Code a Multiplayer Scratch Game | JOINING | Episode 2

Continue to code our multiplayer Scratch game, we look at how to get 100+ players to join a single cloud game! In this second tutorial we will be looking at how to smooth our player motion using buffering lists, and how to allow any number of players to join our game even with only one cloud variable! Yes that's from 1 to 100+ players! Crazy right?

I still don't know what "mod" does :(

[@griffpatch]

It gives you the remainder after dividing by a number. So 4 divided by 3 is 1 remainder 1 ( because 3 goes into 4 once, and leaves 1). So 4 mod 3 = 1

[@star80doessdastuff]

remainder division basically, im pretty sure you learn it in 4th or 3rd grade depending where you are

[@SBZome]

@@griffpatch Oh, thank you!

[@peej10do91]

Man, Griffpatch you are just so kind! The way you talk so friendly and spend your time to help us is so heart-warming, you have grown so much and it makes me happy. A scratch youtuber with over a quarter million. It's amazing what you have done with scratch and all of the limits that you have pushed. You are a scratch prodigy and I've literally never seen a scratch youtuber smarter than you. I have been using scratch for 3 years and I consider myself a great coder but I am nowhere near your level. Thank you for providing us with amazing videos and content and I hope you live an amazing life! God loves you. :)

[@khushbufauzdar9880]

One question: You pick each player's UID randomly. So, it might happen that two or more players can have the same UIDs. Then what?

[@griffpatch]

It's incredibly unlikely to happen... Like so so unlikely. But to be absolutely sure we can either scan for in use IDs or encore the username & an id together

I have now started to learn C++ and am looking to continue my game development journey elsewhere. Thanks for all the amazing learning opportunities you have provided me with over the years. I will likely still watch your videos for the cool concepts and fundamentals you provide though. Thanks for everything!

[@umikaliprivate]

c++ really? stop right now! you're gonna regret this decision. learn something like go, rust, or even c instead. you're gonna spend nights trying to find that one memory leak, while with something like the rust borrow checker, you don't need to worry, it's just that rust has a very confusing syntax. c will definitely make the problem easier, and go is one of the best programming languages, because it has a great garbage collector, it's great for many things, the syntax makes sense, and is easy to read, I think you should learn go instead.

[@1-1_is_2]

I have now started to learn Python the snake

[@umikaliprivate]

@@1-1_is_2 yea, python is pretty good, just don't ever add 0.1 + 0.2 in python.

[@kplays_6000]

@@umikaliprivate There's nothing wrong with learning C++, as someone who has built my entire career on it. It's one of the most used programming languages in the game development industry - Unity and Unreal Engine are built in it, as are the vast majority of in-house engines and tools. If you want a serious game development career, you need to know either C/C++ or C# for Unity. Python is good, as is Rust, but you're more likely to use them as part of a toolchain or in general non-game software development.

[@umikaliprivate]

@@kplays_6000 yes, that is true, but sometimes it's definitely annoying to use.
