1、向上前進的時候，對代碼進行一個詳解。
2、向上前進時，x坐標不動，y坐標-1，如果下一個有食物 下一個位置的坐標和食物的坐標相同。把食物轉(zhuǎn)化成蛇的身體。
3、如果蛇吃到了食物，就開始加速，并且食物的得分+2。
4、如果沒有吃到食物，蛇可以正常往前走，恢復原來的方塊。
5、向下前進時，x坐標不動，y坐標+1。
6、如果有食物就把食物轉(zhuǎn)化為身體。
7、如果沒有吃到食物，蛇可以正常往前走，恢復原來的方塊。
朋友給段代碼給你，這個代碼不要任何控件，你只需要把以下代碼復制到你的窗體代碼中就行了,代碼很簡單，相信你能看懂！僅僅用了一個結(jié)構(gòu)（ShenTi）一個數(shù)組（ZhuangTai(23, 23) As Long） 一個變量（GFangXiang）
代碼中自動生成了Timer1，Label1控件。以及幾個函數(shù)（Randomize，Circle，Line，Erase...） 相信這些對于你來說很簡單，只是沒想到用這些方法來實現(xiàn)而已，現(xiàn)在你開始看看效果吧！

如果只是簡單的貪吃蛇的話,把蛇的基本圖形設(shè)置成圓(或正方形),蛇身由一串基本圖形構(gòu)成,每過一秒,檢測前面是什么,如果是空的,那么把頭畫成普通身體的樣子,再在前方(或側(cè)面,如果轉(zhuǎn)彎的話)再畫一個頭,并將其坐標記入數(shù)組,數(shù)組要足夠大,再把尾巴畫成背景色;如果前面是食物,尾巴就不刪除.這里的難點是數(shù)組里的操作和坐標的表示:把頭添在最后一個元素,把第一個元素提取(也就是尾巴).
