I have the gameplay of connect four, and I have made a board, but I need to change it all so that the becker robot code is being used. The board of connect 4 should be built from the becker city layout, and the robots should somehow form red or blue counters. If you could create the final code that creates this all. Right now my code will produce the game but as a text based game. I need it to be visual and interactive.

Here is the code I have so far:

import becker.robots.City; import becker.robots.Direction; import becker.robots.Robot; import becker.robots.Thing; import becker.robots.Wall; import java.util.Scanner;

public class Connect4 extends City{

public static void main(String[] args) { Scanner in = new Scanner(System.in); //Creating the size of the board char[][] grid = new char[6][7]; //Here we are itializing the array for (int row = 0; row < grid.length; row++) { for (int col = 0; col < grid[0].length; col++) { grid[row][col] = ' '; } } //Starting move int turn = 1; char player = 'R'; boolean winner = false; //The player can take a turn while (winner == false && turn <= 42) { boolean validPlay; int play; do { display(grid); System.out.print("Player " + player + ", choose a column: "); play = in.nextInt(); //We are checking if the play is valid validPlay = validate(play,grid); } while (validPlay == false); //Here the checker drops for (int row = grid.length-1; row >= 0; row--) { if(grid[row][play] == ' ') { grid[row][play] = player; break; } } //Checking to see if there is a winner winner = isWinner(player,grid); //Switch players if (player == 'R') { player = 'B'; } else { player = 'R'; } turn++; } display(grid); if (winner) { if (player=='R') { System.out.println("Black won"); } else { System.out.println("Red won"); } } else { System.out.println("Tie game"); } } //Public Static Main Bracket KEEP //Creating board public static void display(char[][] grid) { System.out.println(" 0 1 2 3 4 5 6"); System.out.println("---------------"); for (int row = 0; row < grid.length; row++) { System.out.print("|"); for (int col = 0; col < grid[0].length; col++) { System.out.print(grid[row][col]); System.out.print("|"); } System.out.println(); System.out.println("---------------"); } System.out.println(" 0 1 2 3 4 5 6"); System.out.println(); } //Public Static Main Bracket KEEP //**fixing holes in the code**// public static boolean validate(int column, char[][] grid) { //Checking if the column is valid if (column < 0 || column > grid[0].length) { return false; } //Checking if the column is full if (grid[0][column] != ' ') { return false; } return true; } //Public Static Main Bracket KEEP public static boolean isWinner(char player, char[][] grid) { //checking for 4 counters across for(int row = 0; row
