利用面向对象的思想，来封装具体的实体，因为所有的实体都具有通用的属性和行为，则抽为基类定义。
/**
* 飞行物基类
*/
public abstract class FlyingObject {
public static final int ALIVE = 0;//活着
public static final int DEAD = 1;//死亡
public static final int DELETABLE = 2;//可删除
public int state = ALIVE;//状态
public Image image;
public int x;
public int y;
//英雄机或子弹构造
public FlyingObject(Image image, int x, int y) {
this.image = image;
this.x = x;
this.y = y;
}
//敌机构造
public FlyingObject(Image image) {
this.image = image;
int w1 = ShootGame.WIDTH;//屏幕宽
int w2 = (int) this.image.getWidth();
int h2 = (int) this.image.getHeight();
Random random = new Random();
this.x = random.nextInt(w1 - w2);
this.y = h2 / 2;
}
public int getState() {
return state;
}
public void setState(int state) {
this.state = state;
}
public Image getImage() {
return image;
}
public void setImage(Image image) {
this.image = image;
}
public int getX() {
return x;
}
public void setX(int x) {
this.x = x;
}
public int getY() {
return y;
}
public void setY(int y) {
this.y = y;
}
int index = 1;
public void setImage(Image[] images) {
if (state == ALIVE) {
image = images[0];
} else if (state == DEAD) {
image = images[index];
index++;
if (index == images.length) {
state = DELETABLE;
}
} else {
image = null;
}
}
public abstract void setImage();
}
再通过继承方式，再定义自己独特的行为及属性
/**
* 英雄机
*/
