matlab写一个俄罗斯方块游戏

以下是一个简单版本的俄罗斯方块游戏的 MATLAB 代码：

“`matlab
function tetris()
% 初始化游戏参数
rows = 20; % 游戏界面行数
cols = 10; % 游戏界面列数
score = 0; % 游戏得分

% 创建游戏界面矩阵
board = zeros(rows, cols);

% 创建一个空的方块
currentPiece = createPiece();

% 开始游戏循环
while 1
% 显示游戏界面
draw(board, currentPiece, score);

% 获取玩家操作
userInput = input(‘请输入操作（a: 左移 s: 下移 d: 右移 q: 旋转）:’, ‘s’);

% 执行玩家操作
switch userInput
case ‘a’
currentPiece.y = currentPiece.y – 1;
case ‘s’
currentPiece.x = currentPiece.x + 1;
case ‘d’
currentPiece.y = currentPiece.y + 1;
case ‘q’
currentPiece.rotation = mod(currentPiece.rotation + 1, 4);
end

% 判断是否可以执行当前操作
if isValidMove(board, currentPiece)
% 执行当前操作
board = placePiece(board, currentPiece);
else
% 操作无效，判断是否游戏结束
if currentPiece.x == 1
% 游戏结束，退出循环
break;
end

% 将当前方块固定到游戏界面上
board = fixPiece(board, currentPiece);

% 消除满行并更新得分
[board, score] = clearLines(board, score);

% 创建一个新的方块
currentPiece = createPiece();
end
end

% 游戏结束，显示最终得分
draw(board, currentPiece, score);
disp(‘游戏结束！’);
end

% 创建一个新的方块
function piece = createPiece()
pieces = {
[1 1 1 1], % 横条形状
[1 1 1; 0 1 0], % T字形状
[1 1 0; 0 1 1], % Z字形状
[0 1 1; 1 1 0], % S字形状
[1 1; 1 1], % 方块形状
[1 1 1; 0 0 1], % L字形状
[1 1 1; 1 0 0] % J字形状
};

pieceIndex = randi(length(pieces));
piece = struct(‘shape’, pieces{pieceIndex}, ‘rotation’, 1, ‘x’, 1, ‘y’, 4);
end

% 显示游戏界面
function draw(board, currentPiece, score)
[rows, cols] = size(board);

% 清空命令窗口
clc;

% 显示得分
disp([‘得分：’ num2str(score)]);

% 绘制游戏界面
for i = 1:rows
line = ”;
for j = 1:cols
if i >= currentPiece.x && i < currentPiece.x + size(currentPiece.shape, 1) && j >= currentPiece.y && j < currentPiece.y + size(currentPiece.shape, 2) && currentPiece.shape(i - currentPiece.x + 1, j - currentPiece.y + 1) == 1 line = [line '*']; elseif board(i, j) == 1 line = [line '#']; else line = [line ' ']; end end disp(line); endend% 判断当前操作是否有效function isValid = isValidMove(board, currentPiece) [rows, cols] = size(board); % 获取当前方块的位置和形状 shape = currentPiece.shape; rotation = currentPiece.rotation; x = currentPiece.x; y = currentPiece.y; % 判断是否超出游戏界面 if x < 1 || x + size(shape, 1) - 1 > rows || y < 1 || y + size(shape, 2) - 1 > cols
isValid = false;
return;
end

% 判断是否与已经固定的方块重叠
for i = 1:size(shape, 1)
for j = 1:size(shape, 2)
if shape(i, j) == 1 && board(x + i – 1, y + j – 1) == 1
isValid = false;
return;
end
end
end

isValid = true;
end

% 将当前方块固定到游戏界面上
function newBoard = placePiece(board, currentPiece)
newBoard = board;

% 获取当前方块的位置和形状
shape = currentPiece.shape;
rotation = currentPiece.rotation;
x = currentPiece.x;
y = currentPiece.y;

% 将方块的形状设置到游戏界面中
for i = 1:size(shape, 1)
for j = 1:size(shape, 2)
if shape(i, j) == 1
newBoard(x + i – 1, y + j – 1) = 1;
end
end
end
end

% 将当前方块固定到游戏界面上并返回新的游戏界面
function newBoard = fixPiece(board, currentPiece)
newBoard = placePiece(board, currentPiece);
end

% 消除满行并更新得分
function [newBoard, newScore] = clearLines(board, score)
[rows, cols] = size(board);
newBoard = board;
newScore = score;

% 检查每一行是否满行
for i = rows:-1:1
if all(board(i, :) == 1)
% 移除满行
newBoard(i, :) = [];

% 新增空行在顶部
newBoard = [zeros(1, cols); newBoard];

% 增加得分
newScore = newScore + 1;
end
end
end

% 运行游戏
tetris();

运行上述代码后，会在命令窗口中启动一个简单的俄罗斯方块游戏。使用键盘输入字母 ‘a’、’s’、’d’ 可以左移、下移和右移方块，字母 ‘q’ 可以旋转方块。游戏结束时会显示最终得分。
