Key technical points

Customized translucent JPanel

Class definition rewritten

@Override
	protected void paintComponent(Graphics g){
		super.paintComponent(g);
		
			Graphics2D graphics2d = (Graphics2D) g.create();
			
			graphics2d.setComposite(AlphaComposite.SrcOver.derive(transparency));
			
			
			graphics2d.setColor(getBackground());
			graphics2d.fillRect(0, 0, getWidth(), getHeight());
			
//			graphics2d.drawImage(background, 0, 0, getWidth(), getHeight(), 46, 114, 315, 521, this);

Collision realization

private boolean isCollide(Ball firstBall, Ball secondBall) {
	int xDistance = Math.abs(firstBall.getX() - secondBall.getX());
	int yDistance = Math.abs(firstBall.getY() - secondBall.getY());
	return xDistance<=max(firstBall.getLifesecond(),secondBall.getLifesecond())
			&& yDistance<=firstBall.getLifesecond() && yDistance<=secondBall.getLifesecond();
}

Introduction of key functions

Duck class

Which is the duck class

variable

It declares various parameters of the duck, including but not limited to

• x、y（x, y axis position）
• lifesecond（Health value / picture width and height）
• duckpicture（url）

method

• drawBall（Draw the function of the duck）
• changeDirection（Change direction after hitting the wall）

public void changeDirection() {
		int randomSpeed= speedRandom.getRandom();
		if(x>=GWIDTH-lifesecond) {
			xSpeed = -randomSpeed;
		}
		else
		if(x<=0) {
			xSpeed = randomSpeed;
		}
		if(y>=GHEIGHT-lifesecond-50) {
			ySpeed = -randomSpeed;
		}
		else
		if(y<=0) {	
			ySpeed =  randomSpeed;
		}
	}

• move(Duck movement function)

public void move() {
		x+=xSpeed;
		y+=ySpeed;
	}

• getter and setter

Board class

The pond drawing board class is also the most important class of the entire project, where most of the threads are implemented

UML

@w=600

variable

• playduckmusic（Control music playback）
• MAX_BALLS（Maximum number of ducks）
• MAX_Lilies（Number of water lilies）
• ArrayList balls（Loading ducks）
• ArrayList lilies（Mount water lily）

method

loadballs

private void loadBalls() {

		balls.add(new Ball());

}

Thread

• Music thread
• Detect collision threads
• Detect lead duck thread
• Load water lily thread
• Load duck thread

GameFrame

UML

@w=600

main

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		InitGlobalFont(new Font("宋体", Font.PLAIN, 48));  //统一设置字体

		GameFrame frame = new GameFrame();



		System.out.println(Thread.currentThread());


	}

Setting

UML

interface

Have buttons and text boxes

 private void windowInit() {
        this.setTitle("设置");
        this.setSize(1500,1500);
        this.setLocationRelativeTo(null);

        JPanel panel = new JPanel();

        placeTextField.setBounds(300,300,300,100);
        panel.add(placeTextField);
        JButton addPlaceButton = new JButton("设置最大鸭子个数");
        addPlaceButton.setBounds(650,300,500,100);
        panel.add(addPlaceButton);


        JTextField placeTextField2 = new JTextField(10);

        addPlaceButton2.setBounds(650,600,500,100);
        panel.add(addPlaceButton2);


        JButton addPlaceButton4 = new JButton("未静音(Not mute)");
        addPlaceButton4.setBounds(450,900,600,100);
        panel.add(addPlaceButton4);

        addPlaceButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent ee) {

            }
        });
        addPlaceButton2.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                registerAddPlaceButtonEvent2(placeTextField2);
                Board.MAX_Lilies = Integer.parseInt(placeTextField2.getText());
            }
        });
        addPlaceButton4.addActionListener(new ActionListener() {

                Board.playmusic=Board.playmusic*-1;
                if(Board.playmusic==-1){
                addPlaceButton4.setText("已静音(Mute)");
            }
                else {
                    addPlaceButton4.setText("未静音(Not mute)");
                }
            }
        });
        this.getContentPane().add(panel);
