俄罗斯方块：
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。
笔者相信很多小伙伴都玩过或听说过这个小游戏，今天笔者就带大家走一遍编写流程（写的时间有点久远了，可能有些地方有疏忽，欢迎批评指正）。
俄罗斯方块方块体的设计：
//Blocks.java
public class Blocks {
int[][] t={ {1,1,1,0,0,1,0,0,0,0,0,0,0,0,0,0},
{1,0,0,0,1,1,0,0,1,0,0,0,0,0,0,0},
{0,1,0,0,1,1,1,0,0,0,0,0,0,0,0,0},
{0,1,0,0,1,1,0,0,0,1,0,0,0,0,0,0},
};
int[][] l={ { 1, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
{ 1, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
{ 1, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
{ 1, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 } };
int[][] m={ { 1, 0, 0, 0, 1, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0 },
{ 1, 1, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
{ 1, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0 },
{ 0, 0, 1, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0 } };
int[][] i={
{ 0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0 },
{ 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0 },
{ 0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0 },
{ 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0 } };
}
