Python dependencies

First, make sure you have CPython 3.13 installed on your computer. You cannot use other version of python, only 3.13 is supported for now. Make sure too that you use python 3.13 while building, and not any other installed version. To be sure which version you use, use python3.13 and not python3 in the commands.

Protobuf installation

Then, install protobuf. I don't remember why we need version 3.20.0, but as I remember, that's the latest supported version. To install protobuf, use this command:

python3.13 -m pip install protobuf===3.20.0

Panda3D installation

To build Ursina For Mobile binaries, you need to build Panda3D on Android. WARNING: TO BUILD PANDA3D FOR ANDROID, YOU CANNOT, ON YOUR PC, USE A STABLE WHEEL OF PANDA3D. So, it's required to use a beta wheel.

There are multiple wheel for multiple os, here are some:

  • Windows (64 bit): 
    python3.13 -m pip install https://buildbot.panda3d.org/downloads/b32d5c672441c280f7e799483d223e252cf9f797/panda3d-1.11.0.dev3788-cp313-cp313-win_amd64.whl
  • Linux (64 bit): 
    python3.13 -m pip install https://buildbot.panda3d.org/downloads/b32d5c672441c280f7e799483d223e252cf9f797/panda3d-1.11.0.dev3788-cp313-cp313-manylinux2014_x86_64.whl
  • MacOS (Universal (Intel and Apple Silicon)(Not recommended)): 
    python3.13 -m pip install https://buildbot.panda3d.org/downloads/b32d5c672441c280f7e799483d223e252cf9f797/panda3d-1.11.0.dev3788-cp313-cp313-macosx_11_0_universal2.whl
  • MacOS (Intel - 64 bit): 
    python3.13 -m pip install https://buildbot.panda3d.org/downloads/b32d5c672441c280f7e799483d223e252cf9f797/panda3d-1.11.0.dev3788-cp313-cp313-macosx_10_13_x86_64.whl

You can grab other wheel from the buildbot. Make sure you use wheels that have:

  • panda3d-1.11.0.devXXXX version in the wheel
  • cp313 python version of the wheel
