测试类：

package game;import java.awt.image.BufferedImage;import java.io.File;import java.io.IOException;import javax.imageio.ImageIO;import javax.swing.JFrame;/** * 测试类 * @author Lenovo * */public class Client { public static void main(String[] args) throws IOException { //创建窗口 JFrame gameFrame = new JFrame("捕鱼达人");  //将池塘放入到界面中去 Pool pool = new Pool(); gameFrame.setContentPane(pool);  //创建窗口图标,绝对路径 BufferedImage icon = ImageIO.read(new File("E:/New_life/fish_game/resource/images/fish07_03.png")); gameFrame.setIconImage(icon); //设置窗口的尺寸 gameFrame.setSize(800, 500); //窗口的位置 gameFrame.setLocation(10, 10); //设置窗口不可拖拽 gameFrame.setResizable(false); //设置窗口可以关闭 gameFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //让窗口显示 gameFrame.setVisible(true);  //调用方法 pool.action(); }}

大炮的设置：

与鱼塘的设置：

鱼类的设置：

package game;import java.awt.image.BufferedImage;import java.io.File;import java.io.IOException;import java.util.Random;import javax.imageio.ImageIO;public class Fish extends Thread{  //宽度 @SuppressWarnings("unused") private int width; @SuppressWarnings("unused") private int height; //位置 //x坐标 @SuppressWarnings("unused") private int x; //y坐标 @SuppressWarnings("unused") private int y; //图片 @SuppressWarnings("unused") private BufferedImage image; //速度 @SuppressWarnings("unused") private int step; //是否被抓 @SuppressWarnings("unused") private boolean isCatch;  //鱼游动的图片数组 @SuppressWarnings("unused") private BufferedImage[] images; //抓获鱼的图片 private BufferedImage[] catchImages; //图片的下标 @SuppressWarnings("unused") private int imagesIndex;  /** *鱼的构造方法 * @param name 鱼的图片名称 * @throws IOException  */ public Fish(String imageName) throws IOException { //鱼游动的初始化 this.images = new BufferedImage[10];  for (int i = 0; i < 10; i++) {  String fishName = imageName + "_0" + i + ".png";  BufferedImage tempImage = ImageIO.read(new File("resource/images/" + fishName));  images[i] = tempImage; }  //初始化图片下标 this.imagesIndex = 0; this.image = this.images[this.imagesIndex];  //初始化鱼的宽度和高度 this.width = this.image.getWidth(); this.height = this.image.getHeight();  //初始化x和y的坐标 this.x = 800; Random random = new Random(); int nextInt = random.nextInt(400); this.y = nextInt;  //初始化速度 this.step = random.nextInt(5);  //初始化是否被抓住 this.isCatch = false; this.catchImages = new BufferedImage[2]; this.catchImages[0] = ImageIO.read(new File("resource/images/" + imageName + "_catch_01.png")); // this.width = image.getWidth(); }  /** * 鱼的游动 */ public void move() { //坐标减去游动的速度 this.x = this.x - this.step;  //切换鱼的图片 this.image = this.images[this.imagesIndex ++ % this.images.length];  //重新游一遍,小于鱼与横坐标则返回 if (this.x < -this.width) {  //重置x坐标  this.x = 800;  //重置y坐标  Random random = new Random();  this.y = random.nextInt(375);  //重置鱼游的速度  this.step = random.nextInt(5) + 1; } //休眠 try {  sleep(50); } catch (InterruptedException e) {  // TODO Auto-generated catch block  e.printStackTrace(); } } /** * 被捕获时翻滚 */ public void turnOver() { //切换鱼被捕获时鱼的图片 for (int i = 0; i < 6; i++) {  this.image = this.catchImages[i % this.catchImages.length];  try {  sleep(50);  } catch (InterruptedException e) {  e.printStackTrace();  } } //重置鱼的属性,坐标，速度，是否被抓 this.x = 800; Random random = new Random(); this.y = random.nextInt(375); this.step = random.nextInt(5) + 1; this.isCatch = false; }   @Override public void run() { while (true) {  if (this.isCatch) {  turnOver();  }else {  move();   } }  } /** * 生成了鱼的属性set和get方法 * @return */ public int getWidth() { return width; } public void setWidth(int width) { this.width = width; } public int getHeight() { return height; } public void setHeight(int height) { this.height = height; } public int getX() { return x; } public void setX(int x) { this.x = x; } public int getY() { return y; } public void setY(int y) { this.y = y; } public BufferedImage getImage() { return image; } public void setImage(BufferedImage image) { this.image = image; } public boolean isCatch() { return isCatch; } public void setCatch(boolean isCatch) { this.isCatch = isCatch; }}

鱼网的设置（这里渔网是静态的，有缺陷）：

package game;/** * 捕鱼网 * @author Lenovo * */import java.awt.image.BufferedImage;import java.io.File;import java.io.IOException;import javax.imageio.ImageIO;public class Net { //图片 private BufferedImage image; //X坐标 private double x; //Y坐标 private double y; //宽度 private double width; //高度 private double height; //是否展示 private boolean isShow; /** * 渔网构造方法 * @throws IOException  */ public Net() throws IOException { //初始化图片 this.image = ImageIO.read(new File("resource/images/net09.png")); this.x = 100; this.y = 100; this.width = this.image.getWidth(); this.height = this.image.getHeight(); this.isShow = true;   } /** * 渔网的移动 * @param mouseX * @param mouseY */ public void move(double mouseX, double mouseY) { //求渔网的中心点 double centerX = this.x + this.width/2; double centerY = this.y + this.height/2;  //中心点与离鼠标的x位置 double xx = mouseX - centerX; //中心点与离鼠标的y位置 double yy = mouseY - centerY;  //左上角点平移 this.x = this.x + xx; this.y = this.y + yy;   } public BufferedImage getImage() { return image; } public void setImage(BufferedImage image) { this.image = image; } public double getX() { return x; } public void setX(double x) { this.x = x; } public double getY() { return y; } public void setY(double y) { this.y = y; } public double getWidth() { return width; } public void setWidth(double width) { this.width = width; } public double getHeight() { return height; } public void setHeight(double height) { this.height = height; } public boolean isShow() { return isShow; } public void setShow(boolean isShow) { this.isShow = isShow; }}

发射的子弹

package game;import java.awt.Point;import java.awt.image.BufferedImage;import java.io.File;import java.io.IOException;import javax.imageio.ImageIO;/** * 发射的子弹 * @author zouzhuo * */public class Bullet extends Thread{ //图片 private BufferedImage image; //坐标值 private int x; private int y; //大小 private int width; private int height; //是否活着 private boolean isAlive; //速度 private int step; //角度 private double thread; //子弹发射的原点 private Point point; //池塘 private Pool pool;  public Bullet(int x, int y, Double thread, Pool pool) throws IOException { this.image = ImageIO.read(new File("resource/images/bullet1.png")); this.width = this.image.getWidth(); this.height = this.image.getHeight(); this.isAlive = true; this.step = 10; this.x = x; this.y = y; this.thread = thread; this.point = new Point(x, y);// this.point.x = x;// this.point.y =y; this.pool = pool; } /** * 子弹移动的速度 */ public void move() { this.y = this.y - this.step;  //判断出界 int distance = this.point.y - this.y; //求xx,需要进一步进行强制转换 int xx = (int) (distance * Math.sin(this.thread)); int xxx = this.point.x + xx; //求yy坐标 int yy = (int) (distance * Math.cos(this.thread)); int yyy = this.point.y - yy; //判断是否出界 if (xxx < 0 || xxx > 800 || yyy < 0) {  //将子弹置为死亡  this.isAlive = false;  //在数组中删除子弹  this.pool.getBullets().remove(this); }  //判断是否击中鱼 Fish[] fishs = pool.getFishes(); for (Fish fish : fishs) {  //鱼的x坐标范围  int maxX = fish.getX() + fish.getWidth();  //鱼的y坐标范围  int mayY = fish.getY() + fish.getHeight();  if (xxx > fish.getX() && xxx < maxX && fish.getY() < yyy && yyy < mayY) {  //设置鱼被抓到  fish.setCatch(true);  //设置让子弹消失  this.isAlive = false;  //在数组中删除子弹  this.pool.getBullets().remove(this);  } } try {  sleep(50); } catch (InterruptedException e) {  // TODO Auto-generated catch block  e.printStackTrace(); }  } @Override public void run() { super.run(); while (true) {  //让子弹飞一会  if (isAlive) {  move();  }else {  //直接结束线程  return;  }   } } public BufferedImage getImage() { return image; } public void setImage(BufferedImage image) { this.image = image; } public int getX() { return x; } public void setX(int x) { this.x = x; } public int getY() { return y; } public void setY(int y) { this.y = y; } public int getWidth() { return width; } public void setWidth(int width) { this.width = width; } public int getHeight() { return height; } public void setHeight(int height) { this.height = height; } public double getThread() { return thread; } public void setThread(double thread) { this.thread = thread; } }

还有一个计分板没有写上，没有开始结束的界面，渔网是静态的，这些功能都还没有实现，日后更新。
