如何用慧編程做貪吃蛇代碼
用慧編程做貪吃蛇代碼過(guò)程如下：
1、我們需要建立四個(gè)頭文件，然后分別設(shè)置蛇的狀態(tài)，上下左右，這是蛇能夠有方向可走的前提，然后我們?cè)僭O(shè)置蛇身的節(jié)點(diǎn)，定義一個(gè)簡(jiǎn)單的函數(shù)，這樣蛇的全身以及他的行走方向就弄完了。
2、貪吃蛇不能穿墻代碼。
3、第二步，一個(gè)函數(shù)這個(gè)函數(shù)的目的是貪吃蛇不能穿墻，很簡(jiǎn)單的代碼分別設(shè)置長(zhǎng)寬的最大位移，在內(nèi)部范圍內(nèi)設(shè)置為一即可通過(guò)，否則不能穿墻。貪吃蛇隨機(jī)生成一個(gè)食物。
4、設(shè)置一個(gè)隨機(jī)函數(shù)。這樣貪吃蛇代碼就做好了。
慧編程是一款面向STEAM教育領(lǐng)域的積木式和代碼編程軟件，基于圖形化編程開(kāi)發(fā)。
