• Constant：用于存放不可变的参数
• Explode：爆炸类
• GameObject：所有实体的父类
• GameUtil：加载图片的工具类
• MyGameFrame：主体
• Plane：飞机类
• Shell：飞机类

图片

代码实现

不可更改的游戏数据：

package game;/*** 存放不可更改的游戏数据* * @author 浅墨**/
public class Constant {public static final int GAME_WIDTH = 500; // 游戏界面宽度public static final int GAME_HEIGHT = 500; // 游戏界面高度public static final int explode_x = 115; // 游戏结束后时间显示的位置xpublic static final int explode_y = 200; // 游戏结束后时间显示的位置y
}

读取图片：

package game;
/*** 读取图片*/
import java.awt.Image;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.URL;import javax.imageio.ImageIO;public class GameUtil {//工具类私有化public GameUtil() {}//读取图片public static Image getImage(String path) {BufferedImage bi=null;try {URL u=ClassLoader().getResource(path);bi&#ad(u);} catch (IOException e) {e.printStackTrace();}return bi;}
}

游戏中所有的实体的父类：

package game;import java.awt.Graphics;
import java.awt.Image;
import java.awt.Rectangle;/*** 游戏中所有物体的父类* @author 浅墨**/
public class GameObject {private Image img;	//图片private int speed;	//移动速度private double x;	//x坐标private double y;	//y坐标private int width;	//宽度private int height;	//高度//多次画出图片位置public void drawSelf(Graphics g) {g.drawImage(img, (int)x,(int)y, null);}/*** 返回物体所在的矩形，便于后续的碰撞检测* @return*/public Rectangle getRect() {return new Rectangle((int)x,(int)y,width,height);}public GameObject(Image img, int speed, double x, double y, int width, int height) {super();this.img = img;this.speed = speed;this.x = x;this.y = y;this.width = width;this.height = height;}public GameObject(Image img, double x, double y) {super();this.img = img;this.x = x;this.y = y;}public GameObject() {super();}public Image getImg() {return img;}public void setImg(Image img) {this.img = img;}public int getSpeed() {return speed;}public void setSpeed(int speed) {this.speed = speed;}public double getX() {return x;}public void setX(double x) {this.x = x;}public double getY() {return y;}public void setY(double y) {this.y = y;}public int getWidth() {return width;}public void setWidth(int width) {this.width = width;}public int getHeight() {return height;}public void setHeight(int height) {this.height = height;}}

炮弹：

package game;import java.awt.Color;
import java.awt.Graphics;/*** 炮弹类* * @author 浅墨**/
public class Shell extends GameObject {double degree; // 移动的弧度public Shell() {setX(200);setY(200);setWidth(10);setHeight(10);setSpeed(2);degree = Math.random() * Math.PI * 2; // 生成[0,2π)之间的随机数}public void draw(Graphics g) {Color c = g.getColor();g.setColor(Color.YELLOW);// 填充一个点(炮弹)g.fillOval((int) getX(), (int) getY(), getWidth(), getHeight());// 改变炮弹的飞行角度setX(getX() + getSpeed() * s(degree));setY(getY() + getSpeed() * Math.sin(degree));// 炮弹碰到边界反弹(当碰到边界时，沿着碰撞的方向翻转，实现改变方向)if (getX() < 0 || getX() > Constant.GAME_WIDTH - getWidth()) {degree = Math.PI - degree;}if (getY() < 30 || getY() > Constant.GAME_HEIGHT - getHeight()) {degree = -degree;}g.setColor(c);}
}

飞机：

package game;import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.KeyEvent;/*** 飞机类* * @author 浅墨**/
public class Plane extends GameObject {boolean left;boolean up;boolean right;boolean down;boolean live=true;/*** 重写画笔，持续刷新位置*/@Overridepublic void drawSelf(Graphics g) {if(live) {g.drawImage(getImg(), (int) getX(), (int) getY(), null);if(left&&getX()>0) {setX(getX()-getSpeed());}if(right&&getX()<480) {setX(getX()+getSpeed());}if(up&&getY()>30) {setY(getY()-getSpeed());}if(down&&getY()<470) {setY(getY()+getSpeed());}		}}public Plane(Image img, double x, double y) {this.setImg(img);this.setX(x);this.setY(y);setSpeed(3);	//给移动速度赋初值
//		this.Height(null));
//		this.Width(null));this.setHeight(10);this.setWidth(10);}//键盘按下某个键，则增加某个方向移动public void addDirection(KeyEvent e) {switch (e.getKeyCode()) {case KeyEvent.VK_LEFT:left = true;break;case KeyEvent.VK_UP:up = true;break;case KeyEvent.VK_RIGHT:right = true;break;case KeyEvent.VK_DOWN:down = true;break;default:break;}}//键盘按下某个键，则取消某个方向移动public void minusDirection(KeyEvent e) {switch (e.getKeyCode()) {case KeyEvent.VK_LEFT:left = false;break;case KeyEvent.VK_UP:up = false;break;case KeyEvent.VK_RIGHT:right = false;break;case KeyEvent.VK_DOWN:down = false;break;default:break;}}}

爆炸：

package game;import java.awt.Graphics;
import java.awt.Image;/*** 爆炸类* * @author 浅墨**/
public class Explode {private double x; // x地址private double y; // y地址static Image[] imgs = new Image[16];static {for (int i = 0; i < 16; i++) {imgs[i] = Image("explode/e" + (i + 1) + ".gif");imgs[i].getWidth(null);}}int count;// 计数public void draw(Graphics g) {if (count <= 15) {g.drawImage(imgs[count], (int) x, (int) y, null);count++;}}public Explode(double x, double y) {super();this.x = x;this.y = y;}}
