学校请了达内来培训8天（其实是学校和培训机构各取所需），主要学了JPanel类。
上主要代码：

敌机，子弹，补给品，和飞机爆炸效果4个类都放在集合里，个人感觉在这里用集合比数组方便，因为并不知道会有多少个元素，而且感觉打开程序的速度也有提升（后来加上音乐后又变慢了- -）.计时器控制一下如敌机，补给品和子弹的出现频率，还有控制爆炸画面不能太快。敌机和补给品的出现率还有Math.Random()控制，可以根据时间或分数来调整概率。
敌机类（子弹类等类似）
package com.raikou.practise.plane; import java.awt.Graphics; import java.awt.Image; import javax.swing.ImageIcon; public class Enemys { private int y; private int x; private int type; private int score; private int hit; private boolean isHited = false; private Image enemyplane; public Enemys(int x, int y, int type) { super(); this.y = y; this.x = x; this.type = type; switch (type) { case 1: score = 1000; hit = 1; break; case 2: score = 6000; hit = 6; break; case 3: score = 30000; hit = 12; break; default: break; } enemyplane = new ImageIcon("./images/shoot.png").getImage(); } public int getHit() { return hit; } public void setHit(int hit) { this.hit = hit; } public void drawEnemys(Graphics g) { if (!isHited) { if (type == 1) g.drawImage(enemyplane, x, y, x + 49, y + 40, 539, 613, 588, 653, null); else if (type == 2) g.drawImage(enemyplane, x, y, x + 69, y + 93, 0, 0, 69, 93, null); else if (type == 3) g.drawImage(enemyplane, x, y, x + 165, y + 256, 338, 750, 503, 1006, null); } else { if (type == 1) g.drawImage(enemyplane, x, y, x + 49, y + 40, 539, 613, 588, 653, null); else if (type == 2) g.drawImage(enemyplane, x, y, x + 69, y + 93, 432, 529, 501, 622, null); else if (type == 3) g.drawImage(enemyplane, x, y, x + 165, y + 256, 165, 750, 330, 1006, null); } } public boolean isHited() { return isHited; } public void setHited(boolean isHited) { this.isHited = isHited; } public void startMoving() { if (type == 1) y += 4; else if (type == 2) y += 3; else y += 2; } public int getScore() { return score; } public int getType() { return type; } public int getY() { return y; } public int getX() { return x; } }
这个类包含敌机的一些基本属性，如何坐标，大小，还有运动轨迹和速度。碰撞的判断写在PlaneJPanel的线程中。
