[etoys-dev] Connect Etoys and Scratch

[Koji Yokokawa]

I'm sorry to be late reply. I was busy on Scratch Day in Tokyo.

Game Board idea is very interesting. Scratch can be connected with 
multiple clients simultaneously, so that it already can make 
multi-player games using multi-Etoys as controllers of the game.

ScratchClient Morph can also receive messages from Scratch and you can 
use them in the Etoys-way.
Scratch sends global variable changes as 'sensor-update' and broadcasts 
as 'broadcast' message to the clients. When a ScratchClient moprh 
received the messages from a Scratch, it makes a variable for 
'sensor-update' or triggers event named 'broadcast:'+message name for a 
'broardcast' message. Other morphs can read the global variables in the 
Scratch via ScratchClient morph variables in the ScratchConnect Morph. A 
broadcast message from Scratch can be used as an event in the Etoys 
event system.

Try to receive messages from Scratch.
And, please tell me ideas of using it to motivate children.
