俄羅斯方塊游戲是一個(gè)上手簡單，老少皆宜的游戲，它的基本規(guī)則是移動、旋轉(zhuǎn)和擺放游戲自動產(chǎn)生的各種方塊，使之排列成完整的一行或多行并且消除得分。

你能學(xué)到什么？

通過本文的閱讀，讀者可以對Swing版俄羅斯方塊游戲的本身，對游戲中的關(guān)鍵點(diǎn)，如圖形變換、鍵盤事件處理、游戲進(jìn)度保存、滿行和消行等都會有較好的理解。

游戲界面

界面組成

游戲界面有四個(gè)部分組成：

游戲面板區(qū)　－－　游戲主面板

下一個(gè)圖形預(yù)覽區(qū)　－－　呈現(xiàn)下一個(gè)圖形

分?jǐn)?shù)顯示區(qū)　－－　顯示目前的得分

菜單欄　－－　具備幫助、游戲設(shè)置、進(jìn)度保存等功能

圖形選擇

一般來講，一個(gè)圖形有四個(gè)點(diǎn)，可以表示出常用的“一字型”，“T字型”，“Z字型”以及“L字型”方塊。

如果將四個(gè)點(diǎn)的一個(gè)或者多個(gè)重疊，或者不采用常用的“一字型”，“T字型”，“Z字型”以及“L字型”方塊，那么可以演變出更多的圖形出來。如果想要更加豐富和復(fù)雜的圖形，可以使用更多的點(diǎn)去表示想要的圖形。

四個(gè)點(diǎn)組成的圖形有如下幾種：

常規(guī)圖形

?

?

?

?

非重合的常規(guī)圖形

如果將四個(gè)點(diǎn)中的一個(gè)或者多個(gè)點(diǎn)重合，就可以有如下幾種類型的圖形：

無重合點(diǎn)的不常規(guī)圖

如果四個(gè)點(diǎn)不重合，還可以有如下幾種比較詭異的圖形，可以為游戲增加難度。

圖形對象類表示

格子類( Grid.java )?，俄羅斯方塊游戲中的圖形由四個(gè)格子組成。每個(gè)格子類有下x , y兩個(gè)坐標(biāo)位置，顏色，以及格子圖形繪制方法等。

如：

圖形抽象類 ( AbstractRussiaSquare .java?)。抽象類包含一些公用的屬性（如：每個(gè)圖形由四個(gè)方塊組成）、公用的方法（如向左移動、向右移動）、抽象方法（如圖形變換需要子類實(shí)現(xiàn)細(xì)節(jié)）。

如：

每個(gè)子類，只要繼承了該抽象父類即可擁有公有的方法和屬性，實(shí)現(xiàn)父類定義的抽象方法就可以擁有自身的實(shí)現(xiàn)細(xì)節(jié)。

關(guān)鍵點(diǎn)

圖形變換

圖形變換或者圖形旋轉(zhuǎn)是俄羅斯方塊游戲中比較關(guān)鍵的一個(gè)部分。

圖形變換的思想？

因?yàn)橐粋€(gè)圖形有四個(gè)點(diǎn)來表示，可以先確定其中的一個(gè)點(diǎn)的變換位置，然后其它的三個(gè)點(diǎn)根據(jù)這個(gè)確定的基點(diǎn)進(jìn)行位置調(diào)整就可以了。?
?

比如，

以一字型的圖形為例，只要第二號格子為固定點(diǎn)，相繼算出其它格子的位置即可。

package my.games.russia.model;import java.util.Random;/*** 一字型* @author wangmengjun**/ public class RussiaSquare_2 extends AbstractRussiaSquare {private static final long serialVersionUID = -4746450405460864752L;public RussiaSquare_2() {initGrids();}/* (non-Javadoc)* @see my.games.russia.model.AbstractRussiaSquare#changeState(int[][])*/@Overridepublic void changeState(int[][] flags) {int fixedXLocation = grids[1].getX();int fixedYLocation = grids[1].getY();switch (state) {case 0:/*** 橫向到豎直方向轉(zhuǎn)換*//*** 第二個(gè)點(diǎn)保持不變*/xLocations[1] = fixedXLocation;yLocations[1] = fixedYLocation;xLocations[0] = fixedXLocation;yLocations[0] = fixedYLocation - 1;xLocations[2] = fixedXLocation;yLocations[2] = fixedYLocation + 1;xLocations[3] = fixedXLocation;yLocations[3] = fixedYLocation + 2;isAllowChangeState(flags, 2);break;case 1:xLocations[1] = fixedXLocation;yLocations[1] = fixedYLocation;/*** 豎直到橫向轉(zhuǎn)換*/xLocations[0] = fixedXLocation - 1;yLocations[0] = fixedYLocation;xLocations[2] = fixedXLocation + 1;yLocations[2] = fixedYLocation;xLocations[3] = fixedXLocation + 2;yLocations[3] = fixedYLocation;isAllowChangeState(flags, 2);break;default:break;}}/* (non-Javadoc)* @see my.games.russia.model.AbstractRussiaSquare#initGrids()*/@Overridepublic void initGrids() {state = new Random().nextInt(2);switch (state) {case 0:/*** 豎直*/grids[0].setX(9);grids[0].setY(0);grids[1].setX(grids[0].getX());grids[1].setY(grids[0].getY() + 1);grids[2].setX(grids[0].getX());grids[2].setY(grids[0].getY() + 2);grids[3].setX(grids[0].getX());grids[3].setY(grids[0].getY() + 3);break;case 1:/*** 橫向*/grids[0].setX(8);grids[0].setY(0);grids[1].setX(grids[0].getX() + 1);grids[1].setY(grids[0].getY());grids[2].setX(grids[0].getX() + 2);grids[2].setY(grids[0].getY());grids[3].setX(grids[0].getX() + 3);grids[3].setY(grids[0].getY());break;default:break;}}}

采用類似的方法，可以寫出T字形的方塊轉(zhuǎn)換：

package my.games.russia.model;import java.util.Random;/*** T字型方塊* @author wangmengjun**/ public class RussiaSquare_3 extends AbstractRussiaSquare {private static final long serialVersionUID = -8336206016924545562L;public RussiaSquare_3() {initGrids();}/* (non-Javadoc)* @see my.games.russia.model.AbstractRussiaSquare#changeState(int[][])*/@Overridepublic void changeState(int[][] flags) {switch (state) {case 0:xLocations[0] = grids[0].getX();yLocations[0] = grids[0].getY();xLocations[1] = xLocations[0];yLocations[1] = yLocations[0] + 1;xLocations[2] = xLocations[0] + 1;yLocations[2] = yLocations[0] + 1;xLocations[3] = xLocations[0];yLocations[3] = yLocations[0] + 2;isAllowChangeState(flags, 4);break;case 1:xLocations[0] = grids[0].getX() - 1;yLocations[0] = grids[0].getY() + 1;xLocations[1] = xLocations[0] + 1;yLocations[1] = yLocations[0];xLocations[2] = xLocations[0] + 2;yLocations[2] = yLocations[0];xLocations[3] = xLocations[0] + 1;yLocations[3] = yLocations[0] + 1;isAllowChangeState(flags, 4);break;case 2:xLocations[0] = grids[0].getX() + 1;yLocations[0] = grids[0].getY() - 1;xLocations[1] = xLocations[0] - 1;yLocations[1] = yLocations[0] + 1;xLocations[2] = xLocations[0];yLocations[2] = yLocations[0] + 1;xLocations[3] = xLocations[0];yLocations[3] = yLocations[0] + 2;isAllowChangeState(flags, 4);break;case 3:xLocations[0] = grids[0].getX();yLocations[0] = grids[0].getY();xLocations[1] = xLocations[0] - 1;yLocations[1] = yLocations[0] + 1;xLocations[2] = xLocations[0];yLocations[2] = yLocations[0] + 1;xLocations[3] = xLocations[0] + 1;yLocations[3] = yLocations[0] + 1;isAllowChangeState(flags, 4);break;default:break;}}/* (non-Javadoc)* @see my.games.russia.model.AbstractRussiaSquare#initGrids()*/@Overridepublic void initGrids() {state = new Random().nextInt(4);switch (state) {case 0:grids[0].setX(9);grids[0].setY(0);grids[1].setX(grids[0].getX() - 1);grids[1].setY(grids[0].getY() + 1);grids[2].setX(grids[0].getX());grids[2].setY(grids[0].getY() + 1);grids[3].setX(grids[0].getX() + 1);grids[3].setY(grids[0].getY() + 1);break;case 1:grids[0].setX(9);grids[0].setY(0);grids[1].setX(grids[0].getX());grids[1].setY(grids[0].getY() + 1);grids[2].setX(grids[0].getX() + 1);grids[2].setY(grids[0].getY() + 1);grids[3].setX(grids[0].getX());grids[3].setY(grids[0].getY() + 2);break;case 2:grids[0].setX(9);grids[0].setY(0);grids[1].setX(grids[0].getX() + 1);grids[1].setY(grids[0].getY());grids[2].setX(grids[0].getX() + 2);grids[2].setY(grids[0].getY());grids[3].setX(grids[0].getX() + 1);grids[3].setY(grids[0].getY() + 1);break;case 3:grids[0].setX(9);grids[0].setY(0);grids[1].setX(grids[0].getX() - 1);grids[1].setY(grids[0].getY() + 1);grids[2].setX(grids[0].getX());grids[2].setY(grids[0].getY() + 1);grids[3].setX(grids[0].getX());grids[3].setY(grids[0].getY() + 2);break;default:break;}}}

鍵盤事件的處理?

鍵盤事件主要有如下幾個(gè)部分

向左

向右

向下

按向上鍵變換圖形

按空格鍵直接到最底部

向左

/*** 往左移動* */public void moveLeft(int[][] flags) {if (!alive) {return;}/*** 將現(xiàn)有的點(diǎn)賦值到xLocation和yLocation上去*/for (int i = 0; i < grids.length; i++) {xLocations[i] = grids[i].getX() - 1;yLocations[i] = grids[i].getY();}if (xLocations[0] >= RussiaGameConstant.LEFT && flags[xLocations[0]][yLocations[0]] == 0&& xLocations[1] >= RussiaGameConstant.LEFT&& flags[xLocations[1]][yLocations[1]] == 0&& xLocations[2] >= RussiaGameConstant.LEFT&& flags[xLocations[2]][yLocations[2]] == 0&& xLocations[3] >= RussiaGameConstant.LEFT&& flags[xLocations[3]][yLocations[3]] == 0) {for (int i = 0; i < grids.length; i++) {grids[i].setX(xLocations[i]);}}}

向右以及向下都和向左操作類似。

向右

/*** 往右移動*/public void moveRight(int flags[][]) {if (!alive) {return;}for (int i = 0; i < grids.length; i++) {xLocations[i] = grids[i].getX() + 1;yLocations[i] = grids[i].getY();}if (xLocations[0] <= RussiaGameConstant.RIGHT && flags[xLocations[0]][yLocations[0]] == 0&& xLocations[1] <= RussiaGameConstant.RIGHT&& flags[xLocations[1]][yLocations[1]] == 0&& xLocations[2] <= RussiaGameConstant.RIGHT&& flags[xLocations[2]][yLocations[2]] == 0&& xLocations[3] <= RussiaGameConstant.RIGHT&& flags[xLocations[3]][yLocations[3]] == 0) {for (int i = 0; i < grids.length; i++) {grids[i].setX(xLocations[i]);}}}

向下

/*** 往下移動*/public void moveDown(int[][] flags) {for (int i = 0; i < grids.length; i++) {xLocations[i] = grids[i].getX();yLocations[i] = grids[i].getY() + 1;}if (yLocations[0] <= RussiaGameConstant.DOWN && flags[xLocations[0]][yLocations[0]] == 0&& yLocations[1] <= RussiaGameConstant.DOWN&& flags[xLocations[1]][yLocations[1]] == 0&& yLocations[2] <= RussiaGameConstant.DOWN&& flags[xLocations[2]][yLocations[2]] == 0&& yLocations[3] <= RussiaGameConstant.DOWN&& flags[xLocations[3]][yLocations[3]] == 0) {for (int i = 0; i < grids.length; i++) {grids[i].setY(yLocations[i]);;}} else {alive = false;}}

變換圖形

每個(gè)圖形，或有一種變換，或者有2種或者有四種變換，可以根據(jù)圖形的特性進(jìn)行處理。?

比如，將“T字型”圖型按照順時(shí)針旋轉(zhuǎn)，擁有四種變換，創(chuàng)建對象的時(shí)候已經(jīng)確定了state是多少（state確定初始的位置是哪里），此后的變換只要對state加1并對4求余就可以知道怎么變換。?

/* (non-Javadoc)* @see my.games.russia.model.AbstractRussiaSquare#changeState(int[][])*/@Overridepublic void changeState(int[][] flags) {switch (state) {case 0:xLocations[0] = grids[0].getX();yLocations[0] = grids[0].getY();xLocations[1] = xLocations[0];yLocations[1] = yLocations[0] + 1;xLocations[2] = xLocations[0] + 1;yLocations[2] = yLocations[0] + 1;xLocations[3] = xLocations[0];yLocations[3] = yLocations[0] + 2;isAllowChangeState(flags, 4);break;case 1:xLocations[0] = grids[0].getX() - 1;yLocations[0] = grids[0].getY() + 1;xLocations[1] = xLocations[0] + 1;yLocations[1] = yLocations[0];xLocations[2] = xLocations[0] + 2;yLocations[2] = yLocations[0];xLocations[3] = xLocations[0] + 1;yLocations[3] = yLocations[0] + 1;isAllowChangeState(flags, 4);break;case 2:xLocations[0] = grids[0].getX() + 1;yLocations[0] = grids[0].getY() - 1;xLocations[1] = xLocations[0] - 1;yLocations[1] = yLocations[0] + 1;xLocations[2] = xLocations[0];yLocations[2] = yLocations[0] + 1;xLocations[3] = xLocations[0];yLocations[3] = yLocations[0] + 2;isAllowChangeState(flags, 4);break;case 3:xLocations[0] = grids[0].getX();yLocations[0] = grids[0].getY();xLocations[1] = xLocations[0] - 1;yLocations[1] = yLocations[0] + 1;xLocations[2] = xLocations[0];yLocations[2] = yLocations[0] + 1;xLocations[3] = xLocations[0] + 1;yLocations[3] = yLocations[0] + 1;isAllowChangeState(flags, 4);break;default:break;}}

一鍵到底

按下空格鍵一直向下的操作，其實(shí)就是在可以動的范圍下，一直調(diào)用moveDown()方法

case KeyEvent.VK_SPACE:while (sr1.isAlive()) {sr1.moveDown(flag);}

針對鍵盤的操作，大家可以定義一個(gè)內(nèi)部的事件處理器。

private class KeyHandler implements KeyListener {public void keyPressed(KeyEvent event) {if (!gameState.isRunState()) {return;}int keyCode = event.getKeyCode();switch (keyCode) {case KeyEvent.VK_LEFT:sr1.moveLeft(flag);break;case KeyEvent.VK_RIGHT:sr1.moveRight(flag);break;case KeyEvent.VK_UP:sr1.changeState(flag);break;case KeyEvent.VK_DOWN:sr1.moveDown(flag);break;case KeyEvent.VK_SPACE:while (sr1.isAlive()) {sr1.moveDown(flag);}default:break;}repaint();}public void keyReleased(KeyEvent event) {}public void keyTyped(KeyEvent event) {}}

然后，在游戲Panel創(chuàng)建的時(shí)候，添加上去即可。

addKeyListener(new KeyHandler());

滿行及其消行操作?

用一個(gè)二維數(shù)組記錄當(dāng)前屏幕上的方塊狀態(tài)，0表示沒有方塊，1表示有方塊。

滿行條件？

滿行的判斷就歸結(jié)到某一行1的個(gè)數(shù)是否等于該行列的總數(shù)，如果是就滿足滿行條件。?

當(dāng)有滿行情況出現(xiàn)的時(shí)候，需要進(jìn)行消除和計(jì)分操作。?

如何消行？
?

消除行的一個(gè)做法就是將該行以上的行通通往下移，移動之后在將第一行的flag全部置為0。

for (int i = RussiaGameConstant.UP; i <= RussiaGameConstant.DOWN; i++) {int count = 0;for (int j = RussiaGameConstant.LEFT; j <= RussiaGameConstant.RIGHT; j++) {count += flag[j][i];}/** flag[i][j] =1 表示這個(gè)位置有小方塊，如果一行的位置都有小方塊，那么滿行的個(gè)數(shù)num加1.* 并且消除行。*/if (count == RussiaGameConstant.GRID_COLUMN_NUMBER) {num++;/*** 消除行操作。*/for (int m = i; m > RussiaGameConstant.UP; m--) {for (int n = RussiaGameConstant.LEFT; n <= RussiaGameConstant.RIGHT; n++) {flag[n][m] = flag[n][m - 1];color[n][m] = color[n][m - 1];}}/** 重新將第一行的flag[s][0]置為0*/for (int s = RussiaGameConstant.LEFT; s <= RussiaGameConstant.RIGHT; s++) {flag[s][RussiaGameConstant.UP] = 0;}}} /*** @param num* 方塊滿行的個(gè)數(shù)*/private void calculateScore(int num) {switch (num) {case 1:score += 10;break;case 2:score += 20;break;case 3:score += 50;break;case 4:score += 100;break;default:break;}}

游戲結(jié)束判斷?

俄羅斯方塊游戲結(jié)束的判斷其實(shí)很簡單，只要判斷第一行的標(biāo)記位是否有1即可。

/*** 如果是top touched 則執(zhí)行Game Over的相關(guān)操作* */private void judgeGameOver() {if (isTopTouched()) {gameState = GameState.OVER;writeScore();int result = JOptionPane.showConfirmDialog(frame, "Game over! Continue?", "俄羅斯方塊",JOptionPane.YES_NO_OPTION);if (result == JOptionPane.YES_OPTION) {for (int i = RussiaGameConstant.LEFT; i <= RussiaGameConstant.RIGHT; i++) {for (int j = RussiaGameConstant.UP; j <= RussiaGameConstant.DOWN; j++) {flag[i][j] = 0;}}gameState = GameState.RUN;score = 0;timer.start();} else {System.exit(0);}}} private boolean isTopTouched() {for (int i = RussiaGameConstant.LEFT; i <= RussiaGameConstant.RIGHT; i++) {if (flag[i][RussiaGameConstant.UP] == 1) {return true;}}return false;}

游戲進(jìn)度存儲和加載?

?游戲進(jìn)度的保存和加載功能是通過序列化和反序列化來完成的。?

如何保存游戲進(jìn)度？

通過序列化的方式將當(dāng)前游戲運(yùn)行狀態(tài)中用到的一些重要對象屬性序列化到文件中加以保存，從而達(dá)到記錄當(dāng)前游戲狀態(tài)的效果。?

如何載入游戲進(jìn)度？

通過反序列化的方式將序列化后的對象讀取出來，從而達(dá)到恢復(fù)之前游戲保存時(shí)的狀態(tài)的效果。用戶可以在此基礎(chǔ)上繼續(xù)進(jìn)行游戲。?

步驟

（一）編寫保存游戲進(jìn)度、加載游戲進(jìn)度的事件監(jiān)聽器

private class LoadAction implements ActionListener {public void actionPerformed(ActionEvent event) {FileDialog dialog = new FileDialog(RussiaGameFrame.this, "Open",FileDialog.LOAD);dialog.setVisible(true);String dir = dialog.getDirectory();String fileName = dialog.getFile();String filePath = dir + fileName;if (fileName != null && fileName.trim().length() != 0) {File file = new File(filePath);panel.readSelfFromFile(file);startMI.setEnabled(false);pauseMI.setEnabled(true);} else {JOptionPane.showConfirmDialog(RussiaGameFrame.this,"文件名為空\n裝載游戲進(jìn)度失敗", "俄羅斯方塊", JOptionPane.DEFAULT_OPTION);}}}private class SaveAction implements ActionListener {public void actionPerformed(ActionEvent event) {if (panel.gameState == GameState.INITIALIZE) {JOptionPane.showConfirmDialog(RussiaGameFrame.this,"游戲沒有運(yùn)行\(zhòng)n不能保存游戲進(jìn)度", "俄羅斯方塊",JOptionPane.DEFAULT_OPTION);return;}FileDialog dialog = new FileDialog(RussiaGameFrame.this, "Save",FileDialog.SAVE);dialog.setVisible(true);String dir = dialog.getDirectory();String fileName = dialog.getFile();String filePath = dir + fileName;if (fileName != null && fileName.trim().length() != 0) {File file = new File(filePath);panel.writeSelfToFile(file);} else {JOptionPane.showConfirmDialog(RussiaGameFrame.this,"文件名為空\n保存游戲進(jìn)度失敗", "俄羅斯方塊", JOptionPane.DEFAULT_OPTION);}}}

（二）添加用于保存和加載功能的MenuItem, 并為它們添加ActionListenser?

private JMenuItem loadMI = new JMenuItem("Open");public JMenuItem saveMI = new JMenuItem("Save"); setMenu.add(loadMI);setMenu.add(saveMI); loadMI.addActionListener(new LoadAction()); saveMI.addActionListener(new SaveAction());

（三）編寫具體的業(yè)務(wù)邏輯

public void writeSelfToFile(File file) {try {FileOutputStream fileStream = new FileOutputStream(file);ObjectOutputStream objectStream = new ObjectOutputStream(fileStream);objectStream.writeObject(flag);objectStream.writeObject(color);objectStream.writeObject(sr1);objectStream.writeObject(sr2);objectStream.writeObject(new Integer(score));objectStream.close();fileStream.close();JOptionPane.showConfirmDialog(frame, "保存游戲進(jìn)度成功", "俄羅斯方塊", JOptionPane.DEFAULT_OPTION);} catch (Exception e) {JOptionPane.showConfirmDialog(frame, e.toString() + "\n保存游戲進(jìn)度失敗", "俄羅斯方塊",JOptionPane.DEFAULT_OPTION);}}public void readSelfFromFile(File file) {try {int[][] f;AbstractRussiaSquare s1, s2;Integer integer;Color[][] c;FileInputStream fileStream = new FileInputStream(file);ObjectInputStream objectStream = new ObjectInputStream(fileStream);f = (int[][]) objectStream.readObject();c = (Color[][]) objectStream.readObject();s1 = (AbstractRussiaSquare) objectStream.readObject();s2 = (AbstractRussiaSquare) objectStream.readObject();integer = (Integer) objectStream.readObject();objectStream.close();fileStream.close();if (f != null && c != null && s1 != null && s2 != null && integer != null) {flag = f;color = c;sr1 = s1;sr2 = s2;score = integer.intValue();gameState = GameState.RUN;frame.saveMI.setEnabled(true);if (!timer.isRunning()) {timer.start();}repaint();JOptionPane.showConfirmDialog(frame, "裝載游戲進(jìn)度成功", "俄羅斯方塊",JOptionPane.DEFAULT_OPTION);}} catch (Exception e) {JOptionPane.showConfirmDialog(frame, e.toString() + "\n裝載游戲進(jìn)度失敗", "俄羅斯方塊",JOptionPane.DEFAULT_OPTION);}}

游戲玩家得分排行榜?

得分排行榜上列出Top 10的記錄信息，包括玩家名稱，得分和名次。?

該功能可以通過如下幾個(gè)步驟完成：?

步驟

（一）創(chuàng)建游戲記錄類和比較器

package my.games.russia.model;import java.io.Serializable;/*** 記錄玩家的信息* @author wangmengjun**/ public class Record implements Serializable {private static final long serialVersionUID = 9143467974370981697L;/**玩家姓名*/private String player = null;/**玩家得分*/private int score = 0;public Record(String player, int score) {this.player = player;this.score = score;}/*** @return the player*/public String getPlayer() {return player;}/*** @param player the player to set*/public void setPlayer(String player) {this.player = player;}/*** @return the score*/public int getScore() {return score;}/*** @param score the score to set*/public void setScore(int score) {this.score = score;}}

先通過分?jǐn)?shù)比較，如果分?jǐn)?shù)一致，則比較玩家名字。

package my.games.russia.compare;import java.util.Comparator;import my.games.russia.model.Record;/*** 俄羅斯記錄的比較器* @author wangmengjun**/ public class RecordComparator implements Comparator<Record> {public int compare(Record o1, Record o2) {Record r1 = (Record) o1;Record r2 = (Record) o2;int compareScore = compareScore(r1, r2);return (0 == compareScore) ? compareScore : compareName(r1, r2);}private int compareScore(Record r1, Record r2) {return r2.getScore() - r1.getScore();}private int compareName(Record r1, Record r2) {return r1.getPlayer().compareTo(r2.getPlayer());}}

（二）完成游戲結(jié)束后對記錄文件更新的操作。?

private void writeScore() {if (score == 0) {return;}File file = new File("file.dat");RussiaGameRecords records = new ReadRecord().readRecordsFromFile(file);if (records == null || records.isEmpty() || !records.isFull()|| (records.getLastAvailableRecord().getScore() < score && records.isFull())) {String playerName = JOptionPane.showInputDialog("Please input your name");if (playerName == null || playerName.length() == 0) {playerName = "無名英雄";}Record record = new Record(playerName, score);records.addRecordToTopTen(record);new WriteRecord().writeRecordToFile(records, file);}}

（三）完成點(diǎn)擊Record相關(guān)的MenuItem，讀取記錄信息，并用ScrollPane展示出來。?

package my.games.russia.ui;import java.io.File;import javax.swing.JScrollPane; import javax.swing.JTable; import my.games.russia.model.Record; import my.games.russia.model.RussiaGameRecords;/*** * @author wangmengjun**/ public class ReadScrollPane {public JScrollPane getReadScrollPane(RussiaGameRecords records, File recordFile) {Object[][] data = new Object[records.getNumberInRecord()][3];for (int i = 0; i < records.getNumberInRecord(); i++) {Record record = records.getRecords()[i];data[i][0] = String.valueOf(i + 1);data[i][1] = record.getPlayer();data[i][2] = String.valueOf(record.getScore());}Object[] columnNames = new Object[3];columnNames[0] = "ID";columnNames[1] = "Name";columnNames[2] = "Score";JTable table = new JTable(data, columnNames);table.setAutoResizeMode(JTable.AUTO_RESIZE_ALL_COLUMNS);JScrollPane pane = new JScrollPane(table);return pane;}}

隨機(jī)產(chǎn)生方塊

為了游戲更具隨機(jī)性，隨機(jī)產(chǎn)生方塊主要包含兩個(gè)部分的隨機(jī)性。

方塊圖形產(chǎn)生的隨機(jī)性

編寫一個(gè)工廠類，隨機(jī)產(chǎn)生方塊：如產(chǎn)生一字型的方塊、T字形的方塊等。

package my.games.russia.util;import java.util.Random;import my.games.russia.model.AbstractRussiaSquare; import my.games.russia.model.RussiaSquare_1; import my.games.russia.model.RussiaSquare_2; import my.games.russia.model.RussiaSquare_3;/*** * @author wangmengjun**/ public class RussiaSquareFactory {private static final int TOTAL_RUSSIA_SQUARE_COUNT = 3;public static AbstractRussiaSquare generateNextRussiaSquareByRandom() {AbstractRussiaSquare rs = null;int index = new Random().nextInt(TOTAL_RUSSIA_SQUARE_COUNT);switch (index) {case 0:rs = new RussiaSquare_1();break;case 1:rs = new RussiaSquare_2();break;case 2:rs = new RussiaSquare_3();break;default:rs = new RussiaSquare_1();break;}return rs;} }

方塊初始化的隨機(jī)性

每個(gè)圖形通過旋轉(zhuǎn)，都可以有不一樣的初始化形態(tài)。比如T字形的方塊就可以有四種形態(tài)，初始化的時(shí)候，也就有四種初始狀態(tài)。如下是T字形方塊的初始化：

/* (non-Javadoc)* @see my.games.russia.model.AbstractRussiaSquare#initGrids()*/@Overridepublic void initGrids() {state = new Random().nextInt(4);switch (state) {case 0:grids[0].setX(9);grids[0].setY(0);grids[1].setX(grids[0].getX() - 1);grids[1].setY(grids[0].getY() + 1);grids[2].setX(grids[0].getX());grids[2].setY(grids[0].getY() + 1);grids[3].setX(grids[0].getX() + 1);grids[3].setY(grids[0].getY() + 1);break;case 1:grids[0].setX(9);grids[0].setY(0);grids[1].setX(grids[0].getX());grids[1].setY(grids[0].getY() + 1);grids[2].setX(grids[0].getX() + 1);grids[2].setY(grids[0].getY() + 1);grids[3].setX(grids[0].getX());grids[3].setY(grids[0].getY() + 2);break;case 2:grids[0].setX(9);grids[0].setY(0);grids[1].setX(grids[0].getX() + 1);grids[1].setY(grids[0].getY());grids[2].setX(grids[0].getX() + 2);grids[2].setY(grids[0].getY());grids[3].setX(grids[0].getX() + 1);grids[3].setY(grids[0].getY() + 1);break;case 3:grids[0].setX(9);grids[0].setY(0);grids[1].setX(grids[0].getX() - 1);grids[1].setY(grids[0].getY() + 1);grids[2].setX(grids[0].getX());grids[2].setY(grids[0].getY() + 1);grids[3].setX(grids[0].getX());grids[3].setY(grids[0].getY() + 2);break;default:break;}}

方塊下降和速度改變

方塊下降可以采用Timer來控制。如：

public Timer timer;public TimerAction timerAction; timerAction = new TimerAction();timer = new Timer(1000, timerAction);

TimeAction類執(zhí)行相關(guān)的邏輯行為，如：

private class TimerAction implements ActionListener, Serializable {private static final long serialVersionUID = -6117702515382009989L;public void actionPerformed(ActionEvent event) {if (!gameState.isRunState()) {return;}//滿行的個(gè)數(shù)int num = 0;sr1.moveDown(flag);if (!sr1.isAlive()) {for (int i = 0; i < 4; i++) {Grid[] grids = sr1.getGrids();flag[grids[i].getX()][grids[i].getY()] = 1;color[grids[i].getX()][grids[i].getY()] = sr1.getColor();}judgeGameOver();for (int i = RussiaGameConstant.UP; i <= RussiaGameConstant.DOWN; i++) {int count = 0;for (int j = RussiaGameConstant.LEFT; j <= RussiaGameConstant.RIGHT; j++) {count += flag[j][i];}/** flag[i][j] =1 表示這個(gè)位置有小方塊，如果一行的位置都有小方塊，那么滿行的個(gè)數(shù)num加1.* 并且消除行。*/if (count == RussiaGameConstant.GRID_COLUMN_NUMBER) {num++;/*** 消除行操作。*/for (int m = i; m > RussiaGameConstant.UP; m--) {for (int n = RussiaGameConstant.LEFT; n <= RussiaGameConstant.RIGHT; n++) {flag[n][m] = flag[n][m - 1];color[n][m] = color[n][m - 1];}}/** 重新將第一行的flag[s][0]置為0*/for (int s = RussiaGameConstant.LEFT; s <= RussiaGameConstant.RIGHT; s++) {flag[s][RussiaGameConstant.UP] = 0;}}}/** 將下一個(gè)圖形作為當(dāng)前運(yùn)動的圖形，并隨機(jī)產(chǎn)生下一個(gè)圖形。*/sr1 = sr2;sr2 = RussiaSquareFactory.generateNextRussiaSquareByRandom();}// 計(jì)算分?jǐn)?shù)calculateScore(num);repaint();}}

小結(jié)

通過如上的步驟，一個(gè)單機(jī)版的Swing游戲就實(shí)現(xiàn)了，本文描述和實(shí)現(xiàn)了三種方塊類型的旋轉(zhuǎn)。

田字形

一字型

T字形

大家可以參考上述的變形方法完成其他類型的變化，如L型， Z字形。

游戲效果如下：
