java游戏悔棋代码 java实现悔棋思路

java五子棋悔棋代码根据我的代码加

// 悔棋

public void goback() {

if (chessCount == 0) //判断剩余棋子数

return;

chessList[chessCount - 1] = null; //chessList是棋子数组

chessCount--;

if (chessCount 0) {

xIndex = chessList[chessCount - 1].getX(); // xIndex, yIndex 当前刚下棋子的索引

yIndex = chessList[chessCount - 1].getY();

}

isBlack = !isBlack;

repaint();

}

Q2: 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java游戏悔棋代码的，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java游戏悔棋代码我也不清楚，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java游戏悔棋代码：

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); } }}
