Schreiben Sie ein Schlangenspiel in Java

废话不多说, 直接奉上代码:

Frame.java

 Paketschlange; import java.awt.Graphics;import java.awt.Menu;import java.awt.MenuBar;import java.awt.MenuItem;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.awt .event.KeyEvent;import java.awt.event.KeyListener; import javax.swing.JFrame; öffentliche Klasse Frame erweitert JFrame implementiert KeyListener { /** * */ Boolean isAlive; Boolean isPause; Panel-Panel; Zeichenrichtung; private static final long serialVersionUID = 1L; public Frame(){ // TODO Automatisch generierter Konstruktor-Stub setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(300,300); addKeyListener(this); Panel = neues Panel(); add(panel); setVisible(true); isAlive = true; isPause = false; Richtung = neues Zeichen('d'); MenuBar menuBar = new MenuBar(); Menü menu = new Menu("menu"); MenuItem reset = new MenuItem("newgame"); MenuItem pause= new MenuItem("pause"); pause.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent e) { // TODO Automatisch generierter Methoden-Stub if(!isPause) isPause= true; else isPause= false; } }); reset.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent e) { // TODO Automatisch generierter Methoden-Stub reset(); } }); menu.add(reset); menu.add(pause); menuBar.add(menu); setMenuBar(menuBar); } public void reset(){ panel.reset(); isAlive = true; } @Override public void keyTyped(KeyEvent e) { // TODO Automatisch generierter Methoden-Stub } @Override public void keyPressed(KeyEvent e) { // TODO Automatisch generierter Methoden-Stub if(e.getKeyCode()==KeyEvent.VK_UP ) Richtung = 'w'; if(e.getKeyCode()==KeyEvent.VK_DOWN) Direction = 's'; if(e.getKeyCode()==KeyEvent.VK_LEFT) Direction = 'a'; if(e.getKeyCode()==KeyEvent.VK_RIGHT) Direction = 'd'; } @Override public void keyReleased(KeyEvent e) { // TODO Automatisch generierter Methoden-Stub } public void paint(Graphics g){ panel.repaint(); } }

Launch.java

 Paketschlange; import java.util.Timer;import java.util.TimerTask; öffentliche Klasse Launch erweitert TimerTask { Frame frame = new Frame(); public Launch() { // TODO Automatisch generierter Konstruktor-Stub } boolean crashWall(){ SnakeBody sb = frame.panel.snake.getFirst(); if((sb.x<0)||(sb.y<0)||(sb.x>=Panel.LINE)||(sb.y>=Panel.LINE)) return true; sonst gibt false zurück; } void initial(){ frame.panel.snake.add(newBody()); frame.panel.food = newBody(); } @Override public void run() { // TODO Automatisch generierter Methoden-Stub if(frame.panel.snake.isEmpty()) initial(); if(frame.isAlive) if(!frame.isPause){ if(goStraight()) frame.isAlive = false; frame.repaint(); } if(crashWall()) frame.isAlive = false; } SnakeBody newBody(){ SnakeBody sb = new SnakeBody(); boolesche Überlappung = true; while(overlap){ overlap =false; sb.x = (int) (Math.random()*(Panel.LINE-2)+1); sb.y = (int) (Math.random()*(Panel.LINE-2)+1); if(!frame.panel.snake.isEmpty()) for(SnakeBody s : frame.panel.snake) if(sb.equals(s)) Overlap =true; } return jdn; } void eat(SnakeBody sb){ frame.panel.snake.addFirst(sb); } boolean goStraight(){ boolean result = false; SnakeBody sb =new SnakeBody(frame.panel.snake.getFirst()); frame.panel.snake.removeLast(); if(frame.direction=='w') sb.turnUp(); if(frame.direction=='s') sb.turnDown(); if(frame.direction=='a') sb.turnLeft(); if(frame.direction=='d') sb.turnRight(); for(SnakeBody s : frame.panel.snake){ if(sb.equals(s)) result = true; } frame.panel.snake.addFirst(sb); if(sb.equals(frame.panel.food)){ if(frame.direction=='w') frame.panel.food.turnUp(); if(frame.direction=='s') frame.panel.food.turnDown(); if(frame.direction=='a') frame.panel.food.turnLeft(); if(frame.direction=='d') frame.panel.food.turnRight(); eat(frame.panel.food); frame.panel.food = newBody(); } Ergebnis zurückgeben; } public static void main(String[] args){ // TODO Automatisch generierter Methoden-Stub Launch timertask = new Launch(); Timer timer = new Timer(); timer.schedule(timertask,0,500); } }

Panel.java

 Paketschlange; import java.awt.Color;import java.awt.Graphics;import java.util.LinkedList; import javax.swing.JPanel; öffentliche Klasse Panel erweitert JPanel { /** * */ private static final long serialVersionUID = 1L; public LinkedList<SnakeBody> Snake = new LinkedList<SnakeBody>(); static final int LINE = 10; SnakeBody food = new SnakeBody(-99,-99); public Panel() { // TODO Automatisch generierter Konstruktor-Stub } public void reset(){ Snake.clear(); } public void paint(Graphics g){ g.setColor(Color.white); g.fillRect(0, 0, getWidth(), getHeight()); for(SnakeBody sb : Snake){ g.setColor(Color.black); g.drawRect(sb.x*getWidth()/LINE,sb.y*getHeight()/LINE,getWidth()/LINE,getHeight()/LINE); g.setColor(Color.orange); g.fillRect(sb.x*getWidth()/LINE,sb.y*getHeight()/LINE,getWidth()/LINE,getHeight()/LINE); } g.setColor(Color.red); g.fillRect(food.x*getWidth()/LINE,food.y*getHeight()/LINE,getWidth()/LINE,getHeight()/LINE); }}

SnakeBody.java

 Paketschlange; Klasse SnakeBody { int x; int y; public SnakeBody() { // TODO Automatisch generierter Konstruktor-Stub x = 0; y = 0; } public SnakeBody(int a,int b){ x = a; y = b; } public SnakeBody(SnakeBody sb){ this(sb.x,sb.y); } public void turnUp(){ y--; } public void turnDown(){ y++; } public void turnLeft(){ x--; } public void turnRight(){ x++; } boolean equal(SnakeBody s){ if((x==sx)&&(y==sy)) return true; sonst gibt false zurück; } }

以上所述就是本文给大家分享的贪吃蛇的全部代码了, 希望能够对大家熟练掌握java有所帮助.
