C#打字遊戲案例（純代碼實現）

一、需求分析

1、界面設計 佈局

• 需要哪些內容控件
• 容器的概念
• 集合的概念

2、開始遊戲

• 字母的生成 26個字母 ASCII碼值
• 字母的載體 控件
• 字母、位置、大小、顏色
• 要求隨機的
• 計時器

3、字母從上往下運動

• TOP變化
• 注意：垃圾回收問題，未消除的字母進行銷燬，釋放資源
• 計時器

4、需要產生對應的從下往上生成字母子彈，打掉字母

• 處理與鍵盤之間的交互，鍵盤相關事件
• 字母需要轉換，ASCII碼值
• 知識點：事件參數：EventArgs e
• 子彈從下往上運動
• 子彈與字母相遇，兩者消失

5、添加動畫效果、音效等
