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

在这里插入图片描述

数字1表示红色区域内有1课雷,2表示有两颗

在这里插入图片描述

如何显示数字

在这里插入图片描述
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

在这里插入图片描述

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;

在这里插入图片描述

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

#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>
#include <time.h>using namespace sf;#define SIZE 10      //地图宽度enum {NONE_MINE = 0,MINE = 9, //地雷GROUND,  //地面FLAG     //旗帜
};enum {SUCCESS,FAILURE,GOING
};int unitSize = 64;
int mineData[SIZE + 2][SIZE + 2];  // 0:没有雷 9:有雷（以避免和雷的数字提示混淆）
int showData[SIZE + 2][SIZE + 2];
int mineCount = 0;bool success_flag = false;
bool failure_flag = false;void initMine() {//布雷for (int i = 1; i <= SIZE; i++) {for (int j = 1; j <= SIZE; j++) {showData[i][j] = GROUND; // 设置为未点击状态（“地面”）//布雷if (rand() % 5 == 0) {mineData[i][j] = MINE;mineCount++;}else {mineData[i][j] = NONE_MINE;}}}// 计算雷周围位置的数字显示for (int i = 1; i <= SIZE; i++)for (int j = 1; j <= SIZE; j++){int n = 0;if (mineData[i][j] == MINE) continue;if (mineData[i + 1][j] == MINE) n++;if (mineData[i][j + 1] == MINE) n++;if (mineData[i - 1][j] == MINE) n++;if (mineData[i][j - 1] == MINE) n++;if (mineData[i + 1][j + 1] == MINE) n++;if (mineData[i - 1][j - 1] == MINE) n++;if (mineData[i - 1][j + 1] == MINE) n++;if (mineData[i + 1][j - 1] == MINE) n++;mineData[i][j] = n;}
}int check(RenderWindow* window) {int count = 0;for (int i = 1; i <= SIZE; i++) {for (int j = 1; j <= SIZE; j++) {if (mineData[i][j] == MINE && showData[i][j] == FLAG) {count++;continue;}else if (mineData[i][j] == MINE && showData[i][j] == MINE) {failure_flag = true;return FAILURE;}}}if (count == mineCount) {success_flag = true;return SUCCESS;}return GOING;
}int main()
