pyblocks

A block world you build with Python. To make something happen, you must program it yourself. If you need help with something feel free to ask. — Mr. Weimer

You can also download an untested multiplayer version. It only works on one machine or across one network. Eventually this will become the working version.

This version can host and join a game.

This version only allows joining a game.

Setting it up

• Download the zipped folder and unzip it anywhere you would like to keep it. It is a Windows program.
• Open the pyblocks folder and double-click pyblocks.exe. Nothing else needs installing as Python comes inside the folder.
• Save your programs somewhere outside the pyblocks folder, so a newer build does not take them with it when you replace the old one.
