点击此处下载 ourdev_551278.txt(文件大小:20K) (原文件名:els.txt) 不错嘛,要是有详细注释就好了。。。 可以横显示吗 本程序不可以横着显示,但是可以改,很简单的事情,我刚开始的时候是横着方向下落方块的,后来才改为垂直下落方块的。
方法是:
描点的方式改一下,检查冲突也要改,显示数字和字母所取点方式也要改。 mark 厉害mark mark 楼主,向你学习!!!!! 回复【5楼】lzf713

(原文件名:横向跑俄罗斯方块.JPG) 强帖留名 留下日后以定看!这个东西想把它弄出来! biao ji MARK 参考下。谢谢分享 mark....... mark 谢谢楼主分享! 牛人 hehe,攒 MARK 强。手上有类似组合的实物,可以耍耍。。 mark!!! 学习的好文章!!!
谢谢楼主无私奉献源码 标记一下 学习啦…刚做完贪吃蛇…最近和游戏干上了… ding 真帅~~~学习了 mark
good Mark 好玩~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 学习中 mark一下 楼主真厉害 确实能用,楼主确实很有实力啊 顶一下,让更多人知道~ 学习中 好。。看看。。。站在 顶顶! mark 回复【楼主位】lzf713

佩服! 太强了楼主 mark mark 有注释就好了 顶 MARK! mark 不错 mark mark 等有空了, 咱也弄一个玩玩 可惜,这个程序做的太繁琐了。。。 回复【54楼】heyunqingfeng

高人那!
也许void lcdPutPix(uchar x, uchar y,uchar flag) 这个函数比较复杂,但是这样做的目的就是想加快画点速度。这个程序仿真是可行的,但是用实物就不行了,出现画屏情况。问题就在void lcdPutPix(uchar x, uchar y,uchar flag) 这个函数,原因是画点过程是这样的:根据将要在X,Y位置所在的单元数据读取回来(要读取三个单元),然后修改,再回写。问题出现在读取单元数据,延迟不够。
原来:
lcdSetColumn(i);
ea=EA;
EA=0;
EN=0;
LCD=0xff;
RS=1;
RW=1;
EN=1;
EN=0;
EN=1;
dat=LCD;
EN=0;
if(flag==1)
dat|=bitmask;
else
dat&=~bitmask;
lcdSetColumn(i);
EN=0;
RW=0;
RS=1;
LCD=dat;
EN=1;
EN=1;
EN=0;
EA=ea;
}
可以改为:
lcdSetColumn(i);
ea=EA;
EA=0;
EN=0;
LCD=0xff;
RS=1;
RW=1;
EN=1;
EN=0;
EN=0;//增加延迟
EN=1; //增加延迟
EN=1; //增加延迟
EN=1;
dat=LCD;
EN=0;
if(flag==1)
dat|=bitmask;
else
dat&=~bitmask;
lcdSetColumn(i);
EN=0;
RW=0;
RS=1;
LCD=dat;
EN=1;
EN=1;
EN=0;
EA=ea;
}
=======================================================
【54楼】heyunqingfeng 的回复,并没有错,我对他的回复没有任何讽刺意思,是称赞。原因是:我也觉得很繁琐,没有精简,就以void lcdPutPix(uchar x, uchar y,uchar flag) 这个函数来说,那些开中断,关中断等,其实可以去掉的,没有必要的。还有画边框函数void rectangle(void) 其实我有简洁的方法(Bresenham算法),但是没有用,原因是我觉得我那样画边框速度慢一些。 mark下 很好很强大 MARK. 强势留名 mark 回复【楼主位】lzf713

谢谢 学习。。 等有时间了也要实现自己的这个愿望,弄个玩玩. 还是很强大啊!好好研究 mark 下来看看 电脑没电前……
mark…… 确实很强大啊,利用c语言编程控制,结合AT89X51单片机,很轻松的做出了一个小游戏,要好好学习! 好东西,MARK!!! 要了标记一下 mark===楼主很强大。。。 mark 漂亮 mark 能不能使用16*2lcd做啊 mark下先,不知到事物上会怎样 学习一下!!! 正想用12864玩显示
留下,学习 不错!!!转啦!!! mark 强大! 那个 图形是怎么弄得? 就是掉下来的黑色方块 强人,努力看齐!!! 搞12864不玩这个,不玩贪吃蛇,不玩播动画,不玩推箱子,遗憾~ 真是人才啊! 留下日后以定看 楼主确实很有实力 牛! 好贴,顶一下 真的不错,要学习下 强啊,就是没有注释。 厉害啊!! 学习··································{:smile:} 不错啊 {:lol:}{:lol:}{:lol:}mark,too. 很有趣的样子~~ 支持楼主,大爱楼主 学习一下谢谢分享 感谢分享,不错~! 很好,支持分享。
