Hi Jannik,

Don't use the change/update event mecanism. This mean a lot of changes in your model.

Yes, this is what I understand :)

In DrGeo I use a simple loop to update the sketch, but i guess it is more complicated with Pratch as you have parallel threads. In the other hand, is the original Scratch implemented with change/update? If so why it is not as slow?

I don't know why, probably due to the evolution of Pharo. But, with JB we found some code that we changed: now it is really faster. It is integrated in Phratch2.0. We also saw a lot of other things to improve, it will come soon. Cheers, Jannik

Hi Hilaire,

Hum, probably this comes from there... Could you explain a bit more how to change it ?

Cheers, Jannik

For event, how is it developed?

I remember, when I started developing DrGeo I used the change/update event mecanism. Then I dropped it for a simple linear top/down update of the geometric tree model, it becames much faster after that.
