Tetsuya HAYASHI made a cursor that allowed you to access polygon vertices one at a time. That vertex could be moved via the scripts. It is in the OLPC version. I made a version of code that combined what he had done with my polygon work and submitted it to Yoshiki Ohshima for inclusion in OLPC. For some reason I didn't get correspondence back (this was around the beginning of the year). As far as I know my work did not get into OLPC. So the basic answer to your question is yes it would be doable. And I am willing to assist. The other part of it (the scripting part) needs understanding of stuff I am not familiar with so someone on the squeakland side of things would have to be willing to assist with that. Thanks for your interest and comments. Yours in curiosity and service, --Jerome Peace ____________________________________________________________________________________ Expecting?

Hi, My 6-year old's favorite object is the "MixedMorph" in Squeak 3.9 because of the way it handles like putty. She uses it to create all kinds of shapes and pictures. She misses it in Squeakland plugin image. Will MixedMorph make it into the Plugin image? Regards .. Subbu

[Squeakland] MixedMorph for kids Hi Subbu, There is a ear to ear grin across my face as I read your daughters comments. The enhancements I made to polygons that lead up to Mixed Morphs would work in 3.8. I don't know who is maintaining 3.8 or the squeak plugins. If they contact me I would be happy to assist getting my work backported. The basic code is on Bob's superswiki at: http://209.143.91.36/super/700 I want to see what kids would do if let loose with these things.

Thanks. > You can get > much of the same from a regular PolygonMorph but not the mix with smooth > and segmented outline, For a kid, they are very different 'stuff'. Mixed feels like working with dough while Polygon is like working with sticks. Since Polygon is a subclass of Mixed, I changed PolygonMorph to MixedCurveMorph in SketchEditor>>polyNew: method and painting shapes (like spades or heart) is so much easier. It will be a good addition to SqueakPlugin. Regards .. Subbu

Croquet fails to initiate OpenGL
by Eric Eisaman 08 May '07

Croquet fails to initiate OpenGL on all my computers although OpenGL is installed and updated. Also, my Win32 platform seems to have no good source of entropy and is generating a security warning. Any advice is welcome. Eric Eisaman

Hi Eric -- The Squeakland list is about Etoys and is for school teachers and parents. The Croquet list is at opencroquet.org and the Squeak list is at Squeak.org.

Help for getting BotsInc on ODLP
by stéphane ducasse 01 May '07

01 May '07

Hi all I was discussing with Bert about getting botsinc running on ODLP. The environment is really small it is 17 classes. And this would be great to have an environment to teach Smalltalk on it. Apparently Bert told me that Alan would be interested and that I should send an email to this mailing- list. So this is what I'm doing. Now I need help. I have a bug when I put a self halt in the method that is executed. Ned told me that it could be easily fixed but right now I have no time and I got already burnt in the pas with concurrency and morphic. So I would like to know if somebody is interested in helping me. square "self square" self north. self go: 200. self halt. self east. self go: 200. Does not stop the bot and its animation. (I have an older version not based on the rewrite that Ned did for me but based on morphic wrapper that is working correctly but I would prefer to use the last one since I developed further and it is in sync with the book). I was working on a better history of commands. Now there is also a problem of how to save script. I proposed to save categories but may be we need something better than that. I'm working on releasing extra chapters (with Lsystem and other). I'm working also on releasing another micro world with a robot (looking like Karel with really fun exercises). These extras chapters will be freely available. But all that takes time. On a 3.8 image On SqueakMap load shout.4 (this is not necessary and we can remove it after, it just gives a better feedback on errors).
