Minecraft API
This is a reference of Minecraft Python API Library, which is supported on Minecraft: Pi edition and the PC version using the RaspberryJuice plugin.
If you want to know more about how to use the API, including tutorials, see my projects and download code, visit my minecraft page.
Structure
- minecraft.py
- block.py
- event.py
- vec3.py
- connection.py - internal module used by the api
- util.py - internal module used by the api
Compatability
Not all functions and block types are available on all version of the api, by each function you will see a logo which shows whether that function is available:
Available on Minecraft: Pi edition
