Suppose someone wanted to teach computer programming concepts using Julia through interactive graphical animations a-la scratch ? Are there any packages that let you open a window and draw objects/move them around/animate them? I’ve seen Luxor, but it seems like it’s designed around drawing static i…

[image] dlakelan: Suppose someone wanted to teach computer programming concepts using Julia through interactive graphical animations a-la scratch ? I would recommend that they just use Scratch directly. Julia is an extremely powerful language, but it contains a lot of ingredients that are no…

Yeah, the audience here has already learned some scratch, and wants to move up to something a little more useful to control stuff on an RPi but the motivating factor of watching graphics move around on the screen is still strong.

Personally I would go for https://racket-lang.org/ which has books on programming for children. A very nicely designed Lisp dialect. After which one can move to Julia, which is another very nicely designed Lisp dialect :wink:

Awesome I had never heard of Racket but will check that out quite thoroughly!

In particular, [image] Bootstrap Teaching Algebra through Computer Science seems very nicely designed.

The responses here give a lot of examples of alternative teaching languages to Scratch, but I’m still interested in the original question. Are there Julia packages for live sprite-like object animation and interaction (e.g. collision detection) in a window?

Yes. I’m still interested in that sort of thing as well. Right now I’m looking into doing a GtkReact based window for very simple Mandelbrot set drawing, zooming, interaction. I think you could probably do sprite based stuff this way too, but it’s all going to be fairly low level.

If you are looking for general interactivity with few constraints, Pluto.jl might be useful. It displays arbitrary graphics, and if those graphics depend on parameters defined in other cells, the graphics will get updated immediately when their params change. You can also do animations by having v…

Hey! I am very interested in this question! kolia mentioned my Pluto.jl project, which is primarily designed for the undergraduate level. It does make programming and interactivity easier, but it does not provide anything exciting (graphics, games) on its own. Pluto with Luxor might be nice for edu…
