JAVA五子棋中如何实现重新开始和悔棋的功能
一般来说是不应该像你这样写的,应该是把要画的步骤写在组件的被覆写的paintComponent函数里,然后在你响应事件的函数里直接掉用该组件的repaint()函数即可。repaint函数是会去掉该组件的paintComponent()函数的。至于你这么写为啥不行,这个我也不清楚,据我猜测,repaint函数要做的事情是刷新组件,并且重新去画一遍,不过这个步骤不一定是立即完成,可能有延迟。总之在你画那些棋子之后,它又干了一些事情,导致你画的棋子没了(但这不会影响到它自己想去画的东西,即paintComponent()函数里的东西),另外不要忘了,覆写paintComponent时,第一行要写,super.paintComponent(g),这是去画它原来有的东西(比如加上去的按钮,文本框之类的东西)
例如下面:
12345678910111213141516171819202122232425262728293031323334353637class PanelM extends JPanel{ ImageIcon icon = new ImageIcon("app.gif"); JLabel jl = new JLabel(icon, SwingConstants.CENTER); int x, y; private ListInteger listX = new ArrayListInteger(); private ListInteger listY = new ArrayListInteger(); public PanelM() { add(jl); addMouseListener(new MouseAdapter() { public void mousePressed(MouseEvent m) { x = m.getX(); y = m.getY(); listX.add(x); listY.add(y); repaint(); } }); } public void paintComponent(Graphics g) { super.paintComponent(g); for (int i = 0; i listX.size(); i++) { g.fillOval(listX.get(i), listY.get(i), 20, 20); } }}
java五子棋怎么画ER图
先画正方形,然后画两条对折线完成。
第一步、我们先来画一画五子棋的棋盘,画出一个棋盘,画一个四方形。
第二步、接着我们画一画棋盘的棋盘格,横横竖竖的横要平,竖要直溜溜。
第三步、接着我们画出棋盘里面的棋子,黑色和白色的棋子就完成啦。
想用Java 做五子棋游戏而且是多线程的应该怎么做
直接上程序吧:
