How do you use canvas with Brython?

Question

I tried to use canvas with Brython but it won't work. I did requestAnimationFrame but it throws an error, I do a while True but it just doesn't run at all.

Answer 1

There is no requestAnimationFrame global variable in Brython. An alternative function request_animation_frame from browser.timer is used.
I tried to fix your code with it, but it gives another error about object cloning; I cannot help you with it for now.
And I have found a short introduction to using Canvas2D with Brython, it may help you: https://agentultra.com/blog/JUMP_LINK__&&__python__&&__JUMP_LINK-and-canvas2d-with-brython/ .

Answer 2

get I got it to work. If you import "window" and use "window.requestAnimationFrame"it works

As for the link, unfortunately it gets blocked on Firefox for insecure connection :/
