整个游戏由3个类构成。Bird类,Pipe类,stage类
第一步:首先写一个Bird类
//鸟类
public class Bird {
private int flyHeight;//飞行高度
private int xpos;//距离y轴(窗口左边缘)的位置,
public static int Up=1;//向上飞
public static int Down=-1;//向下飞
public Bird()
{
flyHeight=200;
xpos=30;
}
public void fly(int direction)
{
if(direction==Bird.Up)
flyHeight-=20;//每次向上飞20m
if(direction==Bird.Down)
flyHeight+=20;//每次向下飞20m
}
public int getFlyHeight()//获得当前飞行高度
{
return flyHeight;
}
public int getXpos()//获得当前鸟的水平位置
{
return xpos;
}
public Boolean hit(Pipe pipe[])//检测是否碰到管道。只有在鸟经过管道的过程才有可能相撞
{
for(int i=0;i<pipe.length;i++)//遍历管道进行检测,是否相撞
{
if(getXpos()+20>=pipe[i].getXpos()&&getXpos()<=pipe[i].getXpos()+20)//鸟经过管道
if(flyHeight<pipe[i].getUpHeight()||flyHeight>pipe[i].getDownHeight())//鸟与管道相撞
return true;
}
return false;
}
}
public class Pipe {
private int upHeight;//表示顶管道端的高度
private int downHeight;//表示底端管道段的高度
private int xpos;
public Pipe()
{
upHeight=0;
downHeight=0;
xpos=0;
}
public Pipe(int maxHeight,int xpos)//给管道一个最大总长度(maxHeight)=upHeight+downHeight。还有管道的水平位置
{
double num;
num=Math.random();
while(num==0)
num=Math.random();
upHeight=(int) (maxHeight*num);//随机产生一个顶端管道段高度(<maxHeight)
downHeight=maxHeight-upHeight;//用总长度减去upHeight
this.xpos=xpos;
}
public void setXpos(int xpos)
{
this.xpos=xpos;
}
public int getXpos()
{
return xpos;
}
public int getUpHeight()
{
return upHeight;
}
public int getDownHeight()
{
return downHeight;
}
public String toSting()
{
return "("+upHeight+","+downHeight+")";
}
}
最后一步,写好舞台类,即操作游戏的类
import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.lang.reflect.Array;
import java.util.Timer;
import java.util.TimerTask;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class stage extends JPanel{
private Pipe pipe[];//管道数组
private Bird bird;//鸟
private int space;//上下管道之间的间隔
public JLabel scoreBoard;//计分面板
private int score;//计分
public stage()
{
space=150;//<span style="font-family: Arial, Helvetica, sans-serif;">上下管道之间的间隔为150</span>
score=0;
scoreBoard=new JLabel("得分:"+score);
pipe=new Pipe[5];//总共5跟根
for(int i=0;i<pipe.length;i++)
{
pipe[i]=new Pipe(400-space,i*130+110);//柱子每隔110m放一根
//System.out.println(pipe[i].toSting());
}
bird=new Bird();
}
public void play()
{
Timer timer=new Timer();//定时任务,即使不操作也能动
timer.schedule(new TimerTask()
{
public void run()
{
if(bird.hit(pipe))//碰到,重置所有数据成员
{
//System.out.println("碰到了");
score=0;
scoreBoard.setText("得分:"+score);
pipe=new Pipe[10];
for(int x=0;x<pipe.length;x++)
pipe[x]=new Pipe(400-space,x*130+110);
bird=new Bird();
}
else{//没碰到
//System.out.println("没碰到");
bird.fly(Bird.Down);//鸟默认向下飞
for(int x=0;x<pipe.length;x++)//管道每次往前移动10m,造成鸟向右移动的效果
{
pipe[x].setXpos(pipe[x].getXpos()-10);
}
score=score+10;
scoreBoard.setText("得分:"+score);
}
repaint();
}
}, 0, 1000);//在不操作的情况下,每一秒飞一次
this.requestFocus();//获取”输入“焦点
this.addKeyListener(new KeyAdapter() {//加入键盘时间
public void keyPressed(KeyEvent e)
{
if(e.getKeyCode()==38)
<span style="white-space:pre"> </span>action(Bird.Up);
else if(e.getKeyCode()==40)
action(Bird.Down);
});
}
public void action(int direction)//按下上下方向键后执行的函数
{
if(bird.hit(pipe))
{
//System.out.println("碰到了");
score=0;
scoreBoard.setText("得分:"+score);
pipe=new Pipe[10];
for(int x=0;x<pipe.length;x++)
pipe[x]=new Pipe(400-space,x*130+110);
bird=new Bird();
}
else{
//System.out.println("没碰到");
if(direction==Bird.Up)
{
bird.fly(Bird.Up);
}
else if(direction==Bird.Down)
{
bird.fly(Bird.Down);
}
for(int x=0;x<pipe.length;x++)//管道每次往前移动10m,造成鸟向右移动的效果
{
pipe[x].setXpos(pipe[x].getXpos()-10);
}
score=score+10;
scoreBoard.setText("得分:"+score);
}
repaint();
}
public void paint(Graphics g)
{
g.setColor(g.getColor());
g.fillRect(0, 0, getWidth(), getHeight());//用默认颜色清屏
g.setColor(Color.red);
g.fill3DRect(bird.getXpos(), bird.getFlyHeight(), 20, 20, true);//红色画鸟
g.setColor(Color.green);
for(int i=0;i<pipe.length;i++)//绿色画管道
{
g.fill3DRect(pipe[i].getXpos(), 0, 20, pipe[i].getUpHeight(), true);
g.fill3DRect(pipe[i].getXpos(),pipe[i].getUpHeight()+space, 20, pipe[i].getDownHeight(), true);
}
if(pipe[0].getXpos()+20<=0)//如果第一根管道出界,就删掉第一根管道,把后面的往前挪,再新创建一根管道
{
for(int i=1;i<pipe.length;i++)
pipe[i-1]=pipe[i];
pipe[pipe.length-1]=new Pipe(400-space,(pipe.length-1)*130+110);
//System.out.println(pipe[pipe.length-1].toSting());
}
}
public static void main(String[] args) {
// TODO Auto-generated method stub
JFrame jf=new JFrame("flappyBird");
stage app=new stage();
jf.setLayout(null);
app.setBounds(0,20,600,400);
app.scoreBoard.setBounds(0, 0, 100, 20);
jf.add(app);
jf.add(app.scoreBoard);
jf.setSize(610, 460);
jf.setVisible(true);
app.play();//游戏开始
}
}
