5.添加玩家飞机并渲染到界面上

1.分析出FlySprite 精灵类 父类_
/*
精灵类:玩家机，敌机，子弹，道具机等元素都属于精灵对象
*/
_public abstract class FlySprite {
protected BufferedImage image;
protected int x;
protected int y;
protected int width;
protected int height;
protected boolean dead;

_/**<br />     * 初始化精灵信息<br />     */<br />    _public abstract void init();
_/**<br />     * 绘制<br />     * _**_@param _**_g<br />     */<br />    _public void draw(Graphics g){<br />        g.drawImage(image, x, y, width, height, null);<br />    }
_/**<br />     * 销毁<br />     */<br />    _public abstract void destroy();<br />}<br />第二步 2创建玩家类

public class Hero extends FlySprite{
public Hero(){
init();
}

@Override<br />    public void init() {<br />         BufferedImage img = ImageLoaderUtil._load_("hero1.png");<br />    this.image = img;<br />    this.width = img.getWidth() / 2;<br />    this.height = img.getHeight() / 2;<br />    this.x = (FlyFrame._WIDTH_- this.width) / 2;<br />    this.y = (FlyFrame._HEIGHT_- this.height - 50);<br />    }<br />    @Override<br />    public void destroy() {
}<br />}<br />3.面板上画出飞机<br />public static Hero _hero _= new Hero();<br />@Override<br />public void paint(Graphics g) {<br />    //画背景图片<br />    g.drawImage(_background_, x, y, bgWidth, bgHeight, null);<br />    paintState(g);<br />    _hero_.draw(g);<br />}
