Can a Morph / (etoys player) follow a connector path ?
by Mike Stramba 18 Mar '12

18 Mar '12

I'd like to do something similar to this game in Squeak / Etoys http://www.gamenet.com/game/air-traffic-chief/ I.e. using a connector, having the motion of a morph follow that connector, as the connector is moved while the morph is moving. I see the demos in Etoys of a "car following a road", but they seem to be tracking a particular color, and continually turning left or right (which is ya, basically what any path finding program is gonna have to do internally, I guess). Wondering if there is a "high level" / class / etoys .. method etc, to track a connector Mike

[ANN] Ideas for this year GSoC wanted
by Janko Mivšek 18 Mar '12

18 Mar '12

Dear Smalltalkers, Let we apply this year again for the Google Summer of Code, which as you know is a Google's stipendium program for students to encourage them working on open-source projects [1]. Ok, our first step as community is to collect ideas for possible projects and to apply to the GSoC as an organization. Deadline is next Friday, so please hurry on with ideas. Just put them as reply to this email or to admins directly and we will put them on our website [2]. Your project idea should be written as answers to these questions: Name Level (Beginner, Intermediate, Advanced) Possible mentor Possible second mentor Description Technical Details Benefits to the Student Benefits to the Community See how such ideas look like in past: http://gsoc2010.esug.org/ideas. Waiting for your ideas Carla and Janko, your GSoC Admin team [1] http://www.google-melange.com/gsoc/homepage/google/gsoc2012 [2] http://gsoc2012.esug.org -- Carla F. Griggio, Janko Mivšek Smalltalk GSoC Admin Team http://gsoc2012.esug.org

GSoC proposal - Finish Physical Etoys port to Sugar
by Ricardo Moran 15 Mar '12

15 Mar '12

Hi, I don't know if there is still time to propose a project but, in addition to Steve's proposal regarding Physical Etoys support for Arduino LilyPad, I think this could be an interesting project for the Sugar community: =================================================== Name: Finish Physical Etoys port to Sugar Level (Beginner, Intermediate, Advanced): Intermediate Possible mentor: Ricardo Moran Possible second mentor: ... Description: Physical Etoys is an extension to Etoys that allows the user to communicate with robots as if they were virtual objects in the computer. With Physical Etoys, it becomes posible to program real world objects (such as robots) to perform any task you want, or sense the world and use that information to control virtual objects (such as drawings on the screen). The hardware platforms currently supported by Physical Etoys include: Arduino, Lego Mindstorms Nxt, Nintendo Wiimote, Microsoft Kinect, and others. Making Physical Etoys work in Sugar would bring a platform for teaching robotics to all Sugar users, letting each kid that owns a XO transform his laptop into a robot. The port is currently half finished, but it lacks some details that need to be taken care about in order to finally publish it. Technical Details: All Physical Etoys modules should work well in Linux and specifically in the XO laptop, this can involve porting some libraries and generally dealing with platform-specific issues. Finally, Physical Etoys will have to be wrapped as an Activity bundle for the XO. Benefits to the Student: The student will learn about the inside of Physical Etoys and its communication model with the outside world, making it work seamlessly in different platforms. Benefits to the Community: The Sugar community would gain a visual programming tool for teaching robotics that is based on a currently popular platform, as it is Etoys. =================================================== Please tell me what you think about it. Thanks, Richo

How to make a button in Etoys 4.1 update 2390 change color of a morph
by Mike Stramba 14 Mar '12

14 Mar '12

I'm trying to setup a simple etoys project with a playfield, button and rectange. When the button is pushed the rectangle should change color from it's default of black to red. 1)I've dragged out a playfield, button and rectangle from the supplies, placing the rectangle, and button inside the rectangle. 2) I opened a viewer on the button, and dragged the empty script to an empty place on the workarea (not in the playfield), then added a test tile, and a "button down?" condition to the test. When viewing the script textually it shows : ------------------------ script1 ActiveHand anyButtonPressed ----------------------------------------------------- 3) I then switched the button script back to "revert to tile version" 4) I opened a viewer on the rectangle, and dragged the 'Rectangle1's color' tile to the workarea, and tried to drop it into the Test / "yes" slot in the button's script editor, but it doesn't accept it. Do I need to use a variable (player type) in the button script to reference the rectangle's color attribute ? If so, how ? ----------------- I could do this same thing "manually" just using a custom class subclassed from morph, adding code to the handle down etc, but am trying to figure out how to using the supposedly "eaier" Etoys :/ Mike

sixteen items for Squeakland 2012 - item 9: ScratchConnect
by Ricardo Moran 10 Mar '12

10 Mar '12

> 9. Add Koji Yokokawa's ScratchConnect (game controls and game displays) > This will allow kids to create “game controllers” using Etoys Projects on > one set of computers to control a “game display” (another Etoys or Scratch > Project) on another computer. > > Hi, I've been looking at ScratchConnect ( http://www.squeaksource.com/ScratchConnect.html) and I think it would be cool if we can include it in the release. I think the code seems fine. Although it doesn't follow the Etoys pattern of adding methods directly to Player, I don't think this minor difference is important enough to fork it. The other problem is the license, I haven't found any info about it yet. Should we ask the author about it? Cheers, Richo

Translators needed
by Bert Freudenberg 07 Mar '12

07 Mar '12

Hi all, we rely on the infrastructure provided by OLPC / Sugar Labs for translating Etoys. Chris, who is leading the translation efforts, reminded me to call for volunteers helping to translate. I am forwarding his message below. Helping is easy: you simply go to http://translate.sugarlabs.org/ and pick some project and language, and start translating. If you want to get more involved, see the FAQ for how to subscribe to the mailing list etc. Developers can also help making the job of translators easier. Here are some tickets where translators have requested changes to Etoys that go beyond simple typos: http://tracker.squeakland.org/browse/SQ-950 http://tracker.squeakland.org/browse/SQ-695 http://tracker.squeakland.org/browse/SQ-681 http://tracker.squeakland.org/browse/SQ-680 http://tracker.squeakland.org/browse/SQ-675 We will not get all of these fixed for 5.0 (e.g. adding proper plural forms requires some real coding, and we are in feature freeze by now) but maybe some of these would really be low-hanging fruit ... Thank you, and please share this widely! - Bert - PS: Maybe you could even recruit a friend who is not involved with Etoys yet, but speaks another language than you :) Begin forwarded message: > From: Chris Leonard <cjlhomeaddress(a)gmail.com> > Subject: Re: [Localization] New Etoys strings > Date: 7.
