I have a #CreativeCoding course at Domestika, teaching the first steps of #Python and #py5. The feedback from students always makes me happy!

What is a #GameEngine for you? Is there a gray area between game engines and graphics frameworks? You can make games with SDL, RayLib, Processing (and py5…), p5js, d3js, but would you consider them game engines?
Maybe I should ask my students to make a game engine purist-neutral-radical alignment chart ? 🤡
Updating my #Processing + #Python tools table:
After some years, things changed and my opinions changed a bit too:
#py5 is going supper strong and the “new snake_case names” are not an issue for me anymore. I used to worry a lot about all the Processing Python mode examples and teaching materials out there, and some of my own, with “CamelCase Processing names” I’m not worried at all about it anymore!
For the record, Processing Python mode is just a legacy thing, no one should start anything with it.
The great pure Python Processing implementation project #p5py seems stalled, latest release in Dec. 2023 :((( Advancing it was always going to be an uphill battle…
The unrelated Brython based site
p5py.comseems to be gone, so I removed it from the table.I added a link to my own #pyp5js hack py5pjs/py5mode because this is what I’m using most nowadays.

So I went to see the documentation:

And came out empty handed, that is, couldn’t understand what to do instead :(
And the plot thickens:

(@py5coding I guess you’ll want to check this out at some point. py5_tools.animated_gif uses this)

#GitHub #GitHubPages #fail This is driving me mad…
Images randomly deciding not to load on all my pages.
Is it just me? Is it my browser’s fault? Is it just in Brazil?
I was working on this #shapely + #trimesh page… and I can only see the last image (the animated gif)!

Update: On this exact page I have bungled the image URLs (I blame Marktext for being stupid and not using a relative reference). But I swear loading problems have been going on other well formed pages.
This is your friendly reminder that you could be making #PaperObjects with #Python and #py5, you know?
