:
    # Change _USER_ to your Linux user.
    cd /home/_USER_/Documents/mind-snake/
    java -jar mind-snake.jar

MAC

  • Download and install JDK 8.
  • To confirm that installation was successful open terminal and type: java -version. System should respond with something like this:
    java version "1.8.0_191"
    Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
    Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)
  • After this unpack the .zip downloaded from Dropbox to Documents and try to double click on app_mac. System will tell you that application is from unknown source.
  • If this does not work, open terminal and run:
    # Change _USER_ to your MAC user.
    cd /Users/_USER_/Documents/mind-snake/
    java -jar mind-snake.jar

Note

  • Application was tested using JDK 11 and it is working with some warnings with BASE64 deprecated.
  • users.collection and scores.collection are used for storing data and they are encrypted using AES128 with random KEY and VECTOR. They are stored in application JAR as a static value, therefore they are not safe since decompiling JAR will reveal there values.
  • 2018-09 Eclipse release was used for this project.
