Could anybody help me with a game including a functional multiplayer system. This game is going to be like fortnite or surviv.io. It would also be nice to include real time fighting.

okay so cloud variables are required. cloud variables basically is data stored in the server. for example, everyone's x and y coordinates and if they're doing something or not.
You might also need lists

when I start as a clone
join the dark side of the force::#000000
switch costume to [stormtrooper]
forever
if <touching [lightsaber]?> then
delete this clone
end

This was really helpful! The techniques you used were really good, and also space-efficient (though, if you really wanted to, you could have the connection variable be 10 digits long and have each player change a digit.)

I understand the cloud variables for a players slot space. But I don't understand how i can have multiple players in one server without all being shown on another person's screen

You control what the project shows so it's in your hands!

That risks a cloud far being updated simultaneously by more than one player and data being missed. So you end up with a polling system which itself needs managing. That's why I prefer one cloud far per player.
