23<p>The setup for this post is that in a vanilla Minecraft server there
24isn't a way to set the protection size to <code>0</code> (yes, I know bukkit can do
25this but, meh). This makes having the spawn in the middle of a nice
26area with shared chests, smelting, etc. a pain. So I wanted to move the
27spawn but I didn’t want to have to download the whole world, open it
28with a map editor, and then re-upload the whole thing again. Especially
29since I know the values are just stored inside the level.dat. So, below
30is how I used twoolie’s python NBT interface to move the spawn on our
31server.</p>
32
33<p>To install NBT, grab it from either <a
34href='https://github.com/twoolie/NBT'>github</a> or <a
35href='http://pypi.python.org/pypi/NBT'>pypi</a></p>
36
37<p><code>python spawn-move.py
38from nbt import *
39level = nbt.NBTFile('/<insert.path.here>/world/level.dat','rb')
40level["Data"]["SpawnX"].value = newx
41level["Data"]["SpawnY"].value = newy
42level["Data"]["SpawnZ"].value = newz
43print(level.pretty_tree()) # show changes
44level.write_file('/<insert.path.here>/world/level.dat')
45exit()
46</code></p>
