In case you were at all interested... I made a project on setting up and using MESH here so you are welcome to use that if you want! Although I think you summarised it pretty well! wink

Mesh doesn't let you program a project on two computers... it simply lets two Scratch projects interact with each other.

are you using Mac or Windows?

JAMBAMtheSLAM · 2010-09-16 17:23:11

I'm using mac. A PPC.

ScratchReallyROCKS · 2010-09-16 17:25:06

Okay, that's your problem. I had the same one a while ago. On a Mac you option+click instead of right-click.

JAMBAMtheSLAM · 2010-09-16 20:59:18

Oh, then never mind. It works!!!

gamemaker8 · 2010-09-24 13:07:51

so when im hostiing mesh on my laptop and my sistr is on hers, we will be able to see each and it will be like a multiplayer game?

Jonathanpb · 2010-09-24 18:03:24

If you've programmed it correctly, yes - remember, all Mesh does is let Scratch projects use each other's broadcasts and variables.

hey ive been doing every thing right... i think but i wont work for me. it says its connected and every thing but it dont work. i wont let me make a chat room or anything. sad

Jonathanpb · 2010-09-25 03:41:31

You can't just make a chatroom so easily - you have to actually program one. wink Remember, all Mesh does is let Scratch projects use each other's broadcasts and variables.

Why doesn't Lifelong Kindergarten just add Mesh to the Share menu in default settings? What could it hurt?

How to get Mesh

The easy way: Download Jens's Build your own blocks - it comes with Mesh, available nice and easily.
The hard way: You edit Scratch's System Browser to make Mesh available. Here's how (it's a bit complicated, so there are pictures):

1. Shift-click the R in the Scratch logo.

http://img59.imageshack.us/img59/2364/7 … e1shif.png

2. Select "turn fill screen off".
3. You will now have a white area at the bottom and right side of the screen. Click on the white area and select "open...".
4. Now select "browser".
5. Now you've opened the System Browser! In this place you can edit Scratch (see here for more stuff with the System Browser). Anyway: Go to Scratch-UI-Panes - ScratchFrameMorph - menu/button actions - addServerCommandsTo: .

http://img294.imageshack.us/img294/3599 … e5thes.png

6. Look down, and edit the "t2 ← true" to "t2 ← false".

http://img19.imageshack.us/img19/4559/7 … e6true.png

7. Right-click and select "accept".
8. Enter in your initials and click "accept".
9. Exit the System Browser.
10. Shift-click the R and select "turn fill screen on".

If you don't want to go through the process every time you want to use Mesh, you can save the System Browser so Mesh will stay available - Shift-click the R again and select "save image for end-user".

If you don't want Mesh anymore, just change the 'false' back to 'true'.

How to host and join Mesh sessions

A Scratch program that has Mesh available on it looks just like the un-edited Scratch program. But - what happens if you Shift-click Share?

http://img11.imageshack.us/img11/5997/7 … e7host.png

Ooh! Mesh stuff!
• Host Mesh lets you host a Mesh session.
• Join Mesh lets you join a Mesh session.

To host a Mesh session:
1. Click Host Mesh.
2. Done! Your IP address will show up - you'll see why in a bit.

To join a Mesh session:
1. Click Join Mesh.
2. Enter in the IP address of the computer that is hosting the Mesh session.

What if you want to join a Mesh session, but the person hosting the Mesh session forgot to tell you the IP address, and he/she forgot what the IP address is? He/she Shift-clicks the Share button and selects "Show IP address". The IP address will pop up like before.

A Mesh session can have more than two Scratch programs connected at once.

How to program with Mesh features

Programming things with Mesh is (almost) the same as with the ordinary Scratch program - after all, if you're not in a Mesh session it's the same, right? But when you're in a Mesh session, things get slightly different:
• Broadcasts are received on all Scratch programs.
• You can use each other's variables.

If you create a new broadcast on one Scratch program, it won't be made in the other. You have to make the broadcast on both Scratch programs.

To use variables from other Scratch programs, you don't find them at the Variables section - instead, you have to use the ([ ] sensor value) block. It's near the bottom in Sensing. To use it, simply select the variable from the drop-down menu - in a Mesh session, the variables from all connected Scratch programs will appear on the drop-down menu!

That's all that's different with programming in Mesh - program projects the same way, but design it for multiple people, and don't forget the broadcasts and variables!

Hope this helps you - and have fun with Mesh!

Doesnt work. I end up not getting meshes. :-(

Mesh is an experimental feature in Scratch that they didn't feel was ready to be released yet. When they think it's ready, they'll make it public.

Oh - when people refer to the developers of Scratch, they usually call them the Scratch Team. wink

That's odd... could you tell me every step that you did?

The server isn't big enough.

It's nothing to do with that... Nitezscratch was simply asking why Mesh isn't so nicely available (currently you have to edit Scratch's code to make it available). wink

You right click on the top part of the 'R' (the upper round part) in the word, 'SCRATCH' at the upper left hand corner of the screen.

You don't have to right-click anywhere. hmm

Ok, so do the projects have to be downloaded, and if Mesh works online, how do you activate it online?

The projects have to be downloaded - Mesh isn't available online.

Indytig10 · 2010-10-16 00:04:39

Okay, so I'm trying to use Mesh between mine and my brother's computer. We both have Mesh working, but it won't let us connect when we put in our IP addresses. We both have Macs v.10.4.11. The first 6 digits of our IPs are the same, but the last two are different. Can anybody help me with this problem?

Jonathanpb · 2010-10-16 00:14:54

I can't really answer without being able to see the computers - are you sure that you activated Mesh properly and used the correct IP addresses? Hmm... try turning your firewall off? The first time I tried Mesh, Firewall asked me if it should allow Mesh. (If you do turn your firewall off, make sure you turn it back on when you're done.)

Yes, that was exactly what I was saying smile
