百行代码手撸扫雷(下)c/c++

• 在上一篇文章中已经带大家如何搭建开发环境了

需求分析

• 这里是一个8*8的地图
  

地雷随机分布数字表示周围一共有多少颗雷

数字1表示红色区域内有1课雷,2表示有两颗

如何显示数字

右上角没有如何判断呢?行加1或列加一不就越界了吗,所以为了帮面条件判断我们把8行8列改成10行10列

游戏实现

• 先包含头文件

• #include <SFML/Graphics.hpp>

• #include <SFML/Audio.hpp>

• 初始化窗口大小,就类似于我们要搭台唱戏一样,需要一个舞台这个舞台大小需要多大,我们需要指定一下舞台大小,不指定怎么知道需要多大的舞台呢?这就是初始化

• 初始化窗口: RenderWindow window(VideoMode(800, 800), “Canxin-MINE”);

• RenderWindow window(VideoMode(窗口宽度,窗口高度),“窗口右上角的描述信息”);
  宽为x坐标,高为y坐标;

• 获取当前鼠标点击的x坐标和y坐标

• Vector2i pos = Mouse::getPosition(window);

• 我们要把鼠标的x坐标和y坐标转化成行和列,就需要鼠标的x坐标除以方块的像素宽度,y坐标也是一样
