Really? I can think of many reasons why other methods of doing multiplayer are a lot more powerful.

Connect mesh with a second window.

Can you do it on 2 different computers with the other methods? I think not. I rest my case.

Someone mentioned a drawing program with Mesh — I made one here.

I have a question - Would people have to download my project into BYOB, or onto Scratch?

They could use either, as long as they have Mesh enabled on Scratch.

Cool tutorial! It was working fine for me until I got to the  "Right-click and select "accept" part. I'm on a Mac, so I control-clicked, but nothing happened.

Command click

You right-click on the white area that appears when you Shift-click the R 

And sorry for the late reply, I should really check Advanced Topics more often ^^

Also, can a scratch project connect to a BYOB project or a panther project via mesh?

Yes.

I see a few people are having trouble with the mac right clicking, but I have found a solution  ! Go to the bottom section of the browser, and on the left, above the scroll bar, there is a minus button. Click that, and you will see "accept (s)" somewhere towards the bottom.

Hope that helps, it sure did for me!

Thanks for pointing out the minus button.  I could not right click to get to the accept changes on my Vista machine. The minus button is what I needed.

The tut works fine otherwise.

Thanks to everyone for the great info and hard work.

So, say I wanted one program to mesh with another of the same project, just running on a different computer, how could I make it so that on one project the arrow keys do one thing (the one that has joined) and on the other the arrows do a different thing?

Use these scripts to test connection:

when i receive [connect 1 v]  
set [connected v] to (1)  //first assume connection
if <(me) = (1)>
   broadcast [connect 2 v] and wait  
end
set [connected v] to (0) //only if the other script doesn't wait


when i receive [connect 2 v]  
set [connected v] to (1)  
if <(me) = (2)>
   broadcast [connect 1 v] and wait  
end
set [connected v] to (0) 

When one of the above two scripts is activated, it will check if the "me" variable is equal to one or two. Then it calls the other script, which will interrupt the first one waiting for the second one to finish (if it is in the other version of the project (the only way the "me variable to be different)), and wait for that script to finish, which if it still connected will interrupt the other script which will interrupt the first script.....
But if connection is lost, there will be no script to interrupt it, meaning the connected variable gets set to  0.


To set the "me" variable to the right value, use the following script:

when green flag clicked //or any hat
ask [Are you player 1? or player 2?] and wait
repeat until <<(answer) = (1)> or <(answer) = (2)>>
   ask (join (answer)[was not an option. Pick either 1 or 2.]) and wait
end
set [me v] to (answer)
repeat until <(connected) = (1)>
  broadcast (join [connect ](me)) 
  if <(me) = ([me v] sensor value)>
     say [Oops! Your opponent selected the same number! Press space to change player.] 
     wait until <<key [space v] pressed?> or <not<(me) = ([me v] sensor value)>>>
     if <key [space v] pressed?>
        set [me v] to ((3) - (me))
        say (join (join [You are now player ](me))(.)) for (1) secs
     else
         say (join (join [Other player changed. You are still player ](me))[.]) for (1) secs
     end
  end
end
forever if <(connected) = (0)>
   say [Connection error.] for (2) secs
   stop  all
end

when i receive [something v]//scripts where each player should do something different
if <(me) = (1)>
  stuff that player 1 does, not player 2
else
  stuff that player 2 does, not player 1
end

Hi, I'm using Ubuntu Linux 9.04 and every time I try to save after activating Mesh it freezes and I have to force quit Scratch! Any ideas? 

Ubuntu 10.10, same thing.
When I try to save the image, the top-left of a error window comes up, no other parts of it, and nothing responds.

CANT GET THIS TO WORK    why WHYYY!!!!
