前言

游戏整体框架来着B站:这是链接:Java实战训练营在我的课设中改进了让鱼有游动特效，以及增添了鼠标监听事件等等游戏优化游戏效果: 在这里插入图片描述

1、创建FishFrame.java package FishGame; import javax.swing.*; import java.awt.event.*; /* * 步骤： * 1.先创建窗体对象 * 2.背景的绘制 * 3.键盘的监听事件 * 1.实现接口 * 2.添加监听的事件 * 4.将己方鱼放上去 * 5.让小鱼移动 * 6.敌方的🐟(先创建集合把鱼装起来，获取每个对象，画图） * 7.吃鱼 * 8.被吃 * 9.增加了鼠标事件 * */ public class FishFrame extends JFrame{ public FishFrame(String username){ setTitle("大鱼吃小鱼:欢迎你 "+username); FishPanel fishPanel=new FishPanel(username); add(fishPanel); addMouseMotionListener(new MouseMotionListener() { @Override public void mouseDragged(MouseEvent e) { } @Override public void mouseMoved(MouseEvent e) { fishPanel.move(e.getPoint()); } }); addKeyListener(new MyFishKeyListener(){ @Override public void keyPressed(KeyEvent e) { int vk=e.getKeyCode(); fishPanel.move(vk); } }); fishPanel.action();//启动线程 setBounds(100,20,1440,900); setVisible(true); setResizable(false); setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); addKeyListener(new MyFishKeyListener()); } public static void main(String[] args){ new FishFrame("用户"); } } class MyFishKeyListener implements KeyListener{ @Override public void keyTyped(KeyEvent e) { } @Override public void keyPressed(KeyEvent e) { } @Override public void keyReleased(KeyEvent e) { } } 2、创建FishPanel.java

里面的hit()鱼碰撞事件可以改进

package FishGame; import javax.swing.*; import java.awt.*; import java.util.ArrayList; import java.util.TimerTask; import java.util.Timer; import java.awt.event.KeyEvent; import java.awt.Graphics; public class FishPanel extends JPanel{ 标识状态0开始，1运行，2暂停，3是结束 public int state = START; public static final int START=0; public static final int RUNNING =1; public static final int PAUSE =2; public static final int GAMEOVER =3; Image bkImg = DataImg.background; Image start =DataImg.start; int score=0;//经验得分 ArrayList fishes = new ArrayList();//装其他🐟的集合 int fish_1=0,fish_2=1,fish_3=1,fish_4=1,fish_5=1; boolean lock=true; Point p; myFish fish; String username; public FishPanel(String username){ this.username=username; fish=new myFish(); } @Override public void paint(Graphics g) { super.paint(g); //绘制游戏背景界面 switch(state) { case START: g.drawImage(start, 0, 0, 1440, 900, null); g.setFont(new Font("微软雅黑",Font.BOLD,40)); g.setColor(Color.WHITE); g.drawString("按下空格开始",600,600); score=0;//再次初始化 break; case RUNNING: //背景绘制 drawBackGround(g); //绘制己方的小鱼 drawMyFish(g); //绘制其他的小鱼 drawFishes(g); //设置字体颜色 g.setColor(Color.white); Font f = new Font("黑体",Font.BOLD,20);//加粗 g.setFont(f); //传进去 g.drawString("当前得分:"+score, 15, 20);//在x=15,y=20显示分数 g.drawString("战斗力:"+fish.zhanli, 200, 20); break;//一样 case PAUSE: drawBackGround(g); drawMyFish(g); drawFishes(g); g.setColor(Color.white); Font fff = new Font("黑体",Font.BOLD,50); g.setFont(fff); g.drawString("按下空格继续游戏",500 ,450); break; case GAMEOVER: drawBackGround(g); drawMyFish(g); drawFishes(g); g.drawString("当前得分:"+score, 15, 20); g.setColor(Color.white); Font ff = new Font("黑体",Font.BOLD,50); g.setFont(ff); g.drawString("游戏结束",600 ,450); break; } } /*定时器、 1.生成其他鱼 2.移动*/ public void action(){//多线程,timer内部实现 Timer timer=new Timer(); timer.schedule(new TimerTask() {//定时器任务 @Override public void run() { if(state==1) { createFish();//1.创建其他鱼2.不断的改变其他鱼的位置： hitFish();//3.吃鱼 if(lock)move(p); outOfBounds();//4.当鱼跑出圈外，我们要删除集合中的鱼； repaint(); //重画 } } },20,10);//20延迟执行，10每隔10ms执行run里面的内容一次 } //产生鱼 private void createFish() { if((fish_1++%200)==0) {//每隔10ms自加一次 fishes.add(new Fish_1()); } if((fish_2++%300)==0) { fishes.add(new Fish_2()); fishes.add(new Fish_2_1()); } if((fish_3++%400)==0) { fishes.add(new Fish_3()); } if((fish_4++%600)==0) { fishes.add(new Fish_4()); } if((fish_5++%1500)==0) { fishes.add(new Fish_5()); } } private void hitFish() { for(int i=0;i if(fish.zhanli>=fishes.get(i).zhanli) { switch(fishes.get(i).zhanli) { case 1: score++; break; case 2: score+=2; break; case 3: score+=3; break; case 4: score+=4; break; } fishes.remove(i);//根据分数加战力 if(score>=10 && score=40 && score=80) fish.zhanli=4; }else { state=3;//运行结束 } } } } private void outOfBounds() { for(int i=0;i if(fishes.get(i).x+fishes.get(i).length fishes.remove(i); } } } //中心点在鱼的xy范围内,检测碰撞 public boolean hit(Fish fishs) { int x=(fish.x1+fish.x)/2,y=(fish.y+fish.y1)/2; int x1 = fish.x1,y1 = fish.y1; int x2 = fish.x,y2 = fish.y; if(((x>=fishs.x)&&(x=fishs.x)&&(x1=fishs.x)&&(x2 return true;//产生碰撞 } } return false; } public void move(int keycode) {//键盘事件移动鱼 switch(keycode) { case KeyEvent.VK_RIGHT: fish.moveRight(); break; case KeyEvent.VK_LEFT: fish.moveLeft(); break; case KeyEvent.VK_UP: fish.fishMoveUp(); break; case KeyEvent.VK_DOWN: fish.fishMoveDown(); break; case KeyEvent.VK_ESCAPE: if (state==RUNNING)state=GAMEOVER; break; case KeyEvent.VK_SPACE: if(state == 0) { state=RUNNING; }else if(state==1){ state=PAUSE; }else if(state==2){ state=RUNNING; } else if(state==3) { state=START; fish=new myFish(); fishes = new ArrayList(); } break; } repaint(); } public void move(Point point){ p=point; lock=true;//产生鼠标事件 if(p.x>(fish.x1+fish.x)/2 && p.y>=(fish.y1+fish.y)/2){fish.moveDownAndRight();} else if(p.x>(fish.x1+fish.x)/2 && p.yfish.moveDownAndLeft();} else if(p.xlock=false;} } //画其他鱼 private void drawFishes(Graphics g) { // TODO Auto-generated method stub for(int i=0;i // TODO Auto-generated method stub fish.draw(g); } private void drawBackGround(Graphics g) { // TODO Auto-generated method stub g.drawImage(bkImg, 0, 0, 1440, 900, 0, 0, 1920, 1080, null); } } 3. 创建一个DataImg.java来统一加载图片

注:游戏鱼的图片要采用游戏素材半透明的图片，截图会有框。

package FishGame; import javax.swing.*; import java.awt.*; import java.net.URL; public class DataImg { public static URL start_path = DataImg.class.getResource("Img/begin_picture.jpg"); public static URL fish08_path = DataImg.class.getResource("Img/fish08.png"); public static URL fish12_path = DataImg.class.getResource("Img/fish12.png"); public static URL fish03_path = DataImg.class.getResource("Img/fish03.png"); public static URL fish17_path = DataImg.class.getResource("Img/fish17.png"); public static URL background_path = DataImg.class.getResource("Img/background2.jpeg"); public static URL fish06_path = DataImg.class.getResource("Img/fish06.png"); public static URL lantern_path = DataImg.class.getResource("Img/fish.png"); public static Image start = new ImageIcon(start_path).getImage(); public static Image fish08 = new ImageIcon(fish08_path).getImage(); public static Image fish12 = new ImageIcon(fish12_path).getImage(); public static Image fish03 = new ImageIcon(fish03_path).getImage(); public static Image fish17 = new ImageIcon(fish17_path).getImage(); public static Image background = new ImageIcon(background_path).getImage(); public static Image fish06 = new ImageIcon(fish06_path).getImage(); public static Image lantern = new ImageIcon(lantern_path).getImage(); } 3.1 将图片保存在一个包下面如图:

在这里插入图片描述

4.创建鱼的类 4.1 鱼的父类Fish.java package FishGame; import java.awt.Graphics; import java.awt.Image; //父类的鱼 public class Fish { int length,height;//鱼的宽高 int x,y;//初始位置 boolean isMoveLeft=true;//鱼的初始方向 //原图片的坐标左上角和右下角(裁剪) int sx1,sy1; int sx2,sy2; int step; int zhanli; Image img;//鱼的图片 //绘制 public void draw(Graphics g) {}; } 4.2 其他鱼（都是相似的） package FishGame; import java.awt.Graphics; import java.util.Timer; import java.util.TimerTask; public class Fish_1 extends Fish{ int xx; int change=0; public Fish_1() { action(); step=2; xx=(int)(Math.random()*2);//0或者1 switch(xx) {//出场位置 case 0: isMoveLeft=false; x=-68; break; case 1: isMoveLeft=true; x=1440; break; } y=(int)(Math.random()*900);//垂直位置 length= 68; height= 55; zhanli=1; //界面坐标 img = DataImg.fish08; } public void draw(Graphics g){ if(isMoveLeft) {//左移 sy1=height*change;; sx1=0; sy2=height+height*change; sx2=length; g.drawImage(img, x=x-4, y, x+length, y+height, sx1, sy1, sx2,sy2, null);//可以控制鱼的速度 } else {//右移 sx2=0; sy2=height*change;; sx1=length; sy1=height+height*change; g.drawImage(img, x=x+4, y, x+length, y+height, sx1, sy1, sx2,sy2, null); } } public void action(){ Timer timer = new Timer(); timer.schedule(new TimerTask() { @Override public void run() { change=(++change)%step; } },20,500); } }

每条鱼里都有单独的时间线程，每0.5秒切换一次鱼的图片，达到游动动态效果

package FishGame; import java.awt.*; import java.util.Timer; import java.util.TimerTask; public class Fish_2_1 extends Fish{ int xx; int change=0; public Fish_2_1() { step=3; action(); xx=(int)(Math.random()*2); switch(xx) { case 0: isMoveLeft=false; x=-96; break; case 1: isMoveLeft=true; x=1440; break; } y=(int)(Math.random()*900); length= 90; height= 29; zhanli=2; //界面坐标 img = DataImg.fish06; } public void draw(Graphics g){ if(isMoveLeft) {//左移 sy1=height*change;; sx1=0; sy2=height+height*change; sx2=length; g.drawImage(img, x=x-3, y, x+length, y+height, sx1, sy1, sx2,sy2, null); } else {//右移 sx2=0; sy2=height*change;; sx1=length; sy1=height+height*change; g.drawImage(img, x=x+3, y, x+length, y+height, sx1, sy1, sx2,sy2, null); } } public void action(){ Timer timer = new Timer(); timer.schedule(new TimerTask() { @Override public void run() { change=(++change)%step; } },20,500); } } package FishGame; import java.awt.*; import java.util.Timer;

case 1: isMoveLeft=true; x=1440; break; } y=(int)(Math.random()*900); length= 96; height= 29; zhanli=2; //界面坐标 img = DataImg.fish12; } public void draw(Graphics g){ if(isMoveLeft) {//左移 sy1=height*change;; sx1=0; sy2=height+height*change; sx2=length; g.drawImage(img, x=x-3, y, x+length, y+height, sx1, sy1, sx2,sy2, null); } else {//右移 sx2=0; sy2=height*change;; sx1=length; sy1=height+height*change; g.drawImage(img, x=x+3, y, x+length, y+height, sx1, sy1, sx2,sy2, null);

case 1: isMoveLeft=true; x=1440; break; } y=(int)(Math.random()*900); length= 110; height=60; zhanli=3; //界面坐标 img = DataImg.lantern; } public void draw(Graphics g){ if(isMoveLeft) {//左移 sy1=336+height*change;; sx1=330; sy2=336+height+height*change; sx2=336+length; g.drawImage(img, x=x-3, y, x+length, y+height, sx1, sy1, sx2,sy2, null); } else {//右移 sx2=330; sy2=336+height*change;; sx1=330+length; sy1=336+height+height*change; g.drawImage(img, x=x+3, y, x+length, y+height, sx1, sy1, sx2,sy2, null); } } public void action(){ Timer timer = new Timer(); timer.schedule(new TimerTask() { @Override public void run() { change=(++change)%step; } },20,500); } } package FishGame; import java.awt.*; import java.util.Timer; import java.util.TimerTask; public class Fish_4 extends FishGame.Fish { int xx; int change=0; public Fish_4() { step=4; action(); xx=(int)(Math.random()*2); switch(xx) { case 0: isMoveLeft=false; x=-310; break; case 1: isMoveLeft=true; x=1440; break; } y=(int)(Math.random()*900); length= 310; height= 104; zhanli=3; //界面坐标 img = DataImg.fish03; } public void draw(Graphics g){ if(isMoveLeft) {//左移 sy1=height*change;; sx1=0; sy2=height+height*change; sx2=length; g.drawImage(img, x=x-2, y, x+length, y+height, sx1, sy1, sx2,sy2, null); } else {//右移 sx2=0; sy2=height*change;; sx1=length; sy1=height+height*change; g.drawImage(img, x=x+2, y, x+length, y+height, sx1, sy1, sx2,sy2, null); } } public void action(){ Timer timer = new Timer(); timer.schedule(new TimerTask() { @Override public void run() { change=(++change)%step; } },20,500); } } package FishGame; import java.awt.*; import java.util.Timer; import java.util.TimerTask; public class Fish_5 extends Fish { int xx; int change=0; public Fish_5() { step=2; action(); xx=(int)(Math.random()*2); switch(xx) { case 0: isMoveLeft=false; x=-380; break; case 1: isMoveLeft=true; x=1440; break; } y=(int)(Math.random()*900); length= 380; height= 210; zhanli=4; //界面坐标 img = DataImg.fish17; } public void draw(Graphics g){ if(isMoveLeft) {//左移 sy1=height*change;;

在FishFrame.java里运行main就可以开始游戏原本我的课设是有登入界面的(涉及数据库这里已经删除了。。长这样) 在这里插入图片描述
