C语言—推箱子

这个小游戏设计起来不难,之所以做他的目的是,一天老师给我了个他很早以前写的2D库,让我去使用这个库完成一个小游戏,这个过程的意义再去让我一个以前从未用过别人手写库的学生,了解到了库的设计结构,和如果好的使用别人的库去完成任务,虽然编程难度不大,但是意义深刻,至少知道了以后遇见别人的库是怎么使用,而不会手忙脚乱。

同时让我了解了游戏制作时的一些小方法如掩码的使用,和图像渲染的步骤,分层渲染的意义以及当有多函数具有同样功能和机构时,我们需要尽可能的去合并函数,这里指的就是上下左右的移动,因为观察到很多网上的博客里面都是四个方向每一个方向一个函数,所以我觉得我这里展示出来还有有一点意义的(一点点)。好了接下来就是代码显示了,请各位看官多多雅正

哦对了,在这我把我老师的2D库github放出来,有需要的话可以自取,我的老师也很欢迎大家共同学习,网站上有各个api的试例,很简单上手—》2D库链接

还有一件事就是,应为代码比较短,我懒得划分文件了,我写在了同一个文件中(这是不对的做法,切勿学习),但是虽然我在一个文件中写的,但是我写的方式还是按照划分模块的方式去完成,通过调用各个接口完成任务,没有直接放在全局变量里,还有一点就是有一些函数可能会毫无作用,甚至莫名其妙,这个当时是为了日后改进预留的接口,例如使用文件去存储每个关卡的地图信息等,但是因为有一些别的任务,所以一直耽搁了,在这我就先不完成了,麻烦原谅。所以目前是一个单关卡地图的推箱子

代码中需要注意的地方就是,比如图片和文字资源你需要自己上网下载,在这我就不一一上传了,谢谢。其中如地图的设计方法,就是我根据游戏画面的多层渲染的方式,结合自己的理解设计的,并没有直接放箱子和果实以及人的信息直接存放到map数组中,这只是我自己理解的一种设计方式,至于对不对就仁者见仁了。
