system指令

一、光标

1、隐藏光标

    void HideCursor()
    {
    	CONSOLE_CURSOR_INFO cursor_info = {1, 0};
    	SetConsoleCursorInfo(GetStdHandle(STD_OUTPUT_HANDLE), &cursor_info);
    }//隐藏光标

2、获取光标位置

作者觉得这个指令不是很常用，备用吧。

    函数返回 COORD 类型的指针位置，用 .x .y 获取 x y 坐标

    COORD GetCursorPos()
    {
    	HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);
    	CONSOLE_SCREEN_BUFFER_INFO bInfo;
    	GetConsoleScreenBufferInfo(hOut, &bInfo);
    	return bInfo.dwCursorPosition;
    }//获取光标位置

3、移动光标

参数分别是目标位置的 x y 坐标

    void gotoxy(int x, int y)
    {
    	HANDLE hout;
    	COORD pos;
    	pos.X = x;
    	pos.Y = y;
    	hout = GetStdHandle(STD_OUTPUT_HANDLE);
    	SetConsoleCursorPosition(hout, pos);
    } //移动光标

二、窗口大小

1、调整大小

作为一个像样的游戏窗口总有一个合适的大小，不可能用控制台默认的奇怪的大小。

参数分别为窗口行列的数量

    void setsize(int col, int row)
    {
    	char cmd[64];
    	sprintf(cmd, "mode con cols=%d lines=%d", col, row);
    	system(cmd);
    }//调整窗口大小

2、固定大小

调完大小，会发现一个问题：有些不听话的玩家会自行调整窗口大小，于是我们就要固定窗口大小，禁止玩家调整。

SetWindowLongPtrA(GetConsoleWindow(), GWL_STYLE, GetWindowLongPtrA(GetConsoleWindow(),GWL_STYLE)& ~WS_SIZEBOX & ~WS_MAXIMIZEBOX & ~WS_MINIMIZEBOX);//固定窗口大小
