用VB编写贪吃蛇时可能遇到的难点和重点问题有什么？

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).

VB 做一个非常简单的贪吃蛇程序

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）

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：
