【问题描述】:
我目前正在为一款游戏开发一个已发布的机器人,希望能更多地了解编程。不幸的是,当我进入二进制数组的主题时,我添加的一个起初看起来很简单的新命令变得非常困难。基本上,我采用了一个已经制定的命令,在该命令中,您将一个项目放置在两个地方,以定义您将要恢复的区域。我对该命令的编辑是,它将允许完全恢复整个地图,而无需放置任何项目来定义地图。
在执行还原命令之前,会执行备份命令,其中二进制数组由整个映射组成,然后存储在文件中。为了恢复整个地图,新的命令还是要处理两个点的坐标。一个位于地图的底角 (0,0,0),然后另一个位于地图顶部对面的拐角处,这将始终根据您想要的服务器而有所不同。我解决这个问题的理由是简单地检索每个坐标的二进制数组的长度。不幸的是,我一直不走运,我真的不知道如何找到二进制数组的维度。显示了数组的打包和解包以及我无法解决的部分代码。
一个奇怪的事情是,如果我像 if 语句那样手动输入数字,使用那个服务器 IP 地址,机器人就可以完美运行。只是任何努力编写适用于任何地图的代码而不仅仅是一张地图都没有结果。

【问题讨论】:
-
x2,y2,z2不应该和header_x,header_y,header_z一样吗?
-
其实答案可能是 header_x,y,z 的 len
