Ping other scratchers in real time!

You can send a ping to a Scratcher who is using this project in real time and they'll AUTOMATICALLY reply to your ping.

This is really awesome! How does this work?

ping | {sender_name} | {receiver_name} | {time of sending}

Whenever you send a ping, it encodes these values and sets it to a cloud variable

ping | {sender_name} | {receiver_name} | {time of sending}

and other people who are using the project, are constantly looking for cloud variables with their name as the receiver, if it's like that, then they send a pong back with same data, and we can calculate the delay. It currently is using 3 cloud variables.

So you're not able to send messages?

It sends a ping in milliseconds! This is the feature which I like the most. Vey fast!!!

Hey, couldn't a user clash occur? For example if there are 4 people on the project A, B, C, & D. A pings B and C pings D at the same time. Whose ping does it store?

You can still send unmoderated stuff through it - any user generated content is not allowed, maybe I could add premade phrases in an update coming this weekend . . .

B and C can never ping at the same time, this is a restriction put by the Scratch Websocket server, it can only send one packet of data at once.

So if B and C send it at the same time, the Scratch Cloud server will receive one ping before the other, and that will be sent to D's project first, and then the other.

I cannot prevent this as this is a limitation enforced by websockets and how scratch's cloud vars work.

No pings are stored, as soon as they're sent, a reply is received within ~600ms, and that data packet is no longer required. If the user isn't online, a ping will persist for a maximum of 3000ms (3 seconds)

A kind-of way to tackle this is by adding more variables, I added 3 now and it seems enough, the packet is first sent through a random var.

So if B and C send two packets via two different variables, both of them will be received. Otherwise if B sends is slightly before C, B's packet will be overwritten with C's data. That's kinda rare in my opinion, only a 33% chance of that happening given that 3 people are using the project at once.

But will it affect the speed of the ping?
