弹弹球小游戏(Java)

作者:互联网

游戏规则:利用键盘上的->或者<-控制方向,用球拍接住小球,否则游戏结束!

该代码主要利用了GUI的绘图,用Timer保证球拍和小球位置的更新,用适配器KeyAdapter获取用户的指令,参考代码如下,需要改进之处请各位大佬多多指正

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class checkb {
	//设置frame
	Frame frame=new Frame("欢迎林giegie来到弹弹球小游戏");
	private final int TABLE_WIDTH =300;
	private final int TABLE_HEIGHT =400;
	//设置小球
	private final int BALL_SIZE=16;
	private int BALLX=120;
	private int BALLY=20;
	private int SPEEDX=10;
	private int SPEEDY=5;
	//设置拍子
	private final int RACKET_WIDTH=60;
	private final int RACKET_HEIGHT=20;
	private int RACKETX=120;
	private int RACKETY=340;
	//结束标志
	private boolean isover=false;
	//时间对象
	private Timer timer;
	//画布
	private class Mycanvas extends Canvas{
		@Override
		public void paint(Graphics g) {
			// TODO Auto-generated method stub
			super.paint(g);
			//游戏结束、进行时
			if(isover){
				g.setColor(Color.black);
				g.setFont(new Font("Times",Font.BOLD,30));
				g.drawString("林giegie败北", 150, 200);
			}else{
				//画球、球拍
                g.fillOval(BALLX, BALLY, BALL_SIZE, BALL_SIZE);	
                g.fillRect(RACKETX, RACKETY, RACKET_WIDTH, RACKET_HEIGHT);
			}
			
		}
	}
	//组装组件
	public void inti(){
	        class listenere extends KeyAdapter{
			@Override

				// TODO Auto-generated method stub
				super.keyPressed(e);
				int s=e.getKeyCode();
				if(RACKETX>=0&&s==KeyEvent.VK_LEFT){
					RACKETX-=10;
				}
				if(RACKETX<=TABLE_WIDTH-RACKET_WIDTH&&s==KeyEvent.VK_RIGHT){
					RACKETX+=10;
				}
			}
			}
	        listenere listener=new listenere();
	        Mycanvas Mycan=new Mycanvas();
	        frame.addKeyListener(listener);
	        Mycan.addKeyListener(listener);
	    class task implements ActionListener{
	    	@Override
	    	public void actionPerformed(ActionEvent e) {
	    		// TODO Auto-generated method stub
	    		//小球到达窗口两侧
	    		if(BALLX<=0||BALLX>=TABLE_WIDTH-BALL_SIZE)
	    			SPEEDX=-SPEEDX;
	    		//小球到达顶部
	    		if(BALLY<=0)
	    			 SPEEDY=-SPEEDY;
	    		//小球接触到球拍
	    		if(BALLX>RACKETX&&BALLX<RACKETX+RACKET_WIDTH&&BALLY>=RACKETY-BALL_SIZE)
	    			SPEEDY=-SPEEDY;
	    		//球拍没接住小球
	    		if(BALLY>=RACKETY&&(BALLX<RACKETX-BALL_SIZE||BALLX>RACKETX+BALL_SIZE)){
	    			isover=true;
	    		    Mycan.repaint();
	    		    timer.stop();
	    	}
	    	BALLX+=SPEEDX;
	    	BALLY+=SPEEDY;
	    	Mycan.repaint();
	    	}
	    	}
	        timer = new Timer(100,new task());
	        timer.start();
	        Mycan.setPreferredSize(new Dimension(TABLE_WIDTH,TABLE_HEIGHT));
	        frame.add(Mycan);

	        //设置frame最佳大小,并可视
	        frame.pack();
	        frame.setVisible(true);
	}

	public static void main(String[] args) {
		// TODO Auto-generated method stub
           new checkb().inti();
	}
