Popcat - Java

Popcat is a simple clicking game that originally gained popularity in Taiwan. It requires the player to click on the cat as many times as possible within a given time period.

In this project, we will create a Popcat game using Java programming language.

Getting Started

To get started, make sure that you have install JDK (Java Development Kit) on your computer. You can download it from Oracle's website.

You will also need an IDE (Integrated Development Environment) such as Eclipse or NetBeans.

Creating the Popcat Game

Step 1: Setting up the project

Open up your IDE and create a new Java project. Name the project “PopCat” and create a new package named "popcat".

Step 2: Creating the Game Window

Create a new class named "PopCatGame" in the "popcat" package. This class will contain all the game logic and the main game window.

Add the following code to create the game window:

package popcat;

import javax.swing.JFrame;

public class PopCatGame extends JFrame {

    public PopCatGame() {
        setTitle("PopCat");
        setSize(500, 500);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        setResizable(false);
        setVisible(true);
    }

    public static void main(String[] args) {
        new PopCatGame();
    }
}

Step 3: Adding the Cat Image

Download the image of the cat and save it to the project directory. You can download the cat image from here.

In the "popcat" package, create a new class named "Cat". Add the following code to this class:

package popcat;

import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;

import javax.swing.JPanel;

public class Cat extends JPanel {

    private Image catImage;

    public Cat() {
        catImage = Toolkit.getDefaultToolkit().getImage("cat.png");
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.drawImage(catImage, 0, 0, null);
    }
}

Step 4: Adding Clicking Functionality

Add the following code to the "PopCatGame" class to add clicking functionality:

public class PopCatGame extends JFrame implements MouseListener {

    private int score;
    private JLabel scoreLabel;
    private Cat cat;
    private Timer timer;

    public PopCatGame() {
        // ...

        score = 0;

        scoreLabel = new JLabel("Score: 0");
        scoreLabel.setFont(new Font(Font.DIALOG, Font.BOLD, 20));
        scoreLabel.setForeground(Color.WHITE);
        scoreLabel.setBounds(10, 10, 150, 30);
        add(scoreLabel);

        cat = new Cat();
        cat.setBounds(150, 150, 200, 200);
        cat.addMouseListener(this);
        add(cat);

        timer = new Timer(1000, new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                scoreLabel.setText("Score: " + score);
                score = 0;
            }
        });
        timer.start();
    }

    @Override
    public void mouseClicked(MouseEvent e) {
        if (e.getSource() == cat) {
            score++;
        }
    }

    // ...

}

Step 5: Running the Game

Run the “PopCatGame” class to start the game. You should see a window with the cat image and a score label.

Conclusion

In this project, we learned how to create a Popcat game using Java programming language. We created a game window, added the cat image, and implemented clicking functionality to calculate the score.

This is a simple example, but it demonstrates how Java can be used to create games and interactive applications.
