你有没有想过用python制作一个Minecraft?在github上就有这样一个python程序（链接：https://github.com/zifan-wang/Minecraft.git）,玩起来还像模像样的：
一.游戏截图
二.代码分析
在游戏的文件夹中共有这些文件：
1.main.py
代码：（如有需要可复制，不需要可直接跳过）

一共800多行代码，是程序的主要文件
settings.py
在这个开源的程序中，有许多设置是我们可以自己更改的，在setting.py中就提供了许多选项：
import math
TICKS_PER_SEC = 120
SECTOR_SIZE = 16
GTIME = 0 # 当前世界时间
GDAY = 0.0005
GNIGHT = 0.0015
WALKING_SPEED = 5 # 走路速度
RUNNING_SPEED = 8 # 跑步速度
FLYING_SPEED = 15 # 飞行速度
SWIMMING_SPEED = 4
GRAVITY = 25.0 # 重力
MAX_JUMP_HEIGHT = 1.5 # 最大跳跃速度
JUMP_SPEED = math.sqrt(2 * GRAVITY * MAX_JUMP_HEIGHT)
TERMINAL_VELOCITY = 35 # 终端速度
PLAYER_HEIGHT = 2 # 玩家高度
WORLDLEN = 64 # 世界长度
BASELEN = 8
TEXTURE_PATH = 'texture.png' # 纹理文件
NRC = []
DNRC = []
def getlen(x, y):
return math.sqrt(x*x+y*y)
for x in range(-4,5):
for y in range(-4,5):
if getlen(x*BASELEN, y*BASELEN) <= 32:
NRC.append((x*BASELEN, y*BASELEN))
for x in range(-1,2):
for y in range(-1,2):
DNRC.append((x*64, y*64))
texture.png
这个图片文件是一个纹理文件，包含着游戏中用到的纹理
包含了天空、西瓜、钻石、铁、树叶、雪块、南瓜、TNT、草块、沙块、冰.......
三.需要用到的包
这个程序用到了numba和pyglet两个包
pip insatll numba
#numba包：提升运行速度
pip install pyglet
#pyglet包：3D构建四.游戏内容
1.地图种子
众所周知，MC中有地图种子这个东西，不同的种子对应不同的地图，但这个程序中都是一个种子，也就是说，无论你打开几个地图，地形都是一样的，并且遗憾的是，无法保存地图，所以只能用来娱乐一下。
2.游戏控制
W:向前
A：向左
S：向后
D：向右
space:跳跃
Tab:飞行
1-9:切换方块
左键：破坏方块
右键：放置方块
esc:暂时释放鼠标
