这里是单个图片的漂浮效果，自己修改一下图片的路径和名称就好了，看能不能帮助你
用java做游戏，怎么让背景图片滚动啊
首先需要一个大图片bg，长度为bgWeight，它作为背景，相当于一个首尾相连的画卷，人物走动的话，它就滚动
int pos=0;//它记录窗口坐标（左边）在bg的偏移；
pos=(pos+moveSpeed)%bgWeight;
然后根据pos的位置绘制背景，有可能你是绘制 bg的尾部+bg的头部 来形成完整的背景
经典代码：
public Ribbon(int movS, BufferedImage im) {
bim = im; //im就是背景图片
xImHead = 0;//当前游戏窗口左边在背景图片中的坐标
pWidth = GamePanel.WIDTH;游戏窗口宽
pHeight = GamePanel.HEIGHT;游戏窗口高
width = bim.getWidth();背景图片宽度
moveSize = movS;移动距离
}
public void draw(Graphics g) /* Consider 5 cases:考虑5种情况
// when xImHead == 0, draw only the im head
//when xImHead 0, draw the im tail and im head, or only the im tail.
//when xImHead 0, draw the im tail, or the im tail and im head
// xImHead can range between -width to width (exclusive)
*/ {
if (xImHead == 0) // draw im head at (0,0)//情况1
{
drawRibbon(g, bim, 0, pWidth, 0, pWidth);
}
else if ((xImHead 0) (xImHead pWidth)) {//情况2
// draw im tail at (0,0) and im head at (xImHead,0)
drawRibbon(g, bim, 0, xImHead, width - xImHead, width); // im tail
drawRibbon(g, bim, xImHead, pWidth, 0, pWidth - xImHead); // im head
}
else if (xImHead = pWidth) // only draw im tail at (0,0)，情况3
{
drawRibbon(g, bim, 0, pWidth,
width - xImHead, width - xImHead + pWidth); // im tail
}
else if ((xImHead 0) (xImHead = pWidth - width)) {//情况4
drawRibbon(g, bim, 0, pWidth, -xImHead, pWidth - xImHead); // im body
}
else if (xImHead pWidth - width) { //情况5
// draw im tail at (0,0) and im head at (width+xImHead,0)
drawRibbon(g, bim, 0, width + xImHead, -xImHead, width); // im tail
drawRibbon(g, bim, width + xImHead, pWidth,
0, pWidth - width - xImHead); // im head
}
} // end of display()

怎么在GUI中用键盘控制图片运动？java问题？
废话不多说，直接上代码

java语言里怎么让图象移动到指定位置啊,最好用一小段代码说明.
改变规制时候的X Y就行了.伪代码如下.
int x =0,y=0,;
x++; y++;
g.drawImage( "图片信息" , x, y,锚点);
大概就这样图片就动了.你想移动到哪加个判断就行了.
