管道鸟cortex-M4（TM4C1294）

xiaoxiao2026-06-09 3

看到满屏的贪吃蛇，我也来开源一个Ti开发板（TM4C1294）的游戏将简化版的管道鸟，根据自己玩的经历，在cortexm4开发板上重新撸了一边，设计思路：设计思路：将小鸟固定在一条竖线上规定其只能上下移动并记录下其最高和最低的坐标，管道从屏幕右边开始出现依次移动到屏幕左边消失，用户通过按键控制小鸟上下移动，小鸟也有一个自然下降的速度,用户要控制小鸟在前进过程中不碰到管道的边和屏幕的边界。主要的方法是：画管道按横坐标宽60个像素将屏幕分成4等分，第一块产生随机高度的管道，第二，三，四块在管道运动到相应的块结束时接着上一块的结尾显示；画小鸟选取15x15像素的一块区域，以中心点计算出鸟上各个点的坐标，在画鸟时只需知道其中一个点就可以画出鸟。画的鸟如下图：移动鸟，先将前一步鸟所在的位置的图像消除，再根据中心点的位置变化计算出其他点的位置画出新的鸟位置。鸟中心坐标改变是靠按键中断来实现；重新开始是在屏幕上确定一块区域当触摸那块区域后从新开始。源代码
