java实现俄罗斯方块游戏

@Override

public void actionPerformed(ActionEvent e) {

int curLevel = getLevel();

if (!playing && curLevel > 1) {

setLevel(curLevel - 1);

}

}

});

// 退出按钮动作响应

miExit.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

System.exit(0);

}

});

}

3、添加事件监听

/*

• 添加事件监听

*/

/*

• 开始游戏

*/

btPlay.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent ae) {

// TODO Auto-generated method stub

game.playGame();

}

});

/*

• 暂停游戏

*/

btPause.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent ae) {

// TODO Auto-generated method stub

if (btPause.getText().equals(“暂停”)) {

game.pauseGame();

} else {

game.resumeGame();

}

}

});

/*

• 停止游戏

*/

btStop.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent ae) {

// TODO Auto-generated method stub

game.stopGame();

}

});

/*

• 升高难度

*/

btTurnLevelUp.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent ae) {

// TODO Auto-generated method stub

try {

int level = Integer.parseInt(tfLevel.getText());

if (level < RussiaBlocksGame.MAX_LEVEL) {

tfLevel.setText(“” + (level + 1));

}

} catch (NumberFormatException e) {

// TODO: handle exception

requestFocus();

}

}

});

/*

• 降低游戏难度

*/

btTurnLevelDown.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent ae) {

// TODO Auto-generated method stub

try {

int level = Integer.parseInt(tfLevel.getText());

if (level > 1) {

tfLevel.setText(“” + (level - 1));

}

} catch (NumberFormatException e) {

// TODO: handle exception

requestFocus();

}

}

});

/*

• 主要用于解决Jframe窗口大小变化时，里面的组件的位置也会自适应的移动。

*/

addComponentListener(new ComponentAdapter() {

public void componentResized(ComponentEvent ce) {

plTipBlock.fanning();

}

});

4、创建方块

public class ErsBox implements Cloneable {

private boolean isColor;

private Dimension size = new Dimension(); // Dimension类封装单个对象中组件的宽度和高度(精确到整数)

/*

• 方格类构造函数 isColor是不是用前景色为此方格着色，true前景色，false背景色

*/

public ErsBox(boolean isColor) {

// TODO Auto-generated constructor stub

this.isColor = isColor;

}

/*

• 设置方格的颜色 true前景色，false背景色

*/

public void setColor(boolean isColor) {

// TODO Auto-generated method stub

this.
