RenPy Cannot find Python Package Panda3d (for Ursina) and Pywin32 (for win32gui)
Posted: Tue Mar 28, 2023 3:12 am
Hello, I'm trying to put the output of ursina engine into RenPy's display. I've managed to do the same in pygame so I'm assuming that if it is possible in pygame, it would also be possible in RenPy. The following is my code with pygame:
This is the code in script.rpy:
When I launch the project I get this traceback:
I've installed panda3d, ursina, pywin32 and some other packages using the following command:
I also made sure I ran this command in the 'game' directory of my RenPy project.
The version packages pip installed were for python 3.10, but RenPy uses 3.9. How can I fix this?
