setBounds
public void setBounds(int x,
int y,
int width,
int height)移動組件并調整其大小。由 x 和 y 指定左上角的新位置，由 width 和 height 指定新的大小。
參數：
x - 組件的新 x 坐標
y - 組件的新 y 坐標
width - 組件的新 width
height - 組件的新 height
button.setBonds(button.getBonds().getX(),button.getBonds().getY()-50,button.getBonds().getWidth
(),button.getBonds().getHeight() )
button.getBonds().getY()-50, 就是向上移動坐標的關鍵
代碼主要為以下：

字符跳動好像不的行額...我只知道什么顏色啊！字體啊什么的或者加動態(tài)加音樂什么的！對了你可以這樣嘛！判斷文本的長度！如果長度在某個段內就調用Substring（）截取字符串來設定大小顏色什么的！再創(chuàng)建幾個Icon ir= new ImageIcon(); 插入些制定找好的圖片 你看怎么樣~??？加音樂如下！ 可以這樣！ 也是取值到某段就放MUSIC 通過Java提供的AudioClip類就可以播放了：
mid = java.applet.Applet.newAudioClip(this.getClass().getResource(midUrl[0]));mid.loop();
//循環(huán)mid.play();
//播放mid.stop();
//停止檢舉midUrl[0]是文件的路徑 不知道兄弟幫到你沒！哎！我也就這點功力了。嘿嘿
去學習A星尋路，可以得到最短路徑，其中也包括了繞開障礙物的代碼，然后就是動畫的圖片切換了，如果說要地圖跟隨主角移動，那個應該是滾屏操作，也就是說你主角往右走，超過窗口或者屏幕（全屏）坐標一半的時候，地圖整個往左移動，速度和主角的一樣就出來效果了。如果你看不懂A星的話，那咂就給你一段BFS的C++語言代碼，自己轉換成JAVA代碼寫法（就是改些關鍵字，有不少經典的游戲算法都來自C/C++）就可以了，這個是簡化版的A星尋路，一樣可以找到最近的路徑，你把path 這個路徑記錄下來再換算成像素位置就可以得到行走的具體步伐了...
