前言:
烟花的实现是我自己独立实现的第一个项目。那时离除夕只剩几天,我刚学完贪吃蛇。其实个人也很喜欢烟花。所以想送给朋友一份礼物。于是觉得可以一试。构思了一会后,就直接进行了。
成品:
思路:
1.vs2022很多特殊字符都打印不了。我首先把c语言本地化,然后复制了许多特殊字符,尝试它们在控制台能打印出来的结果,把能够打印出来的筛选字符都列出来。这样在烟花制作的过程中也许会用上。
2.烟花的画面是这样的。
下面是花筒,上面是烟花在上升时的花束和升到制高点时绽放的花体。
3.烟花如何实现
花筒直接用宽字符打印出来就可以,烟花的花束需要设置一个结构体,和贪吃蛇的蛇身一样(贪吃蛇的实现见上篇文章),只不过是单向向上移动,而且移动的速度要快许多。(睡眠的时间少很多)
烟花的花体也是一个结构体。这个结构体的构成也是一个个结点。你构建的结点个数,取决于一次绽放闪烁的火花有多少个。我尝试了一下,在9-15是最合适的,选择了12个结点。这些结点的坐标都用随机数设置。限制在上图的方体区域中。绽放一次睡眠一次。一个花筒得闪个四五次吧,在外面套上一层循环就可以了。
但是闪烁之后要消失,这个怎么处理?
借助贪吃蛇的删尾的思路,在原坐标处打印两个空格字符就可以覆盖掉。所以花体绽放之后还要写个循环来清理这些花体。
再来说花束的移动,花束升到至高点(指定坐标)后,再清理掉花束。
以上就可以完成简单的烟花播放了。(虽然是长方形的烟花)
如果要循环播放,就要在外面套个循环体。把烟花的初始化放在循环体外面。
