我正在制作一个横跨jbuttons网格布局的游戏,只允许移动到相邻的网格jbuttons。目标是尝试使其成为topleft(从btm右侧)。我认为这一切都是相关的:
//这是我的方法,以确定它是否是一个有效的移动(我不希望你能够移动到任何地方,但相邻的点
public boolean goodMove(int x, int y) {
int val = Math.abs(current.x - x) + Math.abs(current.y - y);
return val == 1;
}
//这是actionlister中的逻辑,一个大的if else循环,现在只引用gridlayout中的jbuttons(游戏面板)
public void actionPerformed(ActionEvent e) {
JButton clicked = (JButton) e.getSource();
if (clicked == SHOWMINES) {
if (SHOWMINES.getText().equals("Show Mines")) {
showMines();
SHOWMINES.setText("Hide Mines");
} else {
hideMines();
}
} else {
if (clicked == NEWGAME) {
newGame();
} else {
if (clicked == SHOWPATH) {
if (SHOWPATH.getText().equals("Show Path")) {
showPath();
SHOWPATH.setText("Hide Path");
} else {
hidePath();
}
} else {
if (clicked == OKAY) {
resetGridSize(Integer.parseInt(gridSizeInput.getText()));
newGame();
} else {
}
int gs = Integer.parseInt(gridSizeInput.getText());
for (int i = 0; i < gs - 1; i++) {
for (int j = 0; j < gs - 1; j++) {
if (clicked == grid[i][j]) {
if (goodMove(i, j)) {//debug tester ,this is where the problem is.
System.out.println("TEST");
current = new Point(i, j);
grid[i][j].setBackground(Color.green);
grid[i][j].setText("=");
}else{System.out.println("TEST2");}
}
}
}
}
}
}
}// end of action listener
Grid [] []是我的网格按钮数组,gridSizeInput是可以调整网格大小的文本字段。
提前致谢(我是编程新手,所以如果可以的话,请保持简单:)
编辑:我忘了提及,它没有识别我的if(goodMove())循环,它只是为我的其他人打印出两个。编辑:我的问题是为什么不工作,没有按钮会被识别为在我的网格中被点击,我想我想看看我写的东西是否明显错误。感谢。
编辑:好的,这是我所有按钮的整个动作监听器。这是我的第一篇文章,对不起,我没有更多的帮助 - 如果我能添加任何其他内容,请告诉我。
答案 0 :(得分:2)
你的问题可能就像你没有将你的for循环扩展得足够简单一样简单。尝试更改此内容:
for (int i = 0; i < gs - 1; i++) {
for (int j = 0; j < gs - 1; j++) {
到此:
for (int i = 0; i < gs; i++) {
for (int j = 0; j < gs; j++) {

这是我为测试这个概念而创建的最小代码示例:
import java.awt.Color;
import java.awt.GridLayout;
import java.awt.Point;
import java.awt.event.*;
import javax.swing.*;
public class Foo extends JPanel {
public static final int GRID_SIZE = 10;
private Point current;
private JButton[][] grid;
public Foo() {
ButtonListener listener = new ButtonListener();
setLayout(new GridLayout(GRID_SIZE, GRID_SIZE));
grid = new JButton[GRID_SIZE][GRID_SIZE];
for (int i = 0; i < grid.length; i++) {
for (int j = 0; j < grid[i].length; j++) {
grid[i][j] = new JButton(" ");
grid[i][j].addActionListener(listener);
add(grid[i][j]);
}
}
current = new Point(GRID_SIZE - 1, GRID_SIZE - 1);
}
private class ButtonListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
JButton clicked = (JButton) e.getSource();
// !! int gs = Integer.parseInt(gridSizeInput.getText());
int gs = GRID_SIZE;
// !! for (int i = 0; i < gs - 1; i++) {
// for (int j = 0; j < gs - 1; j++) {
for (int i = 0; i < gs; i++) {
for (int j = 0; j < gs; j++) {
if (clicked == grid[i][j]) {
if (goodMove(i, j)) {
System.out.println("TEST");
current = new Point(i, j);
grid[i][j].setBackground(Color.green);
grid[i][j].setText("=");
} else {
System.out.println("TEST2");
}
}
}
}
}
}
public boolean goodMove(int x, int y) {
int val = Math.abs(current.x - x) + Math.abs(current.y - y);
return val == 1;
}
private static void createAndShowGui() {
Foo mainPanel = new Foo();
JFrame frame = new JFrame("Foo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(mainPanel);
frame.pack();
frame.setLocationByPlatform(true);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGui();
}
});
}
}
