If you follow the book, the next paragraph on pg. 43 says:
The game will open, and you should be able to click on the cells and see
how it works.
Well, so much for theory. . . When you click on a cell, a notifier
window called the PreDebugWindow window appears with an error message!
As depicted in Figure 2.12, it says MessageNotUnderstood:
SBEGame»toggleState.
So I'm not sure it's supposed to work at that point. I think it's making
a point about the Debugger or something.
Incidentally I don't know why it says "and do it", as "new openInWorld"
seems to be enough.
You have another repository? OK.
At any rate this version seems to work alright. I always prefer to use a
working example and see how it works. I wouldn't sweat the details to
much. It sounds like you're getting the general idea of things.
HTH,
Chris
