Many of the “operating system” projects on Scratch are not really operating systems, but really fancy GUIs. An operating system consists of many low-level pieces, such as the kernel and bootloader. Scratch doesn't have such low-level capabilities, so you would have to write a virtual machine or emulator in Scratch that provides things like RAM, then write the operating system in the instruction set of the emulator. The whole idea is pretty ambitious - be careful not to choke on your aspirations.

Thank you for the answer, I won't make a real OS though. (As it seems it would be too complicated.) It will be more of a simulator that has an OS feel.

What, um, does an OS “feel” like?

I might of worded it incorrectly, I meant more like to give the player a feeling that it's an OS. Which will be hard to achieve.

when I receive [desktop v]

broadcast [Appearing Apps v]

when I receive [Appearing Apps v]

show

what everyone else is saying that would be very hard is a OS emulator. If you were to make an emulator it would simulate a CPU and RAM then run the OS on top of that

when green flag clicked

set [ runtime] to [0]
show variable [ processor power usage]
set [ processor power usage] to [0]
hide variable [ loading %]
hide variable [ Bios]
switch backdrop to [ Black Screen]
wait (.5) secs
broadcast [ message1 or whatever you choose it to be]

that is what I use for my Scratch os's to start the loading runtime, now to get into the loading part

when I receive [ message1]
hide variable [ Bios]
switch backdrop to [ startup1]
wait (1) secs
switch backdrop to [ startup2]
set [ loading %] to [0]
show variable [ Loading %]
repeat (100)
wait (0.01) secs
change [ Loading %] by (1)
end
if <(Loading %) = [100]> then
wait (0.7) secs
hide variable [ Loading %]
wait (0.2) secs
broadcast [ LOGIN]
end

That's how I do that.

Please create a new topic--this one has been dead since 2017!

this code is for whatever score you have

when green flag clicked
forever
play sound [whatever sound you have v] until done
end

this is for the shop sprite
when this sprite clicked
broadcast [show v]

now create a shop Title Screen sprite
and use this script for it
when green flag clicked
hide

when I receive [show v]
show

when this sprite clicked
broadcast [hide v]
hide


now make whatever sprite that makes YOUR score go up by random numbers.

when green flag clicked
show

when this sprite clicked
change [YOURSCORE v] by (pick random (2) to (3))

when green flag clicked
set [YOURSCORE v] to [0]

when [1 v] key pressed
wait (0.4) secs
change [YOURSCORE v] by (pick random (2) to (3))

And then yeah, you can add anything in the shop, or not have random numbers. Have a nice christmas!!
