如何解决如何更新二维数组代码中蛇和梯子的位置？
public class ChutesAndLadders2d {
public static void main(String[] args) {
// TODO Auto-generated method stub
int[][] numbersOnBoard = new int [6][6];
boardSetUpA (numbersOnBoard);
printTwoD(numbersOnBoard);
}
public static void boardSetUpA (int[][]twoD) {
//Square with even size
//even rows
for (int row = 0;row<twoD.length; row ++) {
if (row %2 ==0) {
int num = twoD.length*(twoD.length-row);
for (int col = 0; col<twoD[row].length; col ++ ) {
twoD[row][col] = num;
num--;
}
}//
else {
int num = twoD.length*(twoD.length-(row + 1))+ 1;
for (int col = 0; col<twoD[row].length; col ++ ) {
twoD[row][col] = num;
num++;
}
}
}//for row
}//
public static void printTwoD(int [][] array){
for (int row = 0; row < array.length; row++){
for (int column = 0; column < array[row].length; column++){
System.out.print(array[row][column] + "\t");
}
System.out.println();
}
}
public static void boardDetails(String[][]board) {
for (int row = 0;row<board.length; row++){
for (int col = 0;col<board[row].length; col++){
if( col+2 == row||col+1 == row*2 ){
board[row][col] = "Lad"; // Append value
}
else if (col*2 == row|| row*2 == col){
board[row][col] = "Cht";// Append value
}
else {
board[row][col] = " ";
}
}
board[board.length-1][0] = "Start";
if (board.length%2 ==0) {
board[0][0] = "End";}
else {
board[0][board.length-1]="End";
}
}
}
public static void printBoard (int[][]twoD,String[][]strTwoD) {
//Printing
for (int row = 0;row<twoD.length;row++) {
for (int col = 0;col<twoD[row].length;col++) {
System.out.print(twoD[row][col] + " "+strTwoD[row][col]+"\t\t");
}
System.out.println("\n");
}
}
}
这是我用于设置蛇和梯子游戏的入门代码。我还尝试在板上设置滑槽/蛇和梯子，但它没有打印。我应该如何修复它以及如何开发此代码以使其具有三种方法：在玩家到达蛇、梯子和掷骰子后，从一个地方到另一个地方更新他的动作？
解决方法
是否可以使用 2D Array 实现 Shutes & Ladders 游戏？当然！这在面向对象的语言（如 Java）中有意义吗？我不知道....
你需要什么？
- 一块方板，例如36 个运动场。
- 两个运动场之间的联系。 （棚子和梯子）
- 棋子和骰子。
- 输出比赛场地（作为文本或图形）的渲染器。
- 允许输入并将所有内容连接到正常游戏的程序。
这是一个使用 List 而不是 Array 的示例。如果出于您的目的有必要，那当然可以更改。
希望对你有帮助。
P.S .: 开始后，棋盘上会显示场号。 Shutes 显示为红线。梯子作为绿线。键盘上的 1-6 键模拟掷骰子..
