[ANN] New FunSqueak 6
by Edgar J. De Cleene 30 May '08

30 May '08

I put a new FunSqueak3.10alpha.7.image. To list of previous packages, I add: Scamper. Celeste. InstanceEncoder OSC To web team , please update the info and links. http://ftp.squeak.org/various_images/FunSqueak/FunSqueak3.10alpha.7.zip To Stephanne Rollandin, I put all prerequisites Musical Objects need, still polishing details for having a small part of you super work into the image, hope I could do for the next . RePlugin is specific for each OS, so each need download and put into the right location. Maybe could be replaced by Vassily Regex , slower but only Smalltalk ? You tell me. I put the relevant updates of 3.10.1 into and set the depth to 32. Add the WelcomeWindow of 3.10 and the history of 3.10, remove Rosario photo and SSI photo of New Worlds of Squeak project to request of Serge. Enjoy and send feedback Edgar

Flaps

I don't like them currently. I turn them off and turn on the mainbar. I find they tend to clutter the real estate and don't really offer me any additional functions that I can't get through the menu or a workspace. Am I missing something?

Sound

I am trying to use the 'sound' widget. I get an error 'primitive has failed' Where do I go from here? I am using Ubuntu 8.04 and can use recording and play in 'Praat speech analyser' so my sound system is working in Ubuntu but can't get any sound in Squeak. The Movie Player also fails. I am using Squeak 3.9.

Chess AI
by Ryan Zerby 27 May '08

27 May '08

Is there still an official Chess package for squeak? I know there's on in croquet and there used to be one in the squeak distro, but I don't see it any more. I have created an AI framework in java and am interested in porting it to squeak, but would prefer using the existing standard as my basis, for the usual reasons.

Video/Graphics, per pixel
by Ryan Zerby 27 May '08

27 May '08

How do I go about doing perpixel manipulation (both read and write) of an image? I'm interested in doing some computer vision work in squeak as well. I find that Java on a 800Mhz PIII is fast enough to give me a reasonable frame rate on a 320x200 webcam... I'm hoping squeak will have at least the same performance as well as being better for development.

SAR Files
by Jeffery Billing 27 May '08

27 May '08

I am interested in using the 'Speech' package. These are in SAR files. How do I convert these files and then install them into squeak (vers 3.9) so that I can use them in a project? I am a complete newbie!! Jeff Billing

Re: [Newbies] My first program. Design/style advice requested.

Well, the obvious thing to do is not to have separate classes for each side. Instead have one class, and have one instance per side. Probably have each controller decide what to do, or perhaps even better, have a single controller that delegates to the appropriate instance depending on whose turn it is (and orchestrates the transition from setup to play). That way you won't be duplicating functionality, or spreading around logic about the flow of the stages of the game.

My first program. Design/style advice requested.
by peter h meadows 26 May '08

26 May '08

Hi. I wondered if anyone could take a look at my code and answer some questions. I'm trying to write a program that lets people play Arimaa (Arimaa is a board game that can be played with a standard chess set. You can find the rules at arimaa.com but you won't need to know how to play to understand my code) My code is on squeaksource: http://www.squeaksource.com/Arimaa.html I run it by: ArimaaGameZone new openInWindow . Click on the last two rows to position white pieces, then press the send button. Then click on the first two rows to position the black pieces. The move logic is not yet implemented, but I'm sure you get the idea of what I want to do. I've tried to use a MVC design where ArimaaBoardMorph is the View, ArimaaBoard is the Model and ArimaaEventHandler is the controller. So I have a different class to handle gold setup, silver setup, gold move and silver move (in arimaa we have gold/silver instead of black/white). All inherited from the ArimaaEventHandler. The board morph sends a message to the controller and depending on which controller is set you get different behaviour. Is this the best way to do what I want? I think it's probably wrong that when I switch between controllers I have to copy the variables that contain the model and the view. How should it be done with good smalltalk style? Is there a simpler way? Is it right to use inheritance as I have done? Any comments on other aspects are most welcome, but my main question is; have I done the MVC thing right? Don't be afraid to say it's all wrong, this is my first project and I don't mind rewriting the whole thing from scratch. I realise helping me with this may take some of your time, and I am very grateful for any response. I hope I will stick with squeak and one day do something useful for the community.

Re: [Newbies] Remove old instances of a Class
by Claus Kick 26 May '08

26 May '08

why not just do MyClass allInstances do:[:i | i := nil]. Smalltalk unusedMemory. (Cannot recall if unusedMemory triggers a GC in Squeak, or even exists). Anyways, the first should nil all of your instances and then get them gc'ed. -- Claus Kick "Wenn Sie mich suchen: Ich halte mich in der Nähe des Wahnsinns auf. Genauer gesagt auf der schmalen Linie zwischen Wahnsinn und Panik. Gleich um die Ecke von Todesangst, nicht weit weg von Irrwitz und Idiotie." "If you are looking for me: I am somewhere near to lunacy. More clearly, on the narrow path between lunacy and panic. Right around the corner of fear of death, not far away from idiotism and insanity."
