Subject: Re: loading (partial) environments

Hello Stan,
To do what you need, here are two new methods of the SpaceModel class.
Just "File-in" the attached file in your image and save it.
The first method, called #exportAttribute:fromClass:, build a text file
named ClassNameAttributeName.txt in the "maps" subdirectory of your model.
The second one, called #importAttribute:fromClass:, read this text file
and reset the values of the corresponding attribute (and only this one !)
from the content of the file.
In the #init method of your model, you can add this instruction:
self spaceModel exportAttribute: #state fromClass: #Cell
And then in the #step: method of your model, you can use this one:
self spaceModel importAttribute: #state fromClass: #Cell
This will be included in the new kernel of Cormas2003, which is almost
ready (you can download the version from December 26 on the Cormas
web site).
Happy new year to everybody !
