敌军tank被干掉的动画效果（16）

爆照的效果是一张张图片。
将爆炸的图片加载到内存中：
public static BufferedImage[] explodes = new BufferedImage[16];
for(int i=1;i<=16;i++){
explodes[i] = ImageIO.read(ResourceMgr.class.getClassLoader().getResourceAsStream(“images/e”+i+".gif"));
}
定义一个爆炸类：（万物皆对象）
package com.tavon.tank;

import java.awt.*;

public class explode {
public static final int WIDTH = ResourceMgr.explodes[0].getWidth();
public static final int HEIGHT = ResourceMgr.explodes[0].getHeight();
private int x, y;
private TankFrame tankFrame = null;

public explode(int x, int y, TankFrame tankFrame) {this.x = x;this.y = y;this.tankFrame = tankFrame;
}private int step = 0;public static int getWIDTH() {return WIDTH;
}public static int getHEIGHT() {return HEIGHT;
}public TankFrame getTankFrame() {return tankFrame;
}public void setTankFrame(TankFrame tankFrame) {this.tankFrame = tankFrame;
}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;
}public void paint(Graphics graphics) {graphics.drawImage(ResourceMgr.explodes[step++],x,y,null);if(step >= ResourceMgr.explodes.length){tankFrame.explodes.remove(this);}
}

}
肯定同时有好几个地方爆炸，所以爆炸也是一个集合，然后画出来，只有碰撞的时候才会爆炸，代码实现：
List explodes = new ArrayList<>(); //爆炸的集合
for(int i=0;i<explodes.size();i++){
explodes.get(i).paint(graphics);//画出爆炸
}
//在碰撞出添加爆炸
public void collidewith(Tank tank) {
if(this.group == tank.getGroup()) return;//如果当前的子弹跟坦克是一个组的就不碰撞检测。
Rectangle rect1 = new Rectangle(this.x, this.y, WIDTH, HEIGHT);
Rectangle rect2 = new Rectangle(tank.getX(), tank.getY(), Tank.WIDTH, Tank.HEIGHT);
if (rect1.intersects(rect2)) {
tank.die();
this.die();
tankFrame.explodes.add(new explode(x,y,tankFrame));
}
}
这样爆炸的效果就出来了。
