Java 游戏鼠标运动
原标题:Java Game Mouse Movement

我正在玩一个游戏,我们必须用捕捉者来捕捉从窗口顶部掉下来的球。 抓获者只能左/右移动。

示例:http://puu.sh/xeq8

如果我想让捕鼠者和老鼠一起移动,我应该朝哪个方向看/朝哪个方向看?

现在,我有一个捕捉者使用键盘——我使用了Keyliister ,但我对鼠标并不确定。

最理想的情况是,当鼠标移动在 JPANEL 移动时,我喜欢捕鼠者左/右移动。 或者类似的东西是理想的。

最佳回答

使用鼠标移动倾听器 :

myPanel.addMouseMotionListener(new MouseAdapter() { 
   public void mouseMoved(MouseEvent me) { 
      //move the catcher
      //use me.getX() to have the horizontal position of the mouse
      //eg : catcher.setX(me.getX())
   } 
}); 
问题回答

使用 < code> mouseMotionListener 来通知鼠标的位置,我认为您也需要单击以捕捉该下落球,使用 < code > MouseListener 或 MouseAdapter

当您单击您的 MouseListener 将会被通知,当他们移动鼠标行距时,您的 MouseMotionListener 将会被触发回调 。
