win7 dos窗口模拟帧刷新
前几天是白色情人节，临时脑抽写了个表白神器 高端大气上档次，就是不知道该送给谁，经过两天的反射弧思考决定还是写给博客娘吧。- -~
这个程序就是打开后，在Dos窗口内模拟写出几行字母。其实主要就是模拟一下帧刷新。像游戏引擎那样每一帧都打印一个满屏，那么所有的动画也就出来了。想在里边写个小游戏也未尝不可。
但是理想丰满现实骨感，Dos窗口不断帧刷新效果很一般，是不是会出现跳动的情况，很蛋疼。
win7 dos窗口的默认宽度是80个字符，高度是25个字符。经过简单的处理，通过调用Sleep函数来控制间隔时间来无限打印80x25的字符串集合，就能模拟帧刷新了，非常的简单。
c/c++版本代码
#include <stdio.h> #include <iostream> #include <string.h> #include <stdlib.h> #include <windows.h> #include <vector> using namespace std; //全局变量 标记是否处于update状态 bool update_flag = false;
//全局数组，每一帧打印的所有字符 char* screen[25];
//全局变量,打印刷新计数器 int pro_count = 0; //结构体 代表80x25中的一个点 struct _pos { int _x; int _y; _pos(int x, int y) : _x(x), _y(y){} };
//刷新函数的函数指针 typedef void(*_update)(vector<_pos>&); _pos makepos(int x, int y) { _pos ret(x, y); return ret; } //初始化要打印的点阵 虽然屏幕是80个字符的宽度，但是字符要多一个，原因是\0的字符串结尾标识符占一个
//最后一行做特殊处理 没有\n换行符，以免每一帧的时候窗口被向下延伸一行 void init_screen() { for (int i = 0; i < 25; i++) { screen[i] = (char*)malloc(sizeof(char)* 81); memset(screen[i], ‘ ‘, sizeof(char)* 81); //if (i == 0) screen[i][0] = ‘x‘; screen[i][79] = ‘\n‘; screen[i][80] = ‘\0‘; if (i == 24) { screen[i][79] = ‘\0‘; screen[i][80] = ‘\0‘; } } }
//打印一帧的屏幕 上边缺失的换行符在这里补充 void display_screen() { printf("\n"); for (int i = 0; i < 25; i++) { printf(screen[i]); } }
//更改某一点的显示字符 void set_char(int x, int y, char target) { if (x >= 0 && x < 25 && y >= 0 && y < 81) { char* index = (screen[x] + y); *index = target; } }
//开始update函数 void start_update(_update update_function, int daley, vector<_pos>& _vec) { update_flag = true; while (update_flag) { Sleep(daley); update_function(_vec); } }
//停止update void stop_update() { update_flag = false; }
//每一帧执行的函数 void processing(vector<_pos>& _vec) { if (pro_count < _vec.size()) set_char(_vec[pro_count]._x, _vec[pro_count]._y, ‘o‘); display_screen(); pro_count++; }
//制作一个序列，这个序列用来保存需要 更改的点 void init_vec(vector<_pos>& vec) { vec.push_back(makepos(10, 5)); vec.push_back(makepos(11, 5)); vec.push_back(makepos(12, 5)); vec.push_back(makepos(13, 5)); vec.push_back(makepos(14, 5)); vec.push_back(makepos(10, 9)); vec.push_back(makepos(11, 9)); vec.push_back(makepos(12, 9)); vec.push_back(makepos(13, 9)); vec.push_back(makepos(14, 9)); vec.push_back(makepos(14, 10)); vec.push_back(makepos(14, 11)); vec.push_back(makepos(14, 12)); vec.push_back(makepos(14, 13)); vec.push_back(makepos(10, 18)); vec.push_back(makepos(11, 17)); vec.push_back(makepos(12, 16)); vec.push_back(makepos(13, 17)); vec.push_back(makepos(14, 18)); vec.push_back(makepos(14, 19)); vec.push_back(makepos(14, 20)); vec.push_back(makepos(14, 21)); vec.push_back(makepos(13, 22)); vec.push_back(makepos(12, 23)); vec.push_back(makepos(11, 22)); vec.push_back(makepos(10, 21)); vec.push_back(makepos(10, 20)); vec.push_back(makepos(10, 19)); vec.push_back(makepos(10, 25)); vec.push_back(makepos(11, 26)); vec.push_back(makepos(12, 27)); vec.push_back(makepos(13, 28)); vec.push_back(makepos(14, 29)); vec.push_back(makepos(13, 30)); vec.push_back(makepos(12, 31)); vec.push_back(makepos(11, 32)); vec.push_back(makepos(10, 33)); vec.push_back(makepos(10, 37)); vec.push_back(makepos(10, 38)); vec.push_back(makepos(10, 39)); vec.push_back(makepos(10, 40)); vec.push_back(makepos(10, 41)); vec.push_back(makepos(10, 42)); vec.push_back(makepos(11, 37)); vec.push_back(makepos(12, 37)); vec.push_back(makepos(12, 38)); vec.push_back(makepos(12, 39)); vec.push_back(makepos(12, 40)); vec.push_back(makepos(12, 41)); vec.push_back(makepos(12, 42)); vec.push_back(makepos(13, 37)); vec.push_back(makepos(14, 37)); vec.push_back(makepos(14, 38)); vec.push_back(makepos(14, 39)); vec.push_back(makepos(14, 40)); vec.push_back(makepos(14, 41)); vec.push_back(makepos(14, 42)); vec.push_back(makepos(10, 49)); vec.push_back(makepos(11, 50)); vec.push_back(makepos(12, 51)); vec.push_back(makepos(10, 53)); vec.push_back(makepos(11, 52)); vec.push_back(makepos(12, 51)); vec.push_back(makepos(13, 51)); vec.push_back(makepos(14, 51)); vec.push_back(makepos(10, 59)); vec.push_back(makepos(11, 58)); vec.push_back(makepos(12, 57)); vec.push_back(makepos(13, 58)); vec.push_back(makepos(14, 59)); vec.push_back(makepos(14, 60)); vec.push_back(makepos(14, 61)); vec.push_back(makepos(14, 62)); vec.push_back(makepos(13, 63)); vec.push_back(makepos(12, 64)); vec.push_back(makepos(11, 63)); vec.push_back(makepos(10, 62)); vec.push_back(makepos(10, 61)); vec.push_back(makepos(10, 60)); vec.push_back(makepos(10, 67)); vec.push_back(makepos(11, 67)); vec.push_back(makepos(12, 67)); vec.push_back(makepos(13, 67)); vec.push_back(makepos(14, 68)); vec.push_back(makepos(14, 69)); vec.push_back(makepos(14, 70)); vec.push_back(makepos(14, 71)); vec.push_back(makepos(13, 72)); vec.push_back(makepos(12, 72)); vec.push_back(makepos(11, 72)); vec.push_back(makepos(10, 72)); } int main(int argc, char* argv[]) { vector<_pos> poses; init_vec(poses); init_screen(); _update _s_fun = processing; start_update(_s_fun, 100, poses); system("pause"); }
