Introduction




Java is one of the most widely used programming languages in the world. It is an object-oriented language that allows you to create applications that can run on different operating systems, such as Windows, Linux, or Mac OS. One of the applications that you can create with Java is a video game. A video game is a software program that provides interactive entertainment by simulating a virtual world, where the user can control characters, objects, or events.


There are many types of video games, such as action, adventure, puzzle, strategy, simulation, or role-playing. Some video games are designed for specific devices, such as consoles, handhelds, or smartphones. Others are designed for cross-platform compatibility, meaning that they can run on any device that supports Java. These are called video player java games.


To play video player java games on your device, you need to download and install them first. You can find many free or paid java games online, on websites like [Java Games](^1^) or [Java Game Download](^2^). To download a java game, you need to click on the download link or button, and save the file on your device. The file will have a .jar extension, which stands for Java Archive. A .jar file is a compressed file that contains all the files and resources needed for the game.


To install a java game on your device, you need to have a Java Runtime Environment (JRE) installed. A JRE is a software package that provides the necessary components for running Java applications. You can download the latest version of JRE from [Oracle](^3^). To install a java game on your computer, you need to double-click on the .jar file and follow the instructions. To install a java game on your mobile device, you need to transfer the .jar file from your computer to your device via USB cable or Bluetooth connection. Then you need to open the file manager app on your device and locate the .jar file. Tap on it and follow the instructions.


How to Make a Video Game in Java (2D Basics)




If you want to create your own video player java game, you need to have some basic knowledge of Java programming and 2D graphics. In this section, you will learn how to use the Java Swing library for 2D graphics, how to use the starter code from GitHub, and how to add your own features and ideas to the game.


What you need to get started




To make a video game in Java, you need to have two things: a Java Development Kit (JDK) and an Integrated Development Environment (IDE). A JDK is a software package that contains the tools and libraries for developing and running Java applications. An IDE is a software application that provides a user-friendly interface for writing, editing, debugging, and testing code. You can download the latest version of JDK from [Oracle]. You can choose any IDE that supports Java, such as Eclipse, NetBeans, or IntelliJ IDEA.


You also need to have a basic understanding of Java syntax and object-oriented programming. Java syntax is the set of rules and conventions that define how to write Java code. Object-oriented programming is a programming paradigm that organizes data and behavior into classes and objects. A class is a blueprint that defines the attributes and methods of a type of object. An object is an instance of a class that has specific values and behaviors. For example, you can create a class called Player that defines the attributes and methods of a player object, such as name, score, move, or shoot.

How to use the Java Swing library for 2D graphics




Java Swing is a library that provides a set of components for creating graphical user interfaces (GUIs) in Java. It also provides a subpackage called javax.swing.graphics2D that contains classes and methods for drawing 2D graphics on the screen. To use the Java Swing library for 2D graphics, you need to create three main components: a JFrame, a JPanel, and a JLabel.


A JFrame is a window that contains the GUI components of your application. It has a title bar, a menu bar, a content pane, and other optional features. To create a JFrame, you need to import the javax.swing.JFrame class and create an object of it. You also need to set some properties of the JFrame, such as its size, location, title, visibility, and default close operation. For example:



import javax.swing.JFrame; public class GameFrame extends JFrame public GameFrame() //set the size of the frame setSize(800, 600); //set the location of the frame on the screen setLocation(100, 100); //set the title of the frame setTitle("Video Player Java Game"); //make the frame visible setVisible(true); //set the default close operation setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);


A JPanel is a container that holds other GUI components. It can also be used as a canvas for drawing 2D graphics. To create a JPanel, you need to import the javax.swing.JPanel class and create an object of it. You also need to override the paintComponent method of the JPanel class, which is called whenever the panel needs to be repainted. In this method, you can use the Graphics object that is passed as a parameter to draw shapes, images, and text on the panel. For example:



import javax.swing.JPanel; import java.awt.Graphics; import java.awt.Color; public class GamePanel extends JPanel @Override public void paintComponent(Graphics g) //call the superclass method super.paintComponent(g); //set the background color setBackground(Color.BLACK); //set the drawing color g.setColor(Color.WHITE); //draw a rectangle g.fillRect(100, 100, 200, 100); //draw an image g.drawImage(image, 400, 100, null); //draw some text g.drawString("Hello World", 300, 300);


A JLabel is a component that displays text or an image on the screen. It can also be used as a timer or a score board for your game. To create a JLabel, you need to import the javax.swing.JLabel class and create an object of it. You also need to set some properties of the JLabel, such as its text, font, color, alignment, and location. For example:



import javax.swing.JLabel; import java.awt.Font; import java.awt.Color; public class GameLabel extends JLabel public GameLabel() //set the text of the label setText("Time: 00:00"); //set the font of the label setFont(new Font("Arial ", Font.BOLD, 20)); //set the color of the label setForeground(Color.WHITE); //set the horizontal alignment of the label setHorizontalAlignment(JLabel.CENTER); //set the location of the label on the panel setBounds(300, 50, 200, 50);


To add these components to your game, you need to create an object of each class and add them to the JFrame. You also need to set the layout manager of the JFrame to null, so that you can position the components manually. For example:



public class Game public static void main(String[] args) //create a frame object GameFrame frame = new GameFrame(); //set the layout manager to null frame.setLayout(null); //create a panel object GamePanel panel = new GamePanel(); //add the panel to the frame frame.add(panel); //create a label object GameLabel label = new GameLabel(); //add the label to the panel panel.add(label);


How to use the starter code from GitHub




If you want to save some time and effort, you can use the starter code from GitHub that provides a basic template for a video player java game. The starter code contains four classes: Game, GameFrame, GamePanel, and GameLabel. It also contains an image file called player.png that represents the player character in the game. You can download the starter code from [GitHub] and run it on your IDE.


The starter code creates a simple game where you can move a player image around the screen using the arrow keys. It also displays a timer and a score on the top of the screen. The timer counts down from 60 seconds and the score increases by one every time you move. The game ends when the timer reaches zero or when you close the window.


To understand how the starter code works, you need to look at each class and see what it does. The Game class is the main class that creates and runs the game. It contains a main method that creates a frame object and sets its layout manager to null. It also creates a panel object and adds it to the frame. It then creates a label object and adds it to the panel. It also creates a thread object that runs the game loop. The game loop is a while loop that updates and renders the game state every 10 milliseconds.



public class Game implements Runnable //declare some constants public static final int WIDTH = 800; public static final int HEIGHT = 600; public static final int DELAY = 10; //declare some variables private GameFrame frame; private GamePanel panel; private GameLabel label; private Thread thread; private boolean running; public Game() //create a frame object frame = new GameFrame(); //set the layout manager to null frame.setLayout(null); //create a panel object panel = new GamePanel(); //add the panel to the frame frame.add(panel); //create a label object label = new GameLabel(); //add the label to the panel panel.add(label); //create a thread object thread = new Thread(this); //set running to true running = true; public void start() //start the thread thread.start(); public void run() //run the game loop while (running) //update the game state update(); //render the game state render(); //sleep for some time try Thread.sleep(DELAY); catch (InterruptedException e) e.printStackTrace(); public void update() //update the panel panel.update(); //update the label label.update(); public void render() //repaint the panel panel.repaint(); public static void main(String[] args) //create a game object Game game = new Game(); //start the game game.start();


The GameFrame class is a subclass of JFrame that creates a window for the game. It sets the size, location, title, visibility, and default close operation of the window. It also implements the KeyListener interface, which allows it to handle keyboard input from the user. It overrides the keyPressed and keyReleased methods, which are called when a key is pressed or released. In these methods, it sets the values of four boolean variables: up, down, left, and right. These variables indicate which direction the player is moving in. For example:



public class GameFrame extends JFrame implements KeyListener //declare some variables private boolean up; private boolean down; private boolean left; private boolean right; public GameFrame() //set the size of the frame setSize(Game.WIDTH, Game.HEIGHT); //set the location of the frame on the screen setLocation(100, 100); //set the title of the frame setTitle("Video Player Java Game"); //make the frame visible setVisible(true); //set the default close operation setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //add a key listener to the frame addKeyListener(this); public void keyPressed(KeyEvent e) //get the key code of the pressed key int keyCode = e.getKeyCode(); //check which key is pressed and set the corresponding variable to true if (keyCode == KeyEvent.VK_UP) up = true; if (keyCode == KeyEvent.VK_DOWN) down = true; if (keyCode == KeyEvent.VK_LEFT) left = true; if (keyCode == KeyEvent.VK_RIGHT) right = true; public void keyReleased(KeyEvent e) //get the key code of the released key int keyCode = e.getKeyCode(); //check which key is released and set the corresponding variable to false if (keyCode == KeyEvent.VK_UP) up = false; if (keyCode == KeyEvent.VK_DOWN) down = false; if (keyCode == KeyEvent.VK_LEFT) left = false; if (keyCode == KeyEvent.VK_RIGHT) right = false; public void keyTyped(KeyEvent e) //do nothing //getters for the variables public boolean isUp() return up; public boolean isDown() return down; public boolean isLeft() return left; public boolean isRight() return right;


The GamePanel class is a subclass of JPanel that creates a canvas for drawing 2D graphics. It overrides the paintComponent method, which is called whenever the panel needs to be repainted. In this method, it uses the Graphics object that is passed as a parameter to draw the background, the player, and the score on the panel. It also has an update method, which is called by the game loop to update the game state. In this method, it updates the position of the player based on the values of the boolean variables from the frame object. It also updates the score based on the number of moves. It also checks if the game is over based on the value of the timer from the label object. For example:



public class GamePanel extends JPanel //declare some constants public static final int PLAYER_WIDTH = 50; public static final int PLAYER_HEIGHT = 50; public static final int PLAYER_SPEED = 5; //declare some variables private GameFrame frame; private GameLabel label; private Image player; private int playerX; private int playerY; private int score; public GamePanel() //create a frame object frame = new GameFrame(); //create a label object label = new GameLabel(); //load the player image from the file player = new ImageIcon("player.png").getImage(); //set the initial position of the player playerX = (Game.WIDTH - PLAYER_WIDTH) / 2; playerY = (Game.HEIGHT - PLAYER_HEIGHT) / 2; //set the initial score to zero score = 0; @Override public void paintComponent(Graphics g) //call the superclass method super.paintComponent(g); //set the background color setBackground(Color.BLACK); //draw the player image g.drawImage(player, playerX, playerY, PLAYER_WIDTH, PLAYER_HEIGHT, null); //draw the score g.setColor(Color.WHITE); g.setFont(new Font("Arial", Font.BOLD, 20)); g.drawString("Score: " + score, 10, 30); public void update() //update the position of the player based on the keyboard input if (frame.isUp() && playerY > 0) playerY -= PLAYER_SPEED; score++; if (frame.isDown() && playerY 0) playerX -= PLAYER_SPEED; score++; if (frame.isRight() && playerX


The GameLabel class is a subclass of JLabel that displays the timer and the score on the screen. It has two variables: time and score. It also has a constructor that sets the text, font, color, alignment, and location of the label. It also has an update method, which is called by the game loop to update the label text. In this method, it decreases the time by one every second and updates the text with the new time and score. For example:



public class GameLabel extends JLabel //declare some constants public static final int TIME = 60; public static final int WIDTH = 200; public static final int HEIGHT = 50; //declare some variables private int time; private int score; public GameLabel() //set the initial time and score time = TIME; score = 0; //set the text of the label setText("Time: " + time + " Score: " + score); //set the font of the label setFont(new Font("Arial", Font.BOLD, 20)); //set the color of the label setForeground(Color.WHITE); //set the horizontal alignment of the label setHorizontalAlignment(JLabel.CENTER); //set the location of the label on the panel setBounds((Game.WIDTH - WIDTH) / 2, 10, WIDTH, HEIGHT); public void update() //decrease the time by one every second if (System.currentTimeMillis() % 1000 == 0) time--; //update the text of the label with the new time and score setText("Time: " + time + " Score: " + score); //getters and setters for the variables public int getTime() return time; public int getScore() return score; public void setScore(int score) this.score = score;


To modify the starter code, you can change some of the constants or variables, such as the size, speed, or image of the player. You can also add some new features or ideas to the game, such as enemies, obstacles, power-ups, sound effects, or levels. You can use your creativity and imagination to make your game more fun and challenging.


How to Play MP4 Video Files in a JFrame




If you want to play MP4 video files in your video player java game, you need to use a third-party library or framework that supports MP4 format. The reason is that MP4 is a newer and more complex format than older formats like AVI or MPEG. It uses advanced compression and encoding techniques to reduce file size and improve quality. However, these techniques also make it harder to decode and play MP4 files in Java.


The Java Media Framework (JMF) is a library that provides classes and methods for playing media files in Java. However, JMF is an outdated and discontinued library that has not been updated since 2004. It does not support MP4 format natively, and it requires additional plug-ins or codecs to play MP4 files. Moreover, JMF has many compatibility and performance issues with modern operating systems and devices.


Therefore, it is better to use a third-party library or framework that supports MP4 format natively and provides better functionality and performance than JMF. Some examples of such libraries or frameworks are VLCJ, Xuggler, or JavaFX Media.


How to use VLCJ to play MP4 files in Java




VLCJ is a library that allows you to use VLC media player in Java. VLC media player is a free and open-source software that can play almost any media file format. VLCJ provides a wrapper for VLC's native library (libvlc) and exposes its functionality through Java classes and methods. To use VLCJ to play MP4 files in Java, you need to do the following steps:


  • Download and install VLC media player from [VLC]. Make sure you install it in a location that does not contain spaces or special characters.



  • Download and add VLCJ library to your project from [VLCJ]. You can use Maven or Gradle to manage your dependencies.



Create a media player component and add it to your JFrame. A media player component is a component that can play media files using VLC. To create a media player component, you need to import the uk.co.caprica.vlcj.player.component.EmbeddedMediaPlayerComponent class and create an object of it. You also need to add the component to your JFrame using the add method. For example:



import uk.co.caprica.vlcj.player.component.EmbeddedMediaPlayerComponent; public class VideoPlayer extends JFrame //declare a media player component private EmbeddedMediaPlayerComponent mediaPlayerComponent; public VideoPlayer() //create a media player component mediaPlayerComponent = new EmbeddedMediaPlayerComponent(); //add the component to the frame add(mediaPlayerComponent);


Play the MP4 file using the media player component. To play the MP4 file, you need to get the media player object from the component using the mediaPlayer method. You also need to specify the path of the MP4 file using the playMedia method. For example:



public class VideoPlayer extends JFrame //declare a media player component private EmbeddedMediaPlayerComponent mediaPlayerComponent; public VideoPlayer() //create a media player component mediaPlayerComponent = new EmbeddedMediaPlayerComponent(); //add the component to the frame add(mediaPlayerComponent); public void playVideo(String path) //get the media player object from the component EmbeddedMediaPlayer mediaPlayer = mediaPlayerComponent.mediaPlayer(); //play the MP4 file using the path mediaPlayer.playMedia(path);


  • Enjoy your video player java game with MP4 files.
