Scratch

Well, you found my other topic. Hope it helped. 

By the way: I believe you can just ignore the client and just connect Scratch to the Server without any problem since all the mirror does is just take what Scratch sent it and send that data to the server.    Just make sure to change the server port to 42001 instead of 42002 ( I think )

BTW, what does this do?

1. You have to code the Mesh into the Server

You should learn a bit of Python before you start making things out of it. 

yeah, I should. just tell me a few things
1) I don't know where to put it in (I have an idea)
2) a windows server for...................

your example mirror, the one on the front page, I run scratch, then open the mirror, and all python does is opens, writes things too fast for me to see, and closes. I debugged it and found nothing wrong. Did I do something wrong there?

if only javascript had sockets.    it would make it possible for easy multiplayer 8(

comp500: That would be interesting to see, if you get one up, could you show it?

markyparky56: What do you mean? Having a Single Player Game on a server, you can save Data there and you can access it from any computer, but Single Player Games off-line can only be played on that computer. But I don't understand very much of what you are talking about.    Could you explain a little?

Yes but I would need someone to host it for me as i'm not giving out my IP address...

Though the server hasn't been set up for Mesh

I realize that, but I still call it a mesh.

javascript does. its in html5...

really? Could you please tell me what they are? I am WAY better at javascript then I am at python, and I don't even know what python is used for!!

I'm baaaack!
@magnie
I want to make a little program in Visual C#.  I dont know if you know any of it, but I can connect to Scratch, but I want to know how to send data to the remote sensors blocks in Scratch from Visual C#. How, in human words, do you do it in Python? Just say something like, "First, I create an aray, then set a variable, etc.". I'm sure it will be simaler to do in Visual C#.

You could try looking at the Remote Sensors Protocol on the wiki.
