Squeak for "profesional" games
by Lord ZealoN 06 Mar '06

06 Mar '06

Hi, i wanna start a project with a friend. This project will be a mmorpg (Musive Multiplayer Online Roleplaying game) and we have some questions. WE thought do it with php and mysql, but this system has limitations (3D for example). Now, i'm thinking in squeak (i'm learning it, and thinking in her object reuse) and, here are my questions and the introduction for the questions. Imagine, The game will be like a Town (for example). But each neighbor is a real guy (100 guys connected at the same time for example) with which you can chat, interact, take a walk, pilot an airplane etc... Now the questions Squeak - Squeak has a good continous develop? New features, velocity, etc..... -Squeak is focused only for educational app's? or for normal/profesional use? Game - Is factible do a game with this characteristics in squeak? Graphics - How works squeak with 3D graphics? - Exists any engine like crystalspace3D or Ogre for games? (load MD2 files, terrain, ODE etc..) - Is possible do a 3Dgame in squeak? Network - This game will be only online. Is factible the use of Seaside for do the game for web? - Will be Better a "squeak server"? Will be better use squeak plugin for browsers? - With squeak and seaside you can have sessions etc.. like PHP? The game will be for a friends and me, but, if the result is good, we will think sell it. In other thinks, we are thinking develop in amateur level, but with profesional level if is possible. Well, this is all at the moment, thanks a lot, and sorry for this maill too large and for my bad english-google-language-tools. Cheers.

Smalltalk consenseSources failes in 3.9a7006 (Paul Provoost)
by p.provoost＠rn.rabobank.nl 06 Mar '06

06 Mar '06

Hi all, I tried a Smalltalk condenseChanges and Smalltalk condenseSources on 3.9a7006. The condenseChanges went ok, the condenseSources complained that the changes file was within 100000 bytes of its limit. I was allowed continue, but then the process stopped with the error: Message pattern expected ->]] What can I do about this? BTW Squeak is growing very fast: imgefile 20 MB changes file 22 MB. A limit of 32 MB for these files seems to cramped nowadays. Is it possible to work around that limit?

http://ftp.squeak.org/3.9/Squeak3.9a-7006.zip Users of 3.9a-7005 are urged to use 7006 instead, as I made a (really dumb) error in TCompilingBehavior>>#binding which compiled wrong bindings in MetaClasses... leading to a nice and clean crash when calling newly compiled class methods that have a "super" in them... this is fixed in 7006. Image has been recompiled to make sure that no bad methods are left over. CHANGELOG -------------------- - fixed #binding - 0003249: Mac VM pops up debugger on every launch (InternetConfiguration broken?) - 0003246: In 7005 Getting objects from Object morph not behaving as expected. - 0003245: 7005: ProcessBrowser DNU Marcus

RE: About use of specific error
by Peter Crowther 05 Mar '06

> From: stéphane ducasse > In Java you > get really a lot of exceptions everywhere. The comparison is > interesting. Java has had exceptions since the language was devised. In Smalltalk, and especially in Squeak, exceptions are recent additions. I suspect the reason that Smalltalk error handling has grown up the way it has, with variants of methods that don't throw the exception, is because error: didn't give the option of handling the problem - your code simply failed. A Squeak exception hierarchy has not been constructed because we're still moving over from a 30-year-old legacy of throwing the user into the debugger rather than handling the exception somewhere in the call stack. - Peter

Squeak communicating with Linux robots
by Jason Rogers 04 Mar '06

04 Mar '06

I just read an article in Linux Magazine about Linux robots (http://www.linux-magazine.com/issue/65 and http://www.linuxrobots.org). The robot is connected to a network via an onboard WLAN card. You SSH into the computer on the robot, execute some C code (which hooks into the robot's libraries called 'librobot'), and botta-boom-botta-bing -- the robot moves. I thought it would be neat to write a layer that would translate E-Toy scripts into C in order to enable kids to control a robot from Squeak. However, I have no clue how to "export" E-Toys scripts. Maybe that is the wrong tack altogether. Perhaps all I need is a plugin or FFI that would interface with the librobot C code. Am I on the right path, or is it more complicated than that? -- Jason Rogers "Where there is no vision, the people perish..." Proverbs 29:18

http://ftp.squeak.org/3.9/Squeak3.9a-7005.zip CHANGELOG -------------------- 0001613: [ENH] truncatedChanges-ls Date: 4 September 2003 Author: Lex Spoon Handle truncated changes files more gracefully. The problem actually can happen, and has been observed at Georgia Tech, e.g. if someone downloads a file but does not complete the download. The current behavior is that pink debuggers pop up; this is extremely confusing for new users when it happens in places like the Browser. The solution in this changeset is to fall back on the decompiler. A more thorough solution should probably trigger a systematic invalidation of all source pointers past the end of the changes file, because as time goes on the changes file will eventually grow large enough to cover the lost code and the routine will start returning random method code for the invalid source pointers. ---------------- 0001354: MIDI port name is garbled in selection dialog Change Set: AddTransMIDIPort Date: 31 May 2005 Author: Tooru Nosse fix for query of MIDI portName with SJIS name enable translation for midi port selection ---------------- 0002341: MorphicEventDispatcher minor refactoring 0001284: Smalltalk condenseSources leads to UndefinedObject(Object) >>error: 0003180: Selector requester does not strip blanks tests from 0001798: #critical:ifError: on Semaphore does not always signal the semaphore test from 0003133: [BUG][FIX] Float>>#asIEEE32BitWord and #fromIEEE32Bit: ---------------- Change Set: dupAllCtrlAltKeysPref-dew Date: 13 December 2004 Author: Doug Way Adds a new preference duplicateAllCtrlAndAltkeys to duplicate all Ctrl and Alt modifier key commands, which causes all Ctrl key commands to behave the same as Alt-key commands. The original Ctrl (a.k.a. 'shift') key commands are still available via Ctrl-Shift and Alt-Shift. This differs from the existing ctrlAlt prefs which only duplicate/ swap the eight editing keys. Also includes code to prevent these other two conflicting prefs from being activated at the same time. The three related prefs (swapCtrlAndAltKeys, duplicateCtrlAndAltKeys, duplicateAllCtrlAndAltKeys) should really be made into a radio button preferences set sometime in the future (like the Halo look preferences), since only one can be turned on at a time. This would eliminate the need for the #changed methods. See 'modifier' discussion on squeak-dev from 12/3/2004 for more details on why this was provided. ----------- - postCopy for MethodProperties - Preferences panel size - remove Preference #ansiAssignmentOperatorWhenPrettyPrinting - remove Preference #resizeOnAllSides, #twoSidedPoohTextures - set selector when evaluating a #Doit.

Squeak in more than 8000 teachers and kids laptops, need for i18n
by Hilaire Fernandes 04 Mar '06

04 Mar '06

Hello all, For the second years, we will propose Squeak in the latptops the teachers and junior high school students receive each year in the French adminstrative area of Landes (SW of France). More info about this Laptop operation at http://www.landesinteractives.net/ (English version at http://www.landesinteractives.net/default.asp?cnf=2|) Each year the notebooks are remasterized, this year we would like to propose more Squeak components of interest for education as KEDAMA, ODECo, Connectors, etc. However we need to internationalize and translate in French these packages. The CDDP des Landes and the FSUG/ESUG can do this but we need to synchronize with the adminstrators of these packages because we need to modify the source code. In SqueakSource, I only found ODECo and its administrator Takashi Yamamiya. What about KEDAMA (Yoshiki Ohshima?) and Connectors? Who are the managers of these packages, we need to check with you to propose the modifications for mainstream. We have a page to keep notes http://community.ofset.org/wiki/CD_Squeak_pour_Landes_Interactives Hilaire Fernandes
