Sea Battle

Description

The main goal of the game is to kill all enemy's ships before the enemy kills yours.

I didn't use any frameworks, libraries or anything else, just pure PHP.

AI

I wrote 3 algorithms:

1. RandomAI - just shooting randomly without trying to kill damaged ships.
2. ImprovedRandomAI - shooting randomly, but when ship is damaged, AI is trying to kill it.
3. SmartAI - it's working better than ImprovedRandomAI, but it has a little bit more complicated implementation.

How to

1) Change AI

// src/Game.php

public function startNewGame(): void
{
    $this->enemyPlayer = new EnemyPlayer(new AI\SmartAI());
    // $this->enemyPlayer = new EnemyPlayer(new AI\RandomAI());
    // $this->enemyPlayer = new EnemyPlayer(new AI\ImprovedRandomAI());
}

2) Change boards sizes

// src/Board/AbstractBoard.php

public const WIDTH = 10;
public const HEIGHT = 10;

3) Change ships on board

// src/Board/ShipBoard.php

public const SHIPS_TO_CREATE = [
    ["ship size" => 4, "number" => 1],
    ["ship size" => 3, "number" => 2],
    ["ship size" => 2, "number" => 3],
    ["ship size" => 1, "number" => 4],
];
