You can get through the error, by rewriting VRMLStream class >> #initialize. Just remove the part that raises an error:

0 to: 255 do:[:i|                (DigitValues at: i+1) = (Character value: i) digitValue                        ifFalse:[^self error:'Digit value initialization failed'].        ].

The cause of the problem is that VRMLStream tries to duplicate a class variable of Character (DigitValues), but the code lacks changes done in Squeak 4.1, so the values differ. The real solution would be to use Character's DigitValues directly instead.

Thanks a lot in advance Bye Enrico PS: why Alice (in Squeak) because it was easy and funny and instructive... ;-)

I could load Balloon3D into Squeak 4.3 (had to fix a syntax error, because #. is not a valid symbol anymore), but it's not functional, because it relies on stuff that was removed long ago (e.g.: CurrentProjectRefactoring).

Yes, you should abandon using anything that requires VRML. That technology is dead. That project on SqueakSource is dated from 2004. Andreas Raab has moved on from anything related to VRML, and I imagine you might benefit from doing the same. What is he using in it's place now? Probably OpenGL or something.

I was looking at Carbon to learn about VMs. I went to ESUG, met the VM maintainers, and I got the message that I should move on to Objective C, because that's where they were going. So that's what I'm doing.

I'm involved in helping to bring out the next image. The idea that the new image has to be able to load in any code from anywhere in Squeak's past just depresses me. As a team and a community we only have so many resources and they need to be spent wisely on things like making the image smaller with each iteration.

I think expectations about such things need to be managed. At some point we've just got to say that that's the past. If you want to use old code then you need to stick with old images. If 4.3 doesn't accommodate VRML, I don't see how you can expect it to. The prospect exhausts me even before I've started working on the 4.3 release.

Please find out what Andreas Raab moved onto and use that.

Mostly I agree , but...

What is wrong on using some old as long works ?

Balloon3D could be loaded with hard work and maybe if we can have it could have a new user.

In short time he realize all you said is true and follow your advice.

But if we don˙˙t take users wishes , could loose he.

So , I try to have Balloon3D  in next FunSqueak, but give me time...

Edgar, I had already tried FunSqueak hoping to find Alice in it;-) In fact I wanted to point a friend of mine interested in trying 3D (high-ish level programming) programming to it

Thanks a lot anyway and GREAT JOB! Bye Enrico

Try http://ftp.squeak.org/various_images/FunSqueak/FunSqueak3.10alpha.7.zip Is a collection of many projects working on top of 3.10 image Unlucky us, projects as was in 3.10 is incompatible with trunk, but put high on my list how to export Alice an load into trunk.

Maybe not very orthodox and some of black art, but soon of later should work.

Edgar

I'll have a try. Thanks (to all helping on this thead) Bye Enrico

Have to agree with Edgar here, it's probably not hard to get it to load. Chris is right that he shouldn't have to put in work to make old packages work. That doesn't mean someone else couldn't put in that work, either by fixing the packages or Squeak, depending on what the problem is.

In this particular case, it was two trivial fixes to two of the Balloon3D packages. The syntax got more strict (#. is not accepted anymore), and the digitValue is now usable for lower-case characters too.

So if you use the 1.1.3 config it at least lets you load the packages. You probably need to do some debugging to make it really work again. Glad someone is using this still, it's a great piece of software :)
