This is the second tutorial with ursina, because now I use Python version 3.12.1 and Ursina comes with version 7.0.0 .
The install is easy with the pip tool.
pip install ursina

- Mac (not officially supported, but will most likely work)
I tested with samples from the GitHub project and works well.
