java实现简单的俄罗斯方块

java实现简单的俄罗斯方块

本文实例为大家分享了java实现简单俄罗斯方块的具体代码，供大家参考，具体内容如下

结合网上的资料刚做完课程设计，具体代码如下：

public class TetrisPanel extends JPanel{

private final int[][] map = new int[13][23];// map[列号][行号]。真正的方块区是:21行*10列。边框(2列，1行)

// 方块的形状：

// 第一维代表方块类型(包括7种:S、Z、L、J、I、O、T)

// 第二`在这里插入代码片`维代表旋转次数

// 第三四维代表方块矩阵

// shapes[type][turnState][i] i--> block[i/4][i%4]

int[][][] shapes = new int[][][] {

/*
