JAVA Frame 窗体背景图片，首位相接滚动代码实例
背景图片连续滚动，程序已经跑过。前提！背景图片宽度比窗体长些，代码如下：
importJava.awt.Graphics;
importjava.awt.Image;
importjavax.swing.ImageIcon;
importmine.game.util.PropertiesUtil;
@SuppressWarnings("serial")
publicclassGameFrameextendsMyFrame{
privateImageimg=ImageUtil.imageLoad("image/bk.jpg");
doublemovs,speed=1,headmovs;
doublepWidth,pHeight,bgWidth;
@Override
publicvoidpaint(Graphicsg){
//g.drawImage(img,0,0,null);
//===================================================
pWidth=PropertiesUtil.getValue("Width","game.properties");
pHeight=PropertiesUtil.getValue("Height","game.properties");
bgWidth=newImageIcon(img).getIconWidth();
//movs+=speed;
if(bgWidth>pWidth+movs){
g.drawImage(img,0,0,(int)pWidth,(int)pHeight,(int)movs,0,(int)(pWidth+movs),(int)pHeight,null);
}
if(bgWidth<=pWidth+movs){
headmovs=pWidth+movs-bgWidth;
g.drawImage(img,0,0,(int)(pWidth-headmovs),(int)pHeight,(int)movs,0,(int)(bgWidth),(int)pHeight,null);
g.drawImage(img,(int)(pWidth-headmovs),0,(int)pWidth,(int)pHeight,0,0,(int)(headmovs),(int)pHeight,null);
if(headmovs>=pWidth){
//重新初始化所有变量数据，循环
movs=headmovs-pWidth;
}
}
movs+=speed;
//===================================================
}
publicstaticvoidmain(String[]args){
GameFramegf=newGameFrame();
gf.launchFrame();
}
}
//=================================

/**

@Override
publicvoidupdate(Graphicsg){
if(imgBuffer==null){
imgBuffer=(BufferedImage)createImage(this.getWidth(),this.getSize().height);//创建图形缓冲
//imgBuffer=newBufferedImage((int)this.getSize().getWidth(),(int)this.getSize().getHeight(),BufferedImage.TYPE_4BYTE_ABGR);//创建图形缓冲
}
gBuffer=imgBuffer.getGraphics();//获取图形缓冲区的图形上下文
gBuffer.fillRect(0,0,this.getWidth(),this.getHeight());
this.paint(gBuffer);//用paint方法中编写的绘图过程对图形缓冲区绘图
gBuffer.dispose();//释放图形上下文资源
g.drawImage(imgBuffer,0,0,null);//将图形缓冲区绘制到屏幕上
}
}

希望以上内容代码对您有所帮助
