用jquery实现俄罗斯方块游戏

要使用 jQuery 实现俄罗斯方块游戏，需要使用 HTML、CSS 和 JavaScript 进行开发。由于涉及到大量的布局和游戏逻辑，这是一个相对复杂的任务。以下是一个简化的示例，用 jQuery 实现俄罗斯方块游戏的基本框架：

HTML 代码：

html
```
<!DOCTYPE html>
<html>
<head>
  <title>Tetris Game</title>
  <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
  <div id="game-container">
    <div id="board"></div>
    <div id="score">Score: <span id="score-value">0</span></div>
    <button id="start-btn">Start</button>
  </div>

css
```
#game-container {
  text-align: center;
}

#board {
  position: relative;
  display: inline-block;
  width: 300px;
  height: 600px;
  background-color: #f5f5f5;
  border: 1px solid #ccc;
}

#score {
  font-size: 24px;
  margin-bottom: 20px;
}

#start-btn {
  font-size: 20px;
  padding: 10px 20px;
  margin-top: 20px;
}
```
JavaScript 代码（script.js）：

javascript
```
$(document).ready(function() {
  var board = $('#board');
  var scoreSpan = $('#score-value');
  var score = 0;
  var boardWidth = 10;
  var boardHeight = 20;
  var blockSize = 30;
  var boardArray = [];
  var currentPiece;
  var currentX;
  var currentY;
  var interval;
  var isGameRunning = false;

function movePiece(dirX, dirY) {
    var newX = currentX + dirX;
    var newY = currentY + dirY;
    if (!collision(currentPiece, newX, newY)) {
      currentX = newX;
      currentY = newY;
    }
  }

function randomPiece() {
    var pieces = [
      { shape: [[1, 1, 1, 1]] },
      { shape: [[1, 1], [1, 1]] },
      { shape: [[1, 1, 0], [0, 1, 1]] },
      { shape: [[0, 1, 1], [1, 1, 0]] },
      { shape: [[1, 1, 1], [0, 1, 0]] },
      { shape: [[1, 1, 1], [1, 0, 0]] },
      { shape: [[1, 1, 1], [0, 0, 1]] }
    ];
    return pieces[Math.floor(Math.random() * pieces.length)];
  }

function startGame() {
    boardArray = [];
    createBoard();
    currentPiece = randomPiece();
    currentX = Math.floor(boardWidth / 2) - Math.floor(currentPiece.shape[0].length / 2);
    currentY = 0;
    score = 0;
    scoreSpan.text(score);
    isGameRunning = true;
    interval = setInterval(function() {
      dropPiece();
      drawBoard();
      drawPiece();
    }, 500);
  }

function endGame() {
    clearInterval(interval);
    isGameRunning = false;
    alert('Game Over! Your score: ' + score);
  }

$(document).keydown(function(e) {
    if (!isGameRunning) {
      return;
    }
    switch (e.keyCode) {
      case 37: // Left arrow key
        movePiece(-1, 0);
        break;
      case 38: // Up arrow key
        rotatePiece();
        break;
      case 39: // Right arrow key
        movePiece(1, 0);
        break;
      case 40: // Down arrow key
        dropPiece();
        break;
    }
  });

$('#start-btn').click(function() {
    if (isGameRunning) {
      return;
    }
    startGame();
  });
});
```
请注意，这只是一个简化的俄罗斯方块游戏示例，可能还需要进行进一步的优化和改进来提高游戏的体验和可玩性。你可以根据需要自行修改和扩展代码。
