Hello and welcome, Yeah lots of programmers start programming willing to do video games. But a few finish by really doing games... When I was student (a year ago) I started to implement a game, and then I switched and I am now working in compiler & virtual machines related stuff. But recently I decided to fulfill my dream and to finish the game I started as a student. Some features are still missing, but the game is there : http://clementbera.github.io/amber/projects/easnoth/easnoth.html# This is done in Smalltalk. Not directly in Pharo, because Pharo permits to do client applications, and as a small game I prefered to have it on the web so I implemented in in amber <http://amber-lang.net/>, which could be described as a Pharo on the web. Good luck with Pharo. Any question is welcomed. Clement 2013/6/4 ÐÐ°ÑÐºÑÑÐ½ Ð ÑÐ·ÑÐ½ <mrizun(a)gmail.com> > Hi everyone! > My name is Mark and I'm new in Pharo community.

3D and Pharo - Blitz3D SDK & NB

by phil＠highoctane.be

Hello, As holidays are nearing for me (like 15/7-15/8), I plan to get the Blitz3D SDK working with Pharo through NativeBoost. All right, this is not OpenGL or anything like that, and will only work on Windows. But I do know the commands and how to use it, hence my choice. Anyone wanting to join me in doing this? Phil

Re: [Pharo-users] Fixing obsolete Classes

by Gisela Decuzzi

Yes I finally figure it out... the problem was that I have created shortcuts referencing this classes (before deleting the classes)... and in the KMRepository there were references to the class inside a block, it took me a while to realise that the reference was inside the block because you can't inspect a block and see the code. I had to reset the KMRepository (close my workspace window, because I have references to the old shortcuts) and that's it. Searching for strong pointers was a great advice to see who was using these classes.

Re: [Pharo-users] Fixing obsolete Classes

by Mariano Martinez Peck

Gisela, you can also get all objects in the system (#allObjectsDo:) whose "class name ='xxx". where xxx is the obsolete-version of the class name. Then you follow pointers... explore the object -> right button -> "explore pointers" or similar... cheers, On Mon, Jun 3, 2013 at 7:59 AM, Gisela Decuzzi <giseladecuzzi(a)gmail.com>wrote: > Hi, yes!

Hi, yes! Thanks for the help, searching it seems that I have shortcuts that has references to obsoletes instances, I will see how to remove them. 2013/6/3 Andres Valloud <avalloud(a)smalltalk.comcastbiz.net> > How can you have an instance of a class X if the class X doesn't "exist" > anymore?
