java多线程捕鱼达人小游戏

1.创建弹窗，并设置窗口属性。

2.创建Pool类，继承JPanel类，并重写paint方法。

3.创建Net类，

4.创建Fish类，继承Thread类，重写run方法。

5.刚开始先画一条鱼，一个动作，然后利用数组，定义多条鱼，在水里游起来，最后定义catchFish方法，捕鱼。

import javax.swing.*;public class FishGame {public static void main(String[] args) {//创建窗口JFrame jFrame = new JFrame();//创建一个Pool对象,并把该对象放到窗口上Pool pool = new Pool();jFrame.add(pool);//设置大小(窗口大小由池塘图片大小决定）jFrame.setSize(800,480);//设置居中jFrame.setLocationRelativeTo(null);//设置大小不可变jFrame.setResizable(false);//设置关闭窗口退出程序jFrame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);//展示窗口jFrame.setVisible(true);}
}

import javax.imageio.ImageIO;
import javax.swing.*;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;//继承JPanel类
public class Pool extends JPanel {//声明池塘图片BufferedImage poolImage;//声明池塘的宽和高，XY坐标int poolWidth = 0;int poolHeight = 0;int poolX = 0;int poolY = 0;//定义一个构造方法Pool(){try {//接收读取到的池塘图片,宽和高poolImage = ImageIO.read(new File("src/images/bg.jpg"));poolWidth = poolImage.getWidth();poolHeight = poolImage.getHeight();} catch (IOException e) {e.printStackTrace();}}//重写父类paint方法@Overridepublic void paint(Graphics g) {g.drawImage(poolImage,0,0,null);}
}

运行结果如下

import javax.swing.*;public class FishGame {public static void main(String[] args) {//创建窗口JFrame jFrame = new JFrame();//创建一个Pool对象,并把该对象放到窗口上Pool pool = new Pool();jFrame.add(pool);//设置大小(窗口大小由池塘图片大小决定）jFrame.setSize(800,480);//设置居中jFrame.setLocationRelativeTo(null);//设置大小不可变jFrame.setResizable(false);//设置关闭窗口退出程序jFrame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);//展示窗口jFrame.setVisible(true);//启动鼠标监听事件pool.action();}
}

}

import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;public class Net {//声明渔网图片，和渔网的长宽和XY坐标BufferedImage netImage;int netWidth = 0;int netHeight = 0;int netX = 0;int netY = 0;//创建无参构造方法Net(){try {//接收渔网图片,渔网的宽和高netImage = ImageIO.read(new File("src/images/net09.png"));netWidth = netImage.getWidth();netHeight = netImage.getHeight();} catch (IOException e) {e.printStackTrace();}}
}

运行效果，渔网可以跟着鼠标移动

import javax.swing.*;public class FishGame {public static void main(String[] args) {//创建窗口JFrame jFrame = new JFrame();//创建一个Pool对象,并把该对象放到窗口上Pool pool = new Pool();jFrame.add(pool);//设置大小(窗口大小由池塘图片大小决定）jFrame.setSize(800,480);//设置居中jFrame.setLocationRelativeTo(null);//设置大小不可变jFrame.setResizable(false);//设置关闭窗口退出程序jFrame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);//展示窗口jFrame.setVisible(true);//启动鼠标监听事件pool.action();}

}

运行结果如下：鼠标点击鱼即可捕捉，被捕捉的鱼返回起点重新游
