游戲設計

• 首先我們需要使用第三方框架,這里我使用的是sfml,不會使用sfml在我的上幾篇文章當中-掃雷(上)有詳細的開發環境搭建介紹

• 首先準備圖片資源

• 一張背景圖片,一張寶石圖片

• 窗口初始化加載圖片

• Texture t1;
  t1.loadFromFile(“images/bg2.png”);
  

• 當鼠標第一次單擊時,記錄下位置,第二次單擊又記錄一下位置,如果兩個小方塊相鄰就交換位置,如果不相鄰如圖c的位置則,不發生變化
  

• 判斷行或列如果三張一樣的圖片相鄰,清除一下圖片,進行刷新

實列

• 由于上一篇掃雷和消消樂中有過多的相似之處所以這里就詳細一 一介紹了,具體詳細過程在我的主頁參考掃雷(下)
