Java怎样实现经典俄罗斯方块游戏(java,开发技术)

前言

俄罗斯方块是一个最初由阿列克谢帕吉特诺夫在苏联设计和编程的益智类视频游戏。

《俄罗斯方块》的基本规则是移动、旋转和摆放游戏自动输出的各种方块，使之排列成完整的一行或多行并且消除得分。

用java语言实现，采用了swing技术进行了界面化处理，设计思路用了面向对象思想。

主要需求

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。

主要设计

1、用键盘操作,"←"左移一格；"→"右移一格；"↑"旋转方块；↓ 方块丢下（方块下落到底）

2、一旦堆到屏幕顶端，游戏结束

3、设计不同的方块

4、设计方块下落的速度

5、设计分数系统

Java的优点是什么

1. 简单，只需理解基本的概念，就可以编写适合于各种情况的应用程序；2. 面向对象；3. 分布性，Java是面向网络的语言；4. 鲁棒性，java提供自动垃圾收集来进行内存管理，防止程序员在管理内存时容易产生的错误。；5. 安全性，用于网络、分布环境下的Java必须防止病毒的入侵。6. 体系结构中立，只要安装了Java运行时系统，就可在任意处理器上运行。7. 可移植性，Java可以方便地移植到网络上的不同机器。8.解释执行，Java解释器直接对Java字节码进行解释执行。
