Hi, if you are looking for strings like earth.software.umn.edu, there might be a menu item "Search for Method Strings with it". I don't know about croquet, but in Squeak image I can select the text earth.software.umn.edu and then right click, to get a context menu that contains "Search for Method Strings with it".

CCPainter actually does allow for the loading of existing images... Here is what David Faught has sent me in the past for replacing TPainter with CCPainter. http://www.nabble.com/CCPainter-to13039374.html#a13039374 .. and others that may help - http://www.nabble.com/forum/Search.jtp?query=CCPainter&local=y&page=0&forum=14182 It works very nice. rich -

trying to use Croquet for a new language learning project

Scott S. Lawton — 2008-07-24T17:46:37

I run a small company that is in the middle of a new project to create software tools to help kids age 6-9 learn a second language. I realize that Croquet is pre-alpha, so problems are to be expected. Still, I hope the base is solid enough that we can create some great demos. I hired a summer intern who has been learning Squeak and going through all the Croquet tutorials, but we are stuck on several issues. Dan has outlined them here: http://vcosm.com/croquet/ Some help would be greatly appreciated. In return, we're happy to write up the details of what we learn, e.g. turning our questions into mini tutorials and sharing general-purpose code. Briefly: - if we start from an existing world and make a few changes, how do we save them? Here's the exact steps we tried; http://vcosm.com/croquet/ChangeExistingWorld.html - what's the best way to create a new empty world? We tried invoking BaseWorld from Squeak: http://vcosm.com/croquet/CreateEmptyWorld.html - after we drag a JPG into a world, how can we turn it into a static object (without the manipulation frame)? How can we save it in the world? http://vcosm.com/croquet/AddAPicture.html - TPainter is cool ... can we load an image (or edit a JPG that we dragged into the world)? Where in the source code should we look to try to enhance the 2D-to-3D conversion? (which is a nifty feature BTW). http://vcosm.com/croquet/UseTPainter.html Help on these issues would be a great start, though we have a few misc. questions here: http://vcosm.com/croquet/OtherQuestions.html Thanks in advance, Scott

I am back to solving problem 3 now, it was left alone for a while but becoming a crucial part now as the tree menu is used oftenly. My problem is after clicking the tree view menu, the keyboardFocus is set to the tree and all key events will not be forwarded to the harness anymore. There is a releaseKeyboardFocus method in CTreeWidgetCostume which gets called in the method onMouseLeave but it just seems to release the focus. How do I set the keyboard focus back to the harness so that key events can be forwarded to the harness again? Andreas Raab wrote:

Hi Serge, I have seen your mention to a project about observation robots for GIS applications. I have been involved in something similar in a project for pollution control at Università Cattolica di Brescia, where we plan to use an approach based on neuro fuzzy technology based on a framework (FuzzyWorld) which I developped in Smalltalk and that I was thinking to port to Squeak. Can you give me some further details about your project ? Maybe we could find some synergies Thanks Ciao Lorenzo ----- Original Message ----- From: "Serge Stinckwich" gmail.com> To: "Baveco, Hans" wur.nl> Cc: duke.edu> Sent: Tuesday, July 22, 2008 3:20 PM Subject: Re: [croquet-dev] Re: [ANN] first version of CroquetGIS Thank you Hans for your explanation.

Our kids use CBModel Pro .. export as .obj from CBModel Pro ....

Hey Sjaak! You wrote: There is a working version of a VRML-Importer in the "hedgehog" monticello respository. If your models are of VRML without PROTOs, sensors and scripts, then chances are good to see them inside a Croquet world :) If you like to load VRML models into "Cobalt", then there is a modificated version of "CroquetMenuWorld->actionImport" in the Mantis bug tracker, which let's you load VRML models with Cobalt's menu option "Things/Load from file..." I had some nice results with coloured "materials", but couldn't get textures to load. Cheers... Thomas Braun

acquiring reference to TSpace in which a squeaklet is embedded

2008-07-22T15:45:22

Hello all, I have created a squeaklet which I import into the "MPEG Demo (Master)" world. I would like to have the squeaklet's processing take into account the state of the world in which it's embedded (particularly information about avatars that may enter the world). My initial research suggests that I need a reference to the world's TSpace object - how can I obtain this? If I'm going about this the wrong way, other suggestions are very welcome! Thanks for any thoughts. cheers, RHH

3D model importers

Sjaak Wolff — 2008-07-22T09:31:21

Dear Croquet developers, I am a student at the University of Leiden and i am working on my bachelor project. My idea was to implement an existing image/3dmodel bio-informatics database in croquet, where several users can 'walk through' the database and can look at the images and models that are in it, discuss, annotate and do whatever with it. Ive come quite far now with the implementation, however, im having difficulties with loading 3d models into the croquet world. There is an example tutorial on www.opencroquet.org where some .obj files are imported (they are accompanied by .mtl files) which works fine (SanMinimum Island). But when i tried to import some random .obj files from the internet the system hangs :( I was hoping i could get some help/tips on how to get a working .obj / .vrml file 3dmodel importer for croquet. Yours sincerely, Sjaak Wolff (sjaakwolff< at >hotmail.com)

Re: error with code > 1 Kb

Andreas Raab — 2008-07-21T17:01:50

I'm not sure about all the reasons but one limit that comes to mind is the conditional jump bytecodes. They are limited to the range -1023 to +1024 (IIRC) so the VM doesn't know how to execute jumps beyond these limits. You send messages. In general you cannot get access to another object's variables unless that object allows it by providing accessor messages. In Smalltalk all object interaction is based on message-passing, there simply isn't a way of accessing another objects variables directly. Cheers, - Andreas

Re: error with code > 1 Kb

Rafael Rojano — 2008-07-19T18:08:30

Thank you! But, I don't get very clear why does exist this limitation. Do you know if there is any document where I could read about this limitation? By the way if I should split my method, suppose the next scenario: I got an object (suppose a cube) and I would like to modify their behavior making a translation or any transformation with respect to a second object, how could get access to the behavior of the second object accessing it from the first object? How to gain access to their variables? Does it have sense? Thank you for your time. Rafael On Thu, Jul 17, 2008 at 7:35 PM, Andreas Raab gmx.de> wrote:

Hi everybody Just an observation, it seems that the problem would be with the ports. For example in my University these port are *blocked*.

That's a limit of the compiler / byte code representation. Split your method into two and have one call the other instead. Cheers, - Andreas Rafael Rojano wrote:
