使用Python在Minecraft中建造城堡

一旦我尝试了Minecraft-Python API，我就想要一个小项目来尝试一下。因此，我决定创建一个脚本，该脚本将自动创建一个带有护城河和几个外围墙的城堡。

This seemed like a good choice as the walls and the keep are really the same construct just a different width and height. 的keep would just need a bit of extra work to add floors, windows and a door.

这是完成的城堡。

设定

要使用以下脚本，您需要安装Minecraft和Python API。在最新的Raspbian图像中，Minecraft和API已经设置好，因此您可以直接进入有趣的地方。

Download 的Castle Builder Script

这是我的脚本：

#!/usr/bin/python
#--------------------------------------
#
#     我的世界 蟒蛇 API
#        Castle Builder
#
# This script creates a castle complete
# with moat and perimeter walls.

需要注意的几点

的“CreateLandscape”函数清除了整个Minecraft世界（256x256x256立方体）。它将上半部分设置为“air”而下半部分“dirt”. It adds a top layer of grass to the 污垢. You may wish to save your world if you have been working 上 something else as running this script will replace it.

的castle will be placed directly in the centre of the world.

运行脚本来建造城堡

在Minecraft运行时，您可以使用以下命令在终端窗口中执行Python脚本：

蟒蛇 castle.py

根据您使用的体育彩票31选7型号，最多可能需要20秒才能完成。

的script consists of some function definitions with the main script at the end just calling these functions. This makes it easier to tweak a function 上ce and it then be used multiple times.

的perimeter walls are created using the 蟒蛇 function “CreateWalls”具有不同的宽度和高度。它们的内边缘和城垛都有木制人行道。

的Keep is created using “CreateKeep”依次调用“CreateWalls”. 的Keep is just a set of walls that are taller than the others. It has battlements and a wooden walkway.

的inside of the keep has floors splitting it up into a number of levels. You can make the Keep taller by telling “CreateKeep” to use more levels.

的“CreateKeep”功能还可以在地面墙壁上打一个孔以形成门口。

的function “CreateWindows”将窗口添加到Keep的所有侧面。小心你别’t fall out!

In general the 蟒蛇 API is really easy to use. 的hard bit is working out the x,y,z co-ordinates so that blocks end up in the correct place.

未来升级

的obvious thing that is missing is a way of getting from 上e Keep floor level to another. This really needs a new function to create a hole in the floor with some steps which can be called for each level as it is created in the “CreateKeep” function.
