java如何用图形界面显示二维数组俄罗斯方块

Posted 2023-03-25

即已做好俄罗斯方块的下落旋转等，只差将控制台显示的二维数组变成图形或填充色，尝试过用fillrect，但无法如控制台的二维数组一样显示已下落方块。
问题已解决，如有类似问题请在覆盖paint方法里面加个super.paint(g);并注意fill或draw里不要加x,y之类随控制改变而改变的变量

0,2,1,2,2,2,0,3 是 “L" 向右转了90度
0,1,1,1,1,2,1,3 是 “L"向右转了180度
2,1,0,2,1,2,2,2,-1,-1 是 “L"向右转了270度 参考技术B 你会
根据你的描述
建议参考详细的教程

有没有简单的方法，我只想将二维数组的0，1中的1显示到窗口中，其他的都不需要，用双画布好像很麻烦
