[Sugar-devel] My application idea : chess learning software. What do you think ?

[laurent bernabe]

Hi,

First, I apologize for the length of this mail.
______________________________________________

My new idea (I've already exposed it on the mailing list, but without all
specifications) :

I think about making a new Web activity : a kind of chess learning software
series.
So, the first program I would like to code is about the pieces moves.

How could it be presented ? I am thinking of the following pattern :
For each piece kind :

   - the theory part (special organization for the king, who can't be left
   in check) : where I use the board, if possible in a smart way with arrows
   (and why not animations if I can).
   - the quizz part : where an alone piece is placed randomly on a square
   (special organisation for the pawn, which can't be neither on 1st rank nor
   on the 8th), and the student is asked if it can move to another square.
   - the practical part (If I manage) : where this time, the piece is not
   alone, and the position is a valid position.

Sound ambitious, doesn't it ?

Also, I don't want to rely on GCompris software, for several reasons :

   - I would like to manage software from my own, though GCompris offers
   some common features.
   - I discussed with the GCompris maintainer, and he said me that GCompris
   chess programs rely on GNU chess engine.
   - Finally, I want to write my program as a Web activity.

Advices request for Javascript :

Also, I have encountered problems with Javascript for making classes,
particularly for managing fields visibility :

   - I know that var keyword help make them private.
   - But I also know that, if I make them in the constructor, the
   constructor will be the only function that will be able to access them.

So that makes me into trouble, as "I come" from a more POO language as Java.

So how can I deal with it ? I've looked over Prototype library, but I
haven't seen any talk about the fields visibility in the documentation.
