by Ariel Calzada 25 Apr '12

25 Apr '12

Hola Lista! Estoy intentando correr squeak para XO 1.75 ( Fedora 14 ), tengo problemas en cuanto a que tengo una imagen ( drgeo.image ) la cual al parecer funciona con una version de interpretador específica (6504) y la que viene para entorno es 6502. La verdad no conozco mucho de SQUEAK y por eso quisiera que alguno pudiera darme luces en el tema. Saludos, Ariel Calzada Activity Central

Animation question
by Christine Murakami 25 Apr '12

25 Apr '12

Is there a way to run an animation once, and stop after one cycle of holder cursors and not have it continually run? Thanks!

[Q] How to handle the script with many tiles
by Young-Jin Lee 24 Apr '12

24 Apr '12

Hello, As far as I know, the current version of Etoys (v. 4.1) does not support a scroll bar in the script box which makes it very difficult to add/edit tiles in the script when it already has many tiles. I am wondering how people deal with this problem. Is there a way to work around this issue? Any comments would be greatly appreciated. Thanks in advance. Young-Jin Lee

You can use Holders to handle "lists" in Etoys, Holders can store as many items (of any kind) you like. Then in the viewer look at the collections category. Stephen FYI, I generally reply to entire list as I find if one person has a question many others do as well.

[ANN] Physical Etoys 2.0 released!
by Ricardo Moran 22 Apr '12

22 Apr '12

Hi everybody (and sorry if you receive multiple copies), I would like to announce a new version of Physical Etoys, now with a lot of new features: 1. First of all, it's based on Etoys 5.0 so it incorporates all the bug-fixes and new features from the Etoys release. 2. We are now focusing on the two main hardware platforms: Arduino and Lego Mindstorms Nxt. For the rest, we will publish a set of "external modules" that you can install in your Physical Etoys version. 3. Also, we now support an argentinian version of Arduino, which is called DuinoBot and it's currently being used in a lot of argentinian schools. 4. We added new devices for arduino and now we also support the use of digital devices attached to analog pins. 5. We added two new objects that let you graph the input of a variable across time and save it to a csv file. 6. We added a new programming mode that lets you compile your scripts and have them running inside the robot, in contrast to running them in the computer and communicate with the robot via bluetooth or usb. We believe this opens a lot of new posibilities for the Physical Etoys users. 7. And finally, we fixed a lot of bugs that make the software a lot more stable (or so we hope :). I would like to use this opportunity to publicly thank all the people from the Etoys community for their work on Etoys 5, this latest version is much better than the last and I encourage you all to try it. And also, I would like to announce that Physical Etoys 2.0 is going to be installed by default on all the laptops of the "Conectar igualdad" program, which is kind of like the argentinian version of OLPC (but for older students). So we are *really* excited about this! Now that you're all as excited as we are :) you can download and try Physical Etoys 2.0 from our blog: http://tecnodacta.com.ar/gira/projects/physical-etoys/. Cheers, Richo

Hi, I was starting to grade the GSoC projects and I was surprised to find "Get Etoys image to run on CogVM" was not accepted. May I ask why? I was hoping this project would get elected. Best regards, Richo

Concentration game?
by Christine Murakami 11 Apr '12

11 Apr '12

I remember this coming up a year or so ago, but I don't remember the solution. I have a student who'd like to create a concentration-type matching game where the cards that don't match reveal an image temporarily, then "flip" back over. If they do match, then they stay revealed. She has been able to have a temporary reveal, but this could get really complicated with just a few pairs of cards. Thanks for your help!
