scratch-vm
Virtual Machine used to represent, run, and maintain the state of programs for Scratch 3.0
you'll get a character that animates forward, moving ten pixels per frame for three frames.
Scratch only updates the screen at set "yield points", which are basically any instruction with the words "wait" inside, and (more problematic) at the end of a loop.
This sucks. Loops should not have side effects! It's much more difficult to teach iteration when the unrolled version does something completely different!
But the problem is deeper than that—it pops up everywhere with basically every student I work with, because it prevents kids from seeing the results of their code! Two blocks in the same script which request a screen update should not be able to run on the same frame. (Unless the user has enabled turbo mode, which is already an option for advanced users who need to push the limits of the language.) I know that all languages have quirks, but this one really hampers Scratch as a learning tool.
I made a fork of Scratch which fixes this problem, but I'm not really sure what to do with it. Without a backend for saving projects to the cloud, I can't realistically use it in my classes. I've been trying to add a backend, but the code is undocumented and I have zero experience with backend development. https://github.com/LLK/scratch-vm/compare/develop...Wowfunha...
