Usage

To import and render the react component, note all props are optional and the TicTacToe component takes no props:

import { UltimateTicTacToe, TicTacToe } from 'ultimate_tic_tic_toe';

class App extends React.Component {

  render() {
    return <div>
      <UltimateTicTacToe 
      playerOne="human" 
      playerTwo="bot_level_two" 
      loopGame={true} 
      moveDelay={50}
    />
    <TicTacToe />
    </div>
  }
}

Prop	Data type	Default value	Values available	Additional information
playerOne	string	`'human'`	`'human'`, `'bot_level_zero'`, `'bot_level_one', 'bot_level_two'`	The higher the level the higher the skill of the bot
playerTwo	string	`'human'`	`'human'`, `'bot_level_zero'`, `'bot_level_one', 'bot_level_two'`	The higher the level the higher the skill of the bot
loopGame	boolean	`false`	`true`, `false`	Resets the game once it's complete, useful for comparing bots over many games
moveDelay	number	`1000`	A number in milliseconds	Represents the time between bot moves

To import and run the client only:

import { Game } from 'ultimate-tic-tac-toe'
const game = new Game()

while (!game.isGameOver()) {
  const moves = game.getMoves()
  const move = moves[Math.floor(Math.random() * moves.length)];
  game.move(move)
}
console.log(game.print());
