• c++游戏入门基础


    1、windows.h

     1.1、SetConsoleTextAttribute//设置控制台文本颜色

    1 void color(int a)//颜色函数
    2 {
    3 SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),a); //设置控制台颜色
    4 }

    附上各种颜色代码对应的数字:

     1 #include<iostream>
     2 #include<windows.h>
     3 
     4 using namespace std;
     5 void color(int a)
     6 {
     7     SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),a);
     8 }
     9 
    10 int main()
    11 {
    12     for(int i=0;i<=16;i++)
    13     {
    14     cout<<"数字 :"<<i<<" 的颜色是"<<std::endl;
    15     color(i);
    16     //cout<<"颜色"<<std::endl;
    17     }
    18     system("pause");
    19 }

    运行截图:

    1.2、SetConsoleCursorPosition //设置光标位置

    1 void Pos(int x,int y)//位置函数
    2 {
    3 COORD pos;
    4 pos.X=2*x;
    5 pos.Y=y;
    6 SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),pos); //设置光标位置
    7 }
