A simple Python script to generate a sequence of /tp commands intended to pre-generate a Minecraft world.
This was inspired by Xisumavoid's video on pre-generating the Hermitcraft season 7 world.
In Minecraft, worlds are randomly generated. This means when a player is exploring new parts of their world, Minecraft first has to generate the area before it can load it, which can produce high amounts of lag if there are multiple players all exploring new areas.
The aim of this script is to teleport the player around a certain area so as to generate the terrain and save it in the world. That way, when this world is imported into a server with multiple people playing, the server only needs to load the area (assuming players stay within the pre-generated regions) which alleviates strain from the server, resulting in better performance for the players.
The script uses the keyboard Python module
to generate and type out /tp commands, which teleport the player in a grid
pattern spaced 240 blocks apart. For each location teleported to, the player
is rotated in all four compass directions (North, East, South, then West) and
waits a given amount of time between teleports, to give Minecraft the best
opportunity to generate chunks around the player's location.
To run this program for yourself, make sure you have Python 3 installed. You
will also need the keyboard module, which you can get using pip. Note it
is recommended to create a virtual environment first.
pip3 install keyboard
Now you can run the module with Python.
python3 -m minecraft_pregenerator
This will take you through a command line interface where you can enter your desired values for the different parameters.
By default, the script is set to teleport the player over an area of 5760x5760
centred on the origin. Teleports are spaced 240 blocks apart, and it waits for
2 seconds between teleports. If you just want to run the script with these
default settings, then you only need to download script.py and run it:
python3 script.py
Once you answer y in the script, you will have 10 seconds to make Minecraft
the active window before the script starts typing the commands!
