Question

这是一个在控制台和绘图面板中创建游戏连接四的类，我在connectedFour方法中遇到问题，它确定某人是否连续获得了4张光盘。问题是，我不知道如何设置我的for循环来检查连续四个光盘的阵列这是我的代码：

import java.util.*;
import java.awt.*;


public class ConnectFour{

   public static void main(String[] args){
      //board
      DrawingPanel panel = new DrawingPanel(550,550);
      int rowAvailable;
      Graphics g = panel.getGraphics();
      g.drawLine(0,0,0,500);
      g.drawLine(0,0,500,0);
      g.drawLine(500,0,500,427);
      g.drawLine(0,427,500,427);
      for(int i = 0; i< 6; i++){
         for(int j= 0; j<= 6; j++){
            g.setColor(Color.YELLOW);
            g.fillRect(j*71,i*71,71,71);
            g.setColor(Color.WHITE);
            g.fillOval(j*71,i*71,71,71); 

         }
      }

      //setBlankArray
      Scanner console = new Scanner(System.in);
      char[][] board = new char[6][7];
      for(int j = 0;j <= 6; j++){
         for(int i= 0; i < 6; i++){
            board[i][j] = ' ';
         }
      }
      boolean isBlack = true;
      boolean isRed = false;
      int column = 0;
      boolean playersTurn = true;
      boolean rightNum = false;

      //oneTurn
      while(getWinner(board, playersTurn)){

         if(isBlack == true){

Answer 1

我会通过检查光盘放置后是否符合游戏获胜条件来实现此目的。这样，您不会在每次移动后迭代整个电路板。

无论如何，试试这个：

替换

while (gameWon == false ){

与

while (!connectedFour(board, playersTurn)) {

我认为这不会完全解决您的问题，因为您发布的代码看起来有一些其他问题。
