Unity supported Tetris engine, supporting manual and ai play

Tetris Engine

C# Tetris Engine written to be pluggable for both manually play and automatic AI play.
Supporting 3rd party AI algorithms by using the AI engine's IAlgorithm interface.

Usage

Manual play

var gameManager = new GameManager(20, 10);

// Game loop
while (!gameManager.GameState.IsGameOver())
{
    gameManager.OnGameLoopStep();

    // Simple user input.
    if (keyboard.Input == Left) {
        gameManager.MoveBlock(Move.Left);
    }
    ...
}

AI Agent

See example console runner at ./Runners/Tetris.Engine.AIConsoleRunner

var gameManager = new GameManager(20, 10);
var ai = new Engine(
    new TetrisAi(
        new TetrisAiWeights
            {
                ColumnTransitions = 0.8024363520000000f,
                LandingHeight = -0.1958289440000000f,
                NumberOfHoles = 5.0289489999999999f,
                RowTransitions = -0.4794300500000000f,
                RowsCleared = -2.0772042300000000f,
                WellSums = 0.4410647000000000f
            }));

IEnumerator moveIterator = null;
var blockNumber = -1;

// Game loop
while (!gameManager.GameState.IsGameOver())
{
    // Print state and sleep wait run loop logic.
    PrintState(gameManager);
    Thread.Sleep(50);

    gameManager.OnGameLoopStep();

    if (moveIterator != null && moveIterator.MoveNext())
    {
        gameManager.MoveBlock((Move)moveIterator.Current);
        continue;
    }

    // Make sure we only calculate best move once per spawned block.
    if (blockNumber != gameManager.GameStats.BlocksSpawned)
    {
        var steps = ai.GetNextMove(gameManager.BoardManager);
        moveIterator = steps.Moves.GetEnumerator();
        blockNumber = gameManager.GameStats.BlocksSpawned;
    }
}
