好的,下面是一个简单的俄罗斯方块游戏的Qt代码示例: ```cpp #include <QApplication> #include <QWidget> #include <QGridLayout> #include <QLabel> #include <QTimer> #include <QKeyEvent> const int ROWS = 20; const int COLUMNS = 10; const int SQUARE_SIZE = 30; class Tetris : public QWidget { public: Tetris(QWidget *parent = nullptr); protected: void keyPressEvent(QKeyEvent *event) override; private: QLabel *square[ROWS][COLUMNS]; QTimer *timer; int board[ROWS][COLUMNS]; int currentShape[4][4]; int currentX; int currentY; int currentShapeIndex; int score; void initBoard(); void initWindow(); void initTimer(); void newShape(); void drawSquare(int row, int column, int shapeIndex); void undrawSquare(int row, int column); void updateBoard(); bool isCollision(int x, int y, int shapeIndex); void rotateShape(); void moveShape(int dx, int dy); void dropShape(); void clearFullRows(); void gameOver(); }; Tetris::Tetris(QWidget *parent) : QWidget(parent) { initBoard(); initWindow(); initTimer(); newShape(); } void Tetris::keyPressEvent(QKeyEvent *event) { switch (event->key()) { case Qt::Key_Left: moveShape(-1, 0); break; case Qt::Key_Right: moveShape(1, 0); break; case Qt::Key_Down: dropShape(); break; case Qt::Key_Space: rotateShape(); break; } } void Tetris::initBoard() { for (int i = 0; i < ROWS; ++i) { for (int j = 0; j < COLUMNS; ++j) { board[i][j] = 0; } } } void Tetris::initWindow() { QGridLayout *layout = new QGridLayout(this); for (int i = 0; i < ROWS; ++i) { for (int j = 0; j < COLUMNS; ++j) { square[i][j] = new QLabel(this); square[i][j]->setFixedSize(SQUARE_SIZE, SQUARE_SIZE); square[i][j]->setStyleSheet("border: 1px solid black;"); layout->addWidget(square[i][j], i, j); } } setLayout(layout); } void Tetris::initTimer() { timer = new QTimer(this); connect(timer, &QTimer::timeout, this, &Tetris::dropShape); timer->start(500); } void Tetris::newShape() { static const int shapes[7][4][4] = { {{1, 1, 0, 0}, {1, 1, 0, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}}, {{0, 2, 2, 0}, {2, 2, 0, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}}, {{3, 3, 0, 0}, {0, 3, 3, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}}, {{4, 0, 0, 0}, {4, 4, 4, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}}, {{0, 0, 5, 0}, {5, 5, 5, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}}, {{6, 6, 6, 6}, {0, 0, 0, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}}, {{7, 7, 7, 0}, {0, 0, 7, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}} }; currentShapeIndex = qrand() % 7; for (int i = 0; i < 4; ++i) { for (int j = 0; j < 4; ++j) { currentShape[i][j] = shapes[currentShapeIndex][i][j]; } } currentX = COLUMNS / 2 - 2; currentY = 0; if (isCollision(currentX, currentY, currentShapeIndex)) { gameOver(); } updateBoard(); } void Tetris::drawSquare(int row, int column, int shapeIndex) { QColor color; switch (shapeIndex) { case 1: color = Qt::red; break; case 2: color = Qt::green; break; case 3: color = Qt::blue; break; case 4: color = Qt::yellow; break; case 5: color = Qt::cyan; break; case 6: color = Qt::magenta; break; case 7: color = Qt::gray; break; } square[row][column]->setStyleSheet(QString("background-color: %1; border: 1px solid black;").arg(color.name())); } void Tetris::undrawSquare(int row, int column) { square[row][column]->setStyleSheet("border: 1px solid black;"); } void Tetris::updateBoard() { for (int i = 0; i < ROWS; ++i) { for (int j = 0; j < COLUMNS; ++j) { if (board[i][j] == 0) { undrawSquare(i, j); } else { drawSquare(i, j, board[i][j]); } } } for (int i = 0; i < 4; ++i) { for (int j = 0; j < 4; ++j) { if (currentShape[i][j] != 0) { drawSquare(currentY + i, currentX + j, currentShapeIndex + 1); } } } } bool Tetris::isCollision(int x, int y, int shapeIndex) { for (int i = 0; i < 4; ++i) { for (int j = 0; j < 4; ++j) { if (currentShape[i][j] == 0) { continue; } int newX = x + j; int newY = y + i; if (newX < 0 || newX >= COLUMNS || newY >= ROWS) { return true; } if (newY < 0) { continue; } if (board[newY][newX] != 0) { return true; } } } return false; } void Tetris::rotateShape() { int newShape[4][4]; for (int i = 0; i < 4; ++i) { for (int j = 0; j < 4; ++j) { newShape[i][j] = currentShape[3 - j][i]; } } if (!isCollision(currentX, currentY, newShape)) { for (int i = 0; i < 4; ++i) { for (int j = 0; j < 4; ++j) { currentShape[i][j] = newShape[i][j]; } } updateBoard(); } } void Tetris::moveShape(int dx, int dy) { if (!isCollision(currentX + dx, currentY + dy, currentShape)) { currentX += dx; currentY += dy; updateBoard(); } } void Tetris::dropShape() { if (!isCollision(currentX, currentY + 1, currentShape)) { currentY++; updateBoard(); } else { for (int i = 0; i < 4; ++i) { for (int j = 0; j < 4; ++j) { if (currentShape[i][j] != 0) { board[currentY + i][currentX + j] = currentShapeIndex + 1; } } } updateBoard(); clearFullRows(); newShape(); } } void Tetris::clearFullRows() { for (int i = ROWS - 1; i >= 0; --i) { bool full = true; for (int j = 0; j < COLUMNS; ++j) { if (board[i][j] == 0) { full = false; break; } } if (full) { for (int k = i; k > 0; --k) { for (int j = 0; j < COLUMNS; ++j) { board[k][j] = board[k - 1][j]; } } score += 10; updateBoard(); } } } void Tetris::gameOver() { timer->stop(); QMessageBox::information(this, "Game Over", QString("Your score is %1").arg(score)); } int main(int argc, char *argv[]) { QApplication a(argc, argv); Tetris tetris; tetris.show(); return a.exec(); } ``` 这个程序使用了一个二维数组来表示俄罗斯方块游戏面板上的方块,使用 QLabel 来绘制方块。具体实现请参考代码注释。
