朋友给段代码给你，这个代码不要任何控件，你只需要把以下代码复制到你的窗体代码中就行了,代码很简单，相信你能看懂！仅仅用了一个结构（ShenTi）一个数组（ZhuangTai(23, 23) As Long） 一个变量（GFangXiang）
成都创新互联成立以来不断整合自身及行业资源、不断突破观念以使企业策略得到完善和成熟，建立了一套“以技术为基点，以客户需求中心、市场为导向”的快速反应体系。对公司的主营项目，如中高端企业网站企划 / 设计、行业 / 企业门户设计推广、行业门户平台运营、APP应用开发、手机网站制作、微信网站制作、软件开发、联通服务器托管等实行标准化操作，让客户可以直观的预知到从成都创新互联可以获得的服务效果。
代码中自动生成了Timer1，Label1控件。以及几个函数（Randomize，Circle，Line，Erase...） 相信这些对于你来说很简单，只是没想到用这些方法来实现而已，现在你开始看看效果吧！
代码如下：

1、向上前进的时候，对代码进行一个详解。
2、向上前进时，x坐标不动，y坐标-1，如果下一个有食物 下一个位置的坐标和食物的坐标相同。把食物转化成蛇的身体。
3、如果蛇吃到了食物，就开始加速，并且食物的得分+2。
4、如果没有吃到食物，蛇可以正常往前走，恢复原来的方块。
5、向下前进时，x坐标不动，y坐标+1。
6、如果有食物就把食物转化为身体。
7、如果没有吃到食物，蛇可以正常往前走，恢复原来的方块。

如果只是简单的贪吃蛇的话,把蛇的基本图形设置成圆(或正方形),蛇身由一串基本图形构成,每过一秒,检测前面是什么,如果是空的,那么把头画成普通身体的样子,再在前方(或侧面,如果转弯的话)再画一个头,并将其坐标记入数组,数组要足够大,再把尾巴画成背景色;如果前面是食物,尾巴就不删除.这里的难点是数组里的操作和坐标的表示:把头添在最后一个元素,把第一个元素提取(也就是尾巴).
