Awesome Cloud Clones!!! - Multiplayer Scratch Tutorial #3

Coding "Cloud Clones" in Scratch is achieved by combining Clones & Cloud Variables to create a MMO (Massive Multiplayer Online) experient that you can drop into any of your games using the Scratch Backpack.
In episode 3 of this Scratch tutorial series we code up use Cloud Clones to make the players visible. We expand to use 8 channels of cloud variables to communicate at scale And we figure out how players can leave (efficiently managing the remaining player slots).
Whether you're a novice coder or an experienced programmer, this episode will provide valuable insights and practical tips to level up your game development skills. Get ready to unleash your creativity and build the next generation of multiplayer games with Cloud Clones!

    The most commonly reported issue that followers have encountered is many clones being created rather than just one for a joined player. I will investigate your projects if you comment your scratch username below and share the project. If anyone had this problem and fixed it please comment below for others benefit! I will help as soon as I can :) but I believe the scripts as recorded are correct! 😅

    Great tutorial! Although I don't have much use for it at the moment I did find it interesting. I also have an idea for another tutorial, maybe a proper 3d tutorial instead of 2d raycast?

    Hello Griffpatch! Im a long time veiwer of your channel and i was thinking off turning this into a multiplayer drawing engine, ive been tinkering around abit but could not figure out how to send the pen lines over cloud data! if you could maybe make this as a branching off episode that would be amazing!

    @griffpatch is the best scratch teacher ever, change my mind. I just made a stop button detector. In my example, it says the id that left the game. The only time my method wouldn't work is if a player closes their browser.
