Scratch

You don't.
On a project, you mean?

ON a project is it possible to make a varible/list which tells you how many scratchers are viewing the project.

No.

Yes, actually, because i want to create a game where you play with all the online scratchers.

If that is possible then yes

This isn't 100% flawless, but these scripts will work. First, make 2~3 variables and two lists:

Variables:
(Cloud)Timer*
(Cloud)Timer-
Memory//Opptional

List:
(Cloud)Online
(Cloud)Anonymous

Here are the scripts:

when gf clicked
if <not<(user ID) = (0)>>
 add (user ID) to [online v]
 if <(timer*) = ()>
  set [timer- v] to (0)
  delete [all v] of [online v]
  delete [all v] of [Anonymous v]
  add (user ID) to [online v]
  set [timer* v] to [-]
  wait (3) secs//Time for cloud variables to update. 
  set [timer* v] to (item [any v] of [online v])
 end
else
 add [User] to [Anonymous v]
end
forever
 if <(timer*) = (User ID)>
  wait (.98) secs
  change [timer- v] by (1)
  if <(timer-) = (8)>//The delay between updates. Adjust it if you want.
   set [timer- v] to (0)
   delete [all v] of [online v]
   delete [all v] of [Anonymous v]
   add (user ID) to [online v]
   set [timer* v] to [-]
   wait (3) secs//Time for cloud variables to update. 
   Fillet.//You might have to edit the 2 to make this work.
   set [timer* v] to (item [any v] of [online v])
  end
 end

when gf clicked
forever
 if <(timer*) = [-]>
  if <not<(user ID) = (0)>>
   if <not <[online v] contains (userID)>>
    add (user ID) to [online v]
   end
  else
   add [User] to [Anonymous v]
   wait until <not <(timer*) = [-]>>
  end
 end

when gf clicked
forever//Use this script or...
 set [memory v] to (timer-)
 wait (5) secs
 if <<(memory) = (timer-)> and <not <(timer*) = [-]>>>
  set [timer- v] to (0)
  delete [all v] of [online v]
  delete [all v] of [Anonymous v]
  add (user ID) to [online v]
  set [timer* v] to [-]
  wait (3) secs
  set [timer* v] to (item [any v] of [online v])
 end

when gf clicked
forever//…this script.
 if <(ping) = [true]>//Replace with what you'll use to detect…
  Fillet.//…when you're rechecking who's online. 
  Fillet.//For example, you might use a button.
  if <not <(timer*) = [-]>>
   set [timer- v] to (0)
   delete [all v] of [online v]
   delete [all v] of [Anonymous v]
   add (user ID) to [online v]
   set [timer* v] to [-]
   wait (3) secs 
   set [timer* v] to (item [any v] of [online v])
  end
 end

The third script might not work if the delay for updating cloud variables is big enough, in which case you'll have to use the fourth script in place of the third. Also, once you've implemented this script, the list Online should become which scratchers are viewing your project and the list Anonymous should be the non-scratchers viewing the project. Add their lengths to get how many people are viewing your project.

I hope that this helps!

What is user id's initial value?

Used ID is a new variable in Scratch 2.0 that reports the viewer # of a viewer, except when the viewer isn't a scratcher, which then it reports 0. So in other words, user ID's initial value is preset for you.

No. Why do you ask?
