Java实现俄罗斯方块小游戏。(附完整源代码)_Java

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++;
}
}
