在《超级玛丽》中，只要按一下空格，人物就调跳一下，这个用java swing怎么实现！谢谢

要是 swing 的button 的话

setBounds

public void setBounds(int x,

int y,

int width,

int height)移动组件并调整其大小。由 x 和 y 指定左上角的新位置，由 width 和 height 指定新的大小。

参数：

x - 组件的新 x 坐标

y - 组件的新 y 坐标

width - 组件的新 width

height - 组件的新 height

button.setBonds(button.getBonds().getX(),button.getBonds().getY()-50,button.getBonds().getWidth

(),button.getBonds().getHeight() )

button.getBonds().getY()-50, 就是向上移动坐标的关键

如何在Java控制台输出动态效果(字符的跳动)

字符跳动好像不的行额...我只知道什么颜色啊！字体啊什么的或者加动态加音乐什么的！对了你可以这样嘛！判断文本的长度！如果长度在某个段内就调用Substring（）截取字符串来设定大小颜色什么的！再创建几个Icon ir= new ImageIcon(); 插入些制定找好的图片 你看怎么样~！？加音乐如下！ 可以这样！ 也是取值到某段就放MUSIC 通过Java提供的AudioClip类就可以播放了：

mid = java.applet.Applet.newAudioClip(this.getClass().getResource(midUrl[0]));mid.loop();

//循环mid.play();

//播放mid.stop();

//停止检举midUrl[0]是文件的路径 不知道兄弟帮到你没！哎！我也就这点功力了。嘿嘿

Java 鼠标控制人物移动，地图随人物移动

去学习A星寻路，可以得到最短路径，其中也包括了绕开障碍物的代码，然后就是动画的图片切换了，如果说要地图跟随主角移动，那个应该是滚屏操作，也就是说你主角往右走，超过窗口或者屏幕（全屏）坐标一半的时候，地图整个往左移动，速度和主角的一样就出来效果了。如果你看不懂A星的话，那咂就给你一段BFS的C++语言代码，自己转换成JAVA代码写法（就是改些关键字，有不少经典的游戏算法都来自C/C++）就可以了，这个是简化版的A星寻路，一样可以找到最近的路径，你把path 这个路径记录下来再换算成像素位置就可以得到行走的具体步伐了...
