又一个多月没动静了，也没干啥有意思的。
我们国庆放九天，还是挺爽的，虽然哪也没去，哈哈哈。
最近一直在练LOL，打派克，这英雄R起来着的爽，有位移有控制有伪装还有斩杀，感觉挺全面的。
还在玩MC，一直在肝单人1.17的存档。
前两天无聊，发现个软件，可以实现手机有线/无线投屏到电脑，延迟挺低的，
可以用电脑操控手机，试了试吃鸡，跟模拟器比还是一点点差距，毕竟只是个投屏。
QtScrcpy，Github地址：https://github.com/barry-ran/QtScrcpy
国庆假期就国庆当天阳光明媚，后面几天全是阴天，哈哈哈。
还远程玩了玩高中同学的电脑。
好像就没啥别的事了。明天又该回去了，呜呜呜。
在自己瞎搞地图画生成器之后去下载别人的生成器看了看，能输出地图文件、投影（一个Mod，但我没用过，只知道大体功能）文件，反正感觉没法直接搞到服务器里面去。于是想了点别的路子。
开始只是想编个脚本就解决的，结果发现很难搞。那个会单开一个文说说。最终我准备编一个Mod来实现，关于Mod开发我也会单开一个文（虽然我也是刚刚接触）。
首先是得搞一个平台，当作背景。随便一个地方，新生成一个地图，确定好边界，搞一个128*128方块的平台即可。
这个不太难实现，先确定一个地图的顶点，再向X轴、Z轴延伸。
这里有两个点得说一下：一个是我现在知道的Mod里放置方块的方法（useItemOn）不能在玩家一定格数之外放置方块（就和手动放置一样），所以得让玩家跟着动起来。另一个是，在服务器里moveTo方法不能在1Tick里移动超过一定格数，所以没法光两个for循环直接套。需要加点东西，让玩家蛇形走位。
大体思路就是这样：确定基点>>{放置方块>>蛇形走位>>}*n（下面的SetAndRun()方法）
再加上暂停、自动切换物品栏等功能，就比较完善了。虽然老是莫名崩溃😅
平台搭完，就该“作画”了，想不出什么太好的方法，就是通过Mod外面的（下面会有）程序，把图片（128*128像素）转换成0~9，储存到文档里。
Mod到时直接读取文档，文档内的0~8对应着游戏内1~9的物品栏，9对应空气（啥都不放），Mod会自动跳过去。
大体的思路：建立两个数组，一个储存第几个格子选择哪个物品栏（放什么方块）。另一个储存所有要放置方块的格子的格子数（第几个格子）。
第一个数组是给切换物品栏使用的，让Mod一次可以搭好几种方块，对应着下面的ChooseAndSet()方法。
第二个数组是给玩家移动用的，让玩家只走到要搭方块的地方，而不是128*128全逛一遍，节约时间，对应的是下面的WantGo()方法。
下面就是代码了，前面是生成地图文档的java程序，后面是Mod的程序。
这会试了试，现在的代码在这里就能读了，不用再复制到IDE里了😉

}不是能直接导入的那种，只是颜色的替换。。。
因为太懒（技术也不够😅），所以只考虑平面地图画，平面的材料也只有各种地毯。效果肯定没那些大佬们的好，只是瞎编着玩的东东，实际作用有限。
我是把RGB转换为Hsl，并通过寻找相近的H（色相）来替代颜色。s（饱和度）过低与l（亮度）过高或过低时直接走黑白模式通过亮度确定颜色，不通过色相判断。
下面的文档里整理了一下羊毛毯在地图上的颜色的RGB值及其H值。
>>>羊毛毯地图画.docx<<<
再下面是具体的程序，水平有限，肯定会有一些瑕疵啦。
这里没缩进，想看的复制去IDE里看吧😉
