Steve Martin 和 Andrew Oakley 的教程
公有领域 2018 年 5 月 17 日 www.cotswoldjam.org
要启动 Minecraft，请点击 Pi 菜单 - 游戏 - Minecraft Pi
点击开始游戏，然后点击现有游戏或点击创建新游戏
Tab ↹ 键在 Minecraft 世界和桌面上的正常鼠标之间切换。 Tab ↹ 键位于字母 Q 的左侧。
Esc 用于游戏菜单。
| 控制 | |
|---|---|
| 鼠标看 | 0 选择剑 |
| WSAD 移动 | E 重新分配块 0-9 |
| Space 跳跃 | Space 两次飞行 |
| 左键点击破坏块 | Space 再次两次停止飞行 |
| 右键点击创建块 | Space 飞行时一次向上 |
| 1–9 选择块类型 | ⇧ Shift 飞行时向下 |
要使用 Minecraft 编程，请保持 Minecraft 运行。按下 Tab ↹ 键从游戏中释放鼠标，以便您可以使用桌面上的鼠标。
点击 Pi 菜单 - 编程 - Python3 (IDLE) 文件菜单 - 打开 - python/minecraft-dungeon/myDungeon.py
from Dungeon import Dungeon
dungeon = Dungeon()
entrance = dungeon.create()
room1 = dungeon.newRoom(entrance, "N")
使用运行菜单 - 运行模块运行程序。您应该看到一个通往房间的楼梯。
在程序中添加更多房间，例如
room1 = dungeon.newRoom(entrance, "N")
hallway = dungeon.newRoom(room1, "N")
bedroom = dungeon.newRoom(hallway, "W")
lounge = dungeon.newRoom(hallway, "E")
做一个迷宫！
