private void draw()
    {
if(a){
        if (score <= 4000){
            g.drawImage(imgBack1, 0, backY, 0);
        if(backY>0&&backY<CanvasHeight)
         g.drawImage(imgBack1, 0, backY-imgBack2.getHeight(), 0);
        }
        
        //背景1
        
        if (score > 4000 && score <= 7000)
        {
            g.drawImage(imgBack2, 0, backY, 0); //背景2
           if(backY>0&&backY<CanvasHeight)
         g.drawImage(imgBack2, 0, backY-imgBack2.getHeight(), 0);
        }
        if (score > 7000 && score <= 10100)
        {
            g.drawImage(imgBack3, 0, backY, 0); //背景3
                    if(backY>0&&backY<CanvasHeight)
         g.drawImage(imgBack3, 0, backY-imgBack2.getHeight(), 0);
        }

        
        for (i = 0; i < 3; i++)
        {
            bullets[i].draw(g);
        }
        enemy1.draw(g);
        enemy2.draw(g);
        bonus.draw(g);
        for (i = 0; i < 8; i++)
        {
            enemy3456[i].draw(g);
        }
}
if(!a)
{
bullets1.draw(g);
}
player.paint(g);
        
        g.drawImage(imgState, 0, CanvasHeight - 10, g.TOP

 g.LEFT);
        g.setColor(0xffff00);
        g.fillRect(8, CanvasHeight - 10+3, energy, 4);
        if (isExplored)
        {
            g.drawImage(imgExplored, expX, expY, g.TOP
