俄罗斯方块 (转)

老早以前写的一个俄罗斯方块，不知有没有bug。 /* * 俄罗斯方块(基本功能实现只需400行左右代码) * 程序主框架为: gameInit() * run() -----> paint() & update() * | * |new curBlock <- | need new block? * | | * KListener(moveLeft(), moveRight(), * moveDown(), moveRotate()) * * 显示游戏界面 paint() ,update() * 初始化程序参数,创建游戏线程进入游戏循环{ * 响应用户操作 KListener */ import java.awt.*;
