How To Change If "O" Has Put Chess Man Then It Is Turn X Put Chess Man And Check Winner Of Array 2D In OOP Javascript?

This is function control Table. /** * @constructor * @param {Number} width - dimension width for table * @param {Number} height - dimension height for table */

Solution 1:

At some point you need to set the variable "ch" to indicate what player needs to go. Right now you have this code in your main function:

if (ch === 'O') {
  this.putChessman(x, y, this.playerTwo.ch);
} else {
  this.putChessman(x, y, this.playerOne.ch);
}

One thing you could try doing is returning whether putChessman succeeded.

putChessman: function (x, y, ch) {
  if (this.table.isEmptyAt(x, y) === true) {
    console.log('@ Other player already put on it');
    return true;   // CHANGED FROM THE CODE ABOVE
  } else {
    console.log('@ player ' + ch + ' put');
    this.table.setPosition(x, y, ch);
    return false;   // CHANGED FROM THE CODE ABOVE
  }

You can capture the result in your main function, and use it to decide what "ch" should be.

if (ch === 'O') {
  result = this.putChessman(x, y, this.playerTwo.ch);
  if(result) {
      ch = 'X';
  }
} else {
  result = this.putChessman(x, y, this.playerOne.ch);
  if(result) {
      ch = 'O';
  }
}

Hope this helps!
