I was reading about SqueakMap and came across the Swiki page for Alice
http://wiki.squeak.org/squeak/1861
Is anyone actively using Alice in Squeak?
- The page was last edited in 2004
- The first link is dead
- The second link goes to the new, improved Sun sponsored all Java version of Alice, which appears to be healthy
- The third link downloads a Ph.D. dissertation from 1997
- After the outdated info is a rant on the shortcomings of OpenGL. It just starts up, mid stream, "There is a serious design flaw in the lighting or rather the shading." This should be removed.
- A search on the Swiki for Alice includes a page on Falice which links to www.falice.com which is a parked domain.
Last but not least, when I try to load "FullImageProjectAlice" I get errors. Very likely I am doing something wrong.
Is this worth pursuing, or has Alice in Squeakland wandered off?

I do work on some aspects from time to time. The most recent work can be found here: http://squeaksource.com/Balloon3D.html

Not all of it! The Magma pages are current.
The wiki is a lot like the Squeak image. Parts of it are extremely outdated!
Of course, there is a fast way to contribute to the wiki. (ducks)

Aloha Gary, I remember the first time I saw Squeak, A;ice was pre-loaded in the image, so I did some digging. If you are really interested go to ftp.squeak.org and download a a 2.x version of Squeak. The 2.8 distribution has it installed. Be warned, the older Squeak interface might disappoint you ;)

Thanks, John. I downloaded the 2.8 image and changes files, and the V2 sources, and launched squeak with those. It opens fine, if old looking, and Alice is in there. I did a Wonderland new. and ran into an error:
mustBeBoolean "Catches attempts to test truth of non-Booleans. This message is sent from the interpreter."
self error: 'NonBoolean receiver--proceed for truth.'. ^true
The offending code is
areasRemainingToFill: aRectangle ^myCamera drawSceneBackground ifTrue:[aRectangle areasOutside: self bounds] ifFalse:[Array with: aRectangle]
where "bounds" in the ifTrue branch is highlighted.
A little more digging reveals that senders of bounds have something to do with AlignmentMorph, which is old stuff -- is the problem that ny VM is too "new.?"
Any suggestions as to how to proceed? Is there a way to cast "bounds" to the Boolean requirement? Sorry, that's my C showing.
Gary, There are several "Play with me" collapsed windows on the left hand side of the World. Open #7 to see the Wonderland editor in action.
While somewhat instructive, I think downloading v2 was not the best advice. (Though it does give one an appreciation of how far Squeak has come in the intervening years)
As Andreas, suggested, loading Balloon3D from squeaksource will give you the same thing in a version 3 image. The wiki page suggests that all you get is the 2D to 3D coolness, but it looks like all of the Alice code is in there. And Wonderland new still throws errors... And you will have to load other dependencies, VMMaker and FFI.
I am not an expert, just an interested fan, so please use my advice with caution.
Regards John

This looks as if myCamera drawSceneBackground is not returning a boolean. Certain messages, in particular ifTrue: ifFalse: ifTrue:ifFalse: whileTrue: and whileFalse: are inlined by the compiler into conditional branch instructions which operate on the object on top of stack. The conditional branches expect either true or false, the sole instances of True and False respectively. When they encounter something other than true or false the VM sends mustBeBoolean to that object. So look in the debugger at the object that has received mustBeBoolean. This was the result that myCamera drawSceneBackground returned, whereas areasRemainingToFill: expected a boolean.

I believe that is what makes Smalltalk a *strongly* typed language. No typecasting.
Loading the latest Baloon3D code from Squeaksource yields somewhat better results but there is a bit of post load actions that appear to be required.

I am able to get Wonderland new to run. But a warning message tells me that B3DPrimitiveEngine is not enabled (and I cannot as yet figure out how to enable it). Once Alice is running no graphics are rendered, just a blue screen(!) :)
