Understanding SnakeGame
by Filip Malczak 14 Jan '09

14 Jan '09

So we have a SnakeGame (you can get it with Wolrd->open-SqueakMap Package Loader). I wanted to look at its code to uderstand it, and learn how to write in Squeak (not syntax, but algorithms, etc). And so I have this problem: I know how to make the snake go, but where and how do I create gameboard? And 'New Game' and 'Quit' buttons? If anyone could explain me EXACTLY step by step how is the game going - I'd be very pleased. -- Greeting Filip GG: 2486889 mail: filet00(a)gmail.com

Getting HPDF to work on OS X
by Torsten Bergmann 14 Jan '09

14 Jan '09

Hi Stephan, maybe handing over a full path constructed in Squeak will help. I commited a new version HPDF-tbn.26 to the repository. Please tell us if it works on Mac. Bye Torsten -- Psssst! Schon vom neuen GMX MultiMessenger gehört? Der kann`s mit allen: http://www.gmx.net/de/go/multimessenger

squeak locks up on windows / help me debug it...
by Cameron Sanders 13 Jan '09

13 Jan '09

I thought the Pharo base image (3.10 with a few fonts & Balloon3d added) running on Windows was looking pretty stable (compared to other images). But after an hour of editing code on a Vista machine --an hour since the last save-Squeak has abandoned me. It is unresponsive. Trying both control and alt in combination with '.', 'l' (lower case L), 'c', does nothing apparently useful. The process stack reported by Vista shows it to be incurring page-faults like mad. [OK, that has subsided while I typed this email.] My machine has 4 GB of RAM, I am running two instances of internet-explorer, and I have turned off the Windows search-indexing service. I know Vista has a guess-the-next-program pre-loader that could be a little overzealous in displacing programs from RAM. but still. it seems like this 101MB program shouldn't generate any page faults when the other two leading memory pigs are using less than double that much virtual memory. Vista's Resource Monitor claims I am using only 43% of physical memory. The page-fault count for Squeak.exe doubled while I typed this message. When I click the Squeak icon on the window frame of the running copy (upper left on Windows), I do see the menu for VM Preferences. It shows me the menu and allows me to invoke actions. It will allow me to toggle the "Show output console" on and off. The output console shows me changes to memory (as I have that option checked). I can use my mouse wheel to scroll this console. Control-'.' and Control-c (and lower case L) in this console do not change anything. After mucking around in the console area, I am now getting "WARNING: event buffer overflow" just moving my mouse around in squeak. After turning the console off, the pointer is now invisible except when you click. It appears that the overall squeak window is repainting itself properly. -- Help me debug it I have an interest in building a commercial application in Squeak. The FAQs says squeak is stable. Given the active community of developers (including The Great Ones), I imagine that it is stable, and that I am just doing something dumb. repeatedly. However, for Squeak to be adopted more broadly, it can't go zombie on users, even when the user does something dumb. That's an absolute. What is the longest uptime a squeak image has ever endured (while doing something useful)? Which version was that and on what platform? So I am willing to work to help make squeak more robust, but as a complete newbie with it, I need much guidance. So right now, with this hung-up image, what should I do? Should I attach to it with gdb? And if so, then what? [If the internal process control is working, I won't be able to make heads or tales out of it from gdb, right?] Or can I launch another squeak and send it a signal in some way [is it listening?]? What is most useful in this case? [Is there a way in Windows/Vista to signal an app so as to force a core dump?] Thanks in advance, Cam PS: I want to emphasize that I do not care about the code lost in this particular instance (it was tutorial code), instead I am looking for a stable free development environment. and I'm willing to help make one. __________ Information from ESET Smart Security, version of virus signature database 3755 (20090109) __________ The message was checked by ESET Smart Security. http://www.eset.com

I would think synchronizing with SBE would make sense. I don't know what they are planning, but would guess they're waiting for the Pharo 1.0. Stephan

Resizing a form to specific width and height
by Matthias Korn 12 Jan '09

12 Jan '09

Hi, how can I resize a form to a specific width and height by either stretching it on one axis or cropping it on the other axis. I create the form with Form class>>fromBinaryStream: from a background image (.jpg) The messages in Form don't really seem to help or am I missing an obvious one? Thanks, Matthias

[Newbies] Resizing a form to specific width and height Matthias Korn matthias.korn at uni-siegen.de Sun Jan 11 23:16:02 UTC 2009 Matthias, If you have a 3.9 or later image look at ThumbnailImageMorph>>newThumbnail: for details. In building that I created a Point>scaleTo:(anExtent) method which returns a scale factor for the proper reduction of the receiving extent. It preserves the aspect ratio up to a certain limit then it will squash things a bit. Any morph can have a snapshot taken via Shift-clicking on the Viewer handle ( The Cyan handle with the eyeball icon ). Thumbnails can be shrunk or enlarged. And their red menu allows you to select a pop-up option. The pop-up option shows the original image while the mouse is held down on top of the thumbnail. I got the idea from Scott Wallace who may be better known for the Universe Package System. You may find the thumbnails are all you need. Yours in curiosity and service, --Jerome Peace >Hi, >how can I resize a form to a specific width and height by either >stretching it on one axis or cropping it on the other axis. >I create the form with Form class>>fromBinaryStream: from a background >image (.jpg) >The messages in Form don't really seem to help or am I missing an >obvious one? >Thanks, >Matthias
