目录
一、游戏背景
俄罗斯方块是俄罗斯人发明的。这人叫阿列克谢·帕基特诺夫（Алексей Пажитнов 英文：Alexey Pazhitnov）。俄罗斯方块原名是俄语Тетрис（英语是Tetris），这个名字来源于希腊语tetra，意思是“四”，而游戏的作者最喜欢网球（tennis）。于是，他把两个词tetra和tennis合而为一，命名为Tetris，这也就是俄罗斯方块名字的由来。
规则说明：
由小方块组成的不同形状的板块陆续从屏幕上方落下来，玩家通过调整板块的位置和方向，使它们在屏幕底部拼出完整的一条或几条。这些完整的横条会随即消失，给新落下来的板块腾出空间，与此同时，玩家得到分数奖励。没有被消除掉的方块不断堆积起来，一旦堆到屏幕顶端，玩家便告输，游戏结束。
二、功能实现
开发工具：idea、jdk8
技术汇总：Java基础知识、数组、面向对象、多线程、IO流、Swing。
整体代码分为三个模块：方格模块，七种图形模块，俄罗斯方块主模块。
小方块类：Cell
public class Cell {
// 行
private int row;
// 列
private int col;
private BufferedImage image;
public Cell() {
}
public Cell(int row, int col, BufferedImage image) {
this.row = row;
this.col = col;
this.image = image;
}
public int getRow() {
return row;
}
public void setRow(int row) {
this.row = row;
}
public int getCol() {
return col;
}
public void setCol(int col) {
this.col = col;
}
public BufferedImage getImage() {
return image;
}
public void setImage(BufferedImage image) {
this.image = image;
}
@Override
public String toString() {
return "Cell{" +
"row=" + row +
", col=" + col +
", image=" + image +
'}';
}
@Override
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (!(o instanceof Cell)) {
return false;
}
Cell cell = (Cell) o;
return getRow() == cell.getRow() &&
getCol() == cell.getCol() &&
Objects.equals(getImage(), cell.getImage());
}
@Override
public int hashCode() {
return Objects.hash(getRow(), getCol(), getImage());
}
//左移动一格
public void left(){
col--;
}
//右移动一格
public void right(){
col++;
}
//下移动一格
public void down(){
row++;
}
}
四方格图形的父类：Tetromino
public class Tetromino {

for (Cell cell : cells) {
cell.right();
}
}
//单元格下落
public void moveDrop() {
for (Cell cell : cells) {
cell.down();
}
}
//编写随机生成四方格
public static Tetromino randomOne() {
int num = (int) (Math.random() * 7);
Tetromino tetromino = null;

}
//顺时针旋转的方法

return;
}
//旋转次数+1
count++;
State s = states[count % states.length];
Cell cell = cells[0];
int row = cell.getRow();
int col = cell.getCol();
cells[1].setRow(row + s.row1);

}三、效果展示
游戏开始，方快下落，右边区域展示即将下落的方块图、分数、消除的行数以及游戏切换的状态。
按下空格键，方块瞬间下落， 按下P键游戏暂停，消除一行分数为1（此处由分数池进行控制）
按下C键游戏继续。
按下S键，游戏重新开始。
方块占满，游戏结束，此时可以按下S键重新开始游戏。
