以下是一个简单的 Java 飞机大战游戏中升级子弹的源代码示例:
```
public class Bullet {
private int x;
private int y;
private int speed;
private int power;
private Image image;
public Bullet(int x, int y, int speed, int power, Image image) {
this.x = x;
this.y = y;
this.speed = speed;
this.power = power;
this.image = image;
}
// Getter and setter methods
public void move() {
y -= speed;
}
public boolean hit(Boss boss) {
Rectangle bulletRect = new Rectangle(x, y, image.getWidth(null), image.getHeight(null));
Rectangle bossRect = new Rectangle(boss.getX(), boss.getY(), boss.getImage().getWidth(null), boss.getImage().getHeight(null));
return bulletRect.intersects(bossRect);
}
public void draw(Graphics g) {
g.drawImage(image, x, y, null);
}
public void upgrade() {
power *= 2;
speed *= 2;
}
}
```
在游戏中,当玩家的子弹打中 BOSS 时,可以调用 upgrade() 方法升级子弹,使其威力和速度翻倍。
