前言

相信很多小伙伴還不知道貪吃蛇是怎么誕生的，貪吃蛇由來介紹：
1976年，Gremlin平臺推出了一款經典街機游戲Blockade。游戲中，兩名玩家分別控制一個角色在屏幕上移動，所經之處砌起圍欄。角色只能向左、右方向90度轉彎，游戲目標保證讓對方先撞上屏幕或圍欄。
Blockade 很受歡迎，類似的游戲先后出現在 Atari 2600、TRS-80、蘋果 2 等早期游戲機、計算機上。但真正讓這種游戲形式紅遍全球的還是21年后隨諾基亞手機走向世界的貪吃蛇游戲——Snake。

總結

和別的游戲不同，貪食蛇是一個悲劇性的游戲。許多電子游戲都是以操作者的勝利而告終，而貪食蛇的結局卻是死亡。不管玩得多么純熟，技術多么高超，你最終聽到的都是貪食蛇的一聲慘叫。當手機上的小蛇越長越長，積分越來越高的時候，死亡也就越來越近。那時候忙的不是為了吃豆子長身體，而是為了避免撞墻。你會發現你窮于應付，四處奔忙。貪食蛇最要命的就在一個“貪”字上。

在學習編程的過程中無疑實戰才是學習成果最好的驗證，所以要不斷的進行代碼練習以及項目實戰，本博客《項目實戰合集》專欄為各位提供了各類項目的實戰源碼，希望各位有所受益，喜歡的小伙伴記得點波關注和贊，謝謝！
