Yep.
I Always wanted to make a “Virtual World” on Scratch… But i failed.
I Failed because of the 1-2 sec delay on Cloud Data.
Is there a mod/extension to avoid it?
I Know i can use NodeJS to create a custom server, but i don't know anything about JS.
Thanks for the help ^^

Well… I made a peer-to-peer extension for ScratchExt3 called “Mesh,” but it doesn't save between sessions. If all you want to do is talk to other clients, you can use it

That's… that's the third mesh extension out there .-.

What was the second? (I think FireBase mesh was the first)

Mine was first, actually. technoboy10's (the firebase one IIRC) was second, by several months, actually.

We're actually friends (or were, idk). He was mildly embarrassed when I pointed out his mesh was late to the party

i wish there was but yeah, there's mesh stuff that you can try out

I better make a fourth one for good measure.

Lol I thought you made Firebase mesh

Can confirm this.

The main difference between Firebase Mesh and Cloud Data is that Cloud Data allows for the use of variables rather than broadcasts. At one point I had a version of Firebase “cloud” variables, but it didn't quite work properly.

FWIW my mesh has both <3

Scratch is still deciding what people should and shouldn't do with cloud data…

FWIW, the lag on cloud data isn't *so* bad (unless you're connected via the https fallback, which only polls for cloudvar changes once per second…)

My round-trip times are ~220-270 milliseconds for a smallish amount of data, going up to ~330ms for a cloudvar containing 10000 digits - and that has to cross the pond several times (i.e. project running in UK to MIT, MIT to my custom cloud client in UK, custom cloud client in UK to MIT again, then MIT to project in UK again). That comes out to >12000 miles, so it's doing an average of better than quarter the speed of light, which is pretty decent considering there must be a fair bit of latency in there at various points in the journey.

You can test your speed here: https://scratch.mit.edu/projects/96491582/

If you're going to make a custom cloud client that's reasonably real-time, then you really need to receive the cloudvar updates pushed through port 531, rather than polling the varserver every few seconds to see if a cloudvar has changed.

I've made a modification to Dylan's python ScratchAPI which makes this possible - you can find it here:
https://github.com/Dylan5797/ScratchAPI/issues/3
(Note the code snippet I left there wasn't tested with his latest commit, but he should be pushing an update with it at some point today-ish.)

Port 843 or whatever is to negotiate Flash's policy file – the idea is that you can't abuse Flash's open sockets to, say, make a distributed email spamming application. It basically just serves a file that say “it's okay Flash, you can connect to me”

If you manage sockets yourselves, it doesn't matter :-)

(IIRC)

Wow, thanks for the help everyone.
I think i'm going to try Scratch Ext, idk

Well i would say, either have a mod that reveals mesh, or, the harder way, edit the scratch 1.4 programming so mesh is here on offline editor, then pull people towards getting the mesh connected to your mesh IP so they can start playing, also works from window to window, so be aware about it.
