飛機大戰項目
剛學Java時用Frame寫的一個飛機子彈的小遊戲項目，難度不大，學了frame的小夥伴可以試試手
核心包：
背景和飛機
遊戲窗口的實現，包含整個窗體的監聽
package GamePlane;
import java.awt.Color;
import java.awt.Font;
import java.awt.Frame;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.print.attribute.standard.SheetCollate;
public class MyGameFrame extends Frame{
Image planeImg = GameUtil.getImage("Image/plane.png");
Image bg = GameUtil.getImage("Image/bg.jpg");
Plane plane = new Plane(planeImg, 250, Constant.GAME_HEIGHT-150);
Shell[] shell = new Shell[20];
Explode bao ;
@Override
public void paint(Graphics g) {
g.drawImage(bg, 0, 0, null);
plane.drawSelf(g);
for(int i = 0;i<shell.length;i++)
{
Color c = g.getColor();
shell[i].drawSelf(g);
boolean boom = shell[i].getRect().intersects(plane.getRect());
for(int j=0;j<plane.all.size();j++) {
boolean coll = shell[i].getRect().intersects(plane.all.get(j).getRect());
if(coll)
{
shell[i].live = false;
plane.all.get(j).islive = false;
}
}
if(boom) {
plane.live = false;
for(i = 0;i<shell.length;i++) {
shell[i].live = false;
}
if(bao == null)
{
bao = new Explode(plane.x, plane.y);
}
bao.draw(g);
}
if(!plane.live)
{
g.setColor(Color.red);
Font f = new Font("宋體", Font.BOLD, 50);
g.setFont(f);
g.drawString("你輸了哈哈", (int)plane.x,(int) plane.y);
}
g.setColor(c);
}
}
class PaintThread extends Thread
{
@Override
public void run() {
while(true)
{
repaint();
try {
Thread.sleep(40);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
class KeyMonitor extends KeyAdapter {
@Override
public void keyPressed(KeyEvent e) {
plane.addDection(e);
}
@Override
public void keyReleased(KeyEvent e) {
plane.minusDection(e);
}
}
public void lunchFrame() {
this.setTitle("hello!This is the first Game");
this.setVisible(true);
this.setSize(Constant.GAME_WIDTH, Constant.GAME_HEIGHT);
this.setLocation(100, 100);
this.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
new PaintThread().start(); //啓動重畫窗口的線程
addKeyListener(new KeyMonitor()); //給窗口增加鍵盤的監聽
for(int i =0;i<shell.length;i++)
{
shell[i] = new Shell();
}
}
public static void main(String[] args) {
MyGameFrame f = new MyGameFrame();
f.lunchFrame();
}
private Image offScreenImage = null;
public void update(Graphics g) {
if(offScreenImage == null)
offScreenImage = this.createImage(Constant.GAME_WIDTH,Constant.GAME_HEIGHT);//這是遊戲窗口的寬度和高度
Graphics gOff = offScreenImage.getGraphics();
paint(gOff);
g.drawImage(offScreenImage, 0, 0, null);
}
}
飛機的實現（飛機可以發射子彈）
package GamePlane;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.KeyEvent;
import java.util.ArrayList;
import java.util.List;
public class Plane extends GameObject{
boolean left,right,up,down,space;
boolean live;
List<Bullet> all = new ArrayList<Bullet>();
public Plane (Image img,double x,double y)
{
live = true;
this.image = img;
this.x = x;
this.y = y;
speed = 10;
this.width = img.getWidth(null);
this.height = img.getHeight(null);
}
@Override
public void drawSelf(Graphics g) {
if(live)
{
g.drawImage(image, (int)x,(int) y, null);
oper();
for(int i = 0;i<all.size();i++)
{
new Thread(all.get(i)).start();
all.get(i).draw(g);
}
}
}
public void oper() {
if(left){
if(x>10)
{
x-=speed;
}
}
else if (down) {
if(y<Constant.GAME_HEIGHT-50)
{
y+=speed;
}
}
else if (right) {
if(x<Constant.GAME_WIDTH-30)
{x+=speed;}
}
else if (up) {
if(y>30)
{y-=speed;}
}
}
public void addDection(KeyEvent e) {
switch (e.getKeyCode()) {
case KeyEvent.VK_LEFT:
left = true;
break ;
case KeyEvent.VK_RIGHT:
right = true;
break;
case KeyEvent.VK_DOWN:
down = true;
break;
case KeyEvent.VK_UP:
up = true;
break;
case KeyEvent.VK_SPACE:
all.add(new Bullet(x, y));
break;
}
}
public void minusDection(KeyEvent e) {
switch (e.getKeyCode()) {
case KeyEvent.VK_LEFT:
left = false;
break ;
case KeyEvent.VK_RIGHT:
right = false;
break;
case KeyEvent.VK_DOWN:
down = false;
break;
case KeyEvent.VK_UP:
up = false;
break;
}
}
}
子彈的發射
package GamePlane;
import java.awt.Color;
import java.awt.Graphics;
public class Bullet extends GameObject implements Runnable {
boolean islive;
public Bullet(double x,double y)
{
this.x = x;
this.y = y;
speed = 3;
islive = true;
}
public void run() {
while(true) {
try {
Thread.sleep(500);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public void draw(Graphics g) {
if(islive) {
g.setColor(Color.BLUE);
y-=speed;
g.fillOval((int)x, (int)y,20, 20);
}
}
}
障礙時通過繪製圓形實現
package GamePlane;
import java.awt.Color;
import java.awt.Graphics;
public class Shell extends GameObject{
double degree;
boolean live;
public Shell()
{
x = 200;
y = 200;
width = 20;
height = 20;
speed = 3;
degree = Math.random()*Math.PI*2;
live = true;
}
@Override
public void drawSelf(Graphics g) {
if (live) {
Color c = g.getColor();
g.setColor(Color.YELLOW);
g.fillOval((int)x, (int)y, width, height);
x += Math.cos(degree)*speed;
y += Math.sin(degree)*speed;
if(x<0||x>Constant.GAME_WIDTH-width)
{
degree = Math.PI-degree;
}
if(y<30||y>Constant.GAME_HEIGHT-height)
{
degree = -degree;
}
g.setColor(c);
}
}
}
最後是爆炸效果的實現
package GamePlane;
import java.awt.Graphics;
import java.awt.Image;
public class Explode {
double x,y;
static Image[] imgs = new Image[16];
static {
for(int i = 0;i<16;i++)
{
imgs[i]=GameUtil.getImage("explode/explode/e" + (i + 1) + ".gif");
imgs[i].getWidth(null);
}
}
int count;
public void draw(Graphics g) {
if (count <= 15) {
g.drawImage(imgs[count], (int) x, (int) y, null);
count++;
}
}
public Explode(double x, double y) {
this.x = x;
this.y = y;
}
}

如果有興趣的小夥伴，也可以親手寫個小遊戲試試，下期更新貪喫蛇的Java項目啦，初學Java的小夥伴,可以關注我哦！下面貼上源碼：
