It's a great book, many thanks to the authors
Quinto game is a nice first app, I've learnt a lot from it but can't get it working fully. Have others here succeeded?
Problems:
1) the final line of the SBECell initialize method:
self turnOff
triggers a MessageNotUnderstood error
doesNotUnderstand: #turnOff
My interpretation is that the turnOff method is not part of the SimpleSwitchMorph super class
I wasn't sure how to solve this problem so I just commented out that line
"self turnOff"
and continued with the rest of the game
With
SBECell new openInWorld
a single cell appears and toggles a colour change with mouse clicks so it still seems to work at that level
2) pp. 43-5 of the book shows you how to use the debugger to fix the newCellAt:at: method by adding ^c to the final line
My problem is that even after I do this correction I still get the same
doesNotUnderstand: #toggleState
error
When I run the game
SBEGame new openInWorld
the grid appears ok
But when I click on a cell the MessageNotUnderstood box pops up with
doesNotUnderstand: #toggleState
at the top of the stack
I was wondering if others have had these problems and if anyone had ideas about what I could do to get the game working fully?
