Could you wait a bit?

had a nice discuss with @perborgen around this.

just to add to what i said above, moving from current paradigm where you "snapshot the DOM" over time to a paradigm where you would play the real code and replay all recorded events is tricky..

Not only you need to record all events, like click events.. but also you potentially need to override & sandbox the "timers" (setTimeout, etc..). that way, you might be able to replay something in a deterministic way? There are still hard things like image loading that you can't really control so I don't know if it's easily possible..

But still, even doing that, i'm not even sure how you would solve it if a user "jump" at a given position.. (replay from the start? nah :D)

At the end, there will be probably some tradeoff and the creators will need to be aware of these..

For my gl-react usecase, I was actually thinking a workaround could be that would capture my Canvas at 60fps and when it changes, it would inject a <img src="data64:..."/> in the DOM, just under the canvas (I think my canvas is transparent when it's getting viewed)..

(The thing is, I will need to set some headers,.. don't imagine you can generically do that, for instance, WebGL will give you Black image until you set a preserveDrawingBuffer:true option XD)

I might try that ASAP, I hope I won't spam you too much with all the DOM that will get generated 😅

Thanks for the summary @gre. This is indeed a tricky task, and I can't promise if/when we'll be able to fix it, as we have so many other pressing tasks on our list.

Whatever we do, we'll be sure to keep this issue updated :)

sorry I updated my comment :D do you think it's ok for you if I try my "base64 hack" ?

[gre]

yeah, no problem! i'll wait :)

Is it considered bad form to bump a feature request? I'm only mentioning this because using Scrimba to teach the canvas and animations to a high school class would amazing. I recorded a lesson only to find out the hard way that this was an issue... 3 years ago.

Hi, we unfortunately won't add this in the near future, as it's not a critical feature for us, and we have very limited resources.
