java俄罗斯方块游戏代码

编写一个完整的Java俄罗斯方块游戏代码是一个相对复杂的任务，因此我提供一个简化版本的实现，以便您了解基本的结构和思想。

board = new boolean[WIDTH][HEIGHT];
currentPiece = generateRandomPiece();
currentPieceX = WIDTH / 2 - 1;
currentPieceY = 0;
timer = new Timer(500, this);
timer.start();

}
private int[][] generateRandomPiece() {

int pieceType = random.nextInt(7);
// Define different Tetris pieces (I, J, L, O, S, T, Z)
int[][] piece;
switch (pieceType) {

break;
case 1:

int[][] rotatedPiece = new int[currentPiece[0].length][currentPiece.length];
for (int i = 0; i < currentPiece.length; i++) {

rotatedPiece[j][currentPiece.length - 1 - i] = currentPiece[i][j];

lineComplete = false;
break;
}
}
if (lineComplete) {
removeLine(y);
y++;
}
}
}
private void removeLine(int line) {
for (int y = line; y > 0; y--) {
for (int x = 0; x < WIDTH; x++) {
board[x][y] = board[x][y - 1];
}
}
}
private void gameOver() {
timer.stop();
JOptionPane.showMessageDialog(this, "Game Over!");
System.exit(0);
}
@Override
public void actionPerformed(ActionEvent e) {
if (canMove(0, 1)) {
movePiece(0, 1);
} else {
// The piece cannot move down, so place it on the board
drawPiece();
checkLines();
currentPiece = generateRandomPiece();
currentPieceX = WIDTH / 2 - 1;
currentPieceY = 0;
if (!canMove(0, 0)) {
gameOver();
}
}
}
private boolean canMove(int deltaX, int deltaY) {
for (int i = 0; i < currentPiece.length; i++) {

if (currentPiece[i][j] == 1) {
int newX = currentPieceX + i + deltaX;
int newY = currentPieceY + j + deltaY;
// Check if the new position is within bounds and not occupied
if (newX < 0 || newX >= WIDTH || newY < 0 || newY >= HEIGHT || board[newX][newY]) {
return false;
}
}
}
}
return true;
}
@Override
public void keyPressed(KeyEvent e) {
switch (e.getKeyCode()) {
case KeyEvent.VK_LEFT:
if (canMove(-1, 0)) {
movePiece(-1, 0);
}
break;
case KeyEvent.VK_RIGHT:
if (canMove(1, 0)) {
movePiece(1, 0);
}
break;
case KeyEvent.VK_DOWN:
if (canMove(0, 1)) {
movePiece(0, 1);
}
break;
case KeyEvent.VK_UP:
rotatePiece();
break;
}
}
@Override
public void keyTyped(KeyEvent e) {
}
@Override
public void keyReleased(KeyEvent e) {
}
@Override
public void paint(Graphics g) {
super.paint(g);
for (int x = 0; x < WIDTH; x++) {
for (int y = 0; y < HEIGHT; y++) {
if (board[x][y]) {
g.setColor(Color.BLUE);
g.fillRect(x * CELL_SIZE, y * CELL_SIZE, CELL_SIZE, CELL_SIZE);
g.setColor(Color.BLACK);
g.drawRect(x * CELL_SIZE, y * CELL_SIZE, CELL_SIZE, CELL_SIZE);
}
}
}
g.setColor(Color.RED);
for (int i = 0; i < currentPiece.length; i++) {
for (int j = 

java
0; j < currentPiece[0].length; j++) {
if (currentPiece[i][j] == 1) {
g.fillRect((currentPieceX + i) * CELL_SIZE, (currentPieceY + j) * CELL_SIZE, CELL_SIZE, CELL_SIZE);
g.setColor(Color.BLACK);
g.drawRect((currentPieceX + i) * CELL_SIZE, (currentPieceY + j) * CELL_SIZE, CELL_SIZE, CELL_SIZE);
}
}
}
}
public static void main(String[] args) {
SwingUtilities.invokeLater(() -> {
TetrisGame tetrisGame = new TetrisGame();
tetrisGame.setVisible(true);
});
}
}

这是一个简化版的俄罗斯方块游戏实现。该实现使用Java的Swing库创建游戏窗口，通过继承JFrame类实现游戏窗口，通过Timer处理游戏的定时逻辑。

希望这能帮助你开始编写Java俄罗斯方块游戏！
