RFC Minecraft Server
by Ben Coman March 12, 2016

March 12, 2016

I'm not ready to do this yet, but just surveying interest. I'm thinking of creating a Minecraft server using Pharo. My kids are enthusiastic about playing Minecraft and I think its a great platform to grow their creativity and cognitive skills per [1]. Much better than passively watching TV! [1] http://minemum.com/minecraft-educational I'm particularly interested in using Minecraft modding as a platform to teach programming to my kids. I had high hopes for the Scratch-like interface of learntomod.com, but I found it awkward and unsuitable. Other options for writing mods include Java[2], Javascript [3] or Lua[4][5]. For now I'll probably settle on Lua, but I'd prefer to be teaching them with Phratch and later directly with Pharo. [2] https://blogs.oracle.com/arungupta/entry/introducing_kids_to_java_programmi… [3] http://scriptcraftjs.org/ [4] http://www.computercraft.info/wiki/Main_Page [5] https://book.cuberite.org/ Ignoring client-side modding that IIUC is only applicable to single player mode, mods are implemented on the server. Servers are written in several languages [6] and it would be nice to make one in Pharo, with Woden providing a basic 3D viewer as a management tool. Documentation available here [7] [6] http://minecraft.gamepedia.com/Custom_servers [7] http://wiki.vg/How_to_Write_a_Server cheers -ben P.S. Along the way I found several pointers at the following being competent info on optimising voxel engines... http://0fps.net/2015/01/23/collision-detection-part-3-benchmarks/ http://0fps.net/2012/01/14/an-analysis-of-minecraft-like-engines/ http://0fps.net/2012/06/30/meshing-in-a-minecraft-game/ http://0fps.net/2012/07/07/meshing-minecraft-part-2/

Re: [Pharo-users] Fwd: Fwd: Phratch + Debian
by jannik laval March 12, 2016

March 12, 2016

Hi Markus, I send the email to the pharo community. Can someone help us to create a phratch .deb package ? The need is for a french professor who needs to create a debian live distrib for education. He want to include phratch instead of scratch / snap ... So, it is a great opportunity for us. Thank you for your help.

Hi I was wondering what the status of NBOpenGL on Pharo5 was. As far as I know, it does not work.Â I would like to have CodeCity work on Pharo5. Is anybody else (for instance the Roassal3d team) affected by this? CheersRicky

OpenGL project
by Thibault Raffaillac March 12, 2016

March 12, 2016

Hi, I would like to do a bit of OpenGL in Pharo, but it does not seem to work at the moment. Tried NBOpenGL with a spur image (50560): _ fails at installation from configuration browser (need to click again on installing to get all classes) _ demo "GLTTRenderingDemo new openInWorld" fails at NBGLContextDriver with error "No suitable implementation found for initializing OpenGL context for your platform" (running on a Mac) Tried with a pre-spur image (50496): _ same weirdness at installation _ demo fails at NBGLCurveRenderer with "MessageNotUnderstood: receiver of on: is nil" Is there a working demo available out there? I have worked a lot with OpenGL ES 2.0 and could definitely provide work on the topic. Cheers, Thibault

Re: [Pharo-users] How to access XML tag name?
by Brice GOVIN March 11, 2016

March 11, 2016

Hi, according to what have found in the SAXHandler and XMLDOMParser class, you should use SAXHandler>>characters: method to get the information inside a marker. Information inside a marker is consider as an XMLString that is created after a call to XMLDOMParser>>characters:. I hope I helped you with your question. =) -------------- Brice Govin PhD student in RMoD research team at INRIA Lille Software Engineer at THALES AIR SYSTEMS Rungis ENSTA-Bretagne ENSI2014 22 Avenue du General Leclerc 92340 BOURG-LA-REINE ________________________________ De : stepharo [via Smalltalk] <ml-node+[hidden email]</user/SendEmail.jtp?type=node&node=4884099&i=0>> EnvoyÃ© : vendredi 11 mars 2016 13:37 Ã : Brice GOVIN Objet : How to access XML tag name? Hi Yesterday I started to hack a smart SAX handler. The idea is that I want to just specify the tags I want to visit and the SAX handler should invoke (generated) visit methods. Like that I can easily get visitors on XML domain. Here is an example of what I did. | h | h := SmartSAXHandler new visitor: (MyFilmVisitor new visitTags: #(FILM ROLE)); on: FileSystem workingDirectory / 'FILMS.XML'. h parseDocument. ^ h SmartSAXHAndler >> startElement: aQualifiedName attributes: aDictionary (visitor shouldVisit: aQualifiedName) ifTrue: [ visitor perform: (visitor createdVisitSelector: aQualifiedName) with: aQualifiedName with: aDictionary ] Object subclass: #GenericTagSAXVisitor instanceVariableNames: 'visitTag visitTags' classVariableNames: '' category: 'SmartXMLHandler' GenericTagSAXVisitor>>visitTags: aCollection "set the tags that will lead to a call to a visitTag:with: method in the visitor" visitTags := aCollection collect: [ :each | each asLowercase ]. self createVisitMethods. and in a subclass the visit* methods automatically generated Now I could not get when I have a <TITRE>Vertigo</TITRE> where I can get the Vertigo information. I redefined several methods of SAXhandler but without success. <?xml version="1.0" encoding="iso-8859-1"?> <FILMS> <FILM annee="1958"> <TITRE>Vertigo</TITRE> <GENRE>Drame</GENRE> <PAYS>USA</PAYS> <MES idref="3"/> <ROLES> <ROLE> <PRENOM>James</PRENOM> <NOM>Stewart</NOM> <INTITULE>John Ferguson</INTITULE> </ROLE> <ROLE> <PRENOM>Kim</PRENOM> <NOM>Novak</NOM> <INTITULE>Madeleine Elster</INTITULE> </ROLE> </ROLES> <RESUME>Scottie Ferguson, ancien inspecteur de police, est sujet au vertige depuis qu'il a vu mourir son collegue.

Hello, I'm a student at Lille 1 university, so I'm still a beginner in Pharo I'm working on Artefact to create a more understable and complete demonstration. To do that I would like to print the code of a given method. However I can find how to decompiled the given method. Any help is welcome. -- [image: --] Guillaume Ongenae [image: https://]about.me/guillaume.ongenae <https://about.me/guillaume.ongenae?promo=email_sig&utm_source=email_sig&utm…>

How to get GLMSystemWindow from GTPlayground
by Norbert Hartl March 11, 2016

March 11, 2016

I wanted to write a small utility snippet involving GTPlayground. I want to transfer all my playgrounds from one image to another image. Something like (GTPlayground allInstances reject: [ :each | each title = 'Playground' ]) do: [ :each | (each title asFileReference , #pg) writeStream nextPutAll: each entity content string; close ] The snippet depends on the window title. I think I've found a bug because in the menu "Change titleâ¦" does not change the title of GTPlayground but of the GLMSystemWindow it is associated with. I did not find the way to get the GLMSystemWindow from the GTPlayground in order to be able to access the title. thanks, Norbert

Gitfiletree on pharo5
by Norbert Hartl March 11, 2016

March 11, 2016

I tried a new pharo 5 image today and wanted to load my code via gitfiletree into the image but it does not work. I can see on the console that git commands are invoked and the output is to be seen on the console. It seems the image does not get the same information. I can remember there is an actual problem with OSProcess? What I find weird is the fact that if I start the image by hand from the shell I get a pager like less for the commit info gitfiletree likes to parse. The process hangs there and if I press q in the console it proceeds and throws an error in pharo because the stream was empty. Any thoughts? Norbert
